Unlocking Sempron 140

Hello,

I recently picked up a sempron 140 with the hopes of unlocking it. I have a GA-MA785GM-US2H. Bios Ver. f4. 4 gb OCZ DDR2.

I've read several instructions - go to bios, enable ACC, put on Hybrid, turn off smart cool (?).

When I save f10 in bios, the board shuts down, waits a second or two, then tries to repower but turns off immediately. Then it's locked down untill you reset the bios on the jumper.

Anyone have any ideas? I've read that maybe the bios needs to be rolled back? Maybe the memory? What do you think.

Oh, and by the way, I was able to try this with two different processors and I'm getting the exact same result. I know it's hit or miss if it will work, but I thought before i just chock it up as it won't work, i'd ask for some tips or hints.

Thx!

  1. It's possible your cpu is too unstable with the extra core unlocked. I wouldn't change the bios unless you have another problem.
  2. I had success with the U3DH board version and my Phenom II x2 550 just by setting it to hybrid.Maybe you don't need the other settings?
