192GB DDR5-6400 RDIMM kit

This 192GB kit contains twelve 16GB DDR5-6400 registered ECC modules built for the Supermicro H13SSL-NT motherboard. Each DIMM operates at 1.1V with CL52 latency and a 1Rx8 rank structure. The registered design matches the board's memory controller requirements for full-capacity recognition at rated speed.

DDR5-6400 registered ECC limits

DDR5-6400 (PC5-51200) sets the maximum data rate this kit can deliver on the platform. The registered buffer adds one cycle of latency but allows every slot to be populated without signal degradation. ECC corrects single-bit errors on the fly, yet it cannot fix multi-bit failures or replace a sound backup strategy.

288-pin RDIMM build implications

Modules lack heat spreaders, so airflow across the 288-pin connectors must be maintained by the chassis fans. The registered form factor is keyed differently from unbuffered DIMMs, preventing accidental insertion into desktop boards. Population order follows the motherboard manual; incorrect sequencing will halt POST.

Questions about this item

Should I choose the 12 x 16 GB kit or a different capacity for my Supermicro H13SSL-NT?

This kit provides 192 GB across 12 modules of 16 GB each, matching the board's DDR5-6400 RDIMM population rules for full-capacity operation.

What does the DDR5-6400 rating mean once the modules are installed in the server?

The memory controller will run the kit at 6400 MT/s (PC5-51200) with CL52 latency at 1.1 V, delivering the rated throughput when all 12 slots are populated.

How does the 288-pin RDIMM interface and registered ECC design affect real-world use?

The registered buffer reduces electrical load on the memory controller so every slot runs at full speed, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
