I have an AMD Athlon II X3 445 which can be unlocked. I tried to unlock it but it freezes windows loading so i have to go back to 3 cores. My motherboard supports CPU up to 95 watts and has the ACC feature in the bios. When i enabled it on all cores and values set to -2 it froze on startup, then i tried all auto which somehow worked but i couldn't see the phenom in system properties? I then went back to all cores and values set to 0 and it worked again and appeared normal but the temps were high around 50c. When i rebooted it went into a bootloop once and then stuck onto the windows loading screen.
Unlocking CPU core and recommendations for CPU cooler?

How AMD made those X3 processors was they took 4 core processors where 1 core didn't pass spec and so they disabled it. Sometimes you can get lucky, win the silicon lottery, and unlock that core and it works no problem. Other times, as you have discovered, that core is locked for a reason. Sorry.
Yh because i ran cpu z and the 4th core was running but no L3 cache so idk if its the temperature. I noticed that if i unlock the core the wattage increase which my motherboard doesn't support? I need to also upgrade my cooler as im getting around 43c doing nothing it used to be around 30- 35c on my older am2 cpu but i want a cooler that doesn't need brackets as my motherboard has plastic standoffs so i can't remove the am3 socket. I was wondering if the coolermaster TX3 evo will be good enough.

Yeah the 4th core will run its just not reliable thats why you're having the problems you are having. Has nothing to do with motherboard support or anything else.
The TX3 evo is a good cooler and will work properly on an AM3 socket

I was right, it is the motherboard, i have a fx6300 and i can't overclock and get crashes. I checked online and people with the same motherboard have the same problem. so i wonder that is why the 4th core was not working with the athlon cpu.

That issue doesn't mean that you were correct, the problem with the processor may well (and probably is) completely be isolated from that. What motherboard is it? If the VRMs aren't up to snuff for a 6300 then overclocking will fail.
Like I said AMD disabled those cores for a reason, sometimes you get lucky sometimes not.
yh but....:

athlon cpu did unlock then messed up but if this board can't even OC then most likely it can't unlock.

No, that is not a correct assumption at all.
First off the 6300 is a 6 core CPU, even unlocked yours is only 4.
Also as I said the reason the core was locked and it sold as an X3 is because the core did not past quality level tests. Thats why AMD sold those chips as X3.
That is the only reason. The motherboard can't overclock because the 6300 is far more powerful than the Athlon you have, and the VRMs can't keep up with it.
