Tusl2-c 512mb ram problems

Aug 21, 2001
Hey, i have a tusl2-c motherboard and i am trying to put 512 mb of ram in it, but it will read it as 524 then it will go to windows, then windows will start acting very wierd. I will get blue screens, and sometimes it wont even go into windows. I ran simmtester and the ram tested ok. I also tried different banks and it will still do the same thing. I also went to asus's website and flashed to the latest bios. If you have some recomendations, pls lemme know
