Since the official announcement of processors Ryzen second generation (Pinnacle Ridge) been a couple of months, and then it’s time to get re-acquainted with them. As usual AMD has introduced two thousandth Ryzen series clearly hastily: ecosystem at the time of the announcement has not been definitively established, and this was especially true of motherboards. The new platform based on a set of logic X470 just started to go with conveyors manufacturers and were marred by various shortcomings, and the commercially available Socket AM4 old motherboard had BIOS quality optimization for micro-architecture Zen+. All this led to the fact that in the original testing of Pinnacle Ridge there are certain difficulties, which are generally smeared impression on the company AMD updated processor lineup. But to date, all fixable problems of the platform should already be fixed and therefore repeated testing is quite interesting and clearly worthwhile experience.

In its April review of desktop processors with the microarchitecture Zen+, we dealt with the flagships – 7 2700X and Ryzen Ryzen 5 2600X – chips, which have the maximum possible clock frequency, but differ very indiscreet energy appetites. Now we decided to go to new Ryzen second generation on the other side and look at the models that have the letter X in the title and have a much more restrained characteristics TDP: 65 W instead of 95 or 105 watts.

Somehow had the impression that the models “without X” in the first place are different from the older ones that do not support Extended Frequency Rangethat adds a couple of hundred MHz to the processor frequency at low load. But really it is not so: XFR 2 processors Ryzen Ryzen and 7 2700 5 2600 is supported, especially because it is closely woven with other technology avtoradgona, Precision Boost 2. The main difference of the younger members of the lineup Pinnacle Ridge is reduced to a reasonable quantities of energy consumption and heat dissipation. This feature makes Ryzen Ryzen and 7 2700 5 2600 so interesting options. On the one hand, these processors can be put in a compact and energy-efficient systems and to use them for a cheap cooling system, and on the other they remain fully-functional media micro Zen+ with a rather high real clock frequencies.

Moreover, Ryzen Ryzen and 7 2700 5 2600 as their older counterparts, can be easily overclocked due to the unlocked multiplier. Why be interested in such offers can buyers who just want to save a little. The official price of the chips without “overclocking” the letter X in the title for $20-30 lower and the performance of them, apparently, once set up properly, you can squeeze almost the same.

In this review, we’ll talk in detail about Ryzen 7 2700 – Junior OCTA core Pinnacle Ridge with the support of SMT. Formally, it is stated on polyvalence lower than Ryzen 7 2700X, the nominal clock frequency. But I think it is possible not to pay any attention. Check?

#7 2700 Ryzen in detail

The release of the second generation Ryzen did not bring in the CPU market no revolution. Fresh chips were enough qualifying upgrade media micro Zen, which was not even fixed the critical issues of the original design: limited overclocking potential, high latency inter-core interaction and a capricious memory controller. However, improvements to deny still impossible. The transition to more advanced production technology with a 12-nm rules allowed AMD to a few hundred megahertz to increase such frequency. Further development of technology of adaptive avtoradgona taught new processors aggressively to increase the frequency of low-flow at low load. In addition, improvements have affected the subsystem cache memory, which has reduced their latency, especially on the second level. All of this made the second generation Ryzen faster than the first in the performance of any applications and allows us to talk about progress.

And in the case of Ryzen 7 2700 this progress must manifest itself even more clearly than when comparing the older AMD processors first and second generation. After all, chips are artificially limited by the heat package, which belongs Ryzen 7 2700 crucial, as the turbo mode, the implementation of which in new AMD processors were noticeably improved. Advanced technology Precision Boost 2 (PB2) and Extended Frequency Range 2 (XFR2) not only got usedaboutgreater freedom in the interactive frequency control, but also learned to flexibly adjust the CPU speed at any load, any number of cores. That is why Ryzen 7 2700 and should be much better informed energy-efficient AMD osmeteria, Ryzen 7 1700, in which such intellectual technologies was not included the turbo mode only when the load on one or two cores, and the maximum achievable frequency was below 300 MHz.

One of the most important features of Ryzen 7 2700 – heat pack, a limited part of 65 watts. This is as much as 40 percent lower than the estimated heat release of the next member of the lineup, Ryzen 7 2700X. But there is no reason to say that senior and energy efficient Ryzen 7 of the second generation as seriously differ in clock frequencies, as heat dissipation. Even from the point of view of basic frequency Ryzen 7 2700X faster younger brother is only 15 percent, and the difference in maximum frequency given the turbo at all and is only 200 MHz. In other words, Ryzen 7 2700 does not seem somehow a compromise.

