A-Tech 16GB DDR5 ECC SODIMM

This 16GB DDR5 module runs at 4800 MHz with a CAS latency of 40 and operates at 1.10V. It uses a 262-pin SO-DIMM form factor and features ECC unbuffered 1Rx8 architecture. The memory is built with major brand DRAM IC chips and serves as a compatible replacement for Dell part AC258275SNPCYXXPC/16G. It targets microservers, servers, and workstations requiring error-correcting memory.

Suits ECC microservers and workstations

Builders needing error-correcting DDR5 SO-DIMM memory for compatible Dell microservers or similar platforms will find this module appropriate. It is not for desktop PCs that use standard 288-pin DIMMs or non-ECC consumer memory. Systems requiring registered or buffered DIMMs, higher capacities per slot, or speeds beyond 4800 MHz should look at different memory configurations.

16GB capacity for moderate workloads

The single 16GB rank handles virtualisation, file serving, and multi-tasking workloads within the module's density limit. Workloads demanding more than 16GB per slot or higher memory bandwidth than PC5-38400 provides will exceed this module's headroom. Populating additional slots depends on the host system's maximum supported memory and channel population rules.

Questions about this item

What system slot is needed for this 262-pin DDR5 SO-DIMM?

This module uses the 262-pin DDR5 SO-DIMM form factor and requires a compatible DDR5 SO-DIMM socket.

Can I mix this ECC unbuffered 1Rx8 stick with non-ECC memory already installed?

Mixing ECC and non-ECC modules is not recommended; the system will typically disable ECC or fail to boot when they are combined.

How do I verify the module is running at DDR5 4800 with CL40 after installation?

Check the memory speed and latency in your BIOS or a tool like CPU-Z; it should report 4800 MT/s and CAS latency 40.
