Thoroughbred-B core
2200+
(DUV3C) 1800 266 (133*2) 128K 256K


from the link I gave....

The "U" at the AXDA2200DBV3C means that my default VCore voltage is 1.60v right? But my CPU runs at 1.52v at the Auto Vcore voltage and its running fine and stable.

Another thing, is my Tbred B unlocked by default? Cause i tried to connect the last L3 bridge to unlock it, but no different at all. And also tried to change the multiplier without modifying anything at the CPU also cant. Will not POST if i change the multiplier other than Auto.

*BUMP*

Why nobody answer me? All also dont know?

well, most enthusiasts into overclocking have moved from Athlon XP to Athlon 64 and overclocking is completely different on that platform.

I guess that's the reason why people are not quick to reply, as you can see from the 1st post date, I unlocked my Tbred 4 years ago, and although my memory is not yet failing me, I have to admit that I don't know by heart and answer to your question.

my suggestion would be to go for Trial and Error

"is my Tbred B unlocked by default?" well, since you already tried with/without the L3 mod and both came up without success.. I would say that it is locked.

however do note that more recent Athlon XP CPUs have a different top cover and the bridges are hidden, requiring more than just a small layer of paint

So does that means that is no way to unlock a T-bred B? Never heard of people unlocked a T-bred B. :(
