4GB DDR3 / DDR3L 1600MHz SODIMM RAM, Royemai PC3L-12800 2Rx8 1.35V 1.5V CL11 204-pin Notebook Laptop RAM Memory Module

Super easy to swap an replace. My board requires DDR3L only. This works for that too. Very fast. This ram upgrade even unlocked new gaming tiles for play. I'm super impressed with the load times. Grate price an insane value. 16GB of Ram is plenty for almost any game. Unless you want to brake it with exseive mods. Then thus would still need adequate. I really can't believe it's just plug an play. Definitely buy this of your board is lack at DDR3 or DDR3L!

Used to replace a bad memory stick and double my RAM. This old computer is running the best it ever has. The price of these has gone down so much from when I worked in the industry and, with "name brand" systems, sometimes "off brand" memory will not work. I had no problem with this and would recommend for anyone with an old system to repair or upgrade. My computer can now multitask again, even with the new "memory hog" programs that are on the market. Good product at a great price. Recommended

Easy peezy, plug in and works great. Just make sure you order what the computer can use max memory. I read online what it said was the max memory, but they where wrong. After looking at many websites, found it could really only take 8gb. So had to return what a trusted website said the pc could take, installed it and it didn't work. Got the 8gb kit and worked like a charm. Confirm before you order. Should have done this years ago. PC flies now.

I was skeptical given the price of only $12 but I gave it a shot and installed it into an old Sony Vaio laptop I had from 2010. It works perfectly and shows up fine in Windows. I noticed an immediate performance boast going from 4GB to 8GB in this laptop running Windows 10. I have no clue who this manufacturer is but if it works it works.

I needed this for an old Dell Optiplex to increase capacity from 4GB to 8GB. The specs matched what was already installed. I replaced all the ram. It's SK Hynix chips.I tested 3+ passes with memtest. No errors. See attached screenshot.I'm very happy with these, and will buy them again if I need more.UPDATE TO MY PREVIOUS REVIEW:These completed over 5 passes of memtest with no errors and I wrote my positive review. Later I noticed that the system now failed to POST most of the time when cold booting (Rebooting always worked). When this happened, nothing would show on screen and the PC would freeze while showing a diagnostic LED pattern (Screenshot of that code explained in the service manual is attached to this review). Re-seating didn't help. Since there aren't many alternatives in the 1333MHz 2x4GB flavor I decided to to give this brand a second try. The replacement set works great. No more boot issues. Memtest86 completed several passes.I'm removing a star for poor QC. I've learned from experience that it's always necessary to test new RAM. Since this set was defective I wasted more time trying to troubleshoot than I should have.The system I used this in is a Dell Optiplex 990 USFF (i5-2490). The CPU supports 1066/1333MHz ram (9-9-9-24), but will clock down faster RAM if all you can find is 1600Mhz 11CL. The CPU also supports up to 32GB, except the manual says this particular PC and form factor can only support 8GB total (2x4GB). I tried a 16GB 1600MHz kit and things looked good at first, but it would crash after 2 successful passes of memtest. If you have this exact PC, you're probably better off sticking with these RoyeMai/D DUOMEIQI. However if your system can handle more, Teamgroup has a 2x8GB/16GB 1600MHz kit at a lower price.

Worked perfectly in i5 iMac 27” 2011

My 14 year old computer had slowed to where it was almost unusable. Every time Windows upgraded, it got slower. Added this 8 GB upgrade, and it's like having a new machine again. I went from 5 GB of RAM to 12GB, and the difference is night and day. Easy to do, even an old luddite like myself installed the memory upgrade in 10 minutes. My only regret is not doing this a long time ago.

I had an old desktop PC I wanted to upgrade, a Dell XPS Studio 9000. Technically it wanted two matched kits of three sticks, for a total of six, but I couldn't find any matched sets of three or six that weren't overly expensive. I opted for getting three of these duel-kits instead, and so far they have not disappointed. Plopped them in and the system booted right up, 24GB of RAM recognized, all the specs showing exactly as advertised.
