TECMIYO 16GB Kit (2x8GB) DDR3 / DDR3L 1600MHz UDIMM, PC3-12800 DIMM, PC3 / PC3L-12800U Non ECC Unbuffered 1.35V/1.5V CL11 2RX8 Dual Rank 240 Pin Desktop RAM Computer Memory Module

Needed more memory for the woefully inadequate 4GB configured as "adequate" for Windows, which came in an old LENOVO 7033A2U. As always, the first major version update to Windows rendered it essentially obsolete.The machine is now getting a second life running a real O/S and being used as a UniFi controller. These RAM sticks met the specs at a very reasonable price and have performed as expected with the new O/S and the control software. Installation is standard for this type of RAM, and it has remained stable over the wide range of temperatures in which this machine has to operate.

Installed in a Dell Optiplex 980 and it was recognized right away. No hassles. Good bang for the buck. My video surveillance system which originally had 4gb total, CPU and Memory usage went way down. The system runs faster and is way more responsive.For you non-techies; Check your motherboard specs to see what memory it supports. In my case it was 4gb per slot, 4 slots total. Also you must have a 64 bit operating system and a 64 bit processor or 16gb access won't work, the most you can get from 32 bits is 4gb total. It's best not to mix different memory modules but to use all matched memory modules.

Works perfect in my Synology DS418 play. The perfect upgrade I needed to upgrade the OS and run virtual machine manager.

The headline says it all. It's RAM. It's old-style RAM. It works.Ok, fine. Not only does it work exactly as it's supposed to, but this ram would be perfect for other things. Like "hand-crafted" jewelry you can sell on etsy to all the girls who want to prove they're a 'nerd' as they post their pics to IG from their iPhone.Or my personal favorite, as an add-on to your keychain, so you can advertise to all of the woman around you that you have no intentions of ever entering into a meaningful relationship.I, of course, used this in an old I3 laptop, and it worked with no issues.

The hardest part was finding a video showing how to remove the covers to replace the RAM on my Dell Precision 6800. There are 2 slots under the keyboard and 2 additional slots behind the bottom cover. Took longer to take the covers off than it did to replace the RAM. Booted the computer and 32MB present. No issues.

My aging Optiplex 9020 exhibited the power cycle of death where it keep cycling power without showing the bios screen. After some diagnostics, I determined that it was a bad RAM stick. I can't believe I can find 16GB of RAM for $20, and the pair works. I did some RAM tests after installation to make sure that the entire RAM space is tested - no issues. For $20, even if it lasts a year or so, it would be worth it for me, but I suspect it will last longer, considering how tech and manufacturing have matured. I'm satisfied with this purchase. I generally don't give 5 stars, but this one comes really close; I'll reserve that last star for a revised edit after a few months.

My several-year old Acer Aspire AM3470G-UW10P was lagging badly. I boosted the stock 4GB RAM to 6GB with some RAM I had laying around and the improvement was negligible. I contemplated getting a new computer, but they're (like everything else these days) expensive. I rolled the dice on this 16GB RAM upgrade for $40, (the maximum this PC will accept) and I'm very glad I did. Bootup is still pretty slow because of the programs I have in the background that want to update themselves (antivirus, etc.) and a bunch of networked hard drives, etc., but once it gets fully booted up, it's MUCH faster. No longer do I have to wait forever for my web browser to launch or listen to the 30 second grinding away of my hard drive while I save a photo or a word document. My other PC is a much newer 8-core i5 machine with 24GB ram and an SSD drive, and while this older computer isn't a speed demon like that one, it now holds its' own and keeps up with daily tasks quite well. If you have a quad-core PC that's a few years old with 8 or less GB of memory that's compatible with this RAM, this is a very worthwhile and dirt cheap way to speed it up.
