Qihonghong recently launched CVN Z790D5 ARK FROZEN V20 a main board It is also the first ARK Ark series product owned by CVN, which is one level higher than the previous CVN GAMING cruiser series. It is the flagship product in the current CVN motherboard. Its main performance is overclocking, so Qihonghong is full of materials, which makes this motherboard greatly improved in power supply, expansion, heat dissipation, memory and other aspects. Next, we will evaluate this product.

one Introduction to Qicaihong CVN Z790D5 ARK FROZEN V20 motherboard

The design inspiration of the new generation Seven Rainbow CVN series comes from Starship As the flagship Ark product of Xingchen Sea, Qihonghong CVN Z790D5 ARK FROZEN V20 motherboard (hereinafter referred to as CVN Z790D5 Ark motherboard) In terms of appearance design, it is quite exquisite. First of all, the PCB is still CVN's signature pure white design, and the armor is designed in titanium gray, It tends to be dark gray but has a certain brightness, emitting a light metallic luster, and Like the wings of a warship The sharp edges and corners give the main board of CVN Z790D5 Ark a sense of mystery under the reflection of this advanced gray, and at the same time, it brings good heat dissipation efficiency.

The motherboard backplane also adopts a gray+white design, which gives a sense of uniformity. At the same time, CVN elements are screen printed, and RGB light bands are added, which is the only light effect of this motherboard.

In terms of power supply, this seven rainbow CVN Z790D5 Ark motherboard adopts a 14+1+1 phase power supply design. The PWM controller is RAA229131, which supports up to 20 phase power supply. The core 14 phase MOSFET uses Dr Mos design, model ISL99390, single phase support 90A, this set of power supply configuration is quite luxurious. At present, the stacking design of the top configuration in the seven rainbow motherboard can even meet the needs of the flagship 14 generation Core i9-14900K processor.

The entire VRM cooling armor is made of metal, which is thick and heavy, and has good thermal conductivity. In addition, a 6mm cooling copper pipe is built to penetrate the two pieces of cooling armor, further enhancing the cooling effect.

The CPU power supply interface adopts a dual 8pin design, with a more stable solid pin structure. The CPU single 8pin (4+4pin) general power output is about 350W, and most processors can be plugged in a single 8pin for use. It is recommended to plug in a full dual 8pin for flagship and overclocking, which can also reduce the pressure of the single 8pin wire and lower the temperature.

Seven Rainbow CVN Z790D5 Ark motherboard has four DDR5 memory sockets, which are reinforced with metal and are not easy to damage and durable. The official XMP frequency supports DDR5 7800+MHz, but in fact, this motherboard can overclock to 8000 or even higher frequencies depending on the CPU and memory.

In terms of expansion, this motherboard provides four PCIe slots, including two full-length metal reinforced slots. The top is PCIe 5.0 x16 bandwidth, which is also the strongest PCIe protocol at present, with a speed of up to 128GB/s. The bandwidth of the next metal slot is PCIe 4.0 x4, which allows most graphics cards to output full performance. In addition, there is a CIe 4.0 x4 short slot and a PCIe 3.0 x1 short slot for expanding I/O devices such as sound cards and network cards.

Dismantle the metal heat sink below. It can be seen that the main board of the Seven Rainbow CVN Z790D5 Ark provides four PCIe 4.0 M.2 slots, all of which are screw free and easy to assemble and disassemble.

There are four SATA interfaces, and a USB 3.2 Gen 1 Type-A front connector is beside it.

I/O area Seven Rainbow CVN Z790D5 Ark motherboard interface is very rich, and each interface is also marked, providing a total of four USB 2.0 interfaces, two USB 3.2 Gen 1 Type-A interfaces, three USB 3.2 Gen 2 Type-A interfaces, and one USB 3.2 Gen 2x2 Type-C interface with 20Gbps speed. One DP interface, one HDMI interface, five audio interfaces, one 2.5G wired network interface, one Wi Fi 6E wireless network card signal enhancement antenna interface, one five audio interfaces, one CLEAR CMOS button and one BIOS UPDATE button.

In terms of sound card, Qihonghong CVN Z790D5 Ark motherboard uses ALC 1220 sound card, which is a common sound card in high-end motherboards. Qihonghong also prepares a CVN customized filter cover to reduce interference, and it is equipped with a gold audio capacitor.

