How A64s are locked

post #1 of 31
Thread Starter 
I was wondering if thw following was true:
all A64 are manufactured w/ the multis unlocked, then they go under preliminary testing, then multi locked using JTAG programming

Is that true?

They're not completely locked, you get your normal multi and below. FX's I believe aren't locked. Not sure how they lock them but nobody has found a way around it as of yet. The XP's had a few different ways to unlock~ hopefully somebody finds a way for the 64's.

A64 are up multipler locked but allow lowering multis. However, the FX processor line is completely multipler unlocked.

Not sure on how AMD locks them though.

Locked means the multi won't go past a certain point on a chip. Every chip can utilize a lower multi, just not a higher one if they are locked.

Yours is not unlocked im afraid to say.

I believe the lock is achieved through a certain cut within the processor die, but im not exactly certain.

i was thinking if it was locked using JTAG, it could be possibe to undo the programming, so it will go back to its unlocked state

If the AMD 64 is not an FX line, it did not prove itself in testing, hence the locking of the upper multipliers. FX's proved themselves, and are left as is.

I can't locate any hardcore information regarding the locking, whether it is software or hardware locked. I am assuming it is hardware locked like the XP line.
