Hi ivwshane. Yes, you will have to unlock that Tbird, unless you are one of the VERY few that got a factory unlocked one to begin with. It comes setup to run at the 100 mhz at default, so the bridges on top have to be closed in order to get it to run at 133 mhz.
I will list a few links here for you to go look at. One is the Hard forum...where there is an awfull lot on unlocking a Duron/Tbird...but finding these threads can be tiresome. I would advise you to look up in the top right of the screen, and click on search. once in the search engine, you can search for a user by user name, or by keyword. In the search by keyword box, type in... unlock amd... You will get a lot of hits, because this topic comes up in many threads...you could set the search engine up to just scan the topic header which would reduce the hits. But, there is a lot of advice at this forum... and some links to actual sites that show you in pic's how to exactly do it. I'll check back here in a day or two and see if you found what you needed. I visit maybe 10 to 20 forums a day, so returning to a particular forum in the same day, sometimes isn't possible...
