NEMIX RAM

NEMIX RAM 128GB DDR5 6400MHz 4Rx4 CL52 ECC Registered RDIMM memory upgrade

SKU CH-X3P0-PGKB0

128 GB DDR5 registered ECC RDIMM running at 6400 MHz with CL52 latency and 1.1 V operation for the Supermicro X14SDV-36C-SP3F motherboard

  • Capacity128GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 128GB

  • 128 GB capacity lets you fully populate Supermicro X14SDV-36C-SP3F slots
  • DDR5 6400 speed matches the board's rated PC5-51200 transfer rate
  • Registered ECC architecture corrects single-bit errors to prevent silent data corruption
  • 4Rx4 rank and 1.10 V voltage align with the memory controller's exact requirements
  • 288-pin RDIMM form factor fits the server board's DIMM sockets precisely

Exact-match server upgrade

This 128GB DDR5 RDIMM delivers 6400MHz speed at 1.1V with CL52 timing. The 4Rx4 registered ECC design meets the precise electrical requirements of the Supermicro X14SDV-36C-SP3F motherboard. It installs as a single 288-pin module for immediate capacity recognition.

Replaces slower or smaller RDIMMs

The jump is worthwhile when your current DIMMs run below 6400MHz or total capacity limits virtualization density. Registered buffering allows full-slot population without signal degradation, while ECC corrects single-bit errors that crash unbuffered configurations. This specific rank and voltage combination ensures the memory controller initializes at rated frequency.

Verify motherboard population rules

Consult the Supermicro manual for approved DIMM slot order and maximum supported capacity per channel before ordering. Confirm the board requires 288-pin RDIMMs rather than UDIMM or SODIMM form factors. Ensure your BIOS revision supports 4Rx4 registered modules at the target voltage and frequency.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the Supermicro X14SDV-36C-SP3F motherboard slots?

Yes, the 288-pin Registered DDR5 RDIMM form factor matches the motherboard's DIMM slots exactly; it is not a UDIMM or SODIMM and will seat correctly.

What is the correct installation order when populating all slots with 4Rx4 modules?

Follow the motherboard manual's DIMM population sequence for 4Rx4 Registered ECC modules; the common mistake is filling slots out of order, which can prevent the system from recognising the full 128GB capacity.

Does the module require any firmware updates or ongoing maintenance after installation?

No firmware updates are needed for the memory itself; ensure the motherboard BIOS is current for DDR5 6400 support, and the ECC Registered design handles error correction automatically during operation.
