576GB DDR5-6400 ECC RDIMM kit

This 576GB kit contains six 96GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro H14DSG-O-CPU motherboard. Each module runs at 1.1V with CL52 latency and a 2Rx4 organisation, matching the board's memory controller expectations for full-capacity recognition and rated-speed operation.

Suits servers needing maximum registered ECC

The Registered (buffered) architecture offloads the memory controller so all slots stay stable when fully populated, while ECC corrects single-bit errors on the fly. This kit is not for systems that require unbuffered UDIMMs, SODIMM form factors, non-ECC memory, or lower-density modules that the board's population rules do not support.

576GB total across six 96GB DIMMs

The kit fills six slots with 96GB each, delivering the full 576GB at DDR5-6400 (PC5-51200). Capacity headroom ends when the motherboard's maximum supported memory per slot or total population limit is reached; consult the system manual for exact population order and approved configurations before installation.

Questions about this item

My Supermicro H14DSG-O-CPU motherboard only has 8 DDR5 slots — will this 6-module 576 GB kit leave room for future expansion?

Yes, the kit uses six 288-pin RDIMM modules, leaving two slots free on an 8-slot board. Follow the manual's population order to keep all channels balanced and allow adding matched modules later.

Can I mix these 6400 CL52 1.1 V RDIMMs with slower DDR5 ECC modules already installed in my server?

The board will downclock every module to the slowest speed and loosest latency present. For stable operation at the rated 6400 MT/s and CL52, populate all channels with identical 1.1 V registered DIMMs.

After installing the 6x96 GB kit, how can I verify the server sees the full 576 GB at DDR5-6400 with ECC active?

Check the BIOS memory information screen or run dmidecode / lshw on Linux; both will show 576 GB total, 6400 MT/s data rate, registered ECC type, and 1.1 V operating voltage.
