NEMIX RAM 512GB DDR5-4800 ECC RDIMM Kit

This 512GB kit contains eight 64GB DDR5-4800 registered ECC RDIMMs built for the Supermicro H13DSG-O-CPU-D motherboard. The modules run at 1.1V with CL40 latency and a 2Rx4 rank structure. Registered buffering allows full population across all slots while ECC corrects single-bit errors. It is designed for servers that require exact spec-matching to the board's memory controller.

Suited for H13DSG-O-CPU-D upgrades, not for desktops

Administrators expanding a Supermicro H13DSG-O-CPU-D system to 512GB with validated DDR5 RDIMMs will find the correct voltage, rank, and timing in this kit. Builders using consumer motherboards, workstations needing UDIMMs, or laptops requiring SODIMMs cannot use these modules. Systems limited to lower maximum capacities or different DDR generations should look elsewhere.

2Rx4 rank decides full-capacity recognition

The 2Rx4 organisation is the single specification that determines whether the memory controller recognises all 512GB at the rated DDR5-4800 speed. A different rank configuration would prevent full population or force a lower data rate. Verify the motherboard manual for approved DIMM population order before installing.

Questions about this item

How can I confirm the 512GB kit is running at DDR5-4800 CL40 1.10V after installation?

Enter the BIOS or UEFI and verify the memory speed shows 4800 MT/s, CAS latency reads 40, and voltage is set to 1.10V; the registered ECC RDIMM design ensures the Supermicro H13DSG-O-CPU-D recognises all eight 64GB modules at full capacity.

What exactly ships in the box and do I need any extra parts?

The package contains the complete 512GB kit — eight 64GB DDR5-4800 2Rx4 288-pin ECC registered RDIMMs — no heat spreaders or additional cables are included or required for installation in the compatible Supermicro motherboard.

Why choose this 8×64GB 2Rx4 CL40 kit over other capacities or ranks?

This exact-match kit delivers the full 512GB the H13DSG-O-CPU-D supports, uses the 2Rx4 organisation and CL40 timing the board's memory controller expects, and runs at the specified 1.10V so every slot operates at rated DDR5-4800 speed when fully populated.