This is confirmed in practice. At full multithreaded load at rated speed Ryzen 7 2700 is able to hold a frequency of about 3.4 GHz.

Note that the supply voltage is approximately 1,037 In that provides extremely low power consumption and heat Ryzen 7 2700. Thus, according to the on-chip monitor, it does almost fit into the promised 65 watts.

Despite this, the boxed version Ryzen 7 2700 AMD completes the Wraith Spire cooler with RGB led, which according to the specifications compatible to the CPUs with a heat pack 95 watts.

And this means that a small acceleration Ryzen 7 2700 will be possible even with the boxed cooler. Although it is worth remembering that at frequencies above 3.9 to 4.0 GHz processors Ryzen second generation greatly increasing their thermal and power characteristics, so for good overclocking will require a cooling system, can keep the CPU around 200 watts of heat.

The nominal clock frequency and operating voltage — the only thing Ryzen 7 2700 differs from the older processors. It is compatible with Socket AM4-motherboards based on chipset X470 and based on older chipsets X370, B350 A320 and (after updating BIOS), and officially supports DDR4-2933 SDRAM (while unofficially is quite efficient with DDR4-3466). Moreover, considering the energy efficiency Ryzen 7 2700, you can use a cheap platform, equipped with high quality multi-phase voltage Converter. In sum, all this means that if you don’t focus on acceleration, Ryzen 7 2700 compared Ryzen 7 2700X allows you to save not only buying the CPU, but the motherboard cooling system.

However, you must keep in mind that the new algorithms PB2 and XFR2 that control the turbo, into account in their work not only CPU, but also parameters such as the instantaneous temperature and power consumption. And even more so now in the formula entered frequency characteristics of the voltage Converter on the motherboard. This means that in the system with a simple cooler and a cheaper motherboard real working frequency Ryzen 7 2700 will be lower than in a system with more quality components.

To treat this fact should seriously. In the case of Ryzen 7 2700 technology PB2 and XFR2 can add to the base frequency of the processor additional 900 MHz, which can affect performance dramatically. For example, when conducting experiments in the platform with the motherboard ASUS Crosshair VII Hero and a cooler Noctua NH-U14S we even managed to achieve what Ryzen 7 2700 working in nominal mode, when a certain load was faster than the flagship CPU of the previous generation, Ryzen 7 1800X.

To illustrate the variation of performance Ryzen 7 2700 at different loads we built the following chart, which displays the relative performance of AMD processors in the test Cinebench R15 rendering when using different numbers of compute threads. Indicators Ryzen 2700 7 taken as 100 %, the other results of the test are normalized relative to these values.

Indeed, when you work with a small number of computing threads Ryzen 2700 7 looks very attractive. In this case, it not only significantly outperforms Ryzen 7 1800X, but loses senior Ryzen 7 2700X only within 5 percent. Backlog as Ryzen 7 2700 from processors with higher heat pack is observed mainly in heavy multi-threaded load, when to develop a high frequency, it does not 65-watt limit.

Clearly you can see this in the following diagram, where we collected data on the dependence of the real frequency Ryzen 7 2700 of the load, which was observed in the testing in Cinebench R15 with the use of different numbers of computing threads.

Presents the results speak for themselves. When the load on one or two core Ryzen 7 2700 is able to develop a frequency up to 4.1 GHz, and the load on three or four cores allows the processor to work on frequency of 3,6-3,75 GHz. The further increase of CPU load causes the upper limit of the real frequency to get close to around a 3.4-3.5 GHz.

#Acceleration

As we have discovered in past testing members of the family Pinnacle Ridge, overclocking potential of these processors is very limited. Moreover, if we talk about the older Ryzen 7 2700X, then its acceleration “in the forehead” actually, in many cases, deprived of any sense, because it leads to a marked decrease in single threaded performance. However, in the case Ryzen 2700 7 the situation is somewhat different. Its nominal such relatively low frequency limits of the semiconductor chip and performance can be brought to the level of the older brother through the acceleration.

