BIOS flashed has stopped the eratic settings not sticking behaviour

As for Stress testing i discovered somethig counter intuitive

HT enabled does indeed cause more heat while stress testing in prime (small FFT) however it will crash much faster with HT disabled while using prime

seems wired but very noticable

1.25vcore at 4.5 GHz HT enabaled was alot hotter low 90s
it easily ran for four or five calculation checks in prime however i was unahppy with the temps (to run while i was away) and manually stopped it

so i rebooted disabled HT and started prime, great temps lower. Bang crashed within about 15s

Well this makes it easier as im not too worried about the temps in these synthetic tests and if for some strange reason prime pounds my cpu more with it disabled all the better

did a ran last night while i slept HT disabled (since it seems to be harder on cpu for some reason), turbo enabled (probly always was with the buggy BIOS as it would drop core speed and volatges at idle) 4.4Ghz, 1.225 vcore, 1.92 vin, 1.150 ring, +0.1 on system agent, cpu analog and digital, i left XMP on and uncore on 35 so it auto oced to 4000 (im gettign sic of the stresstesting and would be happy for this to be my final safe oc)

it survived all night (small FFT) about 8 and a bit hours then just before i leave for work bam restart ( i reackon prime likes to mock you like that, it senses you have looked at the screen and are happy and then stabs you in the nuts).

so i bumped the vcore to 1.230 should be good now fingers crossed

I know prime is a solid test for stability but I am starting to wonder if its a little too hard

as any had experience with Intel extreme tuning utility

in particular does how long do u need to run it to assure stability ie 24 48 hours

and if it passes aforementioned time has any had ther system crash due to instability not picked up by this programme

in the past if I passed prime 24+ hours in both blend and small FFT
it is rock solid nothing will crash it

4.4GHz stable
1.235 vcore
1.92 vrin
1.150 vring
xmp2
uncore 4000

18Hrs small FFT with HT disabled
BF3 runs fine with HT enabled

Temps much better in game high 50s

I still want to delid :D

but I wear panties
