Okay so my problem is my new computer (3gb RAM 8800GTS 512mb) I installed windows 32bit business and It only recognises 2.4GB also the RAM should be at 1600MHz and it shows at 1066MHz or something .... ??? So i thought of upgrading to 64bit so it would sort this but then i heard that cod4 (my most played game) and punkbuster on it doesn't work.... ? Anyway round this? i heard something about running it in 32bit, how do i do that?
