Eight green DDR5 RDIMM modules in anti-static packaging

NEMIX RAM

NEMIX RAM 128GB (8x16GB) DDR5 4800 ECC RDIMM CL40 1.1V THINKMATE SuperServer 421GE-TNRT/TNRT3 memory upgrade

SKU CH-ETRH-FFNWA

Adds 128 GB of DDR5 ECC registered server memory in eight 16 GB modules at 4800 MT/s CL40 1.1 V for ThinkMate SuperServer 421GE-TNRT and 421GE-TNRT3

  • Capacity128GB (8 x 16GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 128 GB total capacity across 8 modules of 16 GB each
  • DDR5 4800 speed rated at PC5-38400 for high throughput
  • ECC registered RDIMM design protects data integrity in servers
  • Low 1.10 V operation reduces power draw and heat
  • CL40 CAS latency with 1Rx8 rank for stable performance

128GB DDR5 4800 ECC RDIMM kit

This 128GB kit contains eight 16GB DDR5 4800 registered DIMMs built for Thinkmate SuperServer 421GE-TNRT and 421GE-TNRT3 systems. It targets IT teams who need ECC-protected capacity for virtualization, databases or heavy compute workloads.

Tool-free DIMM installation with ECC validation

Modules slot into the 288-pin DDR5 RDIMM sockets without tools; the registered buffer reduces electrical load on the memory controller. The main risk is mixing registered and unbuffered DIMMs or populating slots in an order the server firmware does not expect, which prevents POST.

1Rx8 CL40 at 1.10V decides fit

The single-rank 1Rx8 organisation, CL40 latency and 1.10V operating point must match the platform's qualified vendor list; systems that require dual-rank modules, lower latency or a different voltage will not accept this kit.

Questions about this item

How can I confirm the 128GB DDR5 4800 kit is running at CL40 and 1.10V after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 4800 MT/s, CAS latency shows 40 and DRAM voltage is set to 1.10V; the registered ECC modules will also report correctable errors if they occur.

What ships in the box and is anything else required for the ThinkMate SuperServer 421GE-TNRT or TNRT3?

The kit contains eight 16GB 288-pin DDR5 RDIMM modules (1Rx8, Samsung/Micron/Hynix chips, no heat spreaders); no extra parts are needed for the listed SuperServer models.

Why choose this 8×16GB DDR5 4800 ECC RDIMM kit over other capacities for the ThinkMate SuperServer 421GE-TNRT series?

This part number MR38400-618K8 delivers the full 128GB in a single validated kit, ensuring matched 1Rx8 registered modules at 4800 MT/s CL40 1.10V for the ThinkMate SuperServer 421GE-TNRT and TNRT3.
