I've got gigabyte windforce version stable at 1150/1575 at 1.25v. I do not recommend gigabyte though because their vrm cooling is not very good.

You can do that? which bios?

I did some further research into this and this is what I've come up with. This card is in fact voltage locked, but not in a normal way. Turns out my card has an FZ1 bios version which was only installed onto very few cards because it caused considerable amount of users to have VRM temp issues...

NO. I can confirm Gigabyte 7950 windforce with the new bios at 1000mhz stock is NOT voltage locked. I got mine 1 month ago and I could increase the volts to 1.3 in afterburner. It doesnt make much difference though, because max stable clock is 1150/1575 at 1.15v. 1175mhz will produce artifacts...

2 weeks old gigabyte 7950 maxed out at 1150/1575 1.15v and would not go further no matter the volts. ASIC 63,9%, vrm temps ~90 degrees, core 65. Not the finest piece work I presume.

I described my case setup, my way of stability testing and clocks on previous page near the bottom. I am now running with the case open. I have not yet tested in any benchmarking/stress tool. I'll post results when I have the time to get into it. 13.1 for the moment, but I might take your advice...

Ok, I checked vrm temps and they are a bit high while playing FC3. 94°C max, so I turned up the fan additional 5% to keep it in the mid 80s. Looks like standard stuff on most gigabyte versions. Im gonna try the method of a case fan installed close to gpu and see if I get better results.

Hello, first post on this forum. Lots of usefull information to be found on these pages. thanks guys. This is what I've been able to achive on my brand new gigabyte 7950 windforce. ASIC 63,9%. It came with new bios with def. clock at 1000/1250. So far I took it to 1150/1575 at 1.15v stable in...
