32GB DDR5 ECC SODIMM for microservers

This 32GB DDR5 4800 ECC SODIMM uses Micron chipset components in a 2Rx8 layout. It is built for microserver, server and workstation platforms that require unbuffered error-correcting memory in the 262-pin form factor. Buyers who need registered DIMMs or non-ECC laptop modules cannot use this part.

DDR5 4800 speed and CAS 40 latency

The module runs at DDR5 4800 (PC5-38400) with a CAS latency of 40 at the standard 1.10V. Systems that only support lower DDR5 data rates or different voltage levels will not operate at the rated speed. No heat spreader is fitted, so airflow in dense chassis must be adequate.

2Rx8 rank decides slot population

The dual-rank 2Rx8 organisation determines how many modules each memory channel can accept. Platforms limited to single-rank SODIMMs per channel will not support the full capacity. Verify the system manual for rank limits before ordering.

Questions about this item

Should I pick a single 32GB stick or multiple modules?

This listing is a single 32GB module. Add a second identical stick for dual-channel bandwidth if your board has two slots and supports 2Rx8 density.

What does the 4800MHz rating deliver in a live server?

The module runs at DDR5-4800 with CAS 40 latency at 1.1V, giving PC5-38400 peak throughput when the platform enables that speed.

Does the 262-pin ECC SODIMM need a registered DIMM slot?

No, it is an unbuffered ECC SODIMM (EC4) that fits standard 262-pin DDR5 SO-DIMM slots in microservers and workstations.
