Exact-Match DDR5 RDIMM Kit for Supermicro H13SSW

This 64GB kit contains four 16GB DDR5-6400 Registered ECC modules built to the 1Rx8 rank and 1.1V voltage the Supermicro H13SSW memory controller expects. The 288-pin RDIMM form factor matches the board's slot requirements so the full capacity is recognised at the rated CL52 speed.

Sustained Enterprise Stability

Registered buffering offloads the memory controller, allowing all four slots to run fully populated at DDR5-6400 without signal degradation under continuous load. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during long-running production workloads.

Straightforward Slot Installation

Modules insert vertically into the 288-pin DIMM slots; no heat spreaders mean tight clearance is rarely an issue. The most common mistake is ignoring the motherboard's prescribed population order, so consult the H13SSW manual for the correct slot sequence before seating all four sticks.

Questions about this item

How much power does the 64GB DDR5-6400 kit draw at its rated 1.10V voltage all day?

Each module runs at 1.10V, the standard DDR5 RDIMM voltage, so total draw scales with the four 16GB sticks installed.

What motherboard slot and chipset must I already have for this 288-pin RDIMM kit to work?

You need a Supermicro H13SSW motherboard with 288-pin DDR5 RDIMM slots that accept Registered ECC memory.

Will these CL52 Registered ECC modules run correctly beside older DDR5 RDIMMs I keep in the same server?

They are validated for the H13SSW population rules; mixing ranks or speeds can prevent full-capacity operation, so match the 1Rx8 CL52 spec in every populated slot.
