  • 256 GB total capacity lets you fully populate four slots for maximum server memory headroom
  • DDR5-5600 speed with CL46 latency delivers the exact data rate your controller expects
  • Registered ECC architecture corrects single-bit errors on the fly to prevent silent data corruption
  • 1 V operating voltage matches the motherboard specification for stable full-capacity operation
  • 288-pin RDIMM form factor fits the Supermicro H13SST-GC slots without adapters or mismatches

Exact-fit DDR5 kit

This 256GB kit delivers four 64GB DDR5 5600 RDIMMs tuned to CL46 at 1.1V. It targets administrators upgrading a Supermicro H13SST-GC motherboard that requires registered ECC memory in a 288-pin form factor.

Registered ECC limits

Registered buffering lets every slot run fully populated at the rated 5600 MT/s, while on-die ECC corrects single-bit errors before they reach the OS. The motherboard’s own population rules still dictate maximum capacity and slot order.

No-spreader daily use

Modules ship without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots, so installation follows the board’s documented sequence.

Questions about this item

Should I pick the 256GB kit or a smaller capacity for my Supermicro H13SST-GC?

The 256GB kit provides four 64GB RDIMMs that match the board's 2Rx4 population rules; choose it when you need the maximum supported capacity in a single validated kit.

What does DDR5 5600 mean for actual throughput in this server?

The modules run at 5600 MT/s, delivering up to 44800 MB/s of peak bandwidth per channel when the memory controller is fully populated with all four DIMMs.

How does the 288-pin RDIMM interface limit speed or capacity on this motherboard?

The registered 288-pin DDR5 RDIMM form factor lets the H13SST-GC run all four slots at the rated 5600 speed without downclocking, while ECC and registered buffering maintain stability at the full 256GB capacity.
