Server SO-DIMM for ECC workloads

This 32 GB DDR4 module uses a 260-pin SO-DIMM form factor with ECC and unbuffered signal processing. It is built for servers and workstations that require error correction in a compact laptop-style slot. Buyers needing non-ECC memory or standard DIMM dimensions should look elsewhere.

Dual-rank CL19 at 2666 MHz

The module runs at 2666 MHz with CAS latency 19 and a 19-19-19 timing cycle. Its dual-rank 2Rx8 organisation delivers 32 GB in a single stick, making the rank count and latency the key figures for compatibility checks. Systems that only accept single-rank modules or faster latency bins will not support this part.

Low-voltage operation at 1.20 V

Operating at 1.20 V, the DDR4 SO-DIMM keeps power draw and heat output modest under normal server loads. The thin 145.7 mil profile aids airflow in dense chassis, while RoHS, REACH, WEEE and PFOS certifications confirm compliant materials. No active cooling is required for typical use.

Questions about this item

What does the 2666 MHz speed mean for actual server workloads?

The module runs at DDR4-2666 with CL19 timing, delivering 21333 MB/s peak bandwidth for heavy-duty applications and virtualization tasks.

How does the ECC unbuffered design affect data integrity and latency?

ECC corrects single-bit errors on the fly while the unbuffered signal path keeps latency low at CL19 for responsive server performance.

Will the 260-pin SO-DIMM fit my server's memory slots?

The 2.7-inch long, 1.2-inch wide SO-DIMM uses the standard 260-pin DDR4 layout and 145.7 mil thickness for compatible server boards.
