Current Configuration:
O/S: WinXP Pro SP2
M/B: EP45-UD3R v1.1 BIOS F6 (tried F4 & F5 also) less than 60 days old
-Running Optimized Defaults; EIST Disabled; no O/C ATT
CPU: E8400 3.0 GHz (9x333=3.0GHz should be @ stock)
NOTE: 2nd CPU; RMA'd first one as I suspected it as the problem
Memory: OCZ2RPR10664GK (4GBx2 - also tried running one at a time)
PSU: Antec SP350 350W PSU
Video: EVGA Nvidia 7600GS PCIx16 edit
CPU running fine at 3GHz (333x9.0) until recently. Suddenly my computer will only boot using x6 multiplier. This is not a throttling/stepping issue as EIST is disabled, and the same situation exists when the CPU is at 100% load as when it is at Idle (running Windows Media Encoder which is disigned to use mulitple cores). Something is forcing the CPU to run at no higher than 6x multiplier which results in a overall CPU speed of 2.00 GHz. The M/B will not boot the CPU at 3.0GHz even when forced. After clearing the BIOS (shorting the jumper) and resetting to Optimized Def., the motherboard will attempt to boot the processor at the specified parameters (333x9 in this case) and it will not boot but immediately fails and reboots, and upon entering the BIOS, it informs you via a message that the previous boot failed due to overclocking/voltage issue. I am not overclocking. From this point it will force x6 on every boot until I clear the CMOS and try again (with same results I might add). I can verify the clocking being forced as it is shown on the screen during the POST. It seems the M/B and CPU will not pass POST as 333 x 9; this is a brand new CPU; RMA'd first one as I thought it was cause of the problem. Please help! My computer is way too slow now @ 2GHz. M/B less than 60 days old.
