For sale is one pair of A-Tech Enterprise Series DDR4 server memory consisting of two 8GB modules, for 16GB total capacity.

I personally purchased these modules new from Amazon on February 3, 2026 for use in my Dell PowerEdge R740xd server.

They are being sold only because I upgraded the server to higher-density memory modules. The RAM was in good working condition when removed and had no known problems. The manufacturer provides a LIFETIME Warranty on this RAM.
