Good morning - I recently put together my new build, which features an Asus P5Q Pro Turbo, an E8400 running with a lapped TRUE, and ram native at 1066 (5-5-5-15). After getting everything set up and letting the AS5 cure a little, I OC'd the cpu to 4.05 ghz, upping the Vcore to 1.31 and setting the ram to a 5:4 ratio (which I hear works well on dual core setups), at 1116. I'm perfectly happy with this OC for day to day use - I may try to tighten that Vcore over time, but even if I don't I feel it's enough within the specified range that it's ok.

My question is, I tested this stability using Orthos, running small FFT's to stress just the CPU, and it was stable for 8 hours. Is that a long enough sampling of time? I tested the ram through Memtest 86+ and after 8 hours of testing and 9 complete passes, it had one error on the 2nd pass. Do I need to worry about that error, and is there any way (within the test results summarized on Memtest 86) to diagnose in which module the error is occurring? I'm concerned that one of my four 2 gb's is bad.

I appreciate any advice you can give me!

I'd clock your memory down a bit, change your multiplier, or increase your voltage and run another stress test with memtest 86+. Memory errors are a complete PITA when your data gets corrupted.

Upped voltage to 2.08 (top of spec is 2.1) and passed 6 passes of Memtest - looks good, thanks!

Keep in mind that most of these RAM chips are rated for 1066MHZ ***ONLY*** at 2.1V. 2.1V is not the max spec, its what the RAM needs in order to run at the advertised speed.
