Supermicro H13DSH DDR5 ECC RDIMM Upgrade

This 64GB DDR5 module is built for the Supermicro H13DSH motherboard and delivers registered ECC memory at 4800MHz. It targets administrators who need to expand server capacity with a module that matches the board's population rules and memory-controller expectations.

Sustained Load Behaviour

Registered architecture offloads the memory controller so every populated slot runs at the rated 4800MHz speed under continuous workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running production tasks.

Build and Connector Implications

The 288-pin RDIMM form factor fits only boards wired for registered DIMMs, not UDIMM or SODIMM slots. No heat spreader is fitted, so airflow across the module must come from the chassis design. Verify the manual for supported capacities and DIMM population order before installation.

Questions about this item

How much heat and power does this 1.10 V 64 GB DDR5 RDIMM add when the server runs all day?

Operating at 1.10 V, this DDR5 registered ECC module draws minimal power per DIMM; the registered buffer reduces electrical load on the memory controller, helping keep system thermals manageable during continuous operation.

What motherboard slot and population rules must my Supermicro H13DSH already have free for this 288-pin 2Rx4 kit?

The board needs an available 288-pin DDR5 RDIMM slot and must follow the manual's population order for 2Rx4 registered modules; the kit is spec-matched to the H13DSH memory controller requirements.

Will this CL40 2Rx4 registered ECC kit run at 4800 MT/s alongside older DDR5 modules I might keep in the same chassis?

Mixed-rank or mixed-speed DDR5 populations default to the lowest common speed and timing; for stable 4800 MT/s CL40 operation the H13DSH should use identical 2Rx4 registered ECC DIMMs in the recommended slot order.
