Two green 288-pin DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM DDR5 6400MHz 192GB (2x96GB) CL52 1.1V ECC Registered RDIMM Supermicro H13SSL-NT memory upgrade

SKU CH-1H6X-HXR4R

A 192GB DDR5 ECC Registered RDIMM kit (2x96GB) at 6400MHz CL52, 1.1V, verified for the Supermicro H13SSL-NT motherboard

  • Total capacity192 GB (2 × 96 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 192 GB capacity from two 96 GB modules expands server memory headroom
  • DDR5 6400 speed with CL52 latency delivers rated throughput for H13SSL-NT
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the board's memory-controller specification exactly
  • 288-pin RDIMM form factor fits the Supermicro H13SSL-NT memory slots precisely

Capacity and fitment

This kit supplies 192 GB of DDR5 registered ECC memory in two 96 GB modules built to the PC5-51200 standard. It targets administrators upgrading a Supermicro H13SSL-NT motherboard that requires 288-pin RDIMMs with exact rank, voltage and timing matching.

Who should buy and who should not

It suits operators who need the full 192 GB capacity at the board's native 6400 MT/s speed with CL52 latency and 1.1 V operation. Builders using consumer boards, laptops or any system that accepts only unbuffered UDIMMs or SODIMMs cannot use these modules.

Deciding specification

The registered 2Rx4 organisation combined with on-die ECC is the single attribute that determines whether this kit will initialise at rated capacity and speed on the target platform.

Questions about this item

How do I install the 2Rx4 288-pin DDR5 RDIMMs in the Supermicro H13SSL-NT, and which slot order do people get wrong?

Power down, open the chassis, and insert each 96 GB module into the DIMM slots specified by the Supermicro H13SSL-NT manual for a two-DIMM population; the common error is filling the first two physical slots instead of the board's designated pair for dual-channel operation.

What maintenance or replacement will the 192 GB DDR5 6400 kit need over its service life?

No routine maintenance is required; the modules have no heat spreader and no moving parts, so only a failed DIMM would need replacement under the lifetime warranty.

What limit appears first when the 2Rx4 Registered ECC DDR5 runs sustained workloads at 6400 MT/s?

The memory controller's maximum supported capacity per channel or the board's qualified voltage limit at 1.1 V will be reached before the modules themselves throttle.
