Thanks Speed_Mch2...
the modules have the following markings going Lft to Rht;
PC1600
0050 /2-1
mT /H6V16M8
TG /-8A
PC2100
0110 /2-2
mT /H6V16M8
TG /-7.5
So, what do these tell us....I figure the 8a & 7.5 is the speed, but not much difference there...and the chip count is the same...and only on one side....
btw...do you know what the settings I should have in the bios for this memory....
thanks again....
later...
