I have an Acer extensa 560-4020 (also 5620z on the monitor) and have 2 gigs or RAM. I do want more and am told to only put a maximum of 3 gigs because I have a 32 bit system and more than 3 is wasted. Anyway, I've been trying to figure out exactly what I need and seem to come up with serious doubts especially since I want to buy off the net where it can be difficult to return if I buy the wrong thing I believe I need:
ddr2 667 sdram so dimm (dual channel support) - but not sure about how many pins, if it's 5300 or 6700, etc. I tried calling Acer but they are of no help.
Any ideas where I can buy online and what I need specifically?
