Capacity and fit

This 288GB kit contains six 48GB DDR5 ECC Registered RDIMM modules rated at 6400MHz with CL52 latency and 1.1V operation. It is built for the Supermicro H14DSG-O-CPU motherboard where the registered architecture and exact rank, voltage and timing match the board's memory controller requirements.

Pre-installation checks

Verify your system manual for supported capacities, approved DIMM population order and installation steps before ordering. The board requires 288-pin RDIMM form factor, not UDIMM or SODIMM, and memory support varies by model so confirmed compatibility is essential.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly. This prevents silent data corruption and unplanned reboots during continuous server workloads.

Questions about this item

Does the 288GB kit ship as six 48GB modules or do I need to buy extra sticks?

The kit contains six 48GB DDR5 RDIMM modules, giving the full 288GB capacity in a single package.

Should I choose this 288GB 6x48GB kit or a different capacity for the Supermicro H14DSG-O-CPU?

This 6x48GB kit matches the board's 2Rx8 registered ECC specification and 1.1V voltage, so it will be recognised at full speed and capacity.

What does the DDR5 6400 CL52 rating mean once the modules are installed in the server?

The memory runs at 6400 MT/s with a CAS latency of 52 cycles at 1.1V, delivering the rated throughput and error-correcting stability the platform expects.
