LoadLine Calibration actually seems to be wreaking the most havoc, It might just be me but it would appear to be really far off.
At 51% (default) the vdroop isn't at it's worst but its far from stable. (1.5 dropping to 1.4 gradually, at which point it would bluescreen, at this point it would usually have reached about 58C but would be steadily climbing so I'm not sure if that was peak) (the way i understand it, turning this up should put a stronger emphasis on keeping the voltages stable, please correct me if I am incorrect in this assumption). To test this I bumped it up to 75% and did the same tests, it was absolutly abysmal, This test i had the vcore dropping from 1.5 down to 1.0 (and obviously bluescreening). So I did the test again with it at 17%, and it was considerably more stable but still pretty rediculous, 1.5 dropping to 1.3.
Yes Bios is up to date, last release was from 2009 i believe, so this board is definitely obselete now, rather unfortanate.
As for the cooling, that definitely makes sense, any recommendations for ways to cool the board like that? just looking around here, all the power relays are kinda tucked in behind my h50, and i'm guessing there's not any third party cooling equipment for this part of the board. and frankly i'm not willing to drop 300$ on a new am3 board for this processor, I'd sooner spend another 100 and get a brand new 2600k with a board. the speed on that is still way higher than i'd ever get with OCing on this baby.
and on another note, I'm noticing a pretty disturbing sound developing while it's under heavy load, About 2 mins into a benchmark i start to get a hissing/popping sound from my board, My first guess would be caps, but i've been unable to notice any damage, and it goes away almost instantly after throttling down. (only starts at about 55C)
