Could be you have a chip that the core you want to unlock is really bad and thats why it wont. that is the most common for it not unlocking. You could try uping the voltage a tad see if it helps it might or might not.

I already tried to incrase VCPU,but not successfully,If you could give me some values like how much to rise it,It could help.

I dont drive tonight so i will. Also have you read thru the reviews on newegg for this chip. Seems alot cant be unlocked for the other core.

When i raise voltages i do it by the smallest amount possiable at first then check stability and temps b4 going any higher. When i get home i can tell more. this is specs for that chip,  0.875-1.40V
