32 GB DDR5 ECC UDIMM for Lenovo SR250 V3

This 32 GB DDR5 4800 module is built for the Lenovo ThinkSystem SR250 V3 rack server. It delivers ECC unbuffered operation at 1.10 V with CL40 timing in a single 288-pin DIMM. The 2Rx8 organisation suits the platform's memory architecture.

Thermals noise and power draw in normal use

The module runs at the standard DDR5 voltage of 1.10 V without a heat spreader. Passive cooling relies on the server's directed airflow. ECC circuitry adds minimal overhead while protecting data integrity under sustained load.

Upgrade path and when the jump is worth it

Adding this DIMM expands capacity for virtualisation workloads or memory-bound databases on the SR250 V3. The step from a smaller kit is worthwhile when ECC protection and 4800 MT/s throughput become limiting factors for uptime.

Questions about this item

How do I install this 288-pin DDR5 UDIMM in my Lenovo SR250 V3, and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both latches click, then verify in BIOS that the 32GB module runs at 4800 MT/s with ECC enabled.

What maintenance or replacement will this ECC UDIMM need over its service life?

No scheduled maintenance is required; keep airflow clear of the memory slots, run periodic memory diagnostics, and replace the module only if ECC correctable errors accumulate or a diagnostic reports an uncorrectable fault.

What limit appears first when this 1.1V CL40 module runs under sustained load?

The CAS latency of CL40 at 4800 MT/s sets the timing ceiling; sustained throughput is bounded by the DDR5 4800 interface and the dual-rank 2Rx8 organisation.
