This is a question so dumb I'm embarrassed to ask it. The subject HP is the desktop in one of the water offices I support. It came stock with 4 GB - a single 4 GB module in 1 of the 2 memory slots; the second slot is empty. I want to add an 8 GB module bringing the total RAM to 12 GB. Just drop it in the empty slot. I've done this before (with my own Dell laptop, among others) with no problems.
Wanting to see how to open this case, I hit the YouTube trail. I found a demo of how to install new memory in an HP Pavilion 20. The fellow in the video removed the old memory module, and inserted the new one in the #1 slot, then replaced the original module in the #2 slot. Question arising: is that swap necessary? I would have thought it makes no difference which module is in which slot, so on the principle "if it ain't broke, don't mess with it" I would tend to leave the old module alone and put the new module in the empty slot. I've done that in the past without problems (used to work in a systems house, long ago lost count of how many computers I've assembled from components). So is there something out there that makes it advisable to put the newer (or larger) module in the #1 slot?
Thanks for enlightenment, as always
