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

Can anyone confirm that heatsink removal voids warranty and if manufacturer will be able to tell? Eg phase change TiM removed or disturbed?
Cheers
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.
cool that they use good TIM now and not spluuged on like gtx480's

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.Quote:

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.
Sure is a pretty end result though!Quote:

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.Quote:

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.Quote:

All clear, no errors. Artifacts only in stone giant with enabled Diffusion DOF (by F3 button) Seems driver issue. Anyone can confirm this bug?
Anyone find a program so change LOD with this card? So far nothing has worked.
Finally broke 47k vantage.
