4GB Kit (2x2GB) PC2-5300 RAM, DDR2 667MHz SODIMM 2RX8 CL5 1.8V 200pin Memory RAM for Laptop Notebook Computer

good inexpensive ram to boost your PC a little. Have an older PC that couldn't adjust to 8 meg ram so figured I'd just double the current 4 and worked fine with no major adjustments.

Purchased to upgrade an old Asus laptop. Worked like a charm. Very inexpensive way to extend the life of older hardware. Easy to install.

Was exactly what I needed, I took a gamble on this ram not being name brand because I saw a deal and it seems to have paid off. It's working fine so far. Laptop has been used for a day now with this ram and is working well.

installed these relatively easily and noticed an immediate change in speed. raised my fps when gaming too.

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.

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.

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

It worked perfect.
