8GBx1 + 4GBx2 of DDR3 1600MHz RAM PC3L-12800U-11-13-A1, B1 manufacturer: SK hynix, Dell OEM

I pulled this from an Optiplex 9020 MT that I've used as a case for a sleeper build. This RAM was just fine for the couple weeks I had it running while I was waiting for other parts to come in. Ran Windows 10 and was playing games in 1080p on medium to high depending on the game. (There was also another 4GBx2 of RAM in with it. I'll also be listing that for sale.) The point: it's been tested. No problems with it.
