I know you can get problems when overclocking with games, but i have had problems with games when not oc'ed like tombraider 4 last revelation crashes instantly and ravenshield still crash's so could it just be their programming??? because ive had other people test these games and they crash on the a64's too.. so i was wondering if anyone else had trouble with older versioned games..... tomb raider 4 wont work but so far i was running deus ex completely fine at 2.5 no crash's... but tomb raider would crash at stock so any suggestions?
