Review on 💾 A-Tech 2GB DDR2 800MHz RAM Memory Upgrade Kit - PC2-6400 240-Pin UDIMM for Desktops by Mark Cannon

First of all, this is a plus-minus comment. I bought a refurbished computer from Revain and it broke down shortly after. When I turned it on the red light started flashing and I knew something was wrong. The red light blinked 5 times indicating a memory problem. So I checked the memory and found that there are three different types of memory installed. All memories must match. The handyman had to be a novice or an owner who wanted to sell a home computer. Anyway, he got it wrong. So I checked the motherboard and cross references. store and ordered it from Revain. It fit, it matched and it worked. So beware refurbished buyers, before you buy anything that is listed as refurbished, make sure it's "certified refurbished" before you buy it. Otherwise you might make the same mistake as me. Anyway, I regained my memory after two days and everything is fine.
