Capacity and Compatibility

This 576GB kit contains twelve 48GB DDR5 modules built for the Supermicro H14DST-F motherboard. Each stick is a 288-pin Registered ECC RDIMM that matches the board's population rules and memory-controller expectations. It is intended for administrators who need the maximum supported capacity in a single validated package.

Registered ECC Advantage

The registered architecture buffers address and command signals so the memory controller can drive all twelve slots at the rated 6400 MT/s without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption that can crash production workloads. This combination replaces unbuffered or non-ECC memory that cannot sustain full-capacity operation on this platform.

DDR5 Platform Limits

DDR5 on this motherboard tops out at 6400 MT/s with CL52 timing at 1.1V, so the kit cannot run faster than the CPU's integrated memory controller allows. Population order and maximum capacity per channel are fixed by the board design; exceeding those limits will prevent boot or force downclocking. Buyers who need higher frequencies or different form factors such as UDIMM or SODIMM cannot use this product.

Questions about this item

Will the 288-pin RDIMM modules fit the DIMM slots on the Supermicro H14DST-F motherboard?

Yes, the 288-pin Registered RDIMM form factor matches the slots this motherboard requires; it is not a UDIMM or SODIMM and is spec-matched to the board's population rules.

What is the correct installation sequence for the 12 modules in the 576GB kit?

Consult the Supermicro H14DST-F manual for the approved DIMM population order; the 12 x 48GB 2Rx8 modules must be installed in the sequence the board specifies to run at the rated 6400 speed.

Do the modules need a heat spreader or active cooling for long-term operation?

The kit ships without a heat spreader; Registered ECC DDR5 at 1.10V is designed to operate within standard server airflow, so no additional cooling is required beyond the chassis fans.
