Four green DDR5 RDIMM modules with gold contacts, no heat spreaders

NEMIX RAM

NEMIX RAM 512GB (4×128GB) DDR5 6400 CL52 ECC Registered RDIMM memory upgrade

SKU CH-KE9F-K428E

Four 128 GB DDR5 registered ECC modules totalling 512 GB at 6400 MHz CL52 1.1 V for the Supermicro H14SST-GE motherboard

  • Capacity512GB (4 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 512GB total capacity from four 128GB modules for maximum server density
  • DDR5-6400 speed with CL52 latency delivers rated throughput for Supermicro H14SST-GE
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 1V operation at 2Rx4 rank matches the board's exact electrical requirements
  • 288-pin RDIMM form factor ensures correct physical fit in every supported slot

Exact-Match 512GB Kit

This NEMIX RAM kit delivers 512GB of DDR5 memory in four 128GB Registered ECC RDIMMs. It is built for administrators upgrading a Supermicro H14SST-GE server who need the precise rank, voltage and timing the board expects.

DDR5-6400 CL52 2Rx4 Registered

The modules run at DDR5-6400 (PC5-51200) with CL52 latency at 1.1V in a 2Rx4 organisation. This exact speed, latency, rank structure and registered buffer combination is what the motherboard's memory controller requires to recognise full capacity at rated speed.

For full-population server builds

Suits IT teams populating every slot on a compatible Supermicro platform where registered ECC stability and single-bit error correction are mandatory. Not for workstations or desktops that accept only unbuffered UDIMMs, nor for systems limited to lower capacities or different DDR generations.

Questions about this item

What does DDR5-6400 actually deliver once the kit is installed in the Supermicro H14SST-GE?

The modules run at 6400 MT/s with CL52 timing at 1.1 V, giving the memory controller the exact speed and latency it expects for full-capacity operation.

How does the PC5-51200 rating limit real-world throughput?

PC5-51200 is the standard designation for DDR5-6400; the registered buffer lets the motherboard sustain that data rate across all four slots when fully populated.

What physical clearance does the 288-pin RDIMM kit need in the chassis?

Standard 288-pin RDIMM height with no heat spreader, so it fits any Supermicro H14SST-GE DIMM slot without extra vertical clearance.
