A-Tech 16GB DDR4 3200MHz ECC SODIMM

This 16GB DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It uses a 260-pin SO-DIMM form factor and includes ECC error correction for data integrity. The unbuffered design suits compatible microserver, server and workstation laptops. It replaces the Hynix HMAA2GS7CJR8N-XN part directly.

Suited for ECC DDR4 SO-DIMM slots

Buyers needing ECC DDR4 SO-DIMM memory for supported microserver or workstation laptops can use this module. Systems that require registered or buffered memory cannot accept this unbuffered stick. Laptops limited to non-ECC memory will not utilise the error-correction feature. Buyers who need capacities beyond 16GB must look elsewhere.

16GB DDR4 3200MHz CL22 ECC unbuffered

The single decisive specification is the 16GB DDR4 3200MHz CL22 ECC unbuffered SO-DIMM configuration. Your system must accept DDR4 SO-DIMM modules with ECC and unbuffered operation at this speed and latency. Verify the motherboard or laptop manual for supported memory specifications before purchase.

Questions about this item

Does my laptop need a 260-pin DDR4 SO-DIMM slot to accept this module?

Yes, the module uses the standard 260-pin DDR4 SO-DIMM form factor, so the system must provide a matching slot.

Can I install this ECC unbuffered SODIMM alongside non-ECC memory already in my system?

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

How can I confirm the module is running at 3200 MT/s with CL22 after installation?

Check the memory speed and latency in the BIOS or with a system-information tool such as CPU-Z to verify 3200 MT/s and CL22 timings.
