System-Specific DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers a 1TB memory upgrade built from sixteen 64GB DDR5 4800 registered ECC modules. It is designed for administrators and integrators who need to maximise the supported capacity of a Supermicro H14DSG-OD motherboard. The registered architecture allows every slot to run fully populated at rated speed.

2Rx4 Rank and 1.1V Voltage Match

The single specification that determines fitment is the 2Rx4 organisation combined with a 1.10V operating voltage. The Supermicro H14DSG-OD memory controller expects this exact rank structure and voltage; modules with a different rank or voltage will not be recognised at full capacity or at the rated DDR5 4800 speed.

288-Pin RDIMM Form Factor and Population Rules

These 288-pin RDIMMs install directly into the board's DDR5 DIMM slots and require no UDIMM or SODIMM adapters. The kit frees you from mixing capacities or ranks across channels, but you must still consult the motherboard manual for the approved population order and maximum supported capacity per processor before installation.

Questions about this item

What does the CL40 latency mean once this kit is installed in a Supermicro H14DSG-OD server?

CL40 is the CAS latency timing the memory controller uses at DDR5-4800; the kit runs at that rated timing when the board populates all slots per its population rules.

How does the 288-pin RDIMM interface limit speed or capacity on this motherboard?

The 288-pin Registered DDR5 form factor is what the H14DSG-OD requires; it supports the kit's full 1 TB capacity and 4800 MT/s speed when installed in the correct slot order.

What physical space and power does the 16-module kit need to fit in the chassis?

Sixteen 288-pin RDIMMs occupy every DIMM slot on the board and each module draws 1.1 V; verify your chassis has clearance for full-height modules and the PSU can supply the combined load.
