That's a sandybridge processor. Much better overclockers.

No need to adjust the PCI-E frequency, won't make any difference unless you need to go over 220 bclk.

You could, the 103 pci-e won't hurt anything, but won't help either.

True, unless you're trying to beat a benchmark or something there's not that much difference.

try 23x183, disable speed step, and try 1.325v

I had the same problem with my 920DO until I got faster ram. I couldn't get past 3.99 (stable)using dominator 1600 ram. Then I got some 1866 ram and I got to 4.2 GHz. Now running 2000 Mhz ram and am 24/7 stable at 4.33 GHz.

My personal experience with my sig-rig. Ram speed made a difference since its tied to the cpu overclock. You could try loosening up your ram timings and then they may be more stable at higher frequencies.

If it won't do it with that little, you're going to need to pump more volts into it. Plain and simple, especially with such high stress on your IMC with 3x4gb of ram...that's just ridiculous.

If you're going to overclock, don't be scared about it. I've been up to 1.65v on air cooling, and hit nearly 200*F
