Mine came with 031 and the downclocking to 925 problem. I ordered from newegg on the 20th

That is disappointing. Does updating the BIOS void your warranty?

Where did you download the bios from? And where/what guide did you use to flash? I got the EZ and that damn throttling is unavoidable with .31 bios, wanna flash to 0.28 bios...

I'm using +8 voltage boost as some members mentioned it worked and I'm using 13.3 beta 3 catalyst drivers

http://www.powercolor.com/us/support_warranty.asp seems to focus on physical modification but bios probably could be considered a mod as well, I saved my original bios in case I need to flash back and send the card in

how to flash bios http://www.overclock.net/t/1353325/tutorial-atiwinflash-how-to-flash-the-bios-of-your-ati-cards
bios 028 http://www.techpowerup.com/vgabios/131805/Powercolor.HD7870.2048.121106.html

I haven't flash my bios yet but some members said that 028 bios fixed the problem, I'm a little scared that something might go wrong flashing the bios since the EZ edition only has 1 bios tongue.gif, I'm trying to figure out another way to fix this without bios update

Doesn't work for me! Even just bumping from 975 to 1000 on core speed, the throttling starts and @ +8V boost, it stays more time at 925mhz core speed than the OC speed. And at +20V the throttling is every second! I am done trying, time to flash to 028 bios!

Alright, thanks. I will probably do that when I get mine if I have the same problem. I'm excited! Coming from a 6850, this should be a huge jump in performance for me. What kind of FPS and settings should I expect on FC3 and Skyrim with an i7 3770K at 4.3?
