Crossfire/driver issues with my 7970s

post #1 of 25
Thread Starter 
I've had these cards since the 12th and have just recently started having or started noticing this issue. I first noticed it while playing Skyrim about two days ago. I wanted to compare crossfire with single card performance and re-enabled crossfire after playing on one card. When I looked over at my bench I saw the fan standing still and freaked out, shut things down and noticed changing from crossfire causes issues. I had been playing SWTOR recently in both crossfire and single card with no problems.

It seems that now, when either enabling or disabling crossfire, the fan on card #2 spins down and stops. It spins back up again when re-enabling or re-disabling crossfire (whichever state it was in originally). I've also noticed that when this happens MSI afterburner stops function correctly, stops controlling fan, stops reading temps, consumption, etc of card #2. I'm assuming this is all driver related (running 11.12 or whatever the only version is, released on the 9th I think.) and will be worked out.

I'm not stressing the cards until I can get them under water and control the cooling myself, but am wondering if anyone else has had these issues or recommends some other things to try to diagnose the problem further.

I haven't poked around yet so apologies if this is a known problem.

When you change configuration from 1 to 2 or 2 to 1 cards, Afterburner can not do that on the fly. Best is, reset Afterburner, restart PC and it will take the changes correctly.

thanks for the tip. my main worry is having the fan stop spinning under stress. had the card not been on my test bench right next to me and inside of my case I'd have been running it with no cooling and never known it.

I'll just have to deal with constant restarting for now.

its not a driver issue, its supposed to do that in order to reduce noise and energy consumption, CFX it and then put it under a load and it will spin up again, when ur in CFX and your idling honestly a 22nm GPU will not output much heat at all

FWIW there is a new driver out that AMD recommends all gamers to install.

That makes complete sense, but what alarmed me is that that behavior (stopped fan at idle) just started happening; before, I had always seen the fan running. I'll double check, but I'm pretty sure when I stressed the card, the stopped fan didn't spin up like it should. When it happened, my personal core temp shot up so I may have not been thinking clearly myself as I tend to assume the worst^^

thanks, I'd been checking the AMD site religiously and thought I'd had the latest. I'll test that out tonight.

cheers

NO luck installing either 12.1 or 12.1a previews.

I'm stuck with 11.12 for now.
