Silver の soul: toss Z270 new platform, and then play double card crossfire

Although the performance of each generation of video card performance is very stable, there is not much surprise in the improvement of the performance of the PC platform. Instead of saying that Intel is not squeezing toothpaste, it is better to say that there is no “high” point, but it still loves the PC platform. I feel like I’m playing with personalization and I can also get myself to this “high” point. So after deciding to install the Z270's new platform, I would like to add an element of my favorite anime work, Gintama.

I feel that the animation is very special and it is a combination of Tucao, inspirational, touching, and passionate. This mixed effect is very weird, but it is also unforgettable. At the end, it is utterly unstoppable. It looks like this year's live-action movie will be released, and is still looking forward to it. what!

Talk back to the PC, the specific hardware is as follows:

CPU: i7-7700K

Motherboard : ASRock Z270 Killer SLI

Graphics: XFX RX 480 4G Black Wolf Evolution X2

SSD: LiteX Series V5S 256G SATA3 Solid State Drive

Memory : GALAXY GAMER DDR4 2400 8GX2

Chassis : Josper RM4 Silver

Power Supply : XFX 650W XTR650 Power Supply

Radiator: Kyushu Captain Fengsong 240 (White) CPU Radiator L

Added Gintama metal stickers and Q version to add some self-entertainment elements.

Some details

This year squeezed toothpaste out i7-7700K, Kaby Lake architecture, silent frequency 4.2G, Turbo 4.4G, single core Turbo 4.5G. Not too greedy, so I started with a piece and I'll see how it looks.

The mainboard is ASRock's Z270 Killer SLI. ASRock's KILLER series motherboards have been separated from the "Fitratte" family this year, making it a mid-range mainstream product.

ASRock Z270 Killer SLI Motherboard (Intel Z270/LGA 1151) 1299 yuan Jingdong direct link

The main board is based on black and white colors. The "K" logo on the motherboard is very obvious, but don't think that it is equipped with a KILLER card. In fact, it has returned to Intel's network card.

The biggest difference between the Z270 and the Z170 is that the Z270 has four more PCI-E channels, so the board has basically one more M.2 interface and can plug in two M.2 devices. Even if the players have installed dual graphics cards, they still have You can play Ultra M.2 RAID. There will be a chance to play the intel Godama - Optane

The left side of the motherboard (including the IO interface) plus a protective cover, Yan added a little, but the CPU's mos heat sink is much simpler, 8PIN auxiliary power supply, four memory slots up to support DDR4 3733 + (OC), PCI There are two PCIe 3.0x16 (dual card is X8 + X8 slightly), four PCIe 3.0 x1.


The I/O section provides a dual-use port for PS/2 keyboard and mouse, five Type-A USB3.0, and one Type-C usb3.0 (ASMedia ASM1153 provided).

The display output provides a DVI-D and an HDMI 1.4 interface. The audio output provides 5 sets of interfaces and a set of fiber interfaces.


The audio output uses ALC892 with Nichicon sound capacitor, which is called Nichicon sound effect directly, and the PCB is cut to reduce interference.


From the name Z270 Killer SLI, SLI is definitely supported (full name: NVIDIA Quad SLI, which requires a fee), and it certainly supports AMD Quad CrossFireX, but this generation of SLI has a high threshold, starting with GTX1070, which is my minimum. The reason for choosing CF.

At the same time, the pci-E slot uses alloy protection to prevent the card from falling too badly.


The front USB3.0 port is located next to the memory and 24pin power port, above the SATA port.

The storage expansion provides six SATA3 (90 degree corners) and two sets of Ultra M.2 (PCIe Gen3 x4, 32 GB/s), supporting dual M.2 RAID.0 arrays. Supports various types of 2230, 2242, 2260, 2280 specifications. You can switch between SATA or PCIe channels. If you select SATA channels, they will occupy SATA port 5 and port 0 respectively.

Although we did not continue to use the KILLER card, it seems that ASRock wanted to inherit this name. The armor on the left side was for Intel's Gigabit LAN solution. The network adapter chip was the Intel i219v.

Counting the number of CPU power supply is a total of ten phases, simply understand that the 10 phase is also possible, in order to listen to the complex look down.