All conclusions about the overclocking features that we’ve made when meeting with Ryzen 7 2700X, fully apply to today’s hero. This means that the most effective frequency increase above the nominal value can not count. When crossing a 4-GHz milestone crystals Pinnacle Ridge starts to require serious nonlinear increasing voltage, which leads to a sharp rise in operating temperatures and heat dissipation. So if you expect to overclock Ryzen 7 2700 above 4 GHz, you’ll need a motherboard with the powerful Converter power and efficient cooler or even liquid cooling system.

For example, in our experiments we use the cooler Noctua NH-U14S, and with him we managed to overclock the test Ryzen 7 2700 to frequency of 4.1 GHz.

As you can see on the screenshot, the CPU core temperature is kept at a relatively low level — do not exceed 78 degrees. However, this does not mean that the frequency can be easily increased further. In this case, to ensure stability enough voltage 1.35 V, but even with these parameters, the real power consumption of a processor is estimated at 170 watts.

If you try to shift the frequency of the processor by another 100 MHz up to achieve stability of supply voltage is required to increase above 1,425 V. this dramatically increases the dissipation, and the cooler class Noctua NH-U14S to combat overheating of the CPU no longer enough. In other words, if 4,1 GHz and not the maximum possible acceleration, then at least limit appropriate. Besides do not forget that it is absolutely safe for health of semiconductor crystal Pinnacle Ridge are considered to be voltage not higher than 1.33 to 1.34, and the crossing of the border could damage the lifetime and reliability of the processor.

Here pertinently to remind, that overclocking Ryzen 7 2700X we also had to stop at the turn of 4.1 GHz. And this means that senior and Junior fosmidomycin Ryzen second-generation accelerated about the same. That is, having the processor Ryzen 2700 7, to achieve the performance level of the Socket AM4 flagship is possible. That he attracts: in the case of Ryzen 7 2700 save on the purchase, and then to regain the missing features of the processor through overclocking – quite a realistic scenario. The only thing: in this case, we highly recommend not to try to reduce the budget build due to the motherboard and cooler from them will depend largely on the success of overclocking.

Remember the body Design LUNA DNK-PRIME? For example, in early 2018, we showed that to build a compact and powerful PC with 8 core processor is quite real. The system uses Ryzen 7 1700 and NVIDIA. The weak point of the system turned out to be additional power X370GTN the first AM4-motherboard form factor mini-ITX. Since then it’s been quite a time, respecting all Board submitted its device of this size, and the company ASUS, which is not surprising, turned out to be in a leading position. Model ROG STRIX B450-I GAMING — a bird of a completely different flight. On the basis of this device is actually to collect and productive workstation, and fast gaming system. However, now you see for yourself.

ASUS ROG STRIX B450-I GAMING

ASUS ROG STRIX B450-I GAMING

#Specifications and packaging

At the time of testing ROG STRIX B450-I GAMING means far not the only mini-ITX-motherboard ASUS, which is suitable for processors Ryzen. So, in computer stores in your city you can meet similar solutions model ROG STRIX X370-I GAMING and ROG STRIX X470-I GAMING, which are based on older AMD chipsets. As you can see, the hero of today’s review uses a set of logic B450, but in this article I will explain why there is no sense to take mini-ITX-motherboard based on the older AMD chipsets. And yet I propose to get acquainted with the technical specifications ASUS ROG STRIX B450-I and GAMING equipment.

  • two custom SATA cable;
  • extension cable to connect the RGB tape;
  • plate for installing the M. 2 device form factor 2242 and additional screws for securing the SSD;
  • nylon ties;
  • external antenna from the wireless communication module;
  • ASUS Q-Connector to facilitate connection of the bodies of management of the case.
 

#Design and capabilities

Most motherboards form factor mini-ITX have a similar layout elements — this also applies to AMD AM4, and the LGA1151 platform-v2. So, the PCB with the sides 170 x 170 mm allows you to unsolder the two DIMM slots and one PCI Express x16. This modern device must have a quality power Converter, at least one M. 2 slot and allow to set arbitrarily large CPU cooler.

ASUS ROG STRIX B450-I GAMING problems installing monstrous cooling systems arose. I was Noctua NH-D15 and its Archon X2 — and both of the cooler is well placed in ecolocation space, not blocking the only PEG port.

