Exact-match server upgrade

This 128 GB DDR5 5600 RDIMM is built for the Supermicro H14SSL-N motherboard. It arrives as a single 288-pin module with registered ECC, 2Rx4 organisation and a CL46 timing at 1.1 V. The specification matches the board's memory controller expectations so the full capacity is recognised at rated speed.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller when every slot is populated. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.1 V operation keeps power draw predictable across extended workloads.

Replaces slower or smaller kits

It upgrades from lower-capacity DDR5 RDIMMs or slower speed grades that limit total system memory. The jump is worth it when your workload needs the full 128 GB per module at 5600 MT/s with registered ECC stability. It does not fit boards that require UDIMM or SODIMM form factors.

Questions about this item

How much power does each 128 GB DDR5 5600 CL46 2Rx4 ECC RDIMM draw at its rated 1.10 V?

Each module runs at 1.10 V, the standard DDR5 operating voltage, so power draw stays low even when all slots are populated on the Supermicro H14SSL-N.

What motherboard slot and memory type must my system provide for this 288-pin DDR5 RDIMM kit?

The kit needs a DDR5-compatible 288-pin RDIMM slot; the Supermicro H14SSL-N provides exactly that.

Can I mix this 2Rx4 registered ECC DDR5 RDIMM with older DDR5 modules of different rank or speed in the same server?

Mixing ranks or speeds is not recommended; the board's memory controller expects matched 2Rx4 CL46 modules at 5600 MT/s for stable operation.
