Exact-Match Server Upgrade

This 128GB kit contains eight 16GB DDR5 4800 RDIMM modules built to the exact rank, voltage and timing the Supermicro H14SSL-N memory controller expects. Each stick runs at 1.1V with CL40 latency and 1Rx8 organisation so the board recognises the full capacity at rated speed.

Registered ECC Build Quality

The 288-pin Registered DIMM form factor matches the slots this motherboard requires, not a UDIMM or SODIMM. Registered architecture buffers the address and command signals so every slot stays stable when fully populated, while on-die ECC corrects single-bit errors before they reach production workloads.

Lifetime Support Bundle

The package delivers the complete 8-module kit ready for installation with no extra cables or software required. Lifetime replacement coverage and free US-based technical support back the upgrade, though builders must still verify their manual for approved population order and maximum supported capacity.

Questions about this item

What DDR5 speed and PC5 rating does this 128GB kit run at?

The kit operates at DDR5 4800 with a PC5-38400 data rate, delivering the exact speed the Supermicro H14SSL-N memory controller expects for full-capacity operation.

What physical form factor and pin count must the motherboard accept for these modules?

Each module is a 288-pin Registered RDIMM; the board must provide DDR5 RDIMM slots, not UDIMM or SODIMM sockets, to fit this kit.

In which order should the eight DIMMs be populated on the Supermicro H14SSL-N to avoid a no-post condition?

Follow the motherboard manual's approved population sequence for eight 1Rx8 Registered DIMMs; skipping the prescribed slot order is the most common cause of boot failure.
