Exact DDR5 server upgrade

This 512GB kit delivers four 128GB DDR5 4800MHz RDIMMs built to the Supermicro H13SSW motherboard's exact specifications. Registered ECC operation with CL40 latency and 1.1V voltage ensures full-capacity recognition at rated speed without manual tuning. The 2Rx4 rank structure matches the board's memory controller requirements for stable operation across all populated slots.

For registered ECC workloads only

This memory suits administrators upgrading a Supermicro H13SSW platform that demands registered DIMMs with error correction. Builders needing unbuffered UDIMMs, SODIMM form factors, non-ECC modules, or consumer DDR5 speeds will find this kit incompatible with their hardware. Systems requiring different rank configurations or voltage levels should consult their motherboard documentation before purchasing.

Four-slot registered population

The 288-pin RDIMM form factor installs directly into the H13SSW's DDR5 slots following the manufacturer's population rules for quad-channel operation. Registered buffering reduces electrical load on the memory controller when all slots are filled, while ECC protection maintains data integrity under continuous server workloads. Verify your specific BIOS revision supports this capacity configuration before installation.

Questions about this item

What motherboard must I already own for this 512 GB kit to work?

The kit is built for the Supermicro H13SSW motherboard, matching its 288-pin RDIMM slots and population rules.

Will this 4800 MHz DDR5 kit run at rated speed if I keep older DDR5 modules in the same board?

All slots must use identical DDR5-4800 2Rx4 registered ECC modules; mixing ranks or speeds will force the controller to downclock or disable channels.

How can I confirm the full 512 GB is active and error-free after installation?

Enter the BIOS or run a memory diagnostic; it should show 512 GB detected at 4800 MT/s with ECC enabled and no corrected-error counters incrementing.
