I am currently running: Athlon 3700+ San Diego ASRock 939 Dual SATA II 512x2 OZC PC 3200 2.5-3-3-7 I have my CPU at 245 x 11 giving me 2.7GHz. This thing absolutely screams but my memory is letting me down because it wont boot unless I cut the ratio to .83 making it run at 192mhz X 2 (DDR384). I figured I would try to set the multiplier down to 10 and the FSB to around 260 making the Memory run a little over 200mhz. When I set the multiplier down in BIOS it boots up fine and reads the correct clock frequecy..but when I get into windows, CPU-z says I still have the 11x multi and my CPU is running at 2.86ghz. The system is way to unstable to run at this clock speed. Everest home edition is also saying I am still using the 11x multiplier. When I go back into BIOS the multiplier is set to 10x... This is confusing the hell out of me. Does anyone know what the problem might be?? Am I going to be stuck with a slight performance loss? Thanks!
