The computer came with this single chip: PC2100U 256 DDR CL2.5
I've already bought 1 stick of 512mb 333mhz DDR, 266MHZ compatible, not dual-channel compatible.
Is this compatible with my original ram chip (the 256) or should i just leave the single 512? Windows recognizes the upgrade and counts all 768 megs but i wasnt sure if I would be getting optimal performance with this.
second other possible scenario
I could upgrade the old original single PC2100U 256 stick with a new single stick 256mb, DDR, 400, CL3
so that would be my new 512, 333mhz 2.5 CL2.5
combined with a new 256, 400mhz, CL3
Would this be compatible on this motherboard? and even better than the first scenario?
