I have 2 sticks of 8GB micron PC2400 ddr4 memory, UDIMM single rank, NON-ECC. If interested, please see pictures for exact model number. That's 16G total.
RAM prices are ridiculously high nowadays, you might as well go for used memory.
I recently bought a machine and went a little nuts upgrading the ram. If don't need 32g total, so I'm selling half of it. 2 sticks of 8g ddr4 each, made by Micron (you can trust them, not some fly by night manufacturer). No glitzy heat sinks for the gamers, just good solid reliable memory that doesn't run hot.
