Tom: When I began to randomly get the dreaded "blue screen" I tested my old Optiplex 760's memory at startup by pressing the F12 key and, sure enough, there was a memory problem. Rummaging around on the web I found a description of the memory in this machine and did a search on Amazon. A huge number of choices came up but I picked this one based on the reviews about the reliability of the company and the support. It came a day early, was packaged professionally and the information on the package and the leaflet was obviously written by someone who was both knowledgable and proficient in English -- something that is becoming increasingly rare these days when instructions are often incomprehensibly written by a person struggling with a second language. There was a little card enclosed with installation hints, troubleshooting tips, a support number, and a believable promise of satisfaction. The memory installed without a hitch, fit perfectly in the slots in the computer, and worked flawlessly as well as passing the startup diagnostic tests when I ran them. I'll use A-Tech again!

Something goes here.: Bought the 1 GB per stick version:  2GB kit (1GBx2) DDR2 PC2-6400 DESKTOP Memory Modules (240-pin DIMM, 800MHz) Genuine A-Tech Brand

For two sets of 1 GB pairs, the speeds matched, timings matched, and no problems detected through a 24 hour run of Memtest86+ (13 passes total through the 4 GB).

If you're still reading then I suppose you may not know what you're fully getting (in terms of the product itself). A little backstory, DDR2 has been replaced quickly ever since DDR3 came out like 8 years ago. I don't think any manufacturer makes new DDR2 sticks for that reason, especially with DDR4 soon to repeat that history.

Imagine hundreds of thousands of computer towers recycled/scavenged with those DDR2 DIMMs still lying within its chassis. Millions of obsolete sticks in storage boxes. Then for whatever reason, you've now ended up needing DDR2 again because you didn't want to let go of that HP/Dell/Acer/etc tower because "it still worked". It perhaps had 2 or 3 GB inside, and mix and match speeds, might even have been running in Single channel all this time, finally needing to set things right (instead of putting it out to pasture). I had a tower lying...
