text: i have three slots for ram, a 64mb cam with the unit. redeived 2 /32mb ram,can i install them behind the 64mb? in which order do these rams have to be installed to work properly? in just the way you described. rule of thumb is to always put the largest and most reliable ram in the first slot. then subsequent ram in the next slots. also, its faster speeds when using less ram modules but higher megabytes of ram per ram module stick. im guessing your using win 98 or win me. if using win95, you need to upgrade my friend! thats over a decade old if so. hope this helps. good luck and happy pc'ing! shuuutnstr =o)
