Are your memory timings 3-3-3-8?. Or is it at 2-3-3-6?. If you don't know you can check on the side of the RAM or run CPU-Z and click on the memory tab.
Once you know, try the manual settings in BIOS and if you still encounter problems at 215FSB then please report back and state what timings your RAM is meant to be at.
Oh, one more thing. Run Orthos and test small FFT's as this concentrates on the CPU. If you get an error testing small FFT's then try and up the voltage for the CPU up one increment and then re-try. If you get no error in this test then that points more in the direction of the memory timings.
P.S: Lighters remove that sweary asap m8 (post 18) as it's not allowed on the forums. I'll delete this txt after it's gone
