Another unlocked Kuma 7750.

"CPU: Kuma 7750 0909BPMW(not ES)
MB: Asrock A790GX/128M

In BIOS, He have Changed only the ACC(Auto)
And, He said that 4 cores was displayed in CPU-Z, Everest and TaskManager."

기글 하드웨어 커뮤니티 게시판 - ㅡ.ㅡ; 쿼드코어 인증샷? 머리아픔...

J.J Dragon have taken a picture for verify Unlocked-Kuma 7750.
And He said as follow:
I think that ACC doesn't seem enable Kuma 7750 to Quad-Core, and All of AUTO, PER CORE and ALL CORE settings has failed.

And, Kuma 7750 BE was changed into Opteron 1300 in CPU-Z

Now, I have trying to figure out the exactly way for Unlocked Kuma.

The situation of research until now, The way for Unlocked is not clear and the various and complicated parameters/conditions seems to effect upon Unlocked process.

p.s. Sorry about My Eng is bad

Disadvantages I'd say..if they have to use the same processors for dual and quad cores. Processor is effectively quad core, but is sold with less than 60 USD..can't be good business for AMD.

Well... no. You are unlocking them at your own risk because if it did pass all of their quality control I doubt these chips would've ended as two core instead of quad. So these are salvage parts and I don't see how it is bad business to sell the chips that would've been thrown away otherwise
