SLI causing hard freeze?

post #1 of 10
Thread Starter 
Hello everyone. I've recently bought another gtx 560 ti for my computer and so i had to change my motherboard too since the old one didn't support SLI. Well first of all i haven't noticed about any increase in performance when playing games (not too many atm) or when running msi kombustor benchmark. Secondly when playing BF3 with SLI enabled it runs horribly... it's worse than with just 1 card and after 5-15 minutes of gameplay the whole computer freezes and i'm forced to restart. At first i thought it was only BF3 but then it happened with Left 4 Dead 2 (after about 1 hour of gameplay). I didn't find any answer to this problem except people just telling to re-install GPU drivers but i have done this many times and have tried the newest BETA drivers and also the latest WHQL driver. Everything works normally when SLI is disabled so i don't suppose it's the new motherboard which is a P8P67- EVO. So does anyone have any idea what might be causing this bad performance and freezing? Any help is appreciated... thanks.

specs:

i5 2500k
2x 4gb kingston hyperX 1600mhz RAM
2x msi twin frozr gtx 560 ti 1gb in SLI
Asus p8p67 evo
Corsair GS800w psu

I'll ask the two obvious questions - what PSU do you have, and have you put the sli bridge on? biggrin.gif

Have you tried resitting the 2nd GPU and checking if it's being detected?

well i can see both of them in the nvidia control panel so i guess they're detected? and oh, instead of msi kombustor i tried furmark this time and i did get a better score with SLI enabled. but still, this freezing worries me. gotta try some more games and see if i get a difference in performance...
post #6 of 10
Thread Starter 
when SLI is enabled the FPS is almost 2 times better than with just one card in games like Skyrim, Killing Floor and Left 4 dead 2 but i get this weird stuttering when moving my mouse that doesn't show up in the FPS. what could be causing this? and also BF3 was still unplayable. Also when running SLI the 1st GPU gets WAY hotter than when using only 1 card. Could the problem be with my motherboard? How could i test if my motherboard is defective? ps. the new mobo (p8p67 EVO) has a slight delay when booting the pc. It's only like 1 second but still I didn't have this kinda thing on my previous boards. Could this be something to think about?

Same thing happens to me with SLI gtx460's. My computer completely freezes with BF3 and Skyrim. I've ask around and no one seems to know the problem. I got sick of it and just went with single 570.

The top card will always get hotter! Think about it! I'm sure you'll work out why thumb.gif

Are you using a wireless mouse? If so, try lowering the poll rate!
And make sure your mouse and keyboard are plugged in the USB 2.0 ports! Not the USB 3.0 ports smile.gif

Hi Edisoni. May be obvious but install each card alone to see how they behave. Might just be one of them giving you problems.

I decided to play it safe and returned the other card while I still could. Didn't wanna get stuck with a POSSIBLY defective card so... Anyway, I'm still eager to know what was causing this if someone might have an idea, but the bad thing is I'm unable to tinker with the SLI at the moment so I can't test it anymore. Basically this isn't my main concern anymore so no one has to go extremes trying to solve this.

Thanks to everyone who replied. And I'm still hoping for suggestion on what might have been the problem.
