ok, "Supports 8/16/32/64/128/256 MB DIMM Module", thats what the 2nd article says. and it seems 2 have the same, or close 2 the same mobo as in my Gateway, and the max in my Gateway is 256MB, soo im guessing that the max in yours is 256MB.
I solved my problem. when i had just the 128 peice, it is a PC-133MHz, the computer would give me the BSOD, so i tried leaving the 64 in there when putting the 128 in. Guess what! No BSOD!! It seems that the 64mb stick slowed down the 128mb stick to 100MHz, so all is well!