In fact, I think that the layout of the components on the Board performed well. However, when you put such an assessment in the case form factor mini-ITX it is necessary to start including the type of the used computer case. Therefore, for those who are not familiar with the compact gaming systems, I suggest you first peruse the reviews the next section: Fractal Design Node 202 and Dr Zaber Sentry (Slim Desktop); Fractal Design Define Nano’s and Phanteks Enthoo Evolv Shift (Mini-Tower). Depending on the type of case the requirements for the location of certain components of the motherboard may vary.

In any case, there is no point to unsolder any connectors near the single PEG port. Because they will block either the graphics card (using the Tower-blocks), or a flexible ribbon cable, PCI Express (when using a Slim Desktop enclosure). Therefore, ASUS ROG STRIX B450-I GAMING a big part of the connectors are located on the right side — and it’s perfect (indeed, only possible) solution.

He PCI Express x16 slots are further reinforced. Metal frame called SafeSlot, according to ASUS, increases the strength of the port by 1.8 times under the load of fracture, and 1.6 times when the load on the pulling.

Right on the circuit Board has two SATA ports (two more connectors are wired closer to the chipset between the DIMM slots and M. 2) internal USB 2.0 and USB 3.1 Gen1, and a connector for connecting the bodies of management of the case. The presence of adapter Q-Connector, by the way, really helps when the build system is made in a really tight enclosure volume up to 10 liters.

A connector for connecting the F-Audio, so to speak, hidden — it is located next to the module Wi-Fi GO! The wire from the corps (regardless of format) I recommend to stretch along x PCI Express x16 — in this case, the building will be more accurate.

All three of the connector for the fan located at the top of the motherboard right above the CPU socket. Each connector has four pins, the Board changes the fan speed with PWM (4-pin connector) or without (3-pinoyme). One of the connectors intended for connection powerful pump liquid cooling system.

If we talk about the number of connectors for fans, it is the standard — I haven’t seen mini-ITX boards with usedona larger number of 4-pin ports. Thus three connectors, will not always be enough. For example, we can assemble a system in the case Fractal Design Define Nano’s, and this device allows you to install up to six 120mm fans. In General, when you create a really powerful, but compact system can not do without the splitters and additional controllers, allowing the use of more “Carlson” in the Assembly. Perhaps you should think about buying housing with the already installed hub. For example, well suited. H200i.

If we talk about the location of the connectors for fans, and there are different options. For example, in the housings Slim Desktop very often need to have only one impeller is the one that comes with the CPU cooler. However, for example, if you install in a Fractal Design Node 202 additional fans for cooling the graphics card, the length of their wires is not sufficient in order to without any extension cords to reach the 4-pin connectors ASUS ROG STRIX B450-I GAMING. In the case of Mini Tower we can face exactly the same situation, if you want to install fans on the bottom or in the lower part of the front panel. That is why, in my opinion, one of the connectors to connect fans better be positioned in the area of the SATA ports.

Next to the onboard fan connectors are wired connectors 5 – and 12-volt RGB strips. You can manage this by using AURA Sync. The Board itself is also backlit — RGB-LEDs located throughout the right side of the device.

ASUS ROG STRIX B450-I GAMING is unique in that the company’s engineers were able to place two M. 2 port. The main connector for SSD drives of this format is on a kind of pedestal is done on purpose, as under it is the chipset cooled by a small aluminum radiator. The port supports the installation of discrete devices with a length of 42, 60 and 80 mm and operates in the SATA 6GB/s or PCI Express 3.0 x4.

The photo above shows the drive with the installation of further cooled aluminum radiator.

The second M. 2 port soldered on the reverse side of the PCB. Immediately say, that this location will not always be successful. It is no secret that modern NVMe SSD is very strongly heated. It may well be that in the case of any type of SSD, the result will be sandwiched between the circuit Board and the protective wall of the housing. As a result, the SSD will warm up and throttling even stronger. Moreover, in this connector, you can install the drives without all of the radiators and thickening.

In the second M. 2 on the Board, you can install the drives with a length of 42, 60 and 80 mm. Port will only work in PCI Express 3.0 x4, and when it is used the PCI Express x16 slot, intended for graphics cards, is translated in a mode x8.

By the way, the ASUS ROG STRIX B450-I GAMING there is a third M. 2 port with the key “E”. It the default network card with a marking WCBN808L-AD, supporting 802.11 a/b/g/n/ac and Bluetooth v4.2 through controller Realtek RTL8822BE. For a wired network in ROG Board meets Gigabit Intel I211-AT, and for sound Realtek S1220A. Audio components are on the same extra Board, soldered the main M. 2 port. It is composed of a special audiophile-grade Nichicon capacitors, headphone amplifier.

