System-Specific 576GB DDR5 Kit

This 576GB kit contains twelve 48GB DDR5-4800 RDIMMs built for the Supermicro H13DSG-O-CPU motherboard. It delivers the exact rank, voltage and timing the board's memory controller expects for full-capacity recognition. Registered ECC architecture suits enterprise workloads that demand data integrity across every slot.

DDR5-4800 Registered ECC Limits

DDR5-4800 (PC5-38400) at CL40 and 1.1V sets the speed ceiling for this platform. Registered buffering offloads the memory controller so all twelve slots can run fully populated at rated frequency. ECC corrects single-bit errors on the fly, preventing silent corruption that would otherwise reach production data.

Twelve-Module RDIMM Build

Each 288-pin module uses a 2Rx8 organisation with major OEM chips and no heat spreader, relying on server chassis airflow for cooling. The registered design adds a buffer chip that stabilises signals across the full twelve-DIMM population. Verify your motherboard manual for approved population order and maximum supported capacity before installation.

Questions about this item

Should I choose this 12-module 576GB kit or a smaller capacity for my Supermicro H13DSG-O-CPU?

The kit provides 12 x 48GB modules to fill every slot the H13DSG-O-CPU supports, giving the full 576GB the board can address with registered ECC DDR5.

What does the DDR5-4800 CL40 rating actually deliver once the modules are installed in the server?

The memory controller will run the kit at 4800 MT/s with a CAS latency of 40 cycles at 1.1V, the exact speed and timing the motherboard's qualified vendor list specifies.

How does the 288-pin registered ECC interface affect what the system can do?

The 288-pin RDIMM form factor with registered buffering and ECC lets the H13DSG-O-CPU populate all channels at full capacity while correcting single-bit errors on the fly.
