I bought an XP-M 2800+ a few months ago, and I now have it in a BioStar socket A mobo and when I boot up everything works fine, except it reads and performs like a 650mhz "unknown" processor... What's wrong and how do I fix it? My friend said something about finding a switch... Is it an actual switch on the mobo or jumpers or what do I need to look for/do to get it running like a 2800+?
