I had to get my CPU at 1.5V to get stable at 4.0GHz and at 1.52V now for 4.2GHz, push the CPU volt's higher if you can. your well within good temp's. But your CPU might be one of the bad ones, try lossening the memory timing's, and increaseing the memory speed. I tried running my OC with a lower memory speed and it failed, but a higher mem speed seemed to make my OC stable. Try keeping the HT speed close to 2000MHz and NB somewhere near 2800MHz. My NB is at 1.3V, CPU-NB at 1.32 and memory at 1.71V if this help you
So you are saying that I should run my ram even though its rated @ 1600 to over 1600? would I need to up my ram voltage?
Loosening the ram timings = overclock failure.
Maybe I should increase ram speed and then loosen ram timings? its @ 1448ghz atm
