Ok, I kept the RAM volts within the suggested at 2.15v. With that and 5,5,5,18,26 timings I maxed at 430-435 Mhz stable. 440 failed with errors.

Now I brought it back to ~390's Mhz and trying to OC the 5200 CPU. I upped the volts 0.012v and CPU-Z shows it at 1.312 - 1.344. So far its failing Orthos at 2771 Mhz. 2750 seemed ok so far but not 100% or 24hrs testing.

My question is what is a good safe and healthy volts I should use for this CPU? I can up the volts 0.025 at a time...Should I increase it a little more?

Oh, my MB temps are a bit off due to the bios, but core temp shows in the 30's under orthos!
