Gigabyte GTX 670 SLI causing Slow FPS

MYSRH · 7th August 2012, 12:12 AM

I installed 2xGigabyte 670GTX in SLI on two 22" Samsung monitors. When I play games, I experience a very slow frame rates or choppy frame rates on games Battlefield Bad COmpany 2, Diablo 3, and Battlefield 3.
It plays normal FPS when I use one card only.

Is there something I didn't configure correctly?

Are you 100% the cards are setup correctly? Latest drivers? SLI bridge? Correct PCI slots etc?

What PSU do you have?

System specs?

a couple of friends of mine had the same problem when running sli with 2 gtx670's, the only way that we found to completely eliminate the problem is to go for one the alpha drivers, there is something bugged in the official Nvidia drivers about those cards and sli.

No problems with mine...installed and within minutes all running perfectly.

Yeah when I had 670's they ran fine aswell..

Specs are:
Windows 7 Home 64
Intel 3770K
Mobo ASUS Z77 Sabretooth
16 Gb RAM
PSU: Corsair 850W

I did drivers sweep and installed latest drivers from NVDIA. The system was built from scratch.
Windows recognises both cards, I can select to enable/disable SLI, which is when it's enabled the option says somthing like 'maximise' 3D...

Well the only technical hardware related stuff I think is possible is that either something is wrong with your SLI bridge or something is wrong with your PSU. It is more likely though it is software related - tried the beta drivers? If using the beta drivers tried the non-beta drivers?

Thanks, Rave.
I'll try with different SLI bridge, IF I have any laying around.
How do I check PSU? Bought new, it's running good so far.
I'll also intall the beta-driver tonight

I wouldn't worry too much about the PSU if it is new. The Corsair PSUs are pretty good. They are hard to test anyway - you would need a multimeter to do it right. I only originally asked about the PSU in case you were trying to SLI these on 500w or something. Your PSU should be fine. Of course, I guess there is the slim chance that something is wrong with it and it isn't delivering the power the GPUs need.

Now I think about it though you could do a very inaccurate style of PSU test by disabling SLI, plugging a monitor into one GPU and another monitor into the other GPU and run two instances of a GPU benching program, one on each screen and see what happens.

I would just update to the latest beta drivers before I do anything though. They do have some SLI updates for some games. I have been using the beta drivers on my non-sli setup and I haven't had any problems with them.

Which bench test I should use? I may test on the current setup with current drive, see what results it gives

I would use heaven - it's free. Set it all to max and remember to press F9 once you load in to start the benching.
