Lenovo ThinkSystem ST650 V3 server upgrade

This 128 GB kit contains two 64 GB DDR5 5600 registered ECC RDIMMs built for the Lenovo ThinkSystem ST650 V3 tower server. Each module runs at 1.1 V with CL46 latency and a 4Rx4 organisation. The 288-pin form factor matches the platform's memory slots exactly.

Suited for capacity-bound workloads on this platform

The kit targets administrators expanding memory on a validated Lenovo ThinkSystem ST650 V3 configuration. Systems requiring unbuffered UDIMMs or non-ECC memory cannot use these registered modules. Buyers needing different capacities, speeds or rank layouts should select a kit specified for those requirements.

Registered ECC with 4Rx4 rank layout

The modules implement registered signalling and on-die ECC in a 4Rx4 arrangement at DDR5 5600. This rank density and buffering scheme is the decisive compatibility factor for the target server; mismatched rank counts or unbuffered designs will not function in the qualified slots.

Perguntas sobre este artigo

Should I choose the 128GB kit or a different capacity for my ThinkSystem ST650 V3?

This kit provides 128GB total across two 64GB modules, the only capacity offered for this part number.

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

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, delivering the rated throughput when the platform enables that speed.

Does the 288-pin RDIMM interface limit anything in the ThinkSystem ST650 V3?

The 288-pin DDR5 RDIMM form factor is the native slot type for this server, so the registered ECC modules fit and operate without adapter or downshift.
