Hey all, so I recently bought a new HD5870 after my old one was having problems (capacitor buzz, high temps), and I wanted to flash the BIOS to make the fan speed idle at default 50% instead of 20-22%.
Here's the exact model I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125326&cm_re=5870-_-14-125-326-_-Product
I made a bootable flash drive, put on the latest ATIFlash, and used RBE to edit the BIOS.
I saved the original BIOS from the card using GPU-Z, it originally read Duty Cycle Min: 22%. So I changed that to 50% (TMin 55C TMax 95C) , saved it to my flash drive, rebooted and flashed it. I then loaded back into windows and loaded GPU-Z/CCC to see what the fan speed was. It was still reading 21-22%.
So I used GPU-Z and got the BIOS from the card again, to see if maybe I flashed the original one instead. I loaded the new save into RBE and it reads Duty Cycle Min: 50%. Yet GPU-Z/CCC say the fan speed is still 22%. I tried flashing it again, only it gave me "BIOS already programmed".
Any help here? I'm thinking maybe it's because this card has two fans... but maybe not.
