Timetec 8GB KIT (2x4GB) DDR3 / DDR3L 1333MHz PC3-10600 Non ECC Unbuffered 1.5V / 1.35V CL9 Dual Rank for Dell Optiplex 780 DT/MT/SFF Memory Ram Upgrade and More (Low Density 8GB KIT (2x4GB))

Timetec Hynixs price is reasonable and they work everytime.

Works like a charm!

Straight forward recommendation. Good product. Best price!

Upgraded from 4gig to 8gig and computer is working better.

No complaints from my Win 10 Pro Optiplex 790 Desktop. Started right up. Maxed out the little box at 16 gigs. Its limited by its i3 so its not the fastest, but for above average computer use, this box with maxed out RAM is kicking it pretty good.

I contacted the seller ahead of time to confirm that I was making the right purchase and they directed me to this chip for my system. It works great! Just what I needed to get my PC back up to speed.

Good value

Install was very easy. I went from 4 GB to 7 GB (I just purchased one 4 GB piece). I immediately see an increase with speed. I tested by opening and running as many programs as possible at once. Computer ran great!

I purchased this by searching for Dell optiplex780 but the computer will not accept/recognize it.

Needed to upgrade RAM and was able to find this value. Hesitant at first but read the reviews and was satisfied. Glad to have made this purchase.
