32GB ECC SODIMM for microservers and workstations

This 32GB DDR4 module targets microservers, mobile workstations and NAS appliances that require ECC unbuffered SO-DIMM memory. It delivers 32GB in a single 260-pin stick rated at 2933 MHz with CL21 latency. The dual-rank 2Rx8 organisation helps dense memory configurations. Systems must explicitly support ECC SODIMM for the module to function.

Unbuffered ECC design

The stick runs at 1.20V JEDEC standard voltage and uses an unbuffered ECC layout, so it plugs directly into compatible SO-DIMM slots without registered buffering. No heat spreader is fitted, keeping the profile low for tight laptop or 1U chassis bays. Gold-edge contacts on the 260-pin connector ensure reliable seating in vertical or angled sockets.

Low-voltage operation keeps thermals

At 1.2V the module draws minimal power, reducing thermal load inside compact enclosures such as microservers or NAS units. Passive cooling from system airflow is sufficient; no active fan is required on the memory itself. The standard voltage also avoids extra stress on the memory controller during sustained workloads.

Questions about this item

What DDR4 speed and PC4 rating does this 32GB module run at?

This module runs at DDR4 2933 MHz with a PC4-23400 rating, delivering 32GB of ECC unbuffered memory at CL21 latency.

What physical slot and pin count does this SODIMM require?

It uses a standard 260-pin DDR4 SO-DIMM slot; the module has no heat spreader, so it fits slim laptop and microserver bays without extra clearance.

How do I seat this 2Rx8 ECC SODIMM correctly?

Align the notch with the slot key, insert at an angle, then press down firmly until both side clips click; the common mistake is not pushing far enough to engage both clips.
