Server memory upgrade

This 128GB DDR5 4800MHz registered ECC RDIMM is built for the Supermicro H14SHM motherboard. It delivers the exact 2Rx4 rank, 1.1V voltage and CL40 timing the board's memory controller expects for full-capacity recognition at rated speed.

Verified fitment and stability

The 288-pin RDIMM form factor matches the H14SHM's required registered architecture, not a UDIMM or SODIMM. Registered buffering offloads the memory controller so every populated slot runs at full capacity, while on-die ECC corrects single-bit errors to prevent silent data corruption and unplanned reboots.

Check your configuration first

Server memory support varies by model, so consult your system or motherboard manual for supported capacities, approved DIMM population order and installation steps before ordering. This module uses DDR5 technology and will not fit boards designed for other DDR generations.

Questions sur cet article

Will the 2Rx4 registered DIMM layout ever require a firmware or slot-order change as the Supermicro H14SHM ages?

The 2Rx4 registered design follows the board's population rules; any slot-order guidance comes from the motherboard manual, not the memory module itself.

What thermal limit appears first when the 1.1V DDR5 4800 kit runs continuously in a fully populated server?

The modules have no heat spreader, so case airflow must keep the DRAM within JEDEC operating temperature; the first limit is chassis cooling capacity.

How much power does the 128GB DDR5 4800 CL40 kit draw per module during all-day registered ECC operation?

At 1.10 V the registered ECC DIMM draws only the current required for its 4800 MT/s data rate; exact wattage depends on workload and motherboard voltage regulation.
