NEMIX RAM 64GB 1x64GB DDR5 6400MHz CL52 4Rx4 ECC RDIMM Supermicro X14SBM-TF memory upgrade

SKU CH-WMJJ-SVHAA

Adds 64 GB of DDR5 ECC registered memory at 6400 MHz CL52 for Supermicro X14SBM-TF servers

  • Total capacity64 GB
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank4Rx4
  • 64 GB capacity expands server memory headroom for large datasets
  • DDR5 6400 MHz speed accelerates data throughput in AI workloads
  • CL52 latency timing supports responsive operation under heavy load
  • ECC registered design detects and corrects errors for mission-critical stability
  • 10 V operation reduces power draw in dense Supermicro X14SBM-TF deployments

Capacity and platform fit

This 64GB DDR5 module is built for the Supermicro X14SBM-TF server board. The single 4Rx4 registered DIMM delivers ECC protection for workloads that cannot tolerate silent data corruption. It targets administrators upgrading memory density in a supported chassis without mixing ranks.

Sustained-load behaviour

Registered buffering and on-die ECC keep signal integrity stable during long compute runs at 6400MHz. The 1.10V operating voltage limits thermal drift when all ranks are active continuously. CL52 latency is maintained across extended passes because the module is validated under full-load stress testing before shipment.

Installation notes

The 288-pin RDIMM seats in the standard DDR5 slot; no heat spreader means clearance is not a concern. Builders must verify the board's qualified-vendor list for 4Rx4 population rules, as some Supermicro platforms restrict rank-per-channel counts. Mixing this stick with different rank geometries can prevent POST.

Questions about this item

How much heat and power will this 1.10V DDR5 RDIMM generate when running continuously?

At 1.10V the module draws very little power, keeping heat low during all-day server workloads.

What motherboard slot and platform do I need already to install this 288-pin DDR5 ECC RDIMM?

A Supermicro X14SBM-TF board with a free DDR5 RDIMM slot is required for this 64GB kit.

Will this 4Rx4 CL52 DDR5 module work in the same channels as older DDR5 sticks I keep?

It will run at the speed and timing of the slowest installed DDR5 DIMM when mixed in compatible channels.
