280X CROSSFIRE VS 290X

[robertchalmers1]

it does now in hwinfo it shows a max voltage of 1.300v just managed to do a full run of valley at 1200 clocks that i never managed before

200-300?

Use gpu-z to see if it actually shows the voltage increasing under load.

the TDP limit ir whatever its called

If you want more than 1.3v, let me know. 1.3v is the max safe limit though, so any further and you're taking a risk.

 

[robertchalmers1]

with the limit now set at 1300v does that mean the card will never go above 1300???

I set the stock voltage at 1.3v and removed the boost part of the bios.

 

[robertchalmers1]

so if i set the power limit % at 20 does that mean it will boost over 1.3v or is it locked in so it cant go any higher than that???

1.3v is your stock voltage and now your maximum. You should always use +20% power limit as well.

LOL.

thnx just wanted to double check i wouldnt go above 1.3v also the atiwinflash worked for me. got fed up waiting for a movie to finish and get the usb stick back to gave it a blast.

scores jumped from about 3550 upto 3860 with a couple of runs hopefully manage to get it near the 4k mark most cf 7970/280x users have

Now see how high those clocks can go

Btw, good work Matt.

exactly excellent and much appreciated as well. guess thats my fri night sorted playing valley all night long

No worries. Its been a while since i tweaked a Tahiti bios but good to see you can still up the voltage if required. Enjoy.
