ok PC3200 ram does run at 400mhz, it must be in your BIOS settings.. if you cannot find any settings in there for bus speed or anything.. maybe there is a BIOS upgrade ... other than that (unless your chip is somehow underclocked) i dunno.
ok, i went into bios and now when i boot up the computer a blue screen comes up and says... something about how a problem has been detected, and windows has been shut down to prevent damage. there is a whole bunch more of stuff. Now this message comes up everytime i boot up the computer. and when i was in BOIS i didnt save any changes. what is the problem?!?!