To conclude the topic of interfaces ASUS ROG STRIX B450-I GAMING, I note that the I/O panel includes two USB 3.1 Gen2 A-type is an undeniable plus of the device. For example, the previously tested ASUS ROG STRIX Z370-I GAMING has no such connectors.

 

Field-effect transistors included in the power Converter are cooled by one aluminum radiator medium size. The basis of the power subsystem is a PWM controller ASP1405I. Six phases, which include transistors Infineon Technologies IR3553, form a regulator for CPU Voltage. Another MOSFET IR3555 — provides the SOC Voltage and the integrated graphics core processors Ryzen 2000G.

Shots lowlight I will give the second part of the article.

Review motherboard MSI Gaming Pro Carbon B450 AC: save lossless

Samsung J7 V just $5 mo. New device payment purchase req'd. Plus, free shipping.

Presented at the end of July, the chipset AMD B450 did not introduce anything fundamentally new in comparison with the predecessor chipset AMD B350. Yes, there is support for the technology of dynamic overclocking Precision Overdrive Boost, technology of data cache StoreMI, and support for AMD processors with core Pinnacle Ridge. However, without the first two the majority of owners of motherboards with B350 easy to do and now, and support for new processors they can get a simple BIOS update. Differences from the flagship X470 slightly more tangible: less USB and SATA ports, six PCI-Express and eight, as well as on the boards with the B450 it is impossible to organize NVIDIA SLI.

But the new chipset, according to the developers, should make the motherboard based on it is more affordable than in the case X470, with almost the same functionality and full support for overclocking. This did not fail to take advantage of all the major manufacturers, has announced a new series of boards. For example, ASUS has released seven new models, Gigabyte – six, ASRock – five. But the most distinguished company MSI, who presented twelve versions of their products for a given set of system logic AMD. The flagship series has become a model B450 Gaming Pro Carbon ACthat we can examine and test.

It should be noted that the retail price of this Board is nearly twice lower than the cost of the recently tested MSI X470 M7 GAMING AC, who also heads his series on AMD X470. Therefore, a comparison of these products in the course of today’s article seems quite interesting. Let’s get started.

Note that this model is the most advanced among the solutions of MSI chipset AMD B450, however it is much cheaper, comparable in performance to AMD boards X470 of the same manufacturer.

Externally, the new B450 MSI Gaming Pro Carbon AC looks completely normal and does not indulge the users with bright colors. Almost black PCB with dimensions of 305 × 244 mm you can only select silver the PCI-Express slot and red lettering on the cover of the audio codec.

 

Everything else is done in one color with the PCB, including the radiators, stylized as carbon. By the way, the VRM circuits they have grown substantially in size in comparison with radiators motherboards MSI AMD B350.

 

Backboard offers eighteen different connector port types: USB ports and PS/2, two video output, two connectors for antennas of the wireless communication module, the wall outlet and the audio jacks.

This also displays the Clear CMOS switch, which, by the way, we did not have to use even when a poor choice of BIOS settings — in which case the fee itself resets the settings to the standard.

All the radiators attached to the PCB with screws and plastic covers here and not at all (which, by the way, can not but rejoice). Therefore, in order to “strip” the cost to the PCB, it only took a couple of minutes.

First of all, before component analysis B450 MSI Gaming Pro Carbon AC, here is a layout of the elements on the PCB of the operating instructions.

 

To look for some differences and peculiarities in the CPU socket format Socket AM4, as practice shows, it is meaningless. All boards it completely standard.

Supported payment processors include all CPU manufactured in this design. And this is true for all BIOS versions, starting with the first.

In the power supply system of the processor uses eight phases (in fact, correct to say 4 × 2). Two more phases are reserved for power delivery to the CPU NB/SoC.

For the power management of the processor on Lenovo B450 Gaming Pro Carbon AC meets PWM controller RT8894A production Richtek.

Beside the CPU VRM is a small block with connectors and jumper.

On her appointment in the instructions to the Board and on the website there is no word, so we can only guess that with it are governed by the limits of some stress. Write your version in the comments to the article.

To ensure the Board and its components power it uses standard connectors with 24 and 8 pins, as well as an additional four-pin connector.

