Target Server Upgrade

This 128GB DDR5 RDIMM is built for administrators expanding a Supermicro H13DSG-OM motherboard. The registered ECC design supports fully populated slots at rated speed while correcting single-bit errors to protect production workloads.

Critical Specification Match

The module operates at 5600MHz PC5-44800 with a CL46 latency and 1.1V voltage in a 2Rx4 rank configuration. This exact combination of speed, timing, voltage and rank is required for the memory controller to recognize the full capacity and run without downclocking.

Thermals and Power

Running at the standard 1.10V DDR5 voltage keeps power draw low per module. The lack of a heat spreader means airflow across the bare PCB is necessary to maintain stable temperatures when all slots are populated under sustained load.

Not for non-ECC platforms

Builders using consumer motherboards that accept only unbuffered non-ECC UDIMMs cannot use this registered module; the different pin signalling and command protocol will prevent the system from posting.

Questions about this item

Will the DDR5 5600 speed run at full rate once installed in the Supermicro H13DSG-OM?

The module is an exact-match upgrade specified at DDR5 5600 (PC5-44800) with CL46 timing and 1.10 V, so the memory controller recognises it at full capacity and rated speed.

Does the 288-pin RDIMM form factor and registered ECC design match what the H13DSG-OM motherboard requires?

Yes — this is a 288-pin DDR5 RDIMM with registered (buffered) architecture and ECC, the precise form factor and error-correction the board expects for fully populated slots.

What physical clearance does the module need since it has no heat spreader?

The bare 288-pin RDIMM PCB fits the standard DDR5 DIMM slot height on the H13DSG-OM; verify your chassis or CPU cooler allows the normal module profile before installing.
