well, call me old school, but I don't truly trust those software OC methods LOL! when seeing voltage monitoring an adjustment screen I always see at least one voltage off a bit and when applying changes it seems like it alters that one too, never mind though probably it works fine (used that method for below 48x multi clocks once or twice).
anyways! I did another suicide run with my chip using my room AC outlet to serve as Cold Air Intake for my system hehe - mind that I calculate Dew Point when doing it and make sure I have around 4C safety cushion between calculated Dew Point temperature and lowest temperature of air inlet to my system (computer has a temp sensor on intake fan shroud).
it produced air intake temperature at front (internal) 360 radiator at 8-9C
water loop temperature dropped to 13-14C once stabilized at idle
results are ... well ... not great he he ... my chip sky rockets voltage demand past 5GHz to be stable and so I was able to stabilize 5.1GHz under IBT Standard 10 rounds (no whea warnings in logs), but it called for ...1.648v vcore under load ... it hit briefly 105C on one core a few times, but die downclocked only once at very end of test (round 10)

did some benching with SuperPI 1.5, 3dmark11 & Vantage and all got improved except for 3dmark11 which kept getting me slightly lower score than with CPU at 5GHz ... hmmm...
at 5.1GHz SuperPI 1.5 32M calculation completed in 6m 35.064s
Then I went for 5.2GHz and since I couldn't stabilize with IBT (temps) I sort of guessed working vcore a bit, basically allows me to load Windows, run SuperPI or CPU-Z validation ... at 1.74v actual vcore ha ha! tried benching, but CPU craps out under load (more vcore needed) with WHEA in logs ... and I didn't dare to raise it further for sakes of safety of my CPU (and my sanity) ... it wasn't far away, but still ~1.775v for a stable 5.2GHz sounds like crap LOL! ...
at 5.2GHz SuperPI 1.5 32M calculation completed in 6m 28.494s
tried booting to 5.3GHz, but even with 1.75 it won't boot without crapping out, so no go. I guess I learned the voltage/clock limits of my CPU today, and since temperatures don't matter much anymore (even lapping IHS wouldn't help me much) I am officially done with need for speed and CPU modding for now hehe
was a fun ride though, enjoyed it thanks to this forums
