ECC SO-DIMM for server laptops

This A-Tech module delivers 16GB of DDR4 2933 memory with error-correcting code in a 260-pin SO-DIMM form factor. It operates at 1.20V with CL21 latency and is built as an unbuffered ECC DIMM for compatible mobile workstations and servers.

Not for non-ECC consumer laptops

Buyers whose systems require standard non-ECC SODIMMs cannot use this module because the extra parity bits will prevent the laptop from posting. Systems limited to lower DDR4 speeds or 1.35V operation should also look elsewhere.

2933 MHz ECC unbuffered spec

The decisive specification is the DDR4 2933 (PC4-23400) ECC unbuffered rating; only platforms that explicitly support this exact speed and ECC type will recognise and use the full 16GB capacity.

Questions about this item

Should I choose the 16GB DDR4 2933 ECC SO-DIMM or a different capacity for my server?

This module provides 16GB in a single 260-pin SO-DIMM; add more identical modules to reach your system's maximum supported capacity.

What does the DDR4 2933 (PC4-23400) speed rating deliver in a real server or workstation?

It runs at 2933 MHz with CL21 latency and 1.20V, giving the rated bandwidth when the platform supports DDR4 2933.

Is this ECC SO-DIMM unbuffered or registered, and what does that limit?

It is an ECC unbuffered SO-DIMM, so it works only in platforms that accept unbuffered ECC memory.
