I ran SPI 32M and 2 hrs prime and it seemed to be stable. Then tonight I noticed my temps at core 0/1 (especially at core 0) were bigger than core 2/3 and after a SPI32m it produced an error.. Generally core 0 can reach 10-12Celcius higher than core 2/3. Core 1 is 5-6Celcious higher than core 2/3, but low enough not to cause a problem with stability in torture tests.. The fact is that cpu0 which depicts by far the higher idle/load temp is the only one that causes the instability even at 1.4vcore. It reaches at 75C-78C sometimes and of course causes instability, while the other cores don't have problems whatsoever. Cpu1 reaches max 70-71 cpu2/3 max 68-69..
I tried to up the vcore to 1.425 and 1.45 but it only made cpu0 reach 75-78C quicker.. So the problem seems not to be the vcore but the hight temp that only this core depicts under load..
So what do you think is the case here? Do I need to test something else in the settings? Or are we talking about a uneven cpu surface? It could also be my Ultra 120 extreme that has the problem..
What do you suggest me to do ? It's really weird.. Cores 1,2,3 seems to have no problems with temps whatsoever.. 1.4v seems to be ok.. 1.45 certainly does not help all it does is raise more the temp in the cpu0, which is already high @1.4
Any ideas? Thnx in advance
