And i hear a very irritating noise from the card, maybe thats the famous coil whine. Is this all driver related? (except coil whine ofc) Its a reference Sapphire board, on stock clocks.

Only way to be sure is to try some other drivers. Try RC11 in the OP, or some of the beta drivers. Is this a clean windows install btw?

RC11 crashed Java when i entered Minecraft.
I installed 12.5 beta, ran Heaven, its the same thing. Also something else, i've noticed this only in Heaven - sometimes everything freezes for 1+ seconds, in the same time the coil whine stops. Then everything is back to normal. It feels like the card turns itself off headscratch.gif

And its not clean install, i've had this windows for a few months, i was with 8800GT till today, but i did clean the drivers with Driver Sweeper.

Well I wasn't having crashes, but I was getting a lot of artifacts after I replaced my 560ti with this. Driver Sweeper and Atiman only made it a little better, but still problems. Honestly it's the biggest pain in the @#$ but my recommendation is to reinstall windows, and if you still have problems RMA that thing. The stop/freezes are a bit worrisome especially having the coil whine stop. Mine jumps in 3D11 Graphics Test 3 a bit, usually near the end where it gets close to the pillar, but the Coil Whine never stops and in nothing else do I get that.

I've looked everywhere I can for s solution and reading through this thread it appears xfire users have well over 120fps. Also using 12.4 drivers with the latest CAP

Had a similar issue. What I did was Alt+Tab in game and then dis a small volt tweak up or down with AB . When I return to game get 98-99% usage on both. Latest beta driver does away with that for me.

Hey guys! I was wondering the best way to test an overclock for stability on my new 7950. I am currently using AB and running Heaven and 3D11. I will run OCCT for like 15-20 min if stable in 3D mark and heaven, just to check max temps. Would you guys recommend a different methodology or will this work. I also run BOINC so I need an extremely stable overclock or some work units will get errors.

I am going for a good ratio between Voltage/Temp/Performance on my 7950. I would like to be right around stock 7970 performance. Also, what settings is everyone using in Heaven so I can compare some results.

Thanks!

I used MSI Kombuster to test stability, I've been told if it handles the stress test for about 5-7 mins without screen flickers then its good to go, just make sure that you have the fan speed cranked up, temps sky rocket. lol

BF3 will stress your OC the best imo. I posted this a couple pages back, but on my card, OC was stable in Kombustor and Crysis 2, but I'd crash in BF3 MP. Wish BF3 had a built-in benchmark. It sucks seeing a black screen-CTD when you're having a good game.

Some of you guys have some really nice cards. My ASIC Quality is around 68%.
Using Trixx with voltage @ 1.36v...I can only get 1275 core and 1500 mem... and this is on Water!
31c idle and 39-44c load!!!!!!!!!!!! ugh...I need more volts! smile.gif

prices for the 7970 and 7950 came down a lot

both of my cards have very good ASIC, but that doesn't mean much when they crashes for like no good reason, all due the weak drivers.... sigh.. frown.gif



So, i was reading over on the ASUS ROG forum, it seems like the 7970 crashes might be due the PCIe Gen3 issue
by default the cards are detected as PCIe Gen3
but some people having similar problems as many of us owners of 7970 are having, they reported the card to run more stable when forcing the BIOS to run the PCIe slots to run as Gen2

i'm gonna try that when i get home to see if i can finally play a full game without crashing on me at random times

I haven't discovered a limit to voltage on my 7950s. I took them to the max of AB's slider, 1.299V and had no issue. The only voltage I saw from them was 0.993V stock.

Also, for anyone concerned about ruining your cards. They have protection features in place that will shutdown your computer if they are approaching an unsafe temp. I had some 3850s (x4, yeah, legit quad fire, lol) back in the day that would get to 115C before killing the comp, but no damage was ever done. Just my 2cents.gif
