Managed to get 3.4GHz booting, and then modified it slightly to get system booting at 4.21GHz!
Beginning of STRESS TEST results below.
I will post some of the values I have thus far, if you have any advice about how to improve stability or tweaks for improvements please let me know.
Current test running: Prime95 - BLEND - 2 THREADS

- 1.36250V - FAILED -> 7 MIN
- 1.36875V - FAILED -> 50 MIN
- 1.37500V - FAILED -> 50 MIN ?!
- DRAM Voltage to 2.12V, to see if fault happens around same time period, 2.12 = 2.10-2.11 in Windows - FAILED -> 8 MIN (Guess RAM doesn't like 2.12V :o)
- DRAM Voltage back to 2.1 - FAILED -> 1 HOUR, 16 MIN (2.1 = 2.06-2.08 in Windows, seem to have found the stable limit, CPU VCORE needs to be upped)
- 1.38125V(1.31-1.34~ Windows) - FAILED -> 5 HOURS, 11 MIN (Now we're getting somewhere!)
- 1.38750V(1.31-1.34~ Windows) - IN PROGRESS
