Exact-match 192 GB DDR5 kit

This 192 GB kit delivers twelve 16 GB DDR5 4800 RDIMM modules built to the Supermicro H13SST-GC memory controller specification. Registered ECC architecture and 1.10 V operation let the board recognise full capacity at rated speed without manual tuning. It targets administrators who need maximum supported density in a single validated package.

Replaces mixed or partial populations

Swapping an incomplete or mixed-rank installation for this 12-module kit removes population-rule conflicts and lets every slot run at 4800 MT/s. The jump is worth it when the workload demands the full 192 GB address space and the server must stay online through firmware updates or DIMM reseating. Buyers who need a different capacity or a UDIMM form factor should look elsewhere.

Sustained-load behaviour

Registered buffering offloads the memory controller so all twelve ranks remain stable during extended compute passes. ECC corrects single-bit errors on the fly, preventing silent corruption during long-running database or virtualization tasks. CL40 latency and 1Rx8 organisation keep throughput consistent without thermal throttling across the full kit.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13SST-GC motherboard slots?

Yes, the kit uses the 288-pin Registered DDR5 form factor required by the H13SST-GC, so every module seats in the standard server DIMM sockets.

What is the correct population order for all 12 modules on the H13SST-GC?

Install the 12x16GB 1Rx8 RDIMMs following the motherboard manual's approved DIMM population sequence to ensure the memory controller recognises the full 192GB at DDR5-4800.

Do the modules need active cooling or thermal pad replacement over time?

No heat spreader is fitted and the modules run at 1.1V; server chassis airflow is sufficient, so no thermal pad maintenance or active cooling is required.
