Unlocking athlon ii x3 445

i have a biostar AM3, athlon x3 445.

When i unlocked the 4th core it was a Phenom B45. But the 4th core was unstable.

I manualy shut down the 4th core but kept the L3 cache so essentaily its B45 without the 4th core.

Does any know if this would cause more problems with 4th disabled but the L3 cache still in use on 3 cores?


thanks, im the new guy

  1. L3 is shared memory, 1-2-3-4 cores will share it :) Gratz :)
  2. gotcha, makes sense. Thanks everyone
  3. No problem !
  4. I thought Athlon II's did not have L3?

    The first few batches of Athlon IIx4/x3 CPUs were not propus but were instead denebs with disabled L3 cache. Newer propus chips do not have L3 because they are not made from the same deneb.

    ^ Correct...

    The X3's are the salvage yard for dysfunctional cpu's. Open cpu-z and check for the "revision" on the cpu tab. The 445's are the newer C3 stepping as of 5-10-2010 made from Propus C3 640 or C3 Deneb cores. So OP has a locked up C3 PhenomII.

    AMD is going to continue salvaging it's dysfunctional 4 cores and use them as x3's, if demand becomes so great they may lock up some healthy X4's to meet demands.

    If I were going roll the dice on a X3 today I would buy a 445 and if the fourth core was bad I still would have a solid C3 X3 to overclock.
