64GB DDR4-3200 ECC RDIMM for ThinkMate servers

This single 64GB module delivers registered ECC DDR4 memory at 3200MHz with CL22 latency. It is built for ThinkMate STX-WS-QS12-12E2 and STX-WS-QE36-14E2 workstations and NAS platforms that require 288-pin RDIMM modules. The 4Rx4 organisation and 1.2V operation match the platform specifications.

DDR4-3200 bandwidth and registered buffering

The PC4-25600 interface caps peak throughput at the DDR4-3200 data rate, so workloads that scale beyond this frequency cannot be accelerated by this module. Registered buffering adds one clock cycle of latency but allows the memory controller to drive larger capacities per channel. Systems limited to lower DDR4 speeds will downclock the module automatically.

Major-brand DRAM chips on a bare PCB

Samsung, Micron or Hynix ICs are used without a heat spreader, keeping the module height low for dense server chassis. The 288-pin RDIMM edge connector fits only DDR4 RDIMM slots; it will not seat in UDIMM, SO-DIMM or DDR5 sockets. Buyers needing unbuffered ECC or non-ECC memory for desktop boards cannot use this module.

Questions about this item

Should I pick the 64 GB module or add multiple smaller sticks?

This listing is a single 64 GB RDIMM; adding more modules depends on your ThinkMate chassis slot count and maximum supported capacity.

What does the 3200 MT/s rating deliver inside a ThinkMate workstation?

The module runs at DDR4-3200 (PC4-25600) with CL22 latency, providing the rated bandwidth when the platform memory controller operates at that speed.

How does the 288-pin ECC registered interface affect compatibility?

The 288-pin DDR4 RDIMM uses registered signalling and ECC, so it only works in ThinkMate systems that support registered ECC memory.
