Title: Unlocking a Phenom II X2 550 BE on the 890GPA-UD3h
Post by: VenomIreland on February 18, 2011, 08:00:38 pm

I've tried all BIOS's except for FF, which I am about to try later tonight.

My problem is, that some boots it will succesfully unlock (and be stable, tested with prime95 for 6 hours before deciding it was) but most boots, it is like the CPU Unlock option has been reset to "off" (It hasn't, it just acts like it has).

Any help? Customer Support is useless.

EDIT: Going to roll back to FE, FF doesn't have the .5 increments anymore.

I have no idea why this happens. I've experienced this problem, too but in my case it's very occasional. Maybe the CPU isn't quite up to par or there's something wrong with the MB. Hard to tell.

It is a revision 2.0

I am going to try unlocking it again today, but this time I'm going to raise CPU PLL up a little and see if it helps.
