32GB DDR5 ECC SODIMM for microserver upgrades

This 32GB DDR5 5600 module targets microserver and workstation owners who need ECC protection in a compact SO-DIMM form factor. It runs at PC5-44800 speed with CL40 latency and 1.10V operation. The unbuffered 2Rx8 design fits 262-pin slots in compatible IBM-Lenovo platforms.

ECC and validated compatibility change the risk

ECC circuitry detects and corrects single-bit errors to protect data integrity in always-on workloads. The module is tested as a direct replacement for IBM-Lenovo part 4X71N91948, reducing guesswork during installation. Major-brand DRAM ICs and factory QA testing aim to minimise early-life failures.

Unbuffered ECC SO-DIMM dictates platform fit

This module only works in systems that accept unbuffered ECC DDR5 SO-DIMMs at 5600 MT/s. Servers or laptops requiring registered DIMMs, non-ECC memory, or a different pin count will not accept it. Verify your platform’s memory qualification list before ordering.

Questions about this item

Will the 2Rx8 rank configuration require any firmware updates or maintenance down the line?

The 2Rx8 unbuffered ECC module operates at standard 1.10V with no heat spreader; no firmware updates or periodic maintenance are needed for the memory itself.

What is the first limit reached when running the 32GB DDR5-5600 CL40 module continuously at full load?

The CAS latency of 40 at 5600 MT/s sets the timing ceiling; sustained throughput is bound by the DDR5-5600 specification rather than thermal throttling.

How much heat and power does the 1.10V 262-pin SODIMM produce during all-day operation?

At 1.10V the module draws standard DDR5 power and runs without a heat spreader, so temperatures stay within normal SO-DIMM limits for continuous use.
