8GB DDR4 2666MHz ECC SODIMM

This A-Tech module delivers 8GB of DDR4 memory at 2666MHz with ECC error correction. It targets microserver, server and workstation laptops that require unbuffered ECC SO-DIMMs. The CL19 latency and 1.20V operation match standard DDR4 specifications for compatible platforms.

260-Pin unbuffered ECC fit

The stick uses the 260-Pin DDR4 SO-DIMM form factor and runs at PC4-21300 speed without a heat spreader. It slots directly into notebooks or microservers that accept unbuffered ECC SODIMMs, freeing a standard non-ECC slot for error-correcting memory where the platform supports it.

Suits ECC-capable microserver laptops

Builders needing ECC protection in a compact SO-DIMM will find this module appropriate. Systems that only accept non-ECC memory, require registered DIMMs, or need capacities beyond a single 8GB stick should look at other options.

Questions sur cet article

How does the CL19 latency affect sustained throughput on this DDR4 2666 ECC SODIMM?

CL19 is the CAS latency at 2666 MHz; it sets the minimum cycle delay for each column access during continuous read or write streams.

What thermal or power behaviour should I expect when this 1.2 V unbuffered ECC module runs all day in a microserver?

The module operates at the standard 1.2 V DDR4 voltage with no heat spreader; power draw stays within JEDEC limits for 8 GB unbuffered ECC SO-DIMMs under sustained load.

Which slot and platform features must my system already provide for this 260-pin ECC SODIMM to function?

A DDR4 SO-DIMM slot wired for ECC unbuffered operation and a memory controller that supports 2666 MHz PC4-21300 with 1Rx8 organisation.
