128 GB DDR5 ECC UDIMM kit

This kit delivers 128 GB of DDR5 error-correcting memory in four 32 GB unbuffered modules. It is built for the Lenovo ThinkSystem ST250 V3 tower server and suits workloads that require data integrity at standard DDR5 speeds.

DDR5 5600 with CL46 timing

The modules run at DDR5 5600 (PC5-44800) with a CAS latency of 46 and operate at 1.1 V. ECC protection is active, but the memory is unbuffered, so the platform must support unbuffered ECC UDIMMs at this speed and rank configuration.

Check unbuffered ECC support and slot count

Verify that the ThinkSystem ST250 V3 accepts 288-pin DDR5 unbuffered ECC UDIMMs and provides at least four slots for the 2Rx8 modules. Confirm the system BIOS can initialise 128 GB in this configuration before ordering.

Questions about this item

Should I pick the 128GB kit or a smaller capacity?

The kit contains four 32GB modules for 128GB total. Choose it when the Lenovo ThinkSystem ST250 V3 has four free DIMM slots and the workload needs maximum ECC capacity.

What does the 5600MHz speed mean once installed in the server?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V. The server's memory controller will operate them at this rated speed when all four slots are populated.

Does the 288-pin DDR5 ECC UDIMM interface limit anything in practice?

The 288-pin unbuffered ECC UDIMM format fits the ST250 V3's DDR5 slots. It caps memory bandwidth to the PC5-44800 standard and requires a platform that supports unbuffered ECC DDR5.
