"I. Preface: equipped with the" new "b365 chipset, the new product of seven rainbow CVN bcvn b365m gaming Pro motherboard only costs 560 yuan
At the end of 2018, Intel released a "brand-new" chipset b365. From the name, it is an upgraded version of b360, but in fact, it is the vest of h270 chipset. The main reason is that Intel's 14nm capacity is insufficient. Therefore, h270 of 22nm HKMG + process is used to replace 14nm b360 to release 14nm capacity.
The h270 chipset can be regarded as a z270 that cannot be overclocked (in fact, the z370 can also be regarded as), so its specification and positioning are higher than b360. The following is the specification comparison of the two chipsets:
In terms of specifications, b365 chipset does not support USB3.0, while b360 can support usb3.1. In addition, the b360 motherboard supports 802.11ac Wi Fi, while the b365 does not. However, low-cost b360 motherboards rarely have integrated wireless network cards.
In addition to the above two points, b365 is stronger in other aspects. B365 chipset supports up to 20 PCIe channels and 14 USB interfaces, 8 and 2 more than b360 respectively; The b365 chipset supports raid, but the b360 does not. Another important point is that the me version of b365 is 11, that is, the b365 motherboard itself can support win7 system.
Seven rainbow company is also strongly supporting this cutting-edge mid-range product of Intel in the motherboard market. It has launched five motherboards equipped with b365 chipset at one go, and our fast technology has received the most high-end model - CVN bcvn b365m gaming pro.
Seven rainbow CVN bcvn b365m gaming Pro motherboard adopts mATX board design, with a size of 24.5 * 24.5cm. It adopts 7-phase circuit design, and 4 DIMM sockets support up to 64GB ddr26666mhz memory. In terms of expansion performance, there are two full-size PCI-E slots and one PCI-E 3.0x1c slot, two m.2 2280 interfaces and a special m.2 2230 interface for connecting WiFi / BT.
Since the b365 chipset cannot natively support usb3.1, the CVN bcvn b365m gaming Pro motherboard uses a third-party chip to make up for it.
In terms of heat dissipation, the frost condensation heat dissipation design scheme is adopted. Heat dissipation armor is installed at the power supply circuit of CPU, South Bridge and m.2 interface, which can effectively reduce the temperature of key parts.
Seven rainbow CVN bcvn b365m gaming Pro motherboard parameters are as follows:
At present, the seven rainbow CVN b365m gaming Pro motherboard has been sold online on the e-commerce platform. The official initial price is 699 yuan. During 618, it dropped by 100 yuan and only needs 599 yuan. There is a second kill of 499 yuan from 0:00 to 2:00 on June 18. It can be described as extraordinary value for such a motherboard with good workmanship and expansibility.
2、 Appearance: 7-phase power supply circuit + 3 m.2 interfaces
The packaging box is silver gray with the theme of aircraft carrier
Seven rainbow CVN bcvn b365m gaming Pro motherboard adopts m-atx board design.
As a motherboard positioned higher than b360, heat dissipation armor is indispensable. This motherboard is equipped with heat dissipation armor at the power supply circuit of CPU, Nanqiao and m.2 interface, which can effectively reduce the temperature of key parts.
In addition, the motherboard also provides two 12V ARGB 4Pin pins, which can connect ARGB lighting equipment on the market.
Next to the 24pin power socket, there is a front USB3.0 pin and three SATA 3.0 interfaces.
Although the CVN bcvn b365m gaming Pro motherboard does not have the common debug light on the high-end motherboard, it provides a more practical led debugging light.
As shown in the figure above, there are four LED indicators between the memory slot and the SATA port, representing CPU, memory, graphics card and boot device respectively. When the computer fails to start normally, the corresponding LED indicator will light up to tell you which part is wrong.
