Exact-Match Server Upgrade

This 1.1TB kit contains twelve 96GB DDR5 RDIMMs tuned to 4800 MT/s with CL40 timings at 1.10V. The 2Rx4 registered ECC design matches the Supermicro H13SSL-N memory controller so every slot is recognised at full capacity and rated speed.

Replacing Lower-Capacity Populations

Swapping a partial or mixed-capacity set for this uniform 12-module kit removes rank-mismatch limits and lets the board run all channels fully populated. The jump is worth it when workloads need the full 1.1TB address space without down-clocking or population-rule compromises.

DDR5 RDIMM Platform Limits

Registered DDR5 at 4800 MT/s relies on the motherboard's qualified-vendor list and population rules; unsupported mixes can force lower speeds or disable slots. ECC corrects single-bit errors but cannot fix multi-bit failures, and the 288-pin form factor fits only DDR5 RDIMM slots — not UDIMM or SODIMM sockets.

Questions about this item

Does this 12-module kit use the 288-pin RDIMM form factor required by the Supermicro H13SSL-N?

Yes, every 96 GB module is a 288-pin DDR5 RDIMM, the exact form factor the H13SSL-N memory slots accept.

What is the correct population order when installing all 12 sticks on this motherboard?

Follow the H13SSL-N manual's DIMM population sequence; the board requires a specific slot-filling order for full 1.1 TB recognition.

Will the ECC and registered design of these modules require any firmware updates or ongoing maintenance?

No firmware updates are needed for the ECC registered RDIMMs themselves; they operate at 1.10 V CL40 for the life of the server.
