yes you can unlock core 7850 BE but You'll need an AMD chipset motherboard that has the SB750, which has ACC. Unlocked core is lucky
i have Gigabyte MA770T-UD3 motherboard and ACC, and what about 7750BE CPU can he be unlocked and what CPU will that be when i unlock 7850BE, triple or quad core CPU? and thanks for answering
and sorry if i wrote something wrong my english is bad
SB710-equipped motherboards can unlock cores, not just SB750 ones, as both southbridges support ACC.
The problem with unlocking Kuma CPUs is AMD itself found they'd unlock very early in their production, so they stepped-up their disabling/lazer cutting of the additional cores. Early samples would unlock, with some of them becoming fully-functional quads, but later ones wouldn't even unlock. I have a 7850 that speaks to the latter. It simply won't unlock, despite trying it in 3 different motherboards.
