Computer turns off while running 3D Mark Vantage 7970 xfire

post #1 of 27
Thread Starter 
Hey guys I got my 2nd 7970 today, so i installed the waterblocks on them and installed them on the computer. I overclocked them to 1100/1500 @ 1.175v using TriXX. So i run the bench and when the 2nd test tries to load my computer turns off. I set GPUz to create a log file so i could check the temps, and they did not go over 52c. I'm thinking it's my power supply, but it's 1K watts, but I've had it for a few year though. When I ran these test with a single 7970 my computer did not turn off at all. I could even push the card to 1200/1800@ 1.2v and no shutdown, completely stable. Any thoughts?

is your cpu overheating at all this could also cause it?

Good call on trying again with one card rather than two. If you were able to run the benchmark with one card successfully rather than two, and your rig shuts off with two, then it sounds like a PSU issue to me, yes. Either that, or the specific benchmark you're trying to use is buggy for CF configurations.

Have you tried any other benchmarks, or maybe even games?

sounds like an unstable gpu oc to me.. i would HIGHLY doubt it was the psu. try running them at 1.2v 1000mhz and lower the mem clock and run it. That would eliminate the psu as an issue.

ok cool thanks i will try lower mem clock speeds, and see what happens. My Cpu is liquid cooled as well so I know it's not overheating, I have it running Seti@home all night using all 8 cores @ 100% and it doesn't even get to 60c

Yeah that reeks of potential PSU problems. But a 1000w PSU should be plenty for a pair of 7970's since they've only got a TDP of 210 watts. Even an heavily OC'ed FX-8150 or a Gulftown i7 wouldn't eat up the remaining 600 ish watts.

What kind of PSU is it?

doesnt sound like a psu issue to me at all... as someone who has spent a LOT of time benching this sounds like an oc issue to me.

ok the bech runs all the way through without shutting down without an overclock with a score of 17853. I'm gonna try a core of 1000 and mem of 1375 and see what happens
