Sapphire Vapor x 7950 overclocking and voltage

I can post my results in another thread. This thread was more to show whether the Vapor X is voltage locked or not. Which it doesn't seem to be, you just need the latest version of Trixx. Would be great if some other people could confirm this though. I had a feeling that the card wouldn't be voltage locked and that it was just a issue with the new boost feature or something.

I'll run the benchmarks this evening with those settings mentioned. Thanks

If you are only hitting 57 degrees at full load you have a fair bit of headroom left with your voltage. Im pretty sure you could reach 1200MHz on your core if you are willing to give it some more voltage, which would give you overclocked 670 performance.

Try 1.2v and see if you can bench at 1150MHz, and take a note of your max temperature. Also put tesselation on normal for heaven please, it allows us to compare scores more directly to other people. Thanks.

That wasn't stress testing :) I was just running the GPU-z render program. My temps were definitely a lot higher when I was running heaven but I didn't check them.
 
Been playing around with the volts and core clock.

I've found going above 1.1vddc makes my VRM temps too high for prolonged use. ie. 90c +!! I think that's down to poor design. The GPU itself sits happily in the high 60s to 70c whilst stress testing.

I can get a core of 1150mhz stable but I need about 1.13vddc and the vrm temp scares me. I think for general use 1100mhz will be fine at 1.1volts. I could run heaven at the higher clock but I'm not interested in getting big numbers for the sake of it...

btw the fan at full speed is insanely loud... I have no point of reference as it's my first gpu in about 10 years. Below 40% speed and it's fairly quiet.

Don't worry I got my msi tf3 today and when oc fans can be insanely loud when on load. But that doesn't bother me at all as I got my headsets on:D I had a little test with the oc and managed to get it stable 1150 / 1500 with 1.16 vddc with Temps being 70 c max in stress testing. I reckon I can improve those results with more time with it as i only played with it for an hour or so.

It's a shame that the vapor x's VRM get so damn hot as I was stable at lower volts with the same clocks. What's your VRM temp on that?

I'm not on the pc now so I will check that tomorrow and let you know. But you mention your Temps high 60/70s on stress. Is that with you having 1150 MHz and 1.13 volts?

Updated my first post. I've found using the boost bios is more efficient with volts, temps and clocks. Also lowering the memory speed a bit really helps vrm temps without affecting performance much. 1350mhz seemed to be the sweet spot for me.

Thanks for getting back. Iv been testing too and iv settled for 1150/1400 @ 1137 voltage and all temps are under 70c. [Il try 1200 when i get time]. The interesting thing i noticed is that before i had my top exhaust fan on low and temps were rising to 78c in game which caused artifacts. By putting the exhaust fan on medium temps went down to 69/70c in game and no more artifacts :D
 
Has anyone else tried out the V09 and V0A bios update?

Gave it a go and my VRM temps dropped loads but my overclock wasn't as stable and couldnt really overclock the memory at all, I think because the mem voltage is only at 1.5 (couldnt raise this through AB :().

Not tried them. Haven't needed to as it handles everything fine for me.

I did read about there being different versions of the card which would need different bios'
