Core clock multiplier keeps changing for some strange reason. Tags: Intel Overclocking Last response: April 29, 2012 9:52 AM in Overclocking Share skyfox7 April 29, 2012 8:14:01 AM System specs; CPU: i5 2500K (multiplier 44x) MB: GA-Z68XP-UD3 Ram: Kingston, 2x4 8GB HyperX (188.8.131.52) VC: XFX Radeon 7770 Black Edition OC Here is 3DMark2011; I'm not sure what is going on here. According to CPUID the multiplier is 16x when idle but when I run prime 95 the multiplier changes to 44x. The bus speed is also listed as 100.3, but in the bios it is listed at 100. ots When I am in the Bios, if I disable c3/c6 option, windows never boots and my system keeps restarting itself. Has anybody else experienced this? I'v checked all the ram settings, they seem fine.