After removing the heat sink, it can be seen that this motherboard adopts a 4 + 2 + 1-Phase power supply circuit design. Among them, the CPU core is 4-phase power supply. Each phase power supply is equipped with 3 l.r.t Octopus MOSFETs, an F.C.C ferrite inductor and 10K black gold solid-state capacitor, which can provide more than 160W power consumption for the CPU core. In theory, it is not a problem to match i9-9900k.
Four DDR4 memory sockets, supporting up to 64GB DDR4 2666mhz memory. The memory also has a 2-phase power supply.
Surprisingly, this b365 motherboard also has a type-C interface.
There are also two SATA 3.0 interfaces, so this motherboard has a total of six SATA 3.0 interfaces.
As an m-atx motherboard, seven rainbow CVN bcvn b365m gaming Pro has rich expansion interfaces, including one PCI-E 3.0x16 slot, one PCI-E 3.0x4 slot and one PCI-E 3.0x1 slot. M. There are also two 2280 interfaces. In fact, one has a heat sink to assist heat dissipation. In addition, there is an m.2 2230 interface below, which can connect Wi Fi network card or Bluetooth module.
There are 4 SATA 3.0 standing on the left and 2 SATA 3.0 horizontal, which add up to a total of 6.
The audio part uses the alc892 sound card chip of Ruiyu electronics, supports eight channels, and is equipped with four special filter capacitors for Japanese Nichicon audio.
3、 BIOS analysis: XMP mode memory can reach 2666mhz
In the main interface, you can see CPU memory, motherboard and other information. Pull down the interface to set the language, which is available in Chinese, English and Korean.
In the Advanced tab, you can modify the settings of processor, fan policy, power supply, USB, hard disk, etc.
Energy saving, number of cores and hyper threading switches can be set in processor settings.
The chipset option can be set to turn on or off the core display, set the shared memory capacity of the core display, or set the core display to display alone and output the picture at the same time.
In the startup tab, we can set the keyboard case status, modify the waiting time, set the startup screen status, and adjust the startup sequence.
The CPU overclocking setting can only reduce the frequency.
Memory overclocking interface. You can select the default module, user setting module (custom setting) and XMP module.
However, b365 can only support 2666mhz at most. After XMP mode is turned on, the high-frequency memory will be set to 2666mhz.
Only the memory voltage can be adjusted, which is to increase the voltage based on the default voltage.
4、 Performance test: perfect i7-8086 / 9700K performance
The test platform is as follows:
1. Processor test:
Let's see if this motherboard can handle the strongest i9-9900k. After installing the 9900k, we ran a chess test. The results are as follows:
I9-9900k is a wonderful processor with 8 cores and 16 threads. The full core frequency is as high as 4.7ghz, but Intel limits its TDP to 95w. In the chess test, on the motherboard that does not support overclocking, it will have 28 seconds to make the power consumption exceed 95w, and then it will stabilize at 95w.
However, the 9900k can hardly reach the full core frequency of 4.7ghz when it runs high load test with 95w power consumption. In fact, in the chess test, the actual stable operating frequency of 9900k is 4.3ghz under the limit of 95w TDP.
This test also shows that the b365 motherboard can not play all the performance of 9900k, or any motherboard that can not overclock can not play the performance of 9900k. It must be z370 or Z390 with 9900k.
Let's test with i7-8086k:
Different from the 9900k, the i7-8086k with the same TDP of 95w has only 87W in the chess test, so it can run the test stably at the highest frequency of the whole core of 4.3ghz.
The final test result is 24186, which is equivalent to that of ASUS mxh motherboard.
From this test, we can see that the 95w TDP has a certain margin for the i7-8086k, and it also shows that there is no problem with the seven rainbow CVN bcvn b365m gaming Pro motherboard with processors of i7-8086k.
2. Memory performance test
After the XMP option is turned on in the BIOS of CVN bcvn b365m gaming Pro motherboard, the frequency of Zhiqi f4-3200c14d directly changes to 2666mhz and the automatic timing is 14-12-12-29 CR2.
ASUS maximus x hero motherboard needs to manually adjust the memory frequency to 2666mhz after opening the XMP option, and the timing is 14-14-14-34 CR2.
