Server-Ready Memory Kit

This 384GB kit contains six 64GB DDR5 Registered DIMMs built for the Supermicro H14DSH motherboard. It targets administrators who need maximum capacity across every available slot in a validated configuration.

Registered ECC Architecture

The 2Rx4 Registered design buffers address and command signals so the memory controller remains stable when all channels are fully populated. ECC corrects single-bit errors on the fly to prevent silent data corruption in production workloads.

Exact-Fit Validation

Modules are tested against the H14DSH population rules so the kit is recognised at full capacity and rated speed without manual tuning. No heat spreaders are included, matching the board's standard airflow expectations.

Questions about this item

What does the 4800 MHz rating mean once the kit is installed in a Supermicro H14DSH?

The modules run at DDR5-4800 (PC5-38400) with CL40 timing at 1.1 V, delivering the full 384 GB capacity across all six slots when the board's memory controller is fully populated.

How does the 288-pin RDIMM interface limit or enable performance in this server?

The registered 288-pin DDR5 RDIMM form factor buffers address and command signals, allowing all six 64 GB modules to operate at rated speed without signal degradation.

What physical clearance does the 6×64 GB kit need inside the chassis?

Each module is a standard-height 288-pin RDIMM without a heat spreader, so it fits the regular DIMM slots on the H14DSH motherboard without extra vertical clearance.
