Athlon II x3 c3 core unlocking problem

[DJRCB]

Hey guys have a question about unlocking the forth core on my athlon II x3

When I unlock the forth core I get bsod durning windows boot, sometimes at the desttop.. Says something about clock interrupt not received from secondary processor.. Can this be fixed with a voltage bump or is it a dead core?

After some playing around with turning each core off and on manually I found out it's core 2 that's causing the problem.. I thought if I can't get the extra core working I could take advantage of the L3 cache.. But even with the CPU unlocked and only 3 cores on it doesn't show any L3 cache. Is this because the athlon II doesn't have L3 cache?


Thanks for any help!

Athlon II do not have L3 cache....Yes yor fourth core is without a shadow of a doubt no good.

I am an undervolt enthusiast. When I undervolt my CPU a lot, it BSODs on stress test with this interrupt thingy message. So that message may mean insufficient juice as one cause (if there are others). Moreover, Whether there's an L3 or not depends on whether the chip is based on Deneb(Phenom II quad) or Propus(Athlon II quad). Mine unlocked the L3(it was dud).

Some have L3,some don't.
