    Memory arrived very quickly in pristine brand new condition. Quality and appearance are very good with clear labeling on the DIMMs and a handy troubleshooting card with a support number clearly printed on it. But I never needed the support card, as the DIMMS fit the Dell Optiplex 755 computer perfectly and worked just fine. I find that this ia a good value and easy to justify upgrade for a vintage computer.

    A-Tech 4GB DDR2 kit arrived quickly with excellent packaging. Both 2GB modules work perfectly as described - genuine PC2-6400 800MHz memory tested and running stable. Great value for desktop upgrade. Fast shipping from A-Tech Components with protective anti-static packaging. Reliable performance, highly recommended seller.

    Bought for Sig P365. Works great!! Needs at least an 1.5" belt to fit snugly, have used with 1" belt on dress pants-still works. Wish it had a clip instead of the belt pass through but so not that big a deal. Gonna be watching for diff calibers/brands and will buy again when I spot the one I need.

  • Sooooo worth it to upgrade my computer's memory

    Decided to upgrade the memory in my computer from 4GB to 8GB. After removing the memory modules from my computer to determine the type of memory I needed, and an eBay search, I found these and realized that I could buy 4 - 2GB memory modules for under $36. They perform well and I find that is not unusual for my computer to be using more than the 4GB that my computer came with (I keep Task Manager running constantly on my desktop). My computer slow-downs are no longer evident and it was sooooo worth it to upgrade. Btw, I make my living as a computer technician and I don't know why it took me so long to do this simple (and inexpensive) upgrade to my own computer. Thank you Atech and King Memory!

  • New lease of life

    Certainly made a noticeable difference to pc performance. Eliminated freezes & hanging when running multiple programs, transferring large files & even the startup & shutdown times have seen a big improvement. Made it possible to lessen the load on the main hard drive, so it certainly ticked all the boxes as far as I am concerned. Would recommend to anyone still using a pc with DDR2 memory as a way to breathe new life into your system.
