ThinkMate-validated DDR4 ECC RDIMM kit

This 1 TB kit comprises eight 128 GB DDR4 3200 registered DIMMs built for ThinkMate VSX-R5-760S1 and VSX-R5-540RTP workstations. Each module runs at 1.2 V with CL22 latency and 4Rx4 organisation. ECC and registered buffering protect data integrity in multi-socket server workloads.

288-pin RDIMM form factor with major-brand DRAM

Modules use Samsung, Micron or Hynix chips without heat spreaders, fitting standard DDR4 RDIMM slots. Registered signalling reduces electrical load on the memory controller, allowing all eight slots to be populated. The 1.2 V operating voltage matches DDR4 JEDEC baseline for server platforms.

Replaces smaller or slower DDR4 RDIMM sets

Upgrading from lower-capacity or lower-speed registered ECC kits adds 1 TB in a single validated configuration. The jump is worthwhile when workloads exceed current memory bandwidth or capacity limits on compatible ThinkMate systems. Mixed-rank or unbuffered modules are not supported by these platforms.

Questions about this item

Does the DDR4 3200 PC4-25600 interface limit throughput to 25600 MB/s?

The modules run at DDR4 3200 (PC4-25600), so the theoretical peak bandwidth is 25600 MB/s per channel; actual throughput depends on the motherboard and CPU memory controller.

What physical clearance do the 288-pin RDIMM modules need in the ThinkMate VSX-R5-760S1 or VSX-R5-540RTP?

Each module is a standard 288-pin DDR4 RDIMM without a heat spreader, so they fit in the regular DIMM slots of the listed ThinkMate workstations as long as the chassis allows full-height modules.

How are the eight 128 GB sticks installed, and which step is often missed?

Populate all eight slots following the motherboard’s population guide for 4Rx4 registered DIMMs, then enable ECC in the BIOS — the BIOS step is frequently overlooked.
