No, it's a native Dual-Core

No it's not, it's a crippled Phenom I aka Agena. AMD never made any K10 dual core processors at 65nm.

OP, I doubt yours will unlock, the majority of them never did and reports of them unlocking didn't come out until near the end of their manufacturing. Enable ACC and you'll see if it does or not, but I know mine never did anything with ACC.

:(  damnn! why? but i have 785gxh SB710 chipset amd

My bad, I thought it was an Athlon II x2.

The Athlon x2's were just single core's "glued" together so you can't unlock those either. It's not a crippled phenom.

No you can't, there's nothing to be unlocked

Actually Uncfan, Loneninja was correct. The 7750 is a Kuma dual core which was nothing more than an Agena phenom with 2 disabled cores. There are 2 more cores on that die. At the time, AMD was still producing the last of the Brisbane X2 chips. Those were the native dualies. Native Phenom based dual core chips didn't come around until after the 45nm die shrink.

As for unlocking, I have not heard of it being done on the Agena chips at all. That may be due to the fact that AMD had lower yields and a larger percentage of the disable cores were actually defective. It could be it just didn't work on the Agenas, or perhaps fewer people had ACC available since the SB 750 was released fairly late in the Agena cores lifecycle and the 710 even later.

Give it a whirl. See what happens and let us know.

hey artards, here i come to save the day and set evrything straight

the original phenom quad core was made infamous for its TLB bug and its runaway TDP, this cpu was made with a native agena quad core die.

the agena core was used to derive 2 other cores, the toliman tripple core and the kuma dual core these were all derived from the native quad core agena

there have been very little if any attempts to unlock these cpus because unlocking a dual core 7750 with its 95 watt tdp would result in a chip with a 190watt tdp

btw only intel has been known to glue dies together, all amd duals quads and hexas have been native, exept for the recently released opteron 12 core which is connected by 4 dedicated hyper transport links, not thru fsb like intel

Well thats not true. TDP doesn't scale Symmetrically.

True, but I don't think that is why we haven't heard much about them unlocking. If it could be done, somebody would do it.
