Hello,
I have had AMD Athlon II x2 250 for quite a long time but now I decided to solve an old problem.
My mobo: asus m4n68t-m le v2
The problem is that Core Unlocker shows 6 cores in BIOS, checking them auto or manually ON doesn't really enable them, there's still "2 cores are activated" during POST screen and Windows or Linux see only 2 cores.
And I had them working, I am absolutely sure I saw 6 cores in Windows Device Manager but after BIOS reset (taking battery out because I couldn't get into it and I didn't see any BIOS reset switch on mobo) it stopped working, I've tried many "solutions" I found but nothing turned it back on, I tried possibly every possible combination of settings in the same tab as the Core Unlocker. A strange thing is when I turn off cores 3 and 5 I don't see that "2 cores are activated" on POST screen but Windows and not even Linux can boot (gave them like 20 minutes each, normal boot after full restart takes like 3 mins on Windows). And the opposite combination (3,5 off 4,6 on) makes no change, Windows still sees only 2 cores and the message on POST screen shows up too. I tried to check every core alone, and if I remember correctly cores 3 and 5 won't allow boot (I can check that again) but I can't get more than 2 cores. Turning off the 2nd core works btw and Windows sees only 1 core.
The CPU could handle +5% OC profile with 6 cores enabled at that time.
Rest of specs:
I can't remember exactly the name of the psu but it's 420W
GPU: Radeon HD5670 (oc'd in Afterburner)
RAM: 12GB DDR3 1333MHz, previously 4GB on 600 or 800 something, I don't remember exactly
OS: Win 10 Home
CPU temps never get above 55-60C even after 8hrs straight of gaming with average 90% usage
The only thing that changed between it working and today is a new 8GB stick of RAM but the 4 cores stopped working way before that.

I forgot about BIOS version, it was working on 0702 and stopped working on that version, updating to 0902 didn't change anything
