Exact-match server upgrade

This 32 GB DDR5 4800 MHz RDIMM is built for the Supermicro H13DSG-O-CPU motherboard. It delivers the precise 2Rx8 registered ECC configuration the platform expects so every slot can run fully populated at rated speed.

Registered ECC with verified fitment

The module uses a 288-pin registered design with on-die ECC that corrects single-bit errors before they reach the operating system. It matches the board's population rules and 1.1 V requirement so the memory controller recognises the full capacity without manual tuning.

DDR5 4800 standard limits

The PC5-38400 interface caps bandwidth at the JEDEC base rate and CL40 latency is fixed by the specification. Systems needing higher throughput or lower latency must move to a platform that supports faster DDR5 speeds or overclocking profiles not defined by this standard.

Questions about this item

Does the module require any periodic maintenance or component replacement during its service life?

No maintenance is required. The DDR5 RDIMM has no moving parts or user-serviceable components and is covered by a lifetime replacement warranty.

What limits sustained throughput when the DIMM runs continuously at its rated 4800 MT/s speed?

The CL40 latency at 1.10 V and the registered buffer's timing budget set the ceiling for sustained data rates under continuous load.

How much heat and power does a single 32 GB stick produce when the server runs all day?

At 1.10 V the module draws minimal power and runs without a heat spreader, so thermal output stays low even in fully populated configurations.
