[SLI] Double 1070 scratch

Hello everyone~This is Guoguo Meow!

I hold a noble ROG 1070-o8g video card (hereinafter referred to as "three fans")

During this time, I paid a piece of bad 1070-o8g (called "two fans" below) from Leng Wang

The parameters are compared. The gap is not big... maybe the gap is not bad after using it for more than 3 years. His piece had been used for less than three years, and it had been hung with - V. The following figure shows the three dimensions of the 2 video card

The picture on the left shows three fans, and the picture on the right shows two fans.

Two front and back ID photos of the video card. When taking ID photos, you can clearly feel the difference in the "weight" of the two graphics cards, which is the weight of money! As well as the fully plugged chassis (yes. 3 The fan graphics card may have been "bent".)

Start tossing!

The card has returned after more than 10 days of insurance. And Guoguo also tried some experience in playing dual graphics cards and wrote this article to record it.

WIN10 system. Z170-A motherboard, the driver of the first graphics card has been installed normally. After inserting the second video card, install the SLI bridge supplied with the motherboard. Restart 1 second after the mainboard is powered on. Meow thinks that the mainboard detects that a device is inserted in the second PCI-E channel. The speed of rebooting and adjusting 2 lines is X8.

After power on. The system prompts that the second graphics card needs to be reinstalled. After a few minutes of waiting. The system has automatically installed the driver and adjusted it to SLI mode. Very stupid!

After setting up the SLI, I first tried the game of Watch Pioneer. It can be seen from the figure of the GPU in the task manager that it is supported

Almost the same 2 charts. Then each graphics card has less than half of the occupancy rate

Next, we tested several small games, such as Dawn Killer, Warship World, and we can clearly feel that they do not support SLI..

The drought of drought dies, and the waterlogging of waterlogging dies... At this time, the load of GPU1 should be that part of the GPU calculation in the web browser or game is allocated to GPU1.

Game related summary

In general game situations. The two graphics cards that cannot run with one video card may not be different. The CPU load becomes significantly higher at 144fps. On the contrary, it may cause some strange visual problems due to SLI's BUG (once encountered in the Watch Pioneer) [the highest picture quality in the watch is dizzy because the picture is too gorgeous]

There are few 3A masterpieces. You can test it when you have time. But I have heard that two 1070 runs are similar to 1080 before. Why not use 1080 directly? (It should be 2080 now. The gap is even bigger.)

Dual screen

Now that we have set up a dual video card, we need to test the dual screen.

SLI mode. Only when all monitors are connected to one video card can they be used. If two video cards are connected, SLI cannot be enabled (but it seems that if surround is enabled, multiple video cards can output without testing)

There is no difference between dual screen output and single video card~too

Drama! Dual GPU live broadcast

okay. It's the most interesting part for Meow.

The following topics are all about the game "Watch Pioneer". Because the Blizzard products must be exquisite! Ha ha ha ha ha ha ha

Some unsatisfied parameters were not listed. Say the result directly

The first test content is:

Enable SLI. Watch Pioneer has high image quality, and OBS video card coding has the highest quality preset. 6K code rate, 1080x60fps.

——The load of dual GPUs is almost the same. Every 10 seconds or more in the game, I feel that the FPS has a 1 second drop of BUG. give up

Turn off SLI, and watch the vanguard in the picture quality. OBS video card coding highest quality preset. 6K code rate, 1080x60fps. And set the video card without display for coding

——The GPU output of the inserted display is 80%, and the other card code is 10%. The live broadcast is smooth (poor picture quality). Smooth operation in the game

Single graphics card. Watch Pioneer has low image quality, and OBS video card coding has the highest quality preset. 6K code rate, 1080x60fps.

——The live broadcast is smooth (poor picture quality). The operation in the game is smooth... there are some wrong appearances... (If the image quality is in the middle, you can feel the operation is delayed.)

summary

SLI technology is an outdated technology at present. Will disappear in the extinction of history.

But I never thought that my dual GPU achievement was earlier than the dual CPU achievement

Next, Meow just needs to collect another E5 2680V2 to achieve dual CPU achievement~

(Next, we can try to achieve: 10 gigabit network...... 24 memory lines are full of 384G memory......)

Supplement: expensive ones may not be low in noise. It's not necessarily that the temperature is low when the load is high... I feel it is almost the same... when the load is lost. The expensive temperature comes down immediately. But the cheaper ones need to be blown for a long time...

Pick up the guy and run away... Throw away some waste drawings
