Unfortunately no. Power limit only helps prevent throttling. The only cards that have measures for vDroop are the ASUS Matrix and MSI Lightning IIRC. I think those cards have some kind of an LLC option available.

The author of the vbios editor stated he plans to code it for clock speeds in the future. But for now It only helps with increasing voltage to the GPU core. I've dialed in my OC to 1180 with 1.18v, so I set the voltage to 1.218v in the program (droops to 1.183v under load). Yesterday I had it set to 1.256v, but changed it because I won't be running the card any higher for the time being. I am/have been folding with my card 24/7 since April 13th.

jealoussmiley.gif well that sucks. Still looking for a way to keep my Vdroop undercontrol without needing to pump ridiculous amounts of voltage through it. 1.212 in AB = 1.137 load

I have never heard of VTX3D cards so i dont know what they are like. That Sapphire 7870 xt is a really decent card built on a light version of the 7950/70 Tahiti GPU. I would go with it out of thoose two. People have nicked named it a 7930.

7950 or 7870 XT ?????

definitely HD 7950. at the same clocks HD 7950 is 15 - 20% faster than HD 7870 Tahiti LE

http://www.techpowerup.com/reviews/Club_3D/HD_7870_jokerCard_Tahiti_LE/31.html

if you can spend a bit more go for the HIS HD 7950 iceq x2 boost. 950 mhz boost. the best built HD 7950. reference HD 7970 PCB. 8 + 6 pin power.more power phases than reference HD 7950. unlocked voltage. excellent cooler. card is 311 mm long. check if you can fit the card in your case.

Guys, CPU's OC better when their running colder, does this apply to graphics cards too?

I mean, with 1175c@1.3v it hits 75*c, If I can get temps down to high 40's and low 50's, will my card get a few more MHz?

7950 or 7870 XT ?????
Don't buy VTX, they are owned by TUL who also own Powercolor. Cheapest cards around and notoriously unstable.... Pay extra for a decent 7950 imho.