It is worth mentioning that this motherboard provides a USB 3.2 Gen 2x2 Type-C connector for the front interface. This interface can provide 10Gbps speed and support PD 30W fast charging, which is at least enough for iPhone 15 fast charging.

In addition, the main board of Qihonghong CVN Z790D5 Ark has prepared three sets of 5V ARGB pins and two sets of 12V RGB pins, which are sufficient for the lighting linkage of the whole equipment. Of course, this also needs to be used together.

two Seven Rainbow CVN Z790D5 Ark motherboard BIOS

Now let's take a look at the BIOS of the main board of the seven rainbow CVN Z790D5 Ark Seven Rainbow Motherboard After several iterations, the BIOS of has been greatly improved, which not only operates smoothly, but also has complete functions. The main menu page summarizes the whole machine information and monitoring operation, and can also adjust XMP, fan, startup sequence, intelligent overclocking and other modes.

The OC overclocking interface is first the frequency setting page, where you can adjust the frequency, power wall settings, and AC/DC values. It is very useful for the current 13/14 generation temperature control.

Needless to say, the memory setting interface. The functions of the Seven Rainbow BIOS have always been perfect in memory setting. Now we have moved the memory voltage options such as VDD and VDDQ here, and we can also set the timing, frequency, and small parameters.

CPU voltage and SA voltage can be set on the voltage regulation interface. CPU voltage supports constant voltage and voltage offset settings to reduce voltage.

The advanced interface mainly adjusts I/O functions, such as CPU hyper threading, virtualization, C status/AVX, etc.

three Practical test

Now let's start the practical test. The test platform is as follows.

First, we will test the memory overclocking capability of the main board of the Ark CVN Z790D5 of the Seven Rainbow. We will use AIDA 64 to test. First, we will turn on the XMP 7200 to see the read and write performance.

When the XMP 7200 is enabled, the memory read performance is 103.39GB/s, the write performance is 90350MB/s, the copy performance is 90350MB/s, and the delay is 76ns. The performance is OK. Next, we overclock the memory to 8000MT/s by adjusting the timing.

At this time, the memory read performance is improved to 115.61GB/s, the write performance is improved to 986893MB/s, the copy performance is improved to 101.11GB/s, and the delay is 68.4ns. Compared with 7200, the performance is significantly improved. However, it is known that the DDR5 memory parameter has a great impact on the content. Now we also adjust the parameter at the frequency of 8000MT/s to see the changes in the read and write performance.

The memory performance of the small parameter has been optimized. The read performance has been improved to 122.79GB/s, the write performance has been improved to 105.7GB/s, the copy performance has been improved to 108.161GB/s, and the latency has been reduced to 58.1ns. However, the regulation of small participation is really very difficult. It is only recommended that players who love to toss and turn try, otherwise it will be "a cup of tea, a packet of cigarettes, a small participation for a day".

Of course, we can eventually overclock this memory to 8200MT/s, and AIDA64 The overall performance has also been improved, but the application is not very stable. Some games will flash back and need some time to optimize.

Because 8200MT/s is unstable, the following game tests were conducted at 8000MT/s. Two 3A games, Tomb Raider: Shadow and Cyberpunk: 2077, were tested. These two games are very sensitive to memory and will report various errors whenever there is a problem.

Of course, this set of seven rainbow CVN Z790D5 Ark motherboard platform is very stable at 8000MT/s, completing two games benchmark The number of frames runs out. Under the 2K highest picture quality, Tomb Raider: Shadow has reached 202 frames, and Cyberpunk: 2077 has also reached 104.11 frames.

Next, we test the copying machine. The power consumption of the Core i9-14900K is extremely high. We use AIDA64 to copy both FPU and CPU.

We copied the machine for about 30 minutes, and the Core i9-14900K was stable at about 100 degrees Celsius. The main board of the Seven Rainbow CVN Z790D5 Ark has a very strong compressive capacity, and it has been running steadily at extremely high temperatures without any adverse reactions.

Finally, let's take a look at the official light controller of Seven Rainbows Software The light controller of Qihonghong is integrated in the iGame Center, which can adjust the light of the whole machine, graphics card, motherboard and memory. It is a necessary software for users who want to play with lights on the main board of Seven Rainbow CVN Z790D5 Ark.
