What RAM are you using anyways? I'm gonna guess its PC3200 at least. If you can't run 2-3-3-6 at 200MHz i somewhat doubt your going to run it at 180MHz ither. If its not able to run its spec'd timings for default speeds you should send the RAM back for replacement.
theres my ram, the price was 100 when i bought it and it hasnt dropped, im bummed because i want to pick some more up get 1 gig, but not for that price
