one Seven Rainbow B650M GAMING FROZEN motherboard introduction

Now let's officially evaluate this motherboard. First, let's take a look at the appearance of the Seven Rainbow CVN B650M GAMING FROZEN motherboard. This product's appearance is as CVN style as always. The battleship elements are getting better and better. The white part is more pure, and the gray steel color matching is also just right. The channel element and the No. 65 name LOGO bring the entire motherboard's appearance to a new height. The board type is still the standard M-ATX board type, which is suitable for matching with various white cases.

The backplane coating of this motherboard has also been carefully designed. The channel overtime and white coating design are clear, covering the circuit components, without any sense of compromise.

First, let's take a look at the power supply. The mainboard of Qihonghong CVN B650M GAMING FROZEN adopts a 12+1+1 phase power supply design. The PWM controller is RT3678BE. The core power supply 12 phase adopts a DrMos design. The model is AOZ5516QI, and the single-phase output is 55A. This set of power supply is enough to meet the needs of the current Sharp Dragon 7000/8000G series processors.

The CPU powered VRM area is covered by two metal heat sinks, and the bottom copy MOSFET area provides two additional sets of heat conduction pads.

CPU power supply interface adopts 8+4pin design, and 8pin interface adopts solid pin.

Seven Rainbow CVN B650M GAMING FROZEN motherboard has four DDR5 memory sockets, which supports 7600 (OC) memory and EXPO. However, considering the problem of AMD processor FCLK, the DDR5 memory between 6000-6400 is generally enough.

In terms of expansion, the Qihonghong CVN B650M GAMING FROZEN motherboard is equipped with two long slots and one short slot. The two long slots are equipped with metal armor. The top one is PCIe 5.0 x16. Generally, the unique one is preferentially installed in the entire slot. The bottom one is PCIe 4.0 x4, and the short one is PCIe 4.0 x1.

The graphics card slot is surrounded by two M.2 slots and is equipped with an M.2 thermal armor. These two M.2 slots support the PCIe 5.0 protocol at most. At present, the M-board with dual PCIe 5.0 slots is relatively rare.

There are four SATA expansion interfaces in total, which support RAID 0, RAID 1, and RAID 10 disk arrays.

The I/O area is pre installed with a bezel, and each interface has standard information. A total of four USB 2.0 interfaces, two USB 3.2 Gen 1 Type-A interfaces, one USB 3.2 Gen 2 Type-A interface, and one USB 3.2 Gen 2 Type-C interface are provided. Since the Reelung 7000 series is equipped with a core display at the beginning, a DP interface and an HDMI interface are also prepared, It also provides one 2.5G network interface, Wi Fi 6 antenna interface and six audio interfaces.

In terms of jumpers, in addition to the conventional USB, audio, and fan pins, a total of two 5V 3-pin ARGB light pins and two 12V 4-pin RGB light pins are equipped. With the iGame Center of Seven Rainbows and the supported hardware, light effect linkage can be achieved.

Seven Rainbow CVN B650M GAMING FROZEN motherboard is equipped with a motherboard self check lamp beside the switch jumper at the bottom to quickly troubleshoot related hardware when problems occur.

The sound card is the classic ALC897, which supports 7.1 channels, and is equipped with a filter mask to resist interference.

two Seven Rainbow CVN B650M GAMING FROZEN motherboard BIOS

At present, the BIOS of Qihonghong is continuously upgraded. The interface of the CVN B650M GAMING FROZEN motherboard is still the classic graphic UEFI style of these two generations. All functions are complete. You can view some information in the EZ main menu, adjust the startup item, XMP, fan, and performance mode.

The overclocking OC interface mainly adjusts the processor frequency, memory and voltage. Our U locks the frequency, so the frequency interface has no options. In addition to conventional XMP settings, the following memory interface can be optimized for small parameters.

The advanced interface is mainly used to adjust I/O settings. At the same time, the official default overclocking function PBO of AMD is also set here, as well as SOC voltage, memory frequency division and other settings.

The BIOS interface can be upgraded through mobile devices,

The BIOS supports three languages, including simplified Chinese.

three Practical test

Next, we will conduct a practical test, and the test platform is as follows:

First, let's test the memory and use AIDA64 To test, first test the performance of XMP memory on Qihonghong CVN B650M GAMING FROZEN motherboard. This motherboard can easily enable two Zhiqi memories to achieve XMP 7200MT/s.

