Server-grade capacity kit

This 512GB kit consists of eight 64GB DDR5 modules built to the PC5-44800 standard at 5600 MT/s with CL46 latency and 1.10V operation. The 2Rx4 Registered ECC RDIMM design matches the exact rank, voltage and timing the Supermicro H13SSH memory controller expects for full-capacity recognition. It is intended for administrators upgrading that specific platform.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot runs fully populated at the rated 5600 MT/s without downclocking under continuous demand. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long-running workloads. The 1.10V baseline keeps power draw predictable across extended sessions.

DDR5 interface limits

DDR5 at 5600 MT/s delivers the bandwidth ceiling defined by the PC5-44800 specification; higher speeds are not supported by this kit. The 288-pin RDIMM form factor fits only boards wired for registered DDR5, not UDIMM or SODIMM slots. Builders needing more than 512GB or a different DIMM type must choose another solution.

Questions about this item

How much power does the 1.1V DDR5 kit draw when the H13SSH runs all day fully populated?

Each 64 GB module operates at 1.10 V; total system draw depends on CPU load and the board's VRM efficiency, so consult the H13SSH manual for platform-level figures.

What must the server already have for this 288-pin RDIMM kit to be recognised?

A Supermicro H13SSH motherboard with a DDR5-capable CPU, all eight DIMM slots free, and BIOS updated to the version that supports 512 GB of 2Rx4 registered ECC memory.

Will the registered ECC design keep older storage controllers stable when the H13SSH is fully loaded?

Registered buffering reduces electrical load on the memory controller and ECC corrects single-bit errors, helping prevent silent data corruption on attached controllers during sustained workloads.