 

They are all oriented with latches on the outside.

Released on Taiwan chipset AMD B450 applies to version B2 and is dated to the 12th week 2018 (mid-March).

It combines with the AMD processor Ryzen opportunities given in the diagram below.

Since MSI Gaming B450 Carbon Pro AC applies to boards in the medium price range, branded metal sheath Steel Armor and extra soldering points to the PCB, as in the top MSI, not here. But DDR4 Boost technology, which provides memory-increased stability and at the same time allowing to reach higher frequencies during overclocking, the Board supported.

Officially declared support for DDR4 memory modules with a frequency 3466 MHz, but in BIOS the available range of frequencies up to 4133 MHz. The list of tested on-Board modules is already huge and continues to fill with new models with a-XMP.

Food memory is implemented by a two-phase scheme.

Recall that the maximum amount of memory on Board with AMD B450 can reach 64 GB, and MSI Gaming B450 AC Pro Carbon is no exception.

Board is equipped with only one full PCI Express 3.0 x16 with a metallic shell of Steel Armor. It can operate in modes x16 or x8, if the cost to install two graphics cards on GPUs from AMD. In this second video card is installed in slot PCI Express 2.0 x16 with only 4 lines. Such is the strange will be AMD 2-way CrossFireX.

As a result, NVIDIA 2-way SLI motherboard/chipset is not supported (“green” graphics card with PCI-E x4 don’t work). The remaining three slots are designed for expansion cards are PCI Express x1 2.0.

Like most other MSI boards, the switching of modes of the slots provide multiplexers ASM1480 production ASMedia.

Four of the six SATA 3 bandwidth of up to 6GB/s on Lenovo B450 Gaming Pro Carbon AC implemented by the chipset AMD B450 and two – processor lines, with the result that they are forced to share resources with the first M2_1 port. So I have to choose: or SATA5 ~ 6 ports will be or M2_1.

Moreover, this choice is not very pleasant, since the upper M2_1 on the Board is called a Turbo M. 2 supports SATA and PCI-E NVMe drives types 2242/2260/2280/22110 and has a radiator Shield FROZR.

In other words, to abandon the port and storage it is unlikely that anyone will want. Today, however, even in expensive systems rarely use more than four SATA drives, and in the budget. So ports should be enough.

Second М2_2 connected to the chipset and only supports drives PCI-E 2.0 x4 types 2242/2260/2280, and the radiator is provided.

Concluding the topic of ports for drives, say a few words about USB. Overall B450 MSI Gaming Pro Carbon AC comes with 12 USB ports, six of which are displayed on the rear panel — and the same can be connected to the connectors on the PCB. On the panel there are two USB 3.1 Gen1, two USB 2.0 and two SuperSpeed USB 3.1 Gen2 (Type-C and Type-A). With the internal connectors of the motherboard can take the four USB 2.0 and two USB 3.1 Gen1. Third-party controllers for USB card is not received — using only the resources of the chipset and processor. We will add that at the program level are supported by proprietary technology MSI X-Boost, MSI Super Charger and Double ESD Protection.

About the network interfaces. On Lenovo B450 Gaming Pro Carbon AC is present Gigabit Ethernet controller Intel l211-AT the release of the end of 2012, worth just over two U.S. dollars. However, nobody says that is bad.

At the hardware level supports technology of protection against voltage surges and static electricity, Protect the LAN, and software – intelligent control of network traffic through the app the MSI GAMING LAN Manager. A conventional controller, for household needs it is quite sufficient, but still we would like to see in motherboards even average level any progress in this area and the introduction of dezetilirovanny network controllers.

Wireless network interface Board is implemented by the controller Intel Dual Band Wireless-AC 9260 release the end of 2017.

It provides Wi-Fi 802.11 a/b/g/n/ac dual band — 2.4 and 5.0 GHz with a bandwidth of up to 1.73 Gbit/s, as well as Bluetooth 2.1, 2.1+EDR, 3.0, 4.0, BLE, 4.2 and 5.0.

Sound B450 MSI Gaming Pro Carbon AC presents 7.1-channel HD audio codec Realtek ALC1220, protected from electromagnetic interference by an aluminum cap.

In the original concept MSI Audio Boost 4 includes not only the shielding of the processor, but also audiophile-grade capacitors Chemi-Con, dedicated headphone amplifier, protection against clicks, the individual layers of the PCB for the left and right audio channels, as well as isolated from the rest of the items on PCB area of audio.

