Speed 4800MHz

  • 32 GB DDR5 capacity expands server memory headroom for heavy workloads
  • 4800 MT/s speed with CL40 latency delivers rated throughput for Supermicro H13SRH
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 2Rx8 rank organisation and 1.10 V voltage match the board's memory population rules exactly
  • 288-pin RDIMM form factor fits the required slot type without adapters or mismatches

32GB DDR5-4800 RDIMM for Supermicro H13SRH

This 32GB DDR5 4800 CL40 2Rx8 registered ECC module is built for the Supermicro H13SRH motherboard. It runs at 1.1V and uses the 288-pin RDIMM form factor that the board requires. The exact rank, voltage and timing match the memory controller so the system recognises full capacity at rated speed.

Upgrade from lower-capacity or slower DDR5 RDIMMs

Replacing smaller or slower registered ECC DIMMs with this 32GB PC5-38400 module lets you fill more slots at the board's maximum supported frequency. The jump is worth it when your workload needs higher memory density per channel and the registered buffer keeps every populated slot stable.

Suits servers needing validated ECC RDIMM capacity

This module suits administrators expanding a Supermicro H13SRH system with validated registered ECC memory. It is not for desktops or workstations that accept only unbuffered UDIMMs, nor for laptops requiring SODIMMs, nor for any platform that does not support 288-pin DDR5 RDIMMs.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the Supermicro H13SRH motherboard slots?

Yes, the module uses the exact 288-pin Registered DDR5 form factor the H13SRH requires, matching the board's physical slot keying and population rules.

What is the correct installation sequence for this 2Rx8 ECC RDIMM on the H13SRH?

Follow the motherboard manual's DIMM population order; the common mistake is skipping the prescribed slot sequence, which prevents the server from recognising the full 32 GB capacity at 4800 MT/s.

Does this 1.1 V CL40 module require any firmware updates or heat-spreader maintenance over time?

No firmware updates are needed for the memory itself; the module has no heat spreader, so only standard server dust cleaning applies, and ECC continues correcting single-bit errors throughout its service life.
