PC3-10600U 8GB Kit (2X4GB) DDR3 10600 1333MHz PC3-10600 4GB 2Rx8 240-pin Dimm CL9 1.5V Desktop RAM Memory Module

I realized my HP Compaq small form factory machine took a max of 16GB Ram, yet I was rolling with only 8, so decided to upgrade. The memory came well packed in these small brown envelopes, and then sealed inside a plastic holder like it is usual for memory sticks. The memory stick were easy to install, the pc recognized it right away, no fault errors. So far the memory sticks work and function well. Compared to the 15 year old ram I had installed in the pc, these memory sticks respond well, and I have not noticed any latency or much heat coming off of them. Caching and using the ram on this pc feels much more stable, and I don't see the RAM picking up as much now under task manager. So far the memory has shown good stability.These 2 pair of 4GB RAM stick are definitely worth the money if you are trying to upgrade some old pc.

I bought this 8GB kit (4x2GB) of Royemai DDR2-667U RAM to upgrade an older desktop, and I’m very impressed. All four sticks were recognized immediately, no errors, and the system runs much smoother now. Perfect fit for my PC2-5300-compatible motherboard.Installation was easy, and the modules feel well-built. If you’re trying to breathe new life into an older machine, this is an excellent and affordable way to do it. Highly recommended for legacy systems still running DDR2!

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

Used in a mini Dell PC that I run Plex on. Plugged right in and was immediately recognized. Working great so far at a nice price.

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.

So after trying different set of this RAM cards, I finally found the one that works perfectly for Late 2013 IMACs. Easy to install and it works like a charm. Be careful if you just receive a card instead of 2. It should be 2 cards for $14,95 NOT 1, so if you get one only, get in contact with amazon and they will send it to you

my Geek Squad installed this and so far, so good. I have an older desktop and this seems to have helped to speed up the slowness. Not ready to get a new model just yet so this is a quick, easy, cheap band-aid! The memory in my system really doubled with these sticks.

5-stars, baby! This RAM brought my under-performing custom 2008 Mountain box back to life again. It now performs as well, or better than, any other computer in my stable. I'm actually shocked at the paramount performance increase, but the benchmarks prove its true. Highly recommended. Will purchase again without reservation!
