Two green DDR4 RDIMM modules with gold contacts and black chips

NEMIX RAM

NEMIX RAM 64GB (2x32GB) DDR4 3200 CL22 2Rx8 ECC RDIMM memory upgrade

SKU CH-R9SP-EG6EK

A 64 GB dual-rank DDR4-3200 ECC registered DIMM kit built for Thinkmate TWX tower servers

  • Total capacity64 GB (2 × 32 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • ECC protection prevents data corruption in critical workloads
  • Registered buffering stabilises signal integrity on dense server boards
  • 3200 MT/s throughput matches platform memory bus speed
  • Dual-rank 2Rx8 organisation maximises capacity per DIMM slot
  • 2 V operation reduces power draw under sustained load

Compatible server memory upgrade

This 64 GB kit contains two 32 GB DDR4 registered DIMMs rated at 3200 MT/s with CL22 latency. ECC and register buffering protect data integrity in ThinkMate TWX-XS8 tower servers. Modules run at 1.20 V and use 288-pin RDIMM form factor.

Suited for ThinkMate tower servers.

The kit is validated for ThinkMate TWX-XS8-14S3, TWX-XS8-24S3 and TWX-XS8-24S 3.1 models. Systems that require unbuffered non-ECC UDIMMs or a different pin count cannot use these modules. Builders needing consumer desktop memory should choose a different product.

Registered ECC RDIMM with 2Rx8 organisation

Each module presents a dual-rank 2Rx8 layout using major OEM DRAM from Samsung, Micron or Hynix. The registered interface and error-correcting code are the decisive factors for compatibility with the listed ThinkMate server platforms.

Questions about this item

How do I install the 288-pin DDR4 RDIMM modules in the THINKMATE TWX-XS8 tower and which slot order is correct?

Power down the server, open the chassis, align each 288-pin DDR4 RDIMM with the keyed slot, press firmly until the retention clips click, then follow the THINKMATE manual for the prescribed population sequence.

Will the ECC registered DIMMs require any firmware updates or periodic reseating during their service life?

No scheduled firmware updates or reseating are needed; the modules run at 1.20 V with on-die ECC and registered buffering, so they operate maintenance-free once correctly seated.

At what point does the CL22 latency become the bottleneck during sustained heavy workloads?

Under continuous load the CAS latency of 22 cycles at 3200 MT/s is the first timing constraint encountered, limiting random-access throughput before bandwidth or thermal limits appear.