PWM control chip is Intersil ISL95824, this chip can provide up to 4 +2 times phase, but online search data, Vcc (CPU core power supply) controlled by Intersil ISL95824 and VccGT (display core power supply) is 3 +2 phase, that is The left side supplies power to the core. Each phase consists of 2 upper bridges and 2 lower bridge MOSFETs. Each phase uses 2 inductors, and then it is supplied with a 6-phase core power through a phase multiplication. The display power supply is 1 upper bridge and 2 The lower bridge MOSFET consists of one inductor per phase for a total of two phases; in addition, VccSA and VccIO are each one phase, including one upper bridge, one lower bridge MOSFET, and one inductor. The capacitor uses a Japanese Nichicon 12K black gold capacitor. The allocation of each phase will not say anything. It looks a bit dizzy. Calculate the distance in the rules.

PCH heat sink is surrounded by LED light effects, the motherboard can also be directly connected to the 5pin light bar, through a dedicated AURA RGB LED for RGB adjustment, looks like the same technology as the big brother Assos.

The memory is GALAXY GAMER DDR4 2400 8G, 1.2V operating voltage, timing 16-16-16-36-2T. Although the overall color is silver-white, it is a bit monotonous, so I chose blue memory to add it.

The motherboard, CPU, and memory fit together successfully.


TLC SSD became the mainstream and chose the Lite-Core V5S 256G SATA3 SSD, Huirong SM2258G master, and Hynix 16nm TLC flash memory. Of course, mechanical hard drives are also required.

The front said that playing SLI threshold is high, the minimum consumption GTX1070, this can really exceed my budget. So you want to play dual cards or choose A card.

Of course, I also know that dual cards are effective, and it is difficult to achieve the situation of 1+1=2. There is an eight-nine-nine achievement that is very high crossfire efficiency; and if the game is not good for dual-card optimization, comparison The improvement effect of a single card is less poor. However, I still love tossing people. I haven’t tossed my cards for a long time. I still want to toss them again. Simply speaking, I’m going to have to play with dual cards.

The price of RX480 4GB is 3,000, slightly more than GTX1070; the price of RX480 8GB is 3600, more than the price of GTX1070. After a long period of tangling, 2 RX480 4GB are still used. Of course, the future of A-card warfare, the optimization of the dual-card exchanges is getting better and better, maybe there is a day to fight GTX1080

The RX480 8GB chose XFX's Black Wolf evolution, which is more consistent with the overall style.

XFX XFX RX480 4G 256Bit D5 Black Wolf Evolution Graphics OC Seconds gtx1060 3g Bao Shunfeng 1549 yuan Lynx Select Direct Links

RX 480 4GB hardware specifications in addition to memory capacity and RX 480 8GB is the same, not like the GTX 1060 3GB, like a knife from the palace, to retain all 36 units of CU units, 2304 stream processor cores, 256bit memory bit width.

XFX RX 480 4G Black Wolf evolution all black appearance, but the fan can be replaced; graphics length is about 24cm, the basic and the width of the motherboard, the compatibility of the chassis to be more friendly; graphics side of the "XFX" white LOGO belief light The use of 8pin power supply interface, do not be afraid of "stealing the door"; cooling with three 8mm copper catheter, but unfortunately no nickel. In addition, there is a switch near the power supply interface to switch the BIOS (though the defaults of both BIOS defaults are the same).

The back plate is made of anodized aluminum and has an XFX LOGO on it and has some heat vents.

Interfaces: 3 DP and 1 HDMI interfaces, as well as a DVI interface. PCI-E baffle heat dissipation also deliberately made a standard XFX LOGO.

The fan adopts two detachable 90mm fans. The fan power supply uses a contact design. There are two buckles on the fan edge. Pressing the buckle up and pulling it upward can remove the entire fan. It's easy to dismantle and clean the dust by yourself. I directly replaced it with two white fans in order to match the overall style.
In addition, this graphics card also has the function of turning off the fan when the load is low to enhance the mute effect.

After the fans have finished changing, wait for the machine.


The theme is set there, of course, the chassis should be silver, Joe Sibo's aluminum chassis is pretty much, simple design, workmanship is also good, the ultimate goal is to lock in the RM4 and UMX4, compare the RM4's internal space is bigger, feel more For dual graphics, so eventually think the chassis is RM4.

JONSBO RM4 silver ATX chassis (support ATX motherboard / ATX power supply / aluminum shell / 5.0 thickness of tempered glass side panels) 799 yuan JONSBO Qiao Sibo RM4 ATX chassis support ATX motherboard, power is also common ATX power supply. The chassis uses an all-aluminum housing with 5.0 thick tempered glass side panels. Jingdong direct link to encyclopedia JONSBO UMX4 transparent version of the silver in the tower chassis (support ATX motherboard / aluminum shell / ATX power / double-sided 5.0 thickness of tempered glass) 899 yuan both take into account the air-cooled, water-cooled demand Jingdong direct link to encyclopedia

Qiao Sibo RM4 can be said to be RM3's ATX version, simple design, chassis size: 215mm (width) * 445mm (length) * 492mm (high), net weight: 9.5KG, the front panel and the top cover is silver white brushed aluminum, The I/O interface is on the front: USB3.0*2; 1 microphone interface; 1 headphone jack.

