Capacity & Purpose

This kit delivers 1 TB of DDR5 registered ECC memory in eight 128 GB modules for the Supermicro H13DSG-O-CPU motherboard. It targets administrators who must fully populate every slot at the board's rated speed without mixing ranks or voltages.

Registered DDR5 Limits

Registered DDR5 modules buffer address and command signals so the memory controller can drive all eight slots at 4800 MT/s. Unbuffered or SO-DIMM parts will not fit the 288-pin slots and cannot sustain full-capacity operation on this platform.

Exact Configuration Gate

The 2Rx4 organisation, 1.1 V operating voltage and CL40 timing must match the board's qualified-vendor list; any deviation in rank structure, voltage or latency will prevent the system from recognising the full 1 TB at the rated data rate.

Questions about this item

Should I choose the 1TB 8x128GB kit or a different capacity for my Supermicro H13DSG-O-CPU?

The 1TB kit uses eight 128GB modules (2Rx4) to fill all slots at the rated DDR5 4800 speed. Verify your board's maximum supported capacity and population order in the manual before ordering.

What does the DDR5 4800 (PC5-38400) rating deliver once installed in the server?

It runs at 4800 MT/s with CL40 timing at 1.10V, giving the bandwidth and latency the memory controller expects for stable full-capacity operation.

How does the 288-pin RDIMM interface and registered ECC design affect real-world limits?

The registered architecture buffers address and command signals so every slot can run fully populated, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
