Exact-match 64 GB DDR5-4800 RDIMM

This 64 GB DDR5 module runs at 4800 MT/s with CL40 timing and 1.1 V operation. It uses a 288-pin registered ECC design built with major OEM chips. The part is validated for the Supermicro H13SSH motherboard and ships as a single DIMM upgrade.

Registered ECC fit for populated slots

The registered architecture buffers address and command signals so the memory controller can drive every slot at rated speed when fully populated. ECC corrects single-bit errors on the fly to prevent silent data corruption. The 2Rx4 rank organisation matches the board's population rules without needing a UDIMM or SODIMM alternative.

Suited for H13SSH capacity expansion

Ideal for administrators adding 64 GB per slot to a Supermicro H13SSH platform that requires registered ECC DDR5. Builders needing unbuffered UDIMMs, non-ECC modules, or a different pin count should look elsewhere. Always confirm supported capacities and slot order in the system manual before installation.

Questions about this item

How does the 2Rx4 registered architecture affect sustained full-capacity operation on the Supermicro H13SSH?

The registered design buffers address and command signals so the memory controller can drive every slot at the rated 4800 MT/s without signal degradation, keeping all 64 GB stable under continuous load.

What are the thermal and power characteristics when this module runs 24/7 at 1.1 V?

Operating at 1.1 V with no heat spreader, the RDIMM relies on server chassis airflow; registered buffering reduces per-pin current draw, so typical power stays within standard DDR5 RDIMM limits for the H13SSH platform.

Which motherboard slot population rules must the Supermicro H13SSH follow for this 288-pin DDR5 RDIMM to be recognised?

The H13SSH manual defines the approved DIMM population order and maximum capacity per channel; follow that sequence exactly so the board detects the full 64 GB at DDR5-4800 CL40.