The chassis is a single-sided tempered glass side panel. This glass panel is 5mm thick and is fixed on the box with four hand screws. It is darker than the tinted glass. If the light pollution may affect the transparency, the right side board Brushed aluminum plate.

There are eight PCI slots, in fact, it is possible to promote the whole tower, of course, manufacturers do not do so.

There is a row of air intake holes on the front edge of the right side panel. The air intake of the chassis is mainly depended on here. This unilateral air intake design has a slight concern for the air intake.

Above the back there is a fan speed control switch, high and low speed and stop control, can connect three 3Pin fans.

The bottom of the chassis is equipped with open vents and a heat-dissipation network. Four cylindrical support corners are covered with aluminum skin and an annular rubber gasket is embedded.

Remove the side panel:

The RM4's internal space is still very large, especially the front, which can be used to install water-cooled accessories or to install certain E-ATX motherboards. The power supply cover is a removable baffle, which is convenient for the removal of the power cord. At the same time it is also a fan tray and disk tray: support two 14cm or three 12cm (or the same size cold row), or install up to three 2.5 "hard. Heat dissipation in front of two 14cm or two 12cm fan (or the same Specifications: Cold-discharge): Supports a 12cm fan (or cold exhaust of the same specification) at the back. If the air-cooled radiator is installed, the height limit is 170mm.

In addition, this box is not an all-aluminum chassis. The internal blackened steel frame will increase the strength of the cabinet.

The structure of the back of the chassis supports two 3.5" hard drives, and can also be linked to two 2.5" hard drives. The board material is also considered to be a good conscience. I feel pretty good. The steel part of the evaluation of the media is 1.1mm. The front aluminum board is 4mm, other parts of the aluminum plate is about 2mm.

XFX rated 650W XTR650 power supply (80PLUS gold / full module / 5-year warranty / support back line) 679 yuan The XFX XTR series 650W power supply can be regarded as the optimized version of the Rhine G650 program, increasing the low load The fan stopped, the 12cm fan replaced the 13.5cm fan, passed the 80plus gold medal, and the nominal effective conversion rate was 90%. The high conversion rate power supply was a high-tech product. Dual-panel, high-standard materials and LLC+DC-DC topology full-module design, 12V single-circuit design, 12V maximum 54A/6 Jingdong direct link to encyclopedia XFX XFX Element Ti silver plated desktop power module line 8-in-1 set custom power cord 229 yuan Lynx featured direct link

In addition to the graphics card, XFX also produces power. This series of power supply products is a marine OEM, XTR650 is Haiyun G program, Rhine X-650 is also the same program, but the power module interface and the accompanying module The line size and quantity seem to be different. Of course, the price of the XFX XTR650 is definitely lower, and it looks like it is at least 200 cheaper. It is also a five-year warranty.

XFX XFX Element Ti is the official production of silver plated module line, the price is cheaper than their own custom, mainly security is more secure, before there have been friends bought the TB store homemade module line because of the wrong line sequence The whole power boom case.

The power supply is black overall. There are XTR LOGOs on both sides. The topological structure of the Haiyun G scheme is: LLC half-bridge resonance +12V synchronous rectification + DC-DC structure.

The cooling fan is a 13.5cm FDP fan

Power nameplate: The detailed model is XPS-650W-BEF, rated at 650w, in which the +12V single channel reaches 54A, which is 648w, accounting for 99.7% of the total power. Passed the 80PLUS gold certification.

The power supply comes with 10 module lines, in addition to the motherboard power supply line, the other line is a flat wire; and XFX XFX Element Ti of course is a higher value silver plated wire.

The XTR650 also has a fan-quiet technology called “Hybird Fan Control,” which automatically controls the fan speed according to the load and heat of the power supply. Fans are stopped at 20% load or within 25 degrees. However, the switch of this function is placed on the module line. If it is installed, it is difficult to press the switch.

There are 10 module output interfaces, and the main board power supply line occupies 2 interfaces. The 18+10 interface is the same as Haiyun itself. The module line can also be mixed. IDE/SATA output has 4 power supply ports, and CPU/ The PCI-E output also has 4 output ports.


