1.5 TB DDR5 RDIMM kit for Supermicro H13DSG-O-CPU-D

This kit delivers 1.5 TB of DDR5-4800 registered ECC memory in twelve 128 GB modules. It is built for the Supermicro H13DSG-O-CPU-D motherboard where the memory controller expects 2Rx4 registered DIMMs at 1.1 V. The exact rank, voltage and timing match the board's requirements so the full capacity is recognised at rated speed.

Suited for fully populated server builds needing

This product suits administrators upgrading a Supermicro H13DSG-O-CPU-D to maximum registered ECC capacity with modules that the board's population rules accept. Builders who need unbuffered UDIMMs, SODIMMs or a different voltage should look at other memory types because this kit is registered RDIMM only.

2Rx4 registered ECC at 1.1 V decides fit

The single specification that determines compatibility is the 2Rx4 registered ECC organisation at 1.1 V with CL40 timing. If the motherboard manual calls for a different rank structure, voltage or unbuffered modules, this kit will not function correctly in that system.

Questions about this item

Should I buy the 12-module kit or look for a smaller capacity?

The kit provides 1.5TB total across 12 modules of 128GB each, matching the Supermicro H13DSG-O-CPU-D motherboard's population rules for full-capacity operation.

What does the DDR5 4800 rating deliver once installed?

The modules run at 4800 MT/s with CL40 latency at 1.1V, giving the memory controller the exact timing and voltage it expects for stable, rated-speed performance.

How does the 288-pin RDIMM interface affect real-world use?

Registered buffering offloads the controller so all 12 slots can run fully populated at 4800 MT/s, while ECC corrects single-bit errors to prevent silent data corruption.
