Made all 3 of the aforementioned changes, prime95 ran LONGER... maybe 1.5 min? Temps peaked at 51*C right before the crash.

Hmm, think some nicer 2x4gb ddr3 1600 ram would be able to help push me over the edge?

I doubt it. My 955 is a C2 and I can only push 3.8GHz at the most (3.9GHz but it's stable for a few minutes.) What stepping is you 955 again?

I'm honestly not sure how to check that. The mfg date on the cpu itself says 2009 if that helps.

Go into CPU-Z and tell me the Stepping/Revision number. Example - RB-C2 or RB-C3 (that is the revision, which is also the stepping.) The stepping in simpler terms under the title "stepping" is either 2 or 3. Telling us this information can better help us in understand how far you can push your CPU/ what your limit is.

I would return the CPU-NB and RAM voltages back to stock and change the cooling and then see how long Prime95 lasts.
I'm suspecting core instability.

If he hit his wall, then he hit his wall. No matter how much voltage, nb frequency, nb voltage, cpu-nb frequency, cpu-nb voltage, etc... you throw @ a C2 it's not going to get past 3.8GHz unless you have some miracle chip.

Its a C3 according to CPU-z... Does that help at all?

Drop your HT speed to 1800 mhz. When I was ocing my PhenomII 940 antying over 1850ish mhz would make it unstable.

Yes it does. You should be able to hit 4.0GHz - 4.2GHz or even higher if you really push that thing.

Fringe, any thoughts on where I should tweak? Or trents?
BTW changing the HT to 1800 helped a LOT, instead of bombing out in 10s it went about 90... And now I am experiencing a clean bsod, not just a crash.

Its known that lowering the HT Link Speed increases some stability. Its not 100% proven but in many cases people have got more stable OCs doing so. Here are my steps on how to get a stable OC.
1. Fix your ram timings. Unstable ram timings = unstable OC PERIOD!!! If you don't know your timings and ram voltage or if it's not printed on the side of the ram module, call your ram manufacturer and demand them to tell you what timings to run
You can manually do this all your self, but why bother when you can just get recommend timings. Now you can tighten and loosen the timings if you are going to OC the ram, but you can do that in a later OC chapter. For now just tackle the CPU and NB until you get a stable OC, then worry about OCing the ram later.2. Find a sweet spot with voltage and frequency.. Up the frequency on default voltage till you crash, when you crash up the voltage by 0.25 mv or the next notch up, and continue the same process of finding your max frequency per voltage increase. Do this till you find your max.... It will take time but in the end you will find out what frequency go with what voltage level.
3. Don't worry about CPU-NB or CPU-NB Frequency... Just leave it at auto..
4. The NB is just like the Core, find the sweet spot for frequency vs. voltage. I got mine to 1.300v @ 2400MHz. You can start there and work your way around it, or you can manually find your own limit
.If I made any typos, I apologize.. I really didn't feel like going back over it thoroughly
. Take care and I hope this helped. I might make a video on my Youtube channel some time later explaining how to OC on the AMD platform
If you need to contact me for any OC questions ASAP, here's some of my contact information.

Just hit my up with a DM on either and I'll try to help ASAP.
