Server Memory Kit

This 768GB DDR5-6400 registered ECC kit contains twelve 64GB RDIMMs built to the exact rank, voltage and timing the Supermicro H13SSW memory controller expects. It targets administrators who need maximum capacity on that specific motherboard without manual tuning.

Installation Notes

Each 288-pin module seats like any RDIMM, but the board requires a strict population order that the manual defines; skipping a slot or mixing ranks will prevent the system from posting at full capacity. No heat spreaders are fitted, so airflow across the DIMM rows must be adequate.

Pre-Purchase Checks

Confirm the H13SSW revision supports 768GB total and 64GB 2Rx4 registered DIMMs at 1.1V before ordering. Verify the approved slot sequence and any BIOS version minimums in the motherboard documentation to avoid a mismatch.

Questions about this item

How can I confirm the kit is running at DDR5-6400 with CL52 after installation?

Enter the BIOS or UEFI on the Supermicro H13SSW and verify the memory speed shows 6400 MT/s and CAS latency reads 52; the registered ECC design lets the board train all twelve slots at the rated frequency when populated per the manual.

What does the kit contain and is anything else required?

The box holds twelve 64 GB DDR5 288-pin RDIMM modules for a total of 768 GB; no extra parts are needed, but the motherboard manual should be consulted for the correct population order.

Which capacity or speed version should I choose for a fully populated Supermicro H13SSW?

Select this 768 GB kit (12 × 64 GB) at DDR5-6400 CL52 1.1 V 2Rx4 RDIMM; it matches the board's registered ECC requirements and supports full-slot operation at the rated speed.
