384GB DDR5-5600 ECC RDIMM kit

This 12-module kit delivers 384GB of DDR5-5600 registered ECC memory built for the Supermicro H14DSG-O-CPU motherboard. Each 32GB 2Rx8 DIMM runs at 1.1V with CL46 timing and uses the 288-pin RDIMM form factor the board requires. The registered architecture allows every slot to run fully populated at rated speed.

Suited for servers needing maximum registered ECC

Administrators populating all memory channels on a compatible Supermicro platform gain the full 384GB at DDR5-5600 without down-clocking. Builders using consumer UDIMM or SODIMM slots cannot install these modules, and workloads that do not require ECC error correction will not benefit from the registered buffer overhead.

Sustained load stability from registered ECC design

Under continuous operation the registered buffer reduces electrical load on the memory controller so all twelve DIMMs maintain DDR5-5600 throughput. ECC corrects single-bit errors in real time, preventing silent data corruption that can accumulate during long compute runs. The 1.1V operating voltage keeps power draw consistent across the fully populated array.

Questions about this item

Does the Supermicro H14DSG-O-CPU motherboard have twelve DDR5 RDIMM slots so the full 384 GB kit can be installed?

The kit contains twelve 32 GB modules. The H14DSG-O-CPU must provide twelve 288-pin DDR5 RDIMM slots and support 384 GB total capacity for the kit to populate fully.

Can I keep my existing DDR5 4800 RDIMMs and add this DDR5 5600 kit to the same server?

Mixing DDR5 4800 and DDR5 5600 RDIMMs will force all modules to run at the lower 4800 speed and may violate the motherboard's population rules for registered ECC memory.

After installation, how do I confirm the kit runs at DDR5 5600 CL46 1.1 V with ECC active?

Enter the BIOS or use a tool like dmidecode to verify each DIMM shows 5600 MT/s, CL46 timing, 1.1 V operation, registered ECC type and the full 384 GB capacity.
