I've following the guides here and use RBE to mod the 4850 bios for 1.2 Voltage Mod. It doesn't work. I can boot fine with the modded bios, but once it enters Windows, my monitors goes to sleep mode and blanks out. I've tried several bios, including my original one. They all exhibit the same problem after volmod, although they work fine without the volmod. I'm using a Powercolor 4850 with CAT 8.8 on Windows 32bit Ulitmate. Here is a screen cap of the RBE clock screen that I modded. Can anyone provide me a working bios voltage mod? Thanks in advance for any assistance.
