Exact-match 512 GB DDR5 kit for Supermicro

This registered ECC RDIMM kit delivers 512 GB across four 128 GB modules running at DDR5 5600 with CL46 latency at 1.10 V. It is built for administrators who need the full capacity the board recognises without manual tuning.

Install by following the board manual population

The 288-pin RDIMM form factor fits only the slots the motherboard specifies for registered memory; mixing with unbuffered DIMMs or skipping the prescribed slot sequence will prevent boot. Verify the exact population rules in the system manual before seating the modules.

Handles full 512 GB at rated speed

Four ranks of 2Rx4 modules keep every channel fully populated at DDR5 5600 while ECC corrects single-bit errors on the fly. Capacity stops at 512 GB; workloads that demand more memory per socket will need a platform that supports larger DIMMs or additional channels.

Questions about this item

How do I verify the kit is running at DDR5 5600 with CL46 after installation?

Enter the system BIOS or use a hardware-monitoring utility such as CPU-Z; the memory tab should show DDR5 5600 (PC5-44800) with timings of 46-46-46 and a DRAM voltage of 1.1 V.

What comes in the box and do I need any extra parts for the Supermicro H14DSG-O-CPU?

The package contains four 128 GB DDR5 288-pin RDIMM modules for a total of 512 GB; no additional brackets, cables or heat spreaders are required for this motherboard.

Should I choose the 512 GB 4 x 128 GB kit or a different capacity for this board?

Select the 512 GB kit when your workload needs maximum registered ECC capacity and the Supermicro H14DSG-O-CPU manual confirms support for four 2Rx4 RDIMMs populated at DDR5 5600.
