Two green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM DDR5 6400 128GB 2x64GB CL52 1.1V 2Rx4 ECC Registered RDIMM memory upgrade

SKU CH-V6YN-ZHSTX

A 128 GB DDR5 registered ECC kit of two 64 GB modules running at 6400 MHz CL52 1.1 V for Supermicro H14SHM servers

  • Total capacity128 GB (2 × 64 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 128 GB kit runs at DDR5-6400 speed
  • CL52 latency and 1.1 V voltage for rated performance
  • 2Rx4 registered ECC corrects single-bit errors on the fly
  • 288-pin RDIMM form factor matches Supermicro H14SHM requirements
  • Major OEM Samsung, Micron, Hynix chips ensure enterprise-grade stability

Exact-match DDR5 server upgrade

This 128GB kit contains two 64GB DDR5 6400 RDIMMs built to the precise rank, voltage and timing the Supermicro H14SHM motherboard expects. Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly for enterprise stability.

Installation notes

Modules use the 288-pin RDIMM form factor required by this board; they are not compatible with UDIMM or SODIMM slots. Consult your system manual for the approved DIMM population order before inserting the pair.

Registered ECC requirement

The motherboard only accepts registered ECC RDIMMs, so this 2Rx4 CL52 kit at 1.1V is the correct specification. Systems needing unbuffered or non-ECC memory cannot use these modules.

Questions about this item

How can I confirm the DDR5-6400 CL52 2Rx4 ECC RDIMM kit is running at its rated speed and timings after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 6400 MT/s, CAS latency reads CL52, voltage is set to 1.10V, and the total capacity reports 128 GB across both 64 GB modules.

What exactly is included in the package and do I need any extra parts to install it in a Supermicro H14SHM motherboard?

The box contains the 128 GB kit as two 64 GB 288-pin DDR5 ECC Registered RDIMM modules. No additional components are required for installation on the compatible H14SHM board.

Should I choose this 128 GB 2x64 GB DDR5-6400 CL52 1.1V 2Rx4 ECC RDIMM kit or a different capacity for my Supermicro H14SHM?

Select this 128 GB kit when your workload needs the full 128 GB at DDR5-6400 with registered ECC; choose a smaller kit only if your memory requirements are lower and the motherboard manual confirms the alternative population order.
