Possible... why? because its the same

today i was playing a little and found out that one core of my chip has trouble to do 2600 nb at 1.20v nb. so i unlocked the cpu and in windows i had 4 cores and checked with affinity wich core give me the error on that 1.20v .

it was core 3 , 0-1-2 running fine at that speed. so i went back to the bios and selected 0-3 and back to windows ...... zero fine , 1 (bios 3) error.
went back and selected 0-2 .... same issue , zero fine , 1 (now 2) error
again went back, selected 0-1 ......you would guess already .same effect.

so no matter if you select 4 or 2 , or stock , always the same core.....and you have a bad chip i think.
