768GB DDR5 5600 ECC RDIMM kit

This 768GB kit comprises eight 96GB DDR5 5600 CL46 registered ECC RDIMMs built for the Supermicro X14SDW-64C-SP9F motherboard. It delivers the exact rank, voltage and timing the platform expects so the memory controller recognises the full capacity at rated speed. System administrators scaling memory-bound workloads on this specific board will find a validated, drop-in upgrade. Builders using other motherboards or consumer platforms cannot use this registered ECC kit.

Capacity and headroom at 768GB

Eight 96GB dual-rank modules populate every slot the board supports, giving maximum density for virtualisation, in-memory databases or large-scale simulation. The registered architecture buffers each command so the controller drives a fully populated array at 5600 MT/s without signal degradation. Workloads that exceed 768GB or require higher frequencies will need a different platform; this kit cannot scale beyond the board's native limits.

Registered ECC build with 288-pin RDIMM form factor

Modules use major OEM DRAM from Samsung, Micron or Hynix and run at 1.1V without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM keying prevents accidental installation in UDIMM or SODIMM slots, while on-die ECC corrects single-bit errors before they reach the OS. Installation must follow the motherboard manual's population order; no alternative form factors or voltages are supported by this kit.

Questions about this item

Will these DDR5 5600 2Rx4 ECC RDIMMs run alongside any older DDR5 modules I might still have installed?

Mixing modules of different speeds, ranks, or voltages can prevent the server from booting or force all DIMMs to run at the lowest common settings; the board's manual lists the approved population rules for the X14SDW-64C-SP9F.

How can I verify the kit is running at DDR5 5600 CL46 with ECC active after installation?

Enter the BIOS or use a tool such as dmidecode to confirm each 96 GB DIMM shows 5600 MT/s, CL46, 1.1 V, 2Rx4 organisation, and that ECC status reports as enabled and functional.

What exactly ships in the box and is anything else required to complete the 768 GB upgrade?

The package contains eight 96 GB DDR5 5600 CL46 2Rx4 1.1 V 288-pin ECC Registered RDIMMs; no extra cables, brackets, or software are included, and the motherboard must support this capacity and population order.
