Four green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM DDR5 6400 CL52 192GB 4x48GB ECC RDIMM Supermicro H14SST-GE

SKU CH-GVNT-6SEDC

192 GB DDR5 server memory kit with four 48 GB registered ECC RDIMMs running at 6400 MHz, CL52 and 1.1 V for the Supermicro H14SST-GE motherboard

  • Total capacity192 GB (4 × 48 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 192 GB total capacity for memory-intensive workloads using four 48 GB modules
  • DDR5-6400 speed with CL52 latency matches the board's rated timing
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operating voltage meets the server's DDR5 power specification
  • Verified fitment for the Supermicro H14SST-GE motherboard with 288-pin RDIMM form factor

Exact-Match Server Upgrade

This 192GB kit delivers four 48GB DDR5 RDIMMs rated at 6400MHz PC5-51200 with CL52 latency at 1.1V. Each module uses a 2Rx8 registered ECC design on a 288-pin form factor built with major OEM chips. It is configured to the precise rank, voltage and timing the Supermicro H14SST-GE memory controller expects.

Suited For And Not Suited For

The kit suits administrators who need the full 192GB capacity recognized at rated speed on the named Supermicro motherboard. It is not for systems that require UDIMM or SODIMM form factors, nor for boards that cannot populate four registered DIMMs at this density. Builders needing non-ECC or unbuffered memory should look elsewhere.

Capacity And Headroom

Four ranks per channel across four slots provide the maximum 192GB this board supports in this configuration, running at the full 6400MHz data rate. Headroom ends when the platform's memory controller reaches its populated-slot limit or when workloads exceed the bandwidth of a single 6400MHz channel.

Questions about this item

Must the Supermicro H14SST-GE motherboard have all 4 DDR5 RDIMM slots free for this 192GB kit?

The kit contains four 48GB modules, so four DDR5 288-pin RDIMM slots are required. Consult the motherboard manual for the approved population order before installing.

Will the registered ECC design of these modules work with any UDIMM memory already installed in the server?

No. Registered RDIMMs and unbuffered UDIMMs cannot be mixed on the same motherboard. Remove any existing UDIMMs before populating with this 4x48GB DDR5 6400 kit.

How can I confirm the kit is running at DDR5 6400 CL52 after installation?

Enter the system BIOS or use a hardware information utility to verify the memory speed shows 6400 MT/s (PC5-51200) and CAS latency reads CL52 at 1.10V.
