Exact-Match Server Upgrade

This 32GB DDR5 registered ECC RDIMM is built for administrators upgrading an ASRock Rack SIENAD10HM3 motherboard. It delivers the precise 1Rx4 rank, 1.1V voltage and CL40 timing the board's memory controller expects for full-capacity recognition at rated speed.

Registered ECC Architecture

The registered design buffers address and command signals so every slot can run fully populated without overloading the controller, while on-die ECC corrects single-bit errors in flight to prevent silent data corruption and unplanned reboots.

Capacity and Population Limits

A single 32GB module fills one 288-pin slot at DDR5-4800; total system capacity depends on the motherboard's approved population order and maximum supported memory, which must be verified in the system manual before purchase. Buyers needing higher densities per DIMM or non-ECC unbuffered memory for workstation boards cannot use this module.

Highlights

  • DDR5 4800 speed matches controller rated frequency
  • 1Rx4 1.1V CL40 exact spec ensures recognition

Questions about this item

What does the 4800 MHz speed mean once this module is installed in a compatible server?

The module will operate at 4800 MT/s, delivering the rated DDR5 4800 (PC5 38400) data rate when the memory controller supports it.

How does the 288-pin RDIMM interface and registered design affect what the system can do?

The 288-pin RDIMM form factor with registered buffering offloads the memory controller, allowing full-capacity population of every slot at the rated 4800 MT/s speed.

What physical space and slot type does this 288-pin RDIMM need to fit?

It requires a standard DDR5 288-pin RDIMM slot on a motherboard such as the ASRock Rack SIENAD10HM3 and enough vertical clearance for a module without a heat spreader.
