and it goes fine for 29 hours in prime but then one worker fails. So I logically set 1.25V and one would think it will be completely stable, but to my surprise, prime itself crash after 8 hours or so. So I might end up with [email protected]
again.. But it doesnt make any sense, as I see ppl here having their chips on 1.4V etc., and 1.25V isnt really high
ivy is also about working the vcore very carefully,
made me think about something sin0822 said in his guide, how ivy behaves under ln2 etc..
i wouldnt go from 1.235 to 1.25 in one step tho, just stick to the 0.005V increments , and first try 1.240, then1.245...and then 1.25V,
not sure what else there could be wrong with your vcore up, and getting worse results..
Under LN2/DICE: Temperature is more important for high clocks than voltage is when it comes to Ivy Bridge. Also under LN2 higher vcore might not yield a higher clock, as it will add more heat which can have an opposite effect. So while at 1.84v I might do 6.6 GHz if I increase to 1.86 I can only do 6.55, but if I lower the vcore to 1.83v I can still only do 6.55,
it is all about working the volts very carefully. I should take a second and note that Ivy Bridge is an extremely tough CPU, it is very hard to kill, however you can kill it if you go above 1.6v on air and ~2.0v on LN2. Ivy Bridge also seems to be more resilient to degradation than Sandy Bridge was, however the heat produced by the CPU can cause degradations when above what Intel recommends.
the way i do my oc's, is find my stable vcore for any oc, then change to offset, see if it is stable,
then i just at 0.005 or 0.010V, and let it run like that, never had problems with it doing it that way,
so i think its strange you cant/couldnt at more vcore
