512GB DDR5-6400 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro H13SST-GC motherboard. Each module runs at 1.1V with CL52 timing and a 2Rx4 organisation. The registered design and on-die ECC give servers the data integrity and full-slot stability that production workloads demand.

288-pin Registered DIMM form factor

The modules use the 288-pin RDIMM form factor this board requires, not UDIMM or SODIMM. Registered buffering offloads the memory controller so all eight slots can be populated at the rated 6400 MT/s speed. Matching the board's population rules lets the system recognise the full 512GB capacity without downclocking or training failures.

Low-voltage DDR5 operation

At 1.1V the kit draws less power per module than higher-voltage DDR5 alternatives, reducing thermal load across a fully populated chassis. The absence of heat spreaders means airflow from standard server fans passes directly over the DRAM packages. ECC correction runs in hardware, adding no software overhead or latency penalty during normal operation.

Questions about this item

Will the eight-module kit stay at DDR5-6400 CL52 when every slot on the Supermicro H13SST-GC is populated?

The 2Rx4 registered ECC design offloads the memory controller so all eight slots can run fully populated at the rated DDR5-6400 CL52 speed without down-clocking.

How much heat and power should I expect from a 512 GB kit running continuously in a dense server chassis?

Each module operates at 1.1 V with no heat spreader, so total power draw is low and airflow from standard server fans is sufficient for continuous operation.

Does the Supermicro H13SST-GC motherboard need a specific CPU or BIOS revision before this 8 × 64 GB kit will be recognised?

The kit is an exact-match upgrade validated for the H13SST-GC; follow the board manual for supported CPU generations, DIMM population order and minimum BIOS version.