Budget motherboard got gold-plated contacts audio software support for surround sound technologies in speed and performance Sound 3.

Controller Nuvoton NCT6797D-M Board can simultaneously control up to six fans with PWM support.

One of the connectors has a current up to 2 A — it is designed to provide power, for example, energy-intensive pumps liquid cooling systems. Note that from the point of view of placing of hull and CPU fan connectors are distributed on the PCB pretty well.

Backlight on Lenovo B450 Gaming Pro Carbon AC is implemented by LEDs under the chipset and the line of LEDs on the back side of the PCB in the area of RAM slots.

Branded app MSI Mystic Light will help you to choose one of 16.8 million colors and over a dozen different modes of illumination.

In addition, the backlight can be extended by connecting an external led strips, for which the Board has three connectors.

Unfortunately, the indicator POST-codes on Lenovo B450 Gaming Pro Carbon AC no, but it is partially replaced by four LEDs MSI EZ Debug, soldered the RAM slots. The bottom edge of the PCB Board took the USB connectors, front panel connectors of the case and the audio and other instruments.

A distinctive feature B450 Carbon Pro Gaming AC from MSI motherboards of the previous generation are enlarged radiators on the VRM circuits. Especially their size is impressive, the radiator of the power supply circuit of the CPU core.

And as it turns out, this is done not by marketers for design and beauty, as often happens. We make sure the test portion of the article, and go over your BIOS.

#Opportunities UEFI BIOS

At the time of testing B450 MSI Gaming Pro Carbon AC was only available for two version of BIOS: 1.08 July 4, 2018, with support AGESA PinnaclePI-AM4 1.0.0.2 and 1.10 from 15 August 2018 with the support AGESA Code 1.0.0.4 C and some optimizations in the memory handling. We tested the charge on both the latest BIOS and no difference in overclocking the CPU or memory is not revealed.

As in previous MSI starts the shell in a simplified EZ mode (here and below we present a number of screenshots already with overclocking CPU and memory, not by default).

When you press F7, you can switch to advanced mode to access the six main sections with settings and integrated utilities.

The main section, Settings, incorporates the controller settings of the Board, security and boot options, and saving and loading settings.

 
 
 

OC – so short and sweet is the main section with the overclocking settings the motherboard, CPU and memory. Here we recommend you immediately switch to the Expert mode with additional settings.

 

It has everything you need for overclocking of CPU and RAM, including eight stabilization modes stresses the CPU and SOC. The core voltage of the processor can be changed in the range of 0.900 to 1,550 In increments of 0.0125 V SOC in the range of 0.900 to 1,300 In the same step, and the RAM – from 0,800 to 2,000 In increments of 0.010 V. in addition, change some more minor tensions.

There are also sub-subsections with detailed information about the installed processor and memory modules.

 
 

A separate section is configuring the technology CPU.

As for RAM, here B450 MSI Gaming Pro Carbon AC will give odds to many competitors. First, despite cypselae restriction 3466 MHz, a memory frequency of up to 4200 MHz. Another thing that is compatible with AMD Ryzen memory at this frequency you until you find (and if you find, you are not forced to work stably at this frequency), but for the future is obvious. Second, the BIOS pre-flashed more than 20 sets of memory settings (frequency/timings) for overclocking.

 

However, this setting even its name “Memory TryIt!” alluding to the fact that there are no guarantees, but as a brand features the MSI boards are quite interesting. Thirdly, if you don’t rely on automatic selection of the settings, to manually change all the timings available RAM, including the secondary and deeply hidden. Below we present only two screenshots, but in practice they are twice as much.

 

The possibility of creating six profiles of BIOS settings that you can save for later use, but to upload to a USB flash drive or download from it, should simplify the overclocking.

Not disappeared and the usual utility Hardware Monitor where you can adjust each of the five plugged in for the fans as well as real-time monitor core temperature, and voltage.

The only thing I would like to wish the MSI engineers, is to increase the number of points on the fan curve from four to six, so you can adjust speed more smoothly.

In conclusion, the BIOS will remind him about the built-in browser of the motherboard.

Here without loading the operating system and opening the system unit can identify which components are installed in the cost. We will add that when you exit the BIOS displays all changes made to it.
