Ok, I'm radically changing this post because I now have half a clue (I think) as to what I'm doing.
System
Gigabyte 990FXA-UD5
AMD Phenom II X6 1100T BE (3300Mhz Stock)
8GB DDR3 Kingston HyperX (1600Mhz, 1.65v)
I've gone through my BIOS and manually set my RAM timings/voltage to manufacturer specs (9-9-9-27 + 1.65v according to the Kingston website), leaving everything else set to their default values, but taking things off 'Auto' where possible to prevent power/performance fluctuations. I've also disabled AMD Cool+Quiet for the same reason.
As I mentioned before, the Phenom was stable OC'd to 3800Mhz (200Mhz FSB + 19x Multi) on stock voltage but BSOD'd when I raised the multiplier to 19x (3900Mhz). To combat the BSOD, I stepped the CPU core voltage up one increment at a time until the system stabilised at 1.424v. I've run it through a few tries with wPrime, which caused the original BSOD's, and it seems fine now. I'll run Prime95 for a few hours tomorrow when it's not 4 in the morning.
Considering the system now appears stable and that temps are within acceptable working limits, have I succeeded in reaching 3.9Ghz safely? I'd like to reach 4.0 tomorrow and stop there, but I'm concerned that I'm now approaching the chip's listed upper voltage limit (currently 1.424 of max 1.475V).
Firstly am I close enough to the voltage limit to be damaging the processor and, secondly, am I going about this the right way? I feel like I'm missing something obvious! :S
Thanks in advance for help
