Unlocked TBredB 1800+

For reasons unknown my recently arrived AthlonXP TBredB 1800+ seems to have come unlocked. I'm not sure why. Has anyone else found this?

See pictures and more details on my website at http://www.jonpscaife.btinternet.co.uk/techhelp/unlock.html

LOL TbredB comes unlock if you have new mobo like nForce2 or KT400. With KT333 you can only have multi up to 13.

Tbreds

Tbreds are unlocked. The models 2000+ and below are unlocked in just about any board for multiplyers up to 12.5. The models 2100+ and above are unlocked only on boards that can set the multiplyer to 13 or higher and only for that range. There are a few kt400 and nforce2 boards that are able to use any mult on these higher model Tbreds, but not many.
