Lenovo ThinkSystem ST650 V3 DDR5 Kit

This 256GB kit contains sixteen 16GB DDR5 5600 ECC RDIMM modules built for the Lenovo ThinkSystem ST650 V3 tower server. Registered design and on-die ECC protect data integrity in multi-socket workloads. The kit is sold new and validated for that platform.

288-Pin RDIMM Installation Notes

Modules slot into the server's 288-pin DDR5 RDIMM sockets using standard tool-less levers. Registered buffering adds a clock cycle, so the BIOS must be configured for registered DIMM operation. Mixing registered and unbuffered DIMMs will prevent boot. Populate all sixteen slots identically to keep memory channels balanced.

256GB Registered ECC Capacity

Sixteen ranks of 1Rx8 Samsung, Micron or Hynix die deliver 256GB at 1.1V with CL46 latency. The density suits large virtualisation hosts, in-memory databases and high-thread-count compute nodes. Workloads that exceed 256GB or require load-reduced DIMM signalling will need a different memory topology.

Highlights

  • 256 GB total capacity from 16 matched 16 GB modules
  • DDR5 5600 speed with CL46 latency for responsive server workloads
  • ECC registered design detects and corrects memory errors automatically
  • 1 V operation reduces power draw in dense configurations
  • Validated for Lenovo ThinkSystem ST650 V3 tower server compatibility

Questions about this item

How do I verify the 256GB kit is running at 5600MHz with CL46 after installation?

Enter the system BIOS or UEFI and confirm the memory speed reads 5600MHz and CAS latency shows CL46; the registered ECC modules will also report 1.10V and 1Rx8 organisation.

What is included in the package and do I need any extra parts for the ThinkSystem ST650 V3?

The box contains sixteen 16GB DDR5 288-pin ECC RDIMM modules totalling 256GB; no additional cables, brackets or heat spreaders are required for the ST650 V3.

Which capacity kit should I choose if I want to fill all memory slots on the ST650 V3?

Select the 256GB kit (sixteen 16GB modules) to fully populate the server's DIMM slots with the supported 1Rx8 registered ECC configuration.
