i was tying to unlock my cpu today and i was lucky to unlock one xtra core is the is any hope unlocking the 4th ????
when i enable the 4 th core the pc boots normally untill it reaches the black screen with win 7 logo in the middle then the screen goes into colors and reboots ?
tried increasing the voltage the same result ???
most PII x2's and PII x3's are basically PII x4's with one or two faulty cores disabled. there's a reason why you can't use that 4th core and why AMD marketed it as a dual core, and you've pretty much seen it yourself.
