Hey guys. I just flashed the BIOS on my ASUS P5B-MX / WiFi-AP Motherboard. I upgraded from version 0501 to 0702. However, after the update i can't set my RAM to 667MHz as I could do before. It keeps it at 533MHz. I use Transcend PC5300 RAM. It also says "Unknown CPU detected. BIOS upgrade is required to unleash its full power." when I start my PC. However I press F1 and it continues to Windows. Please help.
