HELP! Low FPS with dual SLI 670's

Sandrop · Apr 8, 2014

My FULL system specs:
PSU: Thermaltake Smart 750W Bronze
Ram: 2x 4GB Corsair Vengeance
MOBO: Asrock z77 Extreme 4-M (mATX)
HDD/SSD: OCZ Agility 60GB/ Western digital 1TB Caviar Blue
CPU: intel core i5 3570k (stock clocks @ 3.4Ghz)
GPU: GIGABYTE GTX 670 OC EDITION 2GB/ EVGA FTW GTX670 2GB
1920x1080 Resolution Acer Monitor @ 60Hz

[strike]Edit: these were my results on Windows 7 taken from MSI Afterburner;

[strike]I've tried reinstalling the drivers and changing the 'parking' with windows 7, but no luck.
I get better FPS with 1 670... [/strike]

EDIT: This problem is now fixed! Windows 8.1 Fixed it along with the new Nvidia drivers! ( I recommend anyone with my problem to install Windows 8 Immediately! (thank you to everyone who helped)

What resolution are you playing at? Your cpu is probably getting maxed out (regardless of what anyone else says I see my 3570k get all 4 cores maxed out with 7870 CF). Open task manager>performance to see cpu and RAM usage. Use MSI afterburner to see gpu 1 and gpu 2 usage. While in game watch those graphs. What is gpu 1, 2, gpu memory, cpu core (ignore average usage) usage, and RAM usage?

Did you try firemark or another benchmark?

You will need to provide more information, using MSI Afterburner or EVGA Precision check what the GPU usage is on each card and post results.

Sandrop · Apr 8, 2014

alright, im playing bf4 on medium and its running pretty choppy, i'll post results soon.

Sandrop · Apr 8, 2014

Edit: CPU usage is at 92% in Task manager
CARD 1
GPU-Z Current temp is 43c
with a GPU load of 40-45% average 53% Max
Core Clock 979.8 Mhz
memory clock 1502.3 Mhz

CARD 2:
Core clock 1006.6Mhz
memory clock
1552.5 Mhz
Temp 50c
memory used 1121MB
GPu load 34%

Edit 2: would it be easier if i used MSI afterburner instead of GPU-Z?
also im experiencing some high microstuttering..

You might have some of your cores disabled make sure turbo boost is enabled and that a 4 cores are active you can do this in the extreme tuning program, or you can type msconfig go into the boot options then click on the cores box to check it, and then set your cores to 4. Then reboot

Hi, thanks for the reply I tried doing it in msconfig, but I dont know what you mean by the cores box to check it?
I go to the boot tab, then advanced?

lfkfkfkffs · Apr 8, 2014

In the advanced boot options tab click on the first fox in the upper left corner and then select 4 for total cores then reboot

Try playing a game

Sandrop · Apr 8, 2014

lfkfkfkffs :

BF4 Medium 70 FPs Average, Min 56 Max 113

lfkfkfkffs · Apr 8, 2014

So did it help at all?

Sandrop · Apr 8, 2014

lfkfkfkffs :

I tried playing on ultra and no success, even high is laggy. Even with a single 670 i got better results, I can't work out what it could be. It's just straight up horrible performance, I don't know what to do...

lfkfkfkffs · Apr 8, 2014

Most likly poor driver support for that game in sli for you cards. I think the next step would be is to call the card manufacturer and see if they know of anything. It could be your power supply but i doubt it

Sandrop · Apr 8, 2014

lfkfkfkffs :

I read on other forums people with similar SLI configs are saying as soon as they went to windows 8 all the problems went away? I don't understand how this even makes any type of sense? I previously had Windows 8 before SLI'ing today.

lfkfkfkffs · Apr 8, 2014

If you have the disk and everything go ahead and try it on windows 8 that would be my next step

Sandrop · Apr 8, 2014

lfkfkfkffs :

I don't anymore... I'll have to re-buy it. It's used on the other computer.

wanderer11 · Apr 8, 2014

You said 92% average cpu usage. I'm about 99% sure that means one of your cores are maxed out. Do it again but only look at the core usage graphs. If you see one core maxed out then it's a cpu bottleneck.

lfkfkfkffs · Apr 8, 2014

If you have the disk you can install it without activating it just to see if it helps

Sandrop · Apr 8, 2014

wanderer11 :

How do i check each core individually
Edit: I ran single player and I was still getting awful results, is this a bottleneck or something else?

Ah I dont I only have the beta which is unstable..
