That's a pretty standard configuration these days; 8 off 4 bit wide chips on one side, 4 off 1 bit wide chips on the other side. 36 bits ( 32 data + 4 parity bits ) total. Only downer is that having chips both sides can make things mechanically tight ! I have yet to see if my next 32 meg of ram will fit in the NT box... > However, I know my other two 8mb simms are parity and >I've heard that mixing and matching isn't a good idea. Depends oin the chipset, but either way, parity is a good thing (TM). J/. -- John Beardmore
