OK... I have an older computer I'm working on. It's a Gateway desktop assembled in 2003 (couldn't find the model code). Haven't split open the case but assuming it's 168pin DDR PC2100 DIMM module? I want to drop in a 1GB or 2GB module for the lady. She's doing some pretty memory intensive database work.
It's been a while since I've worked on these things and it seems they have several new varieties of memory now with different pin counts. Could somebody let me know if this sounds like the right memory prescription?
I did a memory upgrade (added two 1GB sticks) to a 5 year old desktop by pulling out 1 existing stick and taking it to MicroCenter. The guys were able to look at it and guide me to the right product. They also did an internet search on my old computer, looked at the board I had in it, and determined that their recommendation would work; and it did.
Under the SPD tab, you should see the memory(type and speed, faster normally works(as long as memory type and pin count match), but on some laptops[never saw this issue with desktops] it can be problematic). I know on some older computers, it may not work, but if all else fails, just pull a stick and read the label.
