Sixteen bare green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 1TB 16x64GB DDR5 4800 CL40 2Rx4 ECC RDIMM ThinkMate memory upgrade

SKU CH-3H5V-XE1ZG

16 registered ECC DDR5 modules totalling 1TB at 4800MHz CL40 for ThinkMate tower servers

  • Total capacity1 TB (16 × 64 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 1TB total capacity across 16 modules of 64GB each
  • DDR5 4800 speed rated at PC5-38400 for server workloads
  • ECC registered design with 2Rx4 rank for data integrity
  • Low 1.10V operating voltage reduces power draw
  • Validated for ThinkMate TWX-XS8 tower server compatibility

ThinkMate Tower Server Memory Kit

This 1 TB kit contains sixteen 64 GB DDR5 4800 registered DIMMs built for ThinkMate TWX-XS8-24S4 and TWX-XS8-14S4 tower servers. ECC and 2Rx4 organisation protect data integrity in mission-critical workloads. The modules operate at 1.1 V without heat spreaders.

DDR5 4800 Registered ECC Limits

Registered signalling adds a clock cycle of buffering so the memory controller drives many ranks reliably. CL40 latency and the PC5-38400 data rate define the ceiling for single-thread throughput. Unbuffered or non-ECC modules cannot be mixed with this kit.

1 TB Capacity and Headroom

Sixteen slots filled with 64 GB modules deliver the maximum supported density for the qualified platforms. Virtualisation hosts and in-memory databases gain ample headroom for concurrent VMs or large datasets. Workloads needing more than 1 TB must move to a platform with additional memory channels.

Questions about this item

Should I pick the 16-module 1TB kit or a smaller capacity for my ThinkMate tower?

The 16 x 64GB kit fills all slots on supported ThinkMate TWX-XS8-24S4 and TWX-XS8-14S4 towers, delivering the maximum 1TB registered ECC capacity in a single matched set.

What does DDR5 4800 CL40 mean for real-world server throughput?

The modules run at 4800 MT/s with CAS latency 40, providing PC5-38400 bandwidth for multi-threaded workloads on compatible ThinkMate platforms.

Does the 288-pin RDIMM interface limit speed or capacity on these ThinkMate servers?

The 288-pin DDR5 RDIMM form factor with 2Rx4 organisation and registered buffering is the native interface for the listed ThinkMate towers, enabling full 4800 MT/s operation across all 16 slots.
