  • 48 GB capacity lets you run larger workloads in fewer slots
  • DDR5 4800 speed with CL40 timing delivers rated throughput on the H13DSG-O-CPU
  • Registered ECC design offloads the memory controller and corrects single-bit errors
  • 1 V operation matches the board's voltage requirement for stable full-population runs
  • 288-pin RDIMM form factor fits the exact slot type the motherboard expects

Exact-match DDR5 ECC RDIMM upgrade

This 48GB DDR5 4800 CL40 module is built for the Supermicro H13DSG-O-CPU motherboard. It uses the 288-pin Registered RDIMM form factor that the board requires and runs at the specified 1.10V. The 2Rx8 organisation matches the memory controller expectations so the system recognises the full capacity at rated speed.

48GB capacity with registered architecture

The 48GB module provides substantial headroom for virtualisation, databases and multi-threaded workloads on supported platforms. Registered buffering offloads the memory controller, allowing full-slot population without signal degradation. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

DDR5 4800 PC5-38400 interface limits

The DDR5 4800 (PC5-38400) standard sets the maximum transfer rate and timing envelope for this module. CL40 latency and 1.1V operation are fixed by the JEDEC specification for this speed grade. Population rules, maximum supported capacity per slot and approved DIMM order are defined by the motherboard manual and must be verified before installation.

Questions about this item

Will this 48GB DDR5 4800 CL40 2Rx8 ECC RDIMM work alongside my existing DDR5 modules in the Supermicro H13DSG-O-CPU?

This module runs at DDR5 4800 (PC5-38400) with CL40 latency, 1.1V voltage and 2Rx8 registered ECC. Mixing it with other DDR5 RDIMMs of identical speed, voltage, rank and ECC type is required for stable operation.

How can I verify the 48GB DDR5 4800 module is running at its rated 4800 MT/s and CL40 after installation?

Enter the BIOS or use a tool like dmidecode to confirm the memory reports DDR5 4800 (PC5-38400), CL40 timings, 1.1V and registered ECC status for the installed slot.

Does the package include only the 48GB DDR5 4800 CL40 2Rx8 ECC RDIMM or are cables or brackets also supplied?

The package contains the single 48GB DDR5 4800MHz PC5-38400 2Rx8 1.1V CL40 288-pin ECC Registered RDIMM. No cables, brackets or additional hardware are included.
