Right here goes.
Have an Athlon 2 x3 425 @ 2.7 stock
Unlocked it to a Phenom 2 x4 B25.
Been completely stable for the last few months @ 3.21 on the 4 cores on 1.425 stock voltage.
Started getting Blue screens the last 2 days and Ive narrowed it down to the cpu.
If I leave it as a tri core @ 3.21 its stable.
If I "turn on" the 4th core its blue screens.
However if I up the core voltage to 1.475 its stable again.
Can a 4th core suddenly become unstable after months of use??
Is it just luck of the draw that its started acting up and probably the reason it was locked to start with.
And if 1.475 vcore too high?Or can I run it at that volts?
Is it time for a cpu change??
Temps never go over 55c at the higher voltage.
