Great, thanks! Basically, I only need GPU-Z to download FW, and VBE7 to edit and save it… How do I upload it again? ATIFlash?
Edit: tried it on one GPU - failed. Got screen blackouts, AMD driver crashes, and after that BSOD.
When I tried to edit FW - it gave me a note that it detected UEFI part…and that settings will only apply on normal FW.
1. Do you have those UEFI blue light buttons turned on or off?
2. I suppose that core frequency in modified FW should be the same as in cgminer?
Hello mate, sorry, I didn’t setup notifications on this thread.
Yes the blue button is an undervolter’s savior, press it down, reboot and you have the factory loaded VBios. Press it down to turn it off before you reflash with atiwinflash.
I wouldn’t worry about the core frequency, you change it every time you load CG Miner, leave those as default.
If you flash a bios when the blue button is pressed down you are overwriting the UEFI partition, so generally you shouldn’t. But if you are like me and you are a show pony you can flash with the blue button pushed down, looks mad at night, just be sure your settings are stable before you flash.
