I have an AMD 7750 BE on an ASrock N68C-S UCC and ive read that the 7750 BE has 2 hidden cores that can be activated but can i do it on this mobo? The mobo has a UCC function (unlock cpu core) but when i turn it on the cpu is still a dual core. The bios has been flashed.
It should at least try. Read your manual a bit more or link me to your motherboard on their website so I can take a look.
Also remember about what dokk2 said. Even if they unlock, they might not be stable. AMD sells quad cores with defective cores as dual cores. Sometimes they sell perfectly fine quad cores as dual cores in order to keep up with market demand.
If quad doesn't work, you could also try unlocking only one core.
