256GB DDR5-5600 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5-5600 registered ECC modules built to the exact timing and voltage the Supermicro H13SST-GC expects. It targets administrators who need full-capacity memory across every slot without manual tuning.

Verified fitment for H13SST-GC

The modules match the board's 288-pin RDIMM requirement and population rules so the memory controller recognises the full 256GB at rated speed. The jump is worth it when replacing slower or smaller DIMMs that limit total capacity or force down-clocking.

Registered ECC for dense population

Registered buffering offloads the controller to keep all eight slots stable at full load while ECC corrects single-bit errors on the fly. The kit needs a compatible Supermicro H13SST-GC motherboard and a chassis with enough DIMM clearance for eight modules.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SST-GC motherboard slots?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor that the H13SST-GC requires; it is not a UDIMM or SODIMM, so it matches the board's physical slot and registered architecture.

What is the correct installation sequence for the eight 32 GB modules on the H13SST-GC?

Populate all eight slots following the motherboard manual's DIMM population order; the registered design allows full-capacity operation when every slot is filled, but skipping the prescribed sequence can prevent the system from recognizing the full 256 GB.

How do I verify long-term reliability of the ECC function on these 2Rx8 modules?

Enable ECC in the BIOS, then monitor the OS or IPMI logs for corrected error counts; the on-die ECC on each 2Rx8 module will automatically fix single-bit errors, and a rising corrected-error counter signals a module that should be replaced.
