256GB DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 Registered DIMMs rated at 6400MHz with CL52 latency and 1.1V operation. It is built for the Supermicro H13SSL-N motherboard and targets administrators who need maximum registered ECC capacity in every available slot.

Verify DIMM population rules first

Consult the motherboard manual for supported capacities, approved population order, and installation steps before ordering. The board requires 288-pin RDIMM modules; UDIMM or SODIMM variants will not fit or function in this platform.

Registered buffering for full-slot stability

The registered architecture reduces electrical load on the memory controller so all eight slots can run fully populated at rated speed. On-die ECC corrects single-bit errors automatically, and the modules ship without heat spreaders for standard server airflow. Lifetime replacement coverage and US-based technical support are included.

Questions about this item

Does the kit include all eight 32 GB modules or must any DIMMs be purchased separately?

The kit contains eight 32 GB DDR5 6400 CL52 1.1 V registered ECC RDIMMs for a total of 256 GB; nothing else is required to reach that capacity.

Why choose the 256 GB 8 × 32 GB kit instead of a smaller capacity kit?

This 256 GB kit fills all eight slots with 2Rx8 registered ECC modules at the board's rated DDR5 6400 speed, delivering maximum supported capacity in a single validated package.

What does the DDR5 6400 (PC5 51200) rating mean once the modules are installed in the Supermicro H13SSL-N?

The memory controller will recognise the 288-pin RDIMMs at their rated 6400 MT/s with CL52 latency and 1.1 V, running fully populated at full speed without downclocking.
