16 GB DDR5 ECC SODIMM for laptops and NAS

This module adds 16 GB of DDR5 5200 memory with ECC protection. It targets laptops, all-in-one PCs and NAS units that accept 262-pin SO-DIMMs and require error-correcting code support. The unbuffered design fits standard consumer slots while still providing data-integrity features.

JEDEC and RoHS compliance simplify the upgrade

The stick meets JEDEC standard specifications and is RoHS compliant, so it works as a warranty-safe drop-in replacement. No extra software, heat spreader or configuration utility is bundled; the module relies on the system BIOS to apply its 1.1 V operating voltage and CL42 timings automatically.

ECC unbuffered 262-pin form factor decides fit

The single 1Rx8 rank, 262-pin ECC unbuffered layout is the specification that determines whether the module will be recognised and run at 5200 MT/s. Systems that only support non-ECC or registered DIMMs will not accept this part, and no adapter can change the pin count or buffering type.

Questions about this item

Does the 1Rx8 ECC module need any firmware updates or periodic replacement?

The module is JEDEC-standard DDR5 with no heat spreader, so it requires no firmware updates and has no scheduled replacement interval.

What limits sustained throughput first on this 5200 CL42 stick?

The CL42 latency at 5200 MT/s sets the timing ceiling before bandwidth saturates under continuous load.

How much extra heat or power does the 1.1 V ECC SODIMM add during all-day use?

It runs at the standard 1.1 V DDR5 voltage with no spreader, so thermal output matches baseline JEDEC DDR5 SO-DIMM levels.
