Exact DDR5-4800 256GB Registered ECC Kit

This 256GB kit contains eight 32GB DDR5-4800 (PC5-38400) registered ECC RDIMMs. Each module runs at 1.1V with CL40 latency and a 2Rx8 organisation. The 288-pin form factor matches the Supermicro H13SST-GC motherboard requirements for full-capacity population.

Suited For Supermicro H13SST-GC Servers

Designed for administrators upgrading a Supermicro H13SST-GC system that demands registered ECC memory at the native DDR5-4800 data rate. Not suitable for workstations or desktops that accept only unbuffered UDIMMs or SODIMM modules.

Registered ECC With 2Rx8 Rank

The registered buffer and on-die ECC let the memory controller drive all eight slots at rated speed while correcting single-bit errors. Systems requiring unbuffered memory or a different rank configuration cannot use this kit.

Questions about this item

What does the DDR5 4800 speed mean once the kit is installed in my Supermicro H13SST-GC?

The modules run at 4800 MT/s with CL40 latency at 1.10 V, so the memory controller recognises the full 256 GB and operates every slot at the rated data rate without downclocking.

How does the 288-pin RDIMM interface and registered ECC design affect what the system can do?

The registered buffer reduces electrical load on the controller, allowing all eight slots to be populated at 32 GB each, while ECC corrects single-bit errors on the fly to prevent silent data corruption.

What physical clearance and slot layout does the 8 x 32 GB kit need on the H13SST-GC motherboard?

Each module is a standard 288-pin DDR5 RDIMM without a heat spreader, so it fits the board's vertical DIMM slots; populate them in the order the manual specifies for eight dual-rank modules.
