Exact-Match Server Upgrade

This 384GB kit delivers eight 48GB DDR5 RDIMM modules rated at 6400 MT/s with CL52 latency and 1.1V operation. The 2Rx8 registered ECC design matches the Supermicro H13SST-G motherboard memory-controller requirements so the system recognises full capacity at rated speed.

Registered ECC Architecture

Registered buffering offloads the memory controller, allowing all eight 288-pin slots to run fully populated without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads.

Sustained Enterprise Stability

The 1.1V operating voltage and major OEM DRAM chips maintain consistent throughput under continuous multi-threaded loads. Population rules and maximum supported capacity vary by platform, so verify the motherboard manual before installation.

Questions about this item

Will eight 48 GB Registered ECC DIMMs reach full 384 GB capacity at the rated 6400 MT/s speed on this motherboard?

The kit is spec-matched to the Supermicro H13SST-G so the memory controller recognises all eight modules at DDR5-6400 with CL52 timings and 1.1 V operation.

How much heat and noise do eight registered DIMMs add when the system runs all day?

These modules have no heat spreader and run at 1.1 V, so thermal load is limited to the DRAM packages themselves; any audible noise comes only from the server chassis fans.

What must the motherboard provide for this 8-module kit to function?

The board needs eight DDR5 288-pin RDIMM slots that support 2Rx8 Registered ECC memory at 1.1 V and the population rules described in the Supermicro H13SST-G manual.
