Exact-match DDR5-4800 kit for Supermicro H14DSH

This 192 GB kit consists of four 48 GB DDR5-4800 RDIMMs built to the PC5-38400 standard with CL40 timing and 1.1 V operation. It targets administrators who need to populate all available slots on a Supermicro H14DSH motherboard with registered ECC memory that the platform recognises at full capacity and rated speed.

Simple DIMM installation.

Each module uses the standard 288-pin RDIMM form factor and seats in the board's DDR5 slots like any registered DIMM. The critical step is consulting the H14DSH manual for the approved DIMM population sequence; an incorrect slot order will prevent the system from booting or reduce the recognised capacity.

DDR5-4800 bandwidth ceiling

The PC5-38400 interface caps peak transfer rate at the DDR5-4800 specification, so workloads that demand higher memory throughput cannot exceed this limit. Registered buffering adds a cycle of latency versus unbuffered modules, and the fixed 1.1 V operating voltage prevents manual overclocking headroom.

Questions about this item

How can I confirm the kit is running at DDR5-4800 CL40 after installation?

Enter the BIOS or use a tool like CPU-Z and verify the memory frequency reads 4800 MT/s with timings of 40-40-40 and voltage at 1.1 V across all four slots.

What exactly ships in the box and do I need any extra brackets or cables?

The box contains the 192 GB kit as four 48 GB 288-pin DDR5 RDIMMs; no heat spreaders, brackets, cables or additional hardware are included.

My H14DSH manual lists several supported capacities — why choose this 4 x 48 GB 2Rx8 kit?

This 192 GB kit matches the board's qualified 2Rx8 Registered ECC population rule, letting every slot run at the rated 4800 speed without down-clocking or rank-margin issues.
