Capacity and fit

This 768GB kit contains eight 96GB DDR5 RDIMMs built for the Supermicro H13SSW motherboard. Registered ECC modules with 2Rx4 organization and 1.1V operation match the board's memory controller requirements exactly.

Who this suits and who should look elsewhere

Server builders populating all slots on an H13SSW with the maximum validated capacity will use this kit. Buyers who need a different DIMM count, a lower total capacity, or modules for a motherboard that does not accept 288-pin Registered DDR5 should select another part.

Deciding specification

The 2Rx4 rank structure at DDR5-4800 CL40 determines whether the memory controller can run every slot at full speed without downclocking. If your system documentation requires a different rank per channel or a faster timing grade, this kit will not meet that requirement.

Questions about this item

Will the 1.1V registered DIMMs need any firmware updates or reseating after the first thermal cycle?

The modules are factory-tested at 1.1V and CL40 to match the Supermicro H13SSW memory controller; no firmware updates or reseating are required after initial installation.

What limits sustained throughput when all eight 96GB RDIMMs run at DDR5-4800?

The memory controller's maximum supported frequency of 4800 MT/s and the CL40 latency ceiling are the first bottlenecks under continuous full-population load.

How much extra heat and power does the 768GB kit add when the server runs 24/7?

Each 2Rx4 RDIMM operates at 1.1V without a heat spreader, so total power draw scales with the eight-module population while thermals stay within standard DDR5 registered DIMM limits.
