Crossfire XFX 7950s crash after ~5 minutes of full load

FusedZero · Sep 18, 2013

I purchased a second 7950 last week and installed it last night. I've been having issues with it ever since I started. I updated to the newest drivers last night, but I still crash quickly. Eventually I tried the beta driver and ironically seemed to have more success, but it still crashes after about 7 minutes. I benchmarked them with Heaven today and it made it all the way though with a 1787 for the score. I figured I was in the clear from there, but evidently not. I tried to play Crysis 3 on max a little while ago and played for about 10 minutes before it froze my whole computer. I also tried changing the crossfire bridge which didn't help at all. I'm out of ideas. Please tell me anything that you may think will fix this problem.

could it be that the card is faulty? Contact tech support from the company you bought it and get it replaced. That's my best guess.

ajchavez91 :

I could try running the card alone for a while to check

Eximo · Sep 18, 2013

Temperature?

Also try re-seating it in the slot, sometimes the unused slot gets filled with tiny dust particles that make for intermittent connections.

FusedZero :

that'd be ideal. Better to check if it works while being the only one installed. If it still crashes, you should take it to the store and get a replacement. Also, this is very rare, but it could be the pci-e slot that is faulty. Try running it for a while on both slots (the one where the good card is, and then the other one).

Also, Eximo could be right, re-seat and check the temperature while playing. MSI Afterburner is a good option for that.

what power supply do you have? maybe not enough power. id say a good quality 750w psu would be the go.

Onus · Sep 18, 2013

What is the brand and model (not just wattage) of your PSU? A PSU that is being stressed may wander out of spec, causing crashes. Is the PSU fan really loud trying to keep it cool?

FusedZero · Sep 18, 2013

Onus :

Not making excessive noise or any for that matter. It's a Thermaltake TR2 RX 750W.

FusedZero · Sep 18, 2013

Eximo :

I'm not even passing 75c on full load and I'm going to try reseating right now.

Onus · Sep 18, 2013

Is it an older TR2? Does it have a little voltage switch on it? The TR2 RX series was made by HEC, which does not enjoy a good reputation for PSUs. It is undoubtedly overrated, and probably cannot handle those two cards.
You'll either need to go back to one card, or get a better PSU such as a Seasonic or Antec.

FusedZero · Sep 18, 2013

Onus :

No it does not have a switch and I think it's about 2 years old

What kind of freeze? Blackscreen? Freeze on current screen? Freeze w/soundloop?

Try using an older cable, like DVI or earlier HDMIs.

Also it could be a power supply problem, try it with a friends, if possible. Or just buy a new one, good brands are XFX, Corsair, and Seasonic.

darkspartenwarrior :

It freezes on the current frame and just stays there until I manually turn of the computer. It's not the cable because if I'm on skype when it happens, all sound from skype is gone. So the whole computer just locks up when it happens.

I just completely removed all AMD and ATI drivers then installed the new 13.9 driver, but to no avail.

Onus · Sep 19, 2013

Did you test your RAM? What if you only use one card? If the RAM tests good, this is looking more like a power problem.

FusedZero · Sep 19, 2013

Onus :

There are no issues when only running one of the cards. I tested both individually. I may not have removed the drivers correctly from before. I was using a somewhat old forum post. If you know how to completely remove the amd drivers and reinstall them or know a good link to a guide for the process please tell me.

Don't know if this matters or not but I found this (screenshots): http://gyazo.com/6adc2e6847e38f3c147008c3389fccc4

It says that one is 16x and one is 8x.
I was reading somewhere else that if it's not 16x it's not giving the card as much power.

Here are some other screen shots from GPU-Z. I noticed that the bios were different. Not sure if that means anything.

the tr2 RX series are notably bad. the newer 80plus certified ones are ok, but not the best. I would say get a proper psu by antec, corsair or seasonic.

FusedZero · Sep 20, 2013

Just ran the new card for about an hour an a half and it crashed alone. Sending it back for a replacement.

ajchavez91 · Sep 20, 2013

FusedZero :

Perfect. At least now you know it's not your PC's fault.

FusedZero · Oct 4, 2013

Just got my new card, but still freezing. I'm not sure if it's my power supply because when I ran the first one alone, it still froze. If I haven't already said this, I am trying to run my original xfx 7950 (The longer version that came first) and the new xfx 7950 (The shorter version that came second). Could it be a software problem? They both have the 13.9 driver and I uninstalled the drivers completely before installing the new ones. I'm going to Fry's tomorrow to see if they can give any insight and also if they'll let me buy a power supply and see if it works. Please tell me anything that you think might be wrong.

FusedZero · Oct 8, 2013

After a trip to Fry's and buying a new 900w PSU, It works great. Thanks to all that helped.