Since the default ring frequency of 8086k processor on ASUS maximus x hero motherboard reaches 4600mhz, which is somewhat higher than the 4000MHz of CVN bcvn b365m gaming Pro motherboard, ASUS maximus x hero is about 10% stronger in L3 cache test.
However, thanks to the lower timing, the memory read, write and copy performance of CVN bcvn b365m gaming Pro motherboard is comparable to ASUS maximum x hero.
5、 Temperature and power consumption test: the standby power consumption can be as low as 29 watts, and the power supply MOSFET is only 74 degrees under high load
1. Power consumption test
Test the power consumption of core display, standby with independent display, copying machine and 3dmark respectively. The power supply used in the test is cool Supreme V850 platinum gold power supply. The following data is the power consumption of the whole platform.
When equipped with Gigabyte aorus RTX 2080ti Xtreme large carving graphics card, the maximum power consumption running on 3dmark fire strike extreme platform is 370W. After deducting the power conversion loss, it is enough to choose a copper power supply with rated power of 500W.
When using core display for 3dmark fire strike extreme test, due to the very low CPU core utilization, the power consumption of the whole machine is only 62 watts. The standby power consumption is as low as 29 watts. When using the core display, you can't use one degree of power without turning off the power all day.
2. Temperature test
We use adia64 of the latest version 5.99.4900 to run FPU for 15 minutes to see if the heat dissipation can be borne!
The test adopts cool Supreme masterliquid 240 water-cooled radiator, with a room temperature of 26 ℃.
After running aida64 FPU program for 5 minutes, the processor temperature is 55 ℃, the voltage is 1.184v, the processor power consumption is stable at 95w, and the toaster frequency is 3.8ghz.
Since the power supply area is covered by the heat dissipation section, it is impossible to directly scan the temperature of the MOS surface. We use the temperature gun to read the temperature of the heat sink closest to the MOS. The measured temperature is 64 degrees, and then + 10 degrees is the MOS temperature. 74 degrees is not a very high temperature for MOSFET.
6、 Conclusion: 9700K good partner with high cost performance
In order to make b365 motherboard surpass b360 in specifications, qirainbow company takes great pains. CVN bcvn b365m gaming Pro motherboard is installed with a third-party chip, so it can support usb3.1. In addition, an m.2 2230 interface is designed to install a network card similar to Intel AC 9560ngw.
In our test, CVN b365m gaming Pro motherboard can perfectly support i7-8086k processor, that is, i7-9700k with power consumption equivalent to 8086k specification can also be well supported. Since the default full core frequency of i7-9700k has reached 4.7ghz, the performance improvement of overclocking again is very limited, which will lead to a sharp rise in power consumption and temperature. Therefore, for players who don't like to toss, 9700K + b365 is a combination of performance and price.
As for the i9-9900k, the full load power consumption of this u is far more than 95w, so it can not give full play to the full performance of the processor on non Z390 / 370 motherboards.
The seven rainbow CVN b365m gaming Pro motherboard is designed with three m.2 interfaces. Because the b360 chipset has more PCI-E channels, multiple m.2 devices connected can operate in PCIe 3.0 X4 mode without slowing down to PCIe 3.0 x2 mode like b360.
In terms of quality, seven rainbow CVN b365m gaming Pro motherboard has undergone 8 limit tests before leaving the factory, such as vibration, aging, constant temperature and humidity, hot and cold impact, drop, plug-in, compatibility and full load, so as to ensure the stable operation of the product. As for after-sales seven rainbow provides a 3-year warranty.
At present, the seven rainbow CVN b365m gaming Pro motherboard has been officially launched for sale on 8 e-commerce platforms. The official starting price is 699 yuan. During 618, it dropped by 100 yuan and only needs 599 yuan. There is a second kill of 499 yuan from 0:00 to 2:00 on June 18. For such a motherboard with good workmanship and expansibility, it can be said to be extremely valuable., Read the full text“
