1.33v to Dice/nl2 hmm
5/6XXX serie I use 1,45v on air an from 1.45 to 1.55v whit watercooling

I test a 5XXX serie here on air whit 1.56v

Awesome mate, is it a modded tweaker or will the stocker work? Any 3d11 and Vantage runs yet ?

Its the same tweaker, just a different bios. Havent run 11 or Vantage yet, will try this week.

I would think afterburner, trixx or gpu tweak set the maximum voltage at 1.3 to prevent the average user from cooking the gpu. People will try run 24/7 with high voltage, and end up crying because the card died.

I pushed the 5870, and 4890 pretty high on vgpu also, but for quick benchmarks, not for hours of gaming.

Can anyone confirm that heatsink removal voids warranty and if manufacturer will be able to tell? Eg phase change TiM removed or disturbed?

Cheers

[OC Nub]

They will be able to tell, read something about the way they applied the thermal paste could not be duplicated. Not sure about voiding warranty, guess it would depend on manufacturer.

[tbone8ty]

cool that they use good TIM now and not spluuged on like gtx480's

Perhaps you can go old school and use Rivatuner to select a nominal voltage higher than 1.27v for the 7970. When programmable VRM's started showing up on graphics cards, we started some topics along the lines of "there should be a software with a slider bar to control voltage on a graphics card". Now 3 years later, software all over the place! haha.

About the bios you posted, you flashed it in to your ASUS card ( I've an asus card too ) and the you were able to set higher voltages then 1.3v with software ? Or it will let ASUS GPU tweak it go higher then 1.3v ? Thanks for the help

The bios allows you to increase the voltage using gpu tweak. It is not a set voltage, just gives the option to raise it above 1.3v. You can run at default voltage if you want.

I was stuck at 1295 maximum core clock, but I found this bios at another forums, KP Cooling forums and gave it a shot.

I would not try this with stock cooling, water minimum. If anyone kills the card trying this, its on you. I got the card for benching, and at 1295 I wasnt getting far.

I'm at WC so no problem on that side. I also read KP Cooling, I would like to ask you witch version of GPU tweak you use ( to go above CCC ).

[OC Nub]

Im using the one from the link in the first post here in this thread, it also has ati-winflash in the folder once you install gpu tweak. I was lazy and used ati-winflash, figure it has dual bios so no problem fixing a bad flash. All went well though.


Second screen shows the limits once you check the box for overclocking range enhancement.

Strange. I'm using the GPU tweak from ASUS web site, idk if it's equal to that one or not, when I slect that the screen flickers etc but nothing changes...

Thanks for the help anyway

Wow, what a waste of money. Unless all you do is bench 3dmark11. Sorry but its the truth, AMD's multi GPU is terrible.

[Astennu]

My card hits 1125-1725 air auto fan speeds. IF the temps get to 85c+ i get artifacts on 1125. (only happens with fixed fan speeds on 30%)

The Same is true for Quad or Triple SLi Gaming. Scaling is not good enough yet. Dual GPU is fine for games. Triple is sometimes acceptable. But Quad scaling is terrible for gaming.

All clear, no errors. Artifacts only in stone giant with enabled Diffusion DOF (by F3 button) Seems driver issue. Anyone can confirm this bug?

[OC Nub]

Anyone find a program so change LOD with this card? So far nothing has worked.


Finally broke 47k vantage.

Good are you testing cfx on vantage ?
