HIS 7950 OC problem

[Gloremir]

Hey peepz.

Kinda need some help from you.

Im running a HIS 7950 with Arctic Cooling Accelero Xtreme cooling.

I have it 100% stable at 1150/1575 and 1.175V
Stable in every test you can find.

But when i turn it to 1200/1575 and V range from 1.175 - 1.225 (havent dared to go over it)
its stable in every test BUT not heaven. im satisfyed with the clock as it is. but surley i wanna c if it can hit 1200 in heaven allso.

any ideas?

thanks in advance

More volts or it just wont do it.

BTW a clock is stable when its GAME stable or 3d Mark Vantage stable.....

Strange that it's stable with everything else but Heaven. I can get Heaven stable on lower volts than any other game or bench.

All comes down to the silicone lottery though and what your card is capable of though, no two cards are the same.

Well how high do u think i can go in volts? well BF3, Farcry 3, Assassins creed 3 are all stable. so is 3dmark vantage and 11.

im happy with the clock anyway. more then i could imagen with the cheapest of the 7950 cards on the market here in sweden.

seems like the next upgrade will be to change to intel. according to different grafs my CPU is bottlenecking the rig.

beacuse i cant get this 965 to go over 4ghz

Only you can tell mate, every card is different.

I am having huge issues with my sapphire 3870x2. I tried everything. It has to be able to overclock just a little bit. I tried overvolting it from the bios, it made it even more unstable, it would crash the first second I would turn on furmark... sometimes it would last but my pc would just shut down without any warning, I mean dead stop. I had to turn the PSU switch off for a few secs to be able to turn it on again. Strange thing is that in 3dmark vantage I sometimes get a bluescreen with a video tdr failure message. It's crazy!
