576GB DDR5 ECC RDIMM kit for Supermicro H14DSG-O-CPU

This 12-module kit delivers 576GB of DDR5 4800 registered ECC memory built to the exact rank, voltage and timing the Supermicro H14DSG-O-CPU memory controller expects. It targets administrators who need maximum supported capacity across all slots for virtualization, database or compute workloads. Each 48GB module is a 2Rx8 registered DIMM so the board recognises the full population at rated speed.

288-pin registered form factor with no heat spreader

The modules use the 288-pin RDIMM form factor this motherboard requires and operate at 1.1V with CL40 latency. Registered buffering offloads the memory controller, allowing every slot to run fully populated while ECC corrects single-bit errors on the fly. The bare PCB design means clearance depends entirely on the server chassis and CPU cooler; verify physical space before installation.

Check motherboard manual for population rules

Supermicro H14DSG-O-CPU memory support varies by BIOS revision and processor configuration, so consult the system manual for approved DIMM population order, maximum capacity per channel and any required firmware updates. The kit includes twelve 48GB modules; confirm your CPU and board combination supports the full 576GB before ordering.

Questions about this item

What DDR5 speed and bandwidth does this 576GB kit deliver on the H14DSG-O-CPU?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, so the memory controller sees the rated speed when all 12 slots are populated.

Which physical slot type and form factor must the motherboard provide for these modules?

The board needs 12 DDR5 288-pin RDIMM slots; the modules are registered ECC 2Rx8 sticks without heat spreaders, so they fit the H14DSG-O-CPU DIMM sockets directly.

What population order does the Supermicro manual require for a full 12-DIMM install?

Consult the H14DSG-O-CPU manual for the approved DIMM population sequence; the kit includes 12 identical 48GB 2Rx8 RDIMMs that must be installed in the exact order the board specifies.
