Ok so here's an update.

At first I was worried about my RAM (see sig). So I tested it at 450mhz (900mhz total) using memtest86+ by adjusting the voltage up to 2.1V. It passed with flying colors, meaning it can be 1:1 with the FSB at 450mhz, which is my upper overclocking limit.

So the next part was going from 3.4ghz to 3.6ghz. I tried booting my PC up at 3.6 ghz using a fsb of 424mhz, multiplier of 8.5, 1:1 memory divider at stock CPU voltages (Vcore 1.23 in BIOS). This OC POSTed, but windows did not boot. So I increased Vcore to 1.25 (did not change the northbridge or fsb voltage settings), and windows booted up. It also past 1 hour of OCCT stress testing.

Only thing I'm worried about is the temps. The max temp for my chip is 71.4 C, and with stress testing the load temps were up to 63 C (35-43 idle). I think this is pretty high load temps. What do you guys think? Do you think I need to reseat my heat sink (OCZ vendetta 2)?

I'm going to run 12hrs of prime 95 overnight and see if its stable. The next step is to get to 3.8ghz. I think I'm going to have to up my Vcore as well as play around with FSB and northbridge settings. Do any of you have advice for me?

PS sorry for being a noob at this, I tinker with computers in my spare time I'm actually a scientist.

Thanks a bunch!
