Would it be ok to unlock the cores on a Phenom x2 550 BE and use the stock heatsink. I am going to eventually replace it, but for the time being i am stuck with the stock heatsink. Would it be ok to run it as a quad with the stock heatsink?

Not sure. I haven't seen the stock heatsink TBH. I would wait till you get a aftermarket one just because it will be more worth it and less chance of overheating.

Try the unlock.

Torture test with Orthos, OCCT, Prime95 or any tool you wish.

If the temps go above the max temps indicated by AMD (I don't know the max temps for AMD procs) then you gotta buy a new hsf. Else you could stick with it.

problem with that is, when you unlock the cores, the temperature diodes become useless. The temps will read completely wrong. I'm probably just gonna wait till i get a better hsf. better safe then sorry

i am really not sure, many people have had this problem. once they unlock the cores the temp reads like -1000c or something like that

I've just recently read that in another forum, the guy showed his temps and it was -250C. He disabled the core unlock and it read to around 45C.

In a previous article also here, there's no way really to check if a core really doesn't have any defect so even Tom's couldn't recommend unlocking a core. For your case I guess try to get a better hsf, it's the better be safe than sorry scenario I guess.

The numbers used are probably wrong, but it should get the point across.

I wanted to reuse my stock S939 HSF that came with my 3500+ if/when I bought an OEM 3800x2. The problem is my 3500+ was a 65W chip, while the x2s were 89W or higher. The sink just can't handle that much heat. I'm doing the same thing but reversed righti now. I'm using a stock quad core heatsink on my E6t600. The 6600 is an 65W chip, but I'm using a stock sink thats designed to handle more heat. As long as the stock sink can handle the heat, you should be good to go. Just look up the heat output for the chip you have, and the chip you hope to unlock it to.
