  • 192 GB total capacity from six 32 GB modules for dense server workloads
  • DDR5-4800 (PC5-38400) speed matches the platform's rated memory controller frequency
  • CL40 CAS latency at 1.1 V delivers JEDEC-standard timing and power efficiency
  • Registered ECC with 2Rx8 organisation corrects single-bit errors and buffers the command bus
  • Verified 288-pin RDIMM fitment for the Supermicro H14DSH motherboard

Exact-match server upgrade

This NEMIX RAM kit delivers 192GB across six 32GB DDR5 4800 RDIMM modules built to the Supermicro H14DSH motherboard specification. Each stick is a registered ECC DIMM with 2Rx8 organisation, CL40 latency and 1.10V operation. The 288-pin form factor matches the board's memory slots exactly.

Suited for full-population ECC configs

The registered architecture and on-die ECC make this kit appropriate for workloads that require error correction and stable operation with every slot filled. Builders who need unbuffered UDIMMs, non-ECC modules, SODIMM form factor or speeds beyond DDR5 4800 should select a different product.

DDR5 4800 registered ECC RDIMM

The single specification that decides fitment is the DDR5 4800 registered ECC RDIMM standard with 2Rx8 rank structure. The Supermicro H14DSH memory controller expects this exact combination of protocol, buffering, error correction and rank geometry; a module that differs in any of those points will not be recognised at full capacity or rated speed.

Questions about this item

Do I need a Supermicro H14DSH motherboard with DDR5 slots to install this 6-module kit?

Yes, this 192GB kit uses 288-pin DDR5 RDIMMs that only fit DDR5 memory slots on the Supermicro H14DSH motherboard.

Will these 2Rx8 Registered modules work if I keep older DDR5 RDIMMs installed in the same server?

Mixing different DDR5 RDIMM kits can prevent the server from booting or force all modules to run at the lowest common speed and timing.

How can I confirm the full 192GB is recognised and running at DDR5-4800 CL40 after installation?

Check the BIOS memory information screen or run a tool like dmidecode to verify total capacity, 4800 MT/s speed, and CL40 latency.
