  • 32 GB dual-channel capacity from two matched 16 GB modules
  • DDR5 4800 speed with CL40 latency for rated server throughput
  • 1 V registered ECC design corrects single-bit errors on the fly
  • 288-pin RDIMM form factor matches Supermicro H13DSG-O-CPU-D slot requirements
  • 1Rx8 rank layout recognised by the memory controller at full population

Exact-match DDR5-4800 RDIMM kit

This 32GB kit contains two 16GB DDR5 ECC Registered DIMMs rated at 4800 MT/s with CL40 latency and 1.1V operation. It is built for the Supermicro H13DSG-O-CPU-D motherboard and matches the board's required 288-pin RDIMM form factor, rank structure and voltage.

Sustained-load stability

Registered buffering reduces electrical load on the memory controller so all populated slots run at the rated 4800 MT/s without downclocking. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during continuous server workloads.

1Rx8 rank configuration

The dual-rank-per-channel 1Rx8 organisation is the specific layout the H13DSG-O-CPU-D memory controller expects for full-capacity recognition. A different rank arrangement would not initialise at the rated speed or capacity.

Questions about this item

How much power does the 1.1 V DDR5 RDIMM kit draw when the server runs continuously?

Each module operates at 1.10 V; total draw depends on the motherboard's memory controller and population, so consult the Supermicro H13DSG-O-CPU-D manual for exact figures.

What motherboard slot and memory type must already be present for this 288-pin RDIMM kit to work?

The Supermicro H13DSG-O-CPU-D must provide DDR5 RDIMM slots; the kit will not fit UDIMM or SODIMM sockets.

Will this CL40 DDR5-4800 kit run at rated speed alongside slower DDR5 modules already installed?

Mixing speeds forces all channels to the slowest module; for full DDR5-4800 performance, populate every slot with matching 4800 MT/s RDIMMs.
