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))

Worked great, no problems. Be sure to place them in the correct slots.

As mentioned on Reddit, the MSI series are not exactly PnP when it comes to XMP clocked RAM - and many spend extra $$$ on the non-Hynix and non-Samsung chip RAM hoping for a bargain to kick up from the DDR4-2666 as shipped. I too, an normally a Crucial customer. But in this case, I heeded the group advice and found this 64GB set CL22 DDR4-3200 PC4-25600 on Hynix silicon. Swapped in, booted up, and presto - 3200MHz RAM! No fuss with over-voltage tweaking or finding the Advanced RAM BIOS parameters that work to get other brands to even show up as 2922 MHz. This just works, and the benches do show a moderate boost in decreased paging, and a little more umph to the shared graphics RAM portion. Worth it? I wouldnt if you havent already been running out of RAM at 32GB, but if you do run the higher RAM consuming stuff, this is your magic silicon that runs full speed at v1.2V.

2 32gb sticks is a lot. I like the fact that they tell you the rank of their product, something others dont, I find that important.

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.

Great value for the money.

I used to product to upgrade an older HP PC from 4GB. My original plan was to replace the 4GB with the 8GB but found that I could install this DRAM in the unused bank and it worked. Total System memory is now 12GB.

Plug and play, no hiccups.

This very specialized memory works perfectly in the machines they were designed for

easy transaction...will definitely use again!

Helped add life to older pc. worked great.