We tested 6200MT/s and 7200MT/s at two frequencies. The difference in memory read performance between the two frequencies is not obvious, and the write and latency will be improved to some extent. At the same time, we also tested the frame performance of three games at XMP 7200MT/s. The resolution is 1080p, and the default image quality is the highest.

At this time, the average frame number of Tomb Raider: Shadow is 305, the average frame number of Cyberpunk: 2077 is 184.57, and the average frame number of Extreme Racing: Horizon 5 is 176.

Now let's test the performance of the EXPO memory on the mainboard of the Qihonghong CVN B650M GAMING FROZEN again. Using the Rakesha Warlord Blade to test, the EXPO frequency of this memory is 6000MHz. At the same time, we test the memory read and write performance changes after overclocking to 6400MHz.

As AMD's own memory standard, this set of EXPO memory has a lower timing, so AIDA 64 performs better in latency and reading than the XMP parameters above, and 6000 EXPO writes better than the XMP 6200. This also shows that DDR5 memory frequency has little impact on AMD platform, and timing is more important.

We also optimized the 6400MHz EXPO memory, adjusted the FLCK frequency to 2100Mhz, and set UCLK=MEMCLK to turn off frequency division.

After the tuning and setting, the 6400MHz EXPO memory read and write performance has further improved. The read performance has exceeded 6WMB/s, and the write performance has also reached the level of the XMP 7200 above. The latency has increased compared with the two frequencies of EXPO above, but it is also lower than that of the XMP.

We also tested the frames of three games again. Compared with XMP 7200, the optimized 6400MHz EXPO memory increased the average frames of Tomb Raider: Shadow from 305 to 312, Cyberpunk: 2077 from 184.57 to 186.44, and the average frames of Extreme Speed Race: Horizon 5 from 176 to 181.

PBO test:

The processor we use is AMD Reelong 7 7800X3D. Although this model locks manual overclocking, it can support PBO, so you can enable PBO to enhance the performance of overclocking. As mentioned earlier, the PBO option can be found in the advanced options in the BIOS of the motherboard of Seven Rainbow CVN B650M GAMING FROZEN, and we have optimized it.

However, after using R23 for performance testing, we found that the AMD Reelong 7 7800X3D is not sensitive to PBO optimization.

It can be seen that there is no change in the gap between before and after the adjustment of the AMD Reelong 7 7800X3D. After the adjustment, the single core performance has increased, but the multi-core performance has decreased a bit. Therefore, the PBO of the X3D series can be ignored, as long as you know that the main board of the Seven Rainbow CVN B650M GAMING FROZEN can support this advanced play method.

Finally, we test the stability of Qihonghong CVN B650M GAMING FROZEN motherboard by copying as usual. Using AIDA 64 to copy CPU+FPU

After an hour of copying, the temperature of the AMD Sharp Dragon 7 7800X3D was about 63 ℃, and the whole platform had no adverse reactions. The mainboard of the Seven Rainbow CVN B650M GAMING FROZEN was able to withstand the baptism of high-pressure loads, giving full play to the performance of the AMD Sharp Dragon 7 7800X3D.

four Write at the end

In general, the Qihonghong CVN B650M GAMING FROZEN motherboard, as a M-ATX board type B650 motherboard, is designed to meet the needs of mainstream users of the Reelung 7000 platform.

At the same time, it can be seen from the BIOS design that the Qihonghong motherboard is getting more and more late. It not only has the same complete and smooth graphical UEFI interface as the platform system, but also the functions of the Qihonghong CVN B650M GAMING FROZEN motherboard BIOS are very complete and declining, which can easily realize CPU, memory overclocking, voltage regulation PBO settings, frequency division, dual CCD, cache and other in-depth optimizations enable users to further improve computer performance through these operations.

Seven Rainbow CVN B650M GAMING FROZEN motherboard, as a pure white M-ATX small board, is also rare in the B650 motherboard, which brings you a new choice of white installation. At present, this motherboard is priced at 999 yuan, starting from 899 yuan after full reduction of promotion, and the price of this material has exceeded 1000 yuan for other brands. Seven Rainbow CVN B650M GAMING FROZEN motherboard is still very cost-effective, Users with recent installation needs are worth considering.
