Server memory kit for Supermicro H14SSL-NT

This 64GB kit contains two 32GB DDR5 RDIMMs rated at 4800 speed with CL40 timing and 1.1V operation. It is built for the Supermicro H14SSL-NT motherboard and provides registered ECC memory for enterprise workloads.

Installation requires registered DIMM slots

The modules use a 288-pin RDIMM form factor that only fits registered memory slots, not UDIMM or SODIMM sockets. Population rules for the H14SSL-NT must be followed exactly or the system will not recognise the full capacity.

Handles multi-socket server loads

Two-rank 2Rx8 organisation lets the memory controller run every slot at rated speed while ECC corrects single-bit errors on the fly. Capacity stops at 64GB with this kit; larger configurations need additional validated modules.

Questions about this item

How can I confirm the kit is running at DDR5-4800 CL40 after installation?

Enter the server BIOS or UEFI and verify the memory speed reads 4800 MT/s with CAS latency 40; the registered ECC RDIMM design ensures the controller recognises both 32 GB modules at the rated 1.1 V.

What exactly ships in the package and is anything else required?

The box contains the 64 GB kit as two 32 GB 288-pin DDR5 RDIMMs; no heat spreaders, cables or additional parts are included and nothing extra is needed for the Supermicro H14SSL-NT.

Why choose this 64 GB 2Rx8 CL40 kit over other capacities or ranks?

This 2 x 32 GB 2Rx8 registered ECC kit matches the H14SSL-NT's qualified voltage of 1.1 V and population rules, delivering full 64 GB capacity at the board's native DDR5-4800 speed.
