I just got a 1800+ today only because it is a ThoroughBred.
When I went to the store today, I picked up a 2100+ but when I looked at the cpu itself I noticed it wasn't a thoroughbred.
So I decided to get a 1800+ instead. The code was AXDA on the cpu itself. So I assured myself it was a tbred.
When I brought it home, I was amazed.
The multiplier WAS unlocked. Right now im running at 166fsb x 10.5. Works like a charm. Only bad part is that my motherboard only support a voltage as high as 1.75v in the bios. Kinda weird. As my Palomino was able to volt up to 1.85v. I'm using a Abit AT7 btw. =(
So far, It's damn fast, compared to my previous Duron 650@870mhz.
The unlocking kit I bought 2 months ago proved useless, as this one is factory unlocked by default ^_^
