oh and srry i have a Noctua NH-U12P as a cooler and Antec 900 case i heard this cooler gets that chip to 4GHz no prob.

Try this, 4Ghz on Air may not last 3 years, but you will likely want a newer socketed board before then anyway >>>>

This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

^^ This is slower then your ram's stock speed so you can run tighter main timings ^^^

Set to all highest below, then later lower one by one testing with memtest86+ as you go.

CPU Vcore….……….........................:1.32-1.38 <<<< All up to you and your chip/cooling.  Please do check with CPU-z as to how much of a Vdrop you have from what you set in the BIOS to what you actually get at idle in windows.  It may be up to or more then .6 of a difference so you will need to adjust accordingly.  Some chips get 4Ghz on 1.28 actual some need up to 1.34 actual.  So set somewhere in the middle and see if you can boot it thru.  Set high so you for sure can then lower later until it fails then raise back up a notch or two.  I am using 1.38x set in BIOS for 1.32 actual in windows

CPU Termination…..... 1.200V*.......: <<< 1.2-1.32 (Set this, Auto will WAY overvolt this past what will kill a 45NM CPU if you leave it in Auto (I am using 1.32-1.35 for 450 FSB)
