I have a used Gigabyte GA-MA785GM-US2H the CPU I used is a AMD Athlon II X3 455 triple-core processor I have unlock the from the AMD Athlon II x3 455 triple-core processor to a AMD Phenom II X4 B55 Processor Via Advanced Clock Calibration, but I won't stick it go back to the Athlon II X3 455 even time I shut down the PC. Is there any way for me to keep it unlocked?

replace your bios battery..

bios should save all settings when the computer is turned off..

But if I do that all of the bios will be eased.

I believe replacing the bios battery reverts it to default settings not erasing it.

Ok but that won't keep it unlock.

Replacing the battery may solve your problem of the bios not holding the settings, have you tried playing around with the jumpers as well? Lastly, try updating the bios. I doubt it will do anything but it's worth a try if you don't have the latest bios.

When you unlocked it using Acc, did you remember to save the setting?
As mentioned replacing the Cmos battery is also a good idea,, I'd leave the jumpers alone though

Yes I do but every time to do that the PC shunt down.

I had to check, some people alter bios settings and forget to save and exit, they just exit and wonder why the settings didn't hold :) 

How are you setting the four cores up? using the 'all cores' or 'per core' setting?
I found setting the 'all cores' to enabled does the trick, it may just be that your chip was locked because the fourth core was unstable

Just a quick question- does the computer actually function and allow you to get into the OS and confirm everything is running as it should?

I only ask because my X3 455 would let me "unlock" the core so that it was being ID'ed a a B55 in the BIOS screens, but would then crash the computer before windows would start. I eventually determined the extra core had to just be bad. I had the same issue during that time with the BIOS turning off the 4th core when I would restart as well.

PS- I forgot to ask, does anyone know what a X3 455 overclocked to something like 3900mhz benchmarks compared to a X3 455 with the 4th core unlocked? I only ask because it was surprising to see that I was coming within 10% or so of my Phenom X4 965's stock bench scores with my OC'ed 455.

easy..

3 x 3900 = 11700
4 x 3300 = 13200

well, in multithread application, 455 with 4th unlocked core still faster :D

Maybe OP has an unstable bios, try to upgrade it to the latest bios available..

if the problem persist, the i think this processor is nearly defective one..

It's per core also in the CPU core control which is set to manual CPU core 0 can't be enable or disable but CPU core 1 and CPU core 2 can be enable or disable.

Ok, drop the +2% to +0% and have it enabled (obviously), you don't want to be pushing the cores when one already may be a bit wonky,
if you have the option select 'All cores' rather than 'Per core', if the chips good it will automatically utilise the fourth core, if not then it will relock it and not use the bad core

Ok I'll try it and let you know.

Ok so I as you all know I've been trying to Unlocked my AMD Athlon II X3 455 triple-core processor to a AMD Phenom II X4 B55 Processor I did what motopsychojdn told me to do, I did that but it still didn't work I want back into the ACC and did this:



The EC Firmware Seection was on Normal so I changed it to Hybrid after that well you know what happens next right?
