Rasalas DDR2 800 PC2-6400 DDR2 4GB Kit (2x2GB) DDR2-800 Udimm Ram Desktop PC2-6400U 2RX8 1.8V CL6 240 Pin Non-ECC Unbuffered Desktop RAM Memory Modules

I bought this for an old Dell desktop optiplex 280, which I still use for legacy windows 2000 software that won't work on newer versions of windows. It had only 2 GB of memory. The BIOS on this machine (and Windows 2000) handle a maximum of of 4 GB of RAM. The motherboard has 4 DIMM slots. I removed the two original 1 GB memory chips and installed these new ones and rebooted. Everything worked fine. I see the 4 GB in the system info and noticed the improvement is processing time significantly. These chips look and fit like origonal items and are reasonably priced. Packaging was excellent.The chips were inside individual sealed plastic chip sleeves then placed in cushined envelope with obvious care.Thanks to Amazon one can still find these legacy electronic items in brand new state. And thanks to the vendor for paying such attention to the packing.One thing to remember is to check your PC documentation for the configuration of the DIMM slots. The chips must be placed in specific order not just in any RAM slot. Also be careful with static discharge that fry the chips without your noticing. At least touch the computer inside metal frame before you work on the chips or wear plastic gloves.

Dislikes, none. These worked perfectly in my antiquated Dell Desktop computer to upgrade it to 4GB from 2GB. Which is it's maximum, since it can't run anything higher than Windows 7.Yes, I can recommend these memory sticks.

I bought these to upgrade the memory in an older desktop I have. An easy swap, and they showed up just fine. The computer is a bit faster now. A good buy for my purposes. I'm not a gamer so I can't speak to that aspect.

The pair of 2gb ddr2 chips work fineWish that had heat sinks

The media could not be loaded. This kit worked perfectly on my Vintage Desktop PC with Intel D945GCCR Motherboard and Intel Pentium D 935 (Dual Core = 3.2 GHz x 2) Processor.
