Four green DDR4 RDIMM sticks with black chips, no heat spreaders, 288-pin

NEMIX RAM

NEMIX RAM 128GB (4x32GB) DDR4 3200 PC4-25600 ECC RDIMM THINKMATE

SKU CH-D472-CZX0R

A 128GB kit of four 32GB DDR4 3200 ECC registered RDIMMs validated for Thinkmate servers and workstations

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • 128 GB capacity across four 32 GB modules for large server workloads
  • DDR4 3200 speed rated at PC4-25600 for high-throughput data handling
  • ECC registered RDIMM design detects and corrects memory errors automatically
  • 2 V operating voltage reduces power draw in dense configurations
  • Validated for Thinkmate STX-WS-QS12-12E2 and STX-WS-QE36-14E2 systems

Server-grade capacity for Thinkmate systems

This 128 GB kit delivers four 32 GB DDR4 3200 registered DIMMs built for Thinkmate STX-WS-QS12-12E2 and STX-WS-QE36-14E2 workstations. ECC and registered signalling protect data integrity in multi-socket servers and NAS appliances. The modules run at 1.2 V with CL22 latency. No heat spreaders are fitted.

Quad-channel kit simplifies population

The matched 4 x 32 GB configuration fills all channels on supported Thinkmate boards in one step. Registered 2Rx8 organisation reduces electrical load on the memory controller. Samsung, Micron or Hynix DRAM is used depending on supply. Each module is stress-tested before shipping.

128 GB headroom for virtualisation and ZFS

Four ranks per channel give ample room for large VM fleets, container clusters or deduplicated ZFS pools. Registered ECC RDIMMs scale beyond unbuffered limits without signal degradation. Workloads needing more than 128 GB or faster than DDR4 3200 will require a different platform.

Questions about this item

Will the 2Rx8 registered modules need any firmware updates or periodic replacement?

The 2Rx8 registered DDR4 modules are solid-state with no moving parts or firmware; they do not require scheduled replacement.

What limits sustained throughput first — the CL22 latency or the 3200 MT/s bus?

The 3200 MT/s bus sets the peak bandwidth ceiling; CL22 latency affects response time but does not cap maximum throughput.

How much heat and power does the 1.2 V kit produce when running all day in a Thinkmate server?

Each 32 GB module runs at 1.2 V without a heat spreader; typical DDR4 RDIMM power stays under a few watts per stick, so total heat is low.
