Remembr one thing do small increments and overclock one component at a time try to run the other components at stock or underclock them till that time
hope that help you
Let's make it easier to read,
1. Keep your voltage under 1.55
2. Keep your HT Link as close as 2000Mhz as possible
3. Clock your CPU-NB to 2.6-2.8Ghz
4. Have your CPU-NB (not NB!) at 1.3-1.4v (Personally, I can run 2.6 at 1.25v...but 2800 doesn't even post at 1.35v) <--- I have 4 Dimms if that matter, maybe eith less it'll be stable
5. Make sure you're not using the stock cooler and it is seated properly.
6. If your have an awesome overvolting board like the Crosshair V, make you you type the voltage properly.I have set 1.9v onto CPU once.
Well you can use the stock cooler for 4.0, it's just not good, high temps and loudness D:
