Report Problem with adding 1GB of ram to computer in Networking and Hardware Posted December 10, 2006 Okay dude, you really need to try the suggestions here. first, try the 1G stick alone. Does it work? If it doesn't, it's incompatable or bad. Return it to the store, if it does work, then keep it in without the original ram. YOU SHOULD NOT MIX RAM! Espeicially if the RAM is of different speeds. If it's incompatable, perhaps you should take it somewhere to have the ram installed. If your system is capable of PC3200, then it must have a newer celeron or Hyperthreading P4 processor. Yes, PC2700 should work in these computers too, but it will slow everything down.
