  • 288-pin RDIMM form factor verified for Supermicro H13SSH-E motherboard

Capacity & Compatibility

This 768 GB kit contains eight 96 GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency. Each module is a 288-pin registered ECC DIMM running at 1.1 V and built with 2Rx4 organisation. The kit is validated for the Supermicro H13SSH-E motherboard.

Suited Builds & Limits

It serves administrators expanding a compatible Supermicro server to maximum supported capacity with registered ECC memory. Buyers needing unbuffered UDIMMs, SODIMMs, non-ECC modules or lower-density kits should look elsewhere.

Build Integration

The registered architecture reduces electrical load on the memory controller when all slots are populated. ECC corrects single-bit errors automatically. Installation must follow the motherboard manual for approved population order and supported capacity limits. No heat spreaders are fitted.

Questions about this item

What motherboard must I already have for this 768GB DDR5 4800 kit to be recognised at full capacity?

You need a Supermicro H13SSH-E motherboard. The kit is an exact-match upgrade validated for that board's memory controller, 288-pin RDIMM slots, and population rules.

Can I keep any existing DDR5 RDIMMs installed while adding these eight 96GB modules?

Only if the board's manual approves mixing 2Rx4 1.10V CL40 modules with other ranks or speeds. Registered ECC architecture helps stability when fully populated, but population order must follow the manual.

How do I confirm the kit is running at DDR5 4800 CL40 after installation?

Check the BIOS memory information or OS tool (dmidecode, CPU-Z) — it should report 4800 MT/s, CAS 40, 1.10 V, and all eight 96GB RDIMMs present for 768GB total.