Radiator is Kyushu Captain series 240, white models.

Kyushu Fengshen (DEEPCOOL) Captain 240 (White) CPU Radiator (Multi-Platform/Lighting Breathing Lamp/Double 12CM Intelligent Temperature Control Fan/Pre-coated Grease/Mute) 899 yuan Jingdong direct link

The cold head adopts an external design of glass water pipes, which really adds bonus points. The base of the radiator is pure copper, and the internal micro-channel uses a 0.2mm process.

However, the fan is used Qiao Sibo D FR-301P-white glare, 12CM fan, 4Pin temperature control fan. The lighting effect is 3 bars and it is still very special.

[Host Effect]


The cold exhaust fan has been changed to the "Hamburger" type, and the wind direction is the air intake. While increasing the cooling effect of the CPU, it also brings more air volume inside the chassis. After all, it is a double card inside the chassis, and more cold winds are beneficial.

Topline effect.

Successfully lit, two 14cm blue electroplated fans were added at the bottom of the chassis. At the same time, dust-proof nets were added. It was not for dust protection. The main bottom line was relatively large and it was easy to touch the fan blades.

The overall light pollution effect is still very harmonious.

Added effect of "Gintama" element

Effect inside the host

The side panel glass is relatively dark, and even if the brightness is very high, the light pollution will be darkened a lot after closing, and there is an effect of lightening the light pollution.

[Overclocking attempt]


Now ASRock's bios are more concise, unlike the previous generations of cartoon styles, click advanced mode to enter more detailed settings.

Overclocking first set a small target: 5GHz bar, BIOS voltage is set to 1.4v, basically stable, but for security or added 0.1v, is the final voltage of 1.41v, perhaps my body is not very good constitution.

Run several regular CPU test projects:

International chess

Commonly used running software, the test is multi-core performance, but this product is not sensitive to the new instruction set, resulting in new U and old U out of the same score.

CINEBENCH R15

The test is also multi-threaded performance

The basic frequency is increased by more than 10%; performance is also increased by more than 10%, and it is linear.

[Crossfire test]


XFX this card crossfire, do not load a heavy load, the second graphics card is not working, graphics and fan LED are not bright, you can save some electricity.

Under the condition that the CPU frequency is 5 GHz, the comparison of running cards for single card and dual card is done.

3Dmark11

3Dmark


Do a summary analysis of the data, low-resolution test score is not high, such as 3DMARK11 P-point efficiency is only 40%; Fire Strike's crossfire efficiency is only 60%, high-load test efficiency can be about 80% . The efficiency of crossfire in graphics scores is basically above 90%.

Of course, 3DMARK test crossfire efficiency has always been more efficient, the following in the next game to measure some of the game, the first is 1080p conditions.

Again to challenge the next 2k resolution.

Killer 5, bloody rogue, ancient tomb 9 and subway games, CF efficiency is basically 90%, very efficient; two DX12 games, the efficiency of about 70 to 80%, is also acceptable; but Wizards 3 and gatekeepers Dog 2's efficiency is only 50 to 60%. In addition, the overall efficiency of crossfire under 2K resolution is slightly higher than that under 1080p.

There are a lot of people who should say that 4G is still a problem. In fact, the principle of SSAA anti-aliasing is to compress the entire image with a higher resolution image to a low resolution image, which consumes a lot of graphics resources. The resolution of the screen under high resolution is inherently high and does not require too high anti-aliasing. Therefore, high-resolution, it is recommended to use anti-aliasing such as MSAA, this type is only to soften the edge of more deformation, rather than the entire screen, so the resource consumption is much smaller.

Therefore, as long as the proper adjustment, in most cases you can avoid the explosion of memory problems. The above few game settings did not show any significant problems.

There are still some practical problems with dual cards, such as heat dissipation problems; the dual card optimization of new games is not good, the efficiency is low, and the energy consumption is high. If it is an average user, after installing the host does not want to toss again, it is recommended a single card, more worry; if you like tossing, like to try various hardware and software settings, dual card or some interesting gameplay. Of course, there are still some people who believe that there will be more games to support dual card exchanges in the future. .

[Closed]


Host installed, infuse the elements of Gintama, completed their own little feelings; small overclocked CPU, looks a little better than Skylake a little bit, but the temperature is still not optimistic; after many years, willful play dual cards, crossfire, Try various settings, various tests.

In short, it's a good time to be busy and the result is not bad. The process is also a kind of enjoyment. This is the joy of PC DIY.
