Hi guys!!!\n\nI made an upgrade from Thunderbird 1333Mhz to T-bred 2200 on my A7A266\nrev.103 1012 Bios.\n\nAfter a day of BIOS tuning and B.S.O.D. problems, i got a totally\nstable system!!! 1.65V Vcore set / 3:4 CPUxMemory rate (I´m using\nPC133 SDRAM)\n\nMy question is about AMD CPUinfo that show my system running at\n2020MHz...\nSandra Pro shows a good performance: 7679MIPS Dhrystone ALU\n\nAnyone could explain me how I can´t change the CPU multiplier or CPU\nfrequency without hang the system? I set at 13x and 100/133 and works\nflawlessly! The boot recognizes XP 2000+ processor.\n\nThanxs!!!
