  • 32 GB capacity lets you populate every slot on the Supermicro H14SSL-NT
  • DDR5-4800 speed with CL40 timing matches the board's rated memory controller specification
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 1 V operation at 2Rx8 rank aligns with the motherboard's voltage and population rules
  • 288-pin RDIMM form factor fits the exact slot type the H14SSL-NT requires

Exact-Match DDR5 Server Upgrade

This 32 GB DDR5-4800 Registered ECC RDIMM is built to the precise rank, voltage, and timing the Supermicro H14SSL-NT memory controller expects. It installs as a direct replacement or capacity expansion for that platform. The module uses major OEM chips from Samsung, Micron, or Hynix and carries a CL40 latency at 1.1 V.

Registered Architecture for Full Population

The 288-pin RDIMM form factor matches the board's physical slot and electrical requirements; UDIMM or SODIMM modules will not fit. Registered buffering offloads the memory controller so every supported slot can run fully populated at rated speed, while on-die ECC corrects single-bit errors before they reach the operating system. Consult the motherboard manual for approved population order and maximum capacity per channel before installation.

Lifetime Support and Verified Fitment

The package contains a single 32 GB DDR5 4800 MHz PC5-38400 2Rx8 1.1 V CL40 288-pin ECC RDIMM. NEMIX RAM backs the module with a lifetime replacement warranty and free US-based technical support. Buyers needing unbuffered memory, non-ECC operation, or a different form factor should select an alternative product line.

Questions about this item

Will the CL40 latency hold under sustained 4800 MHz loads?

The module is rated CL40 at 4800 MHz; registered ECC architecture helps maintain rated timings when all slots are populated.

How much heat does the 1.10 V RDIMM produce during continuous operation?

At 1.10 V the DDR5 registered DIMM runs within standard server thermal limits; no heat spreader is fitted.

Does my Supermicro H14SSL-NT need a specific DIMM population order for this 2Rx8 kit?

Yes — consult the motherboard manual for approved population rules and maximum capacity per channel before installing.
