Exact-match server upgrade

This 512GB kit contains four 128GB DDR5 registered ECC RDIMMs built for the Supermicro X14SRA-T motherboard. Each module runs at 5600 MT/s with CL46 latency at 1.1V using a 4Rx4 organisation. The 288-pin form factor matches the board's memory slots precisely.

Registered ECC architecture

Registered buffering reduces electrical load on the memory controller so all four slots operate at full capacity. On-die ECC detects and corrects single-bit errors automatically, preventing silent data corruption in production workloads. No heat spreaders are included, relying on server chassis airflow.

4Rx4 rank configuration

The quad-rank-per-module design determines whether the motherboard can address the full 512GB at rated speed. Verify the X14SRA-T manual for approved population order and maximum supported capacity before installation. Builders needing different rank counts or unbuffered DIMMs should select another kit.

Questions about this item

Will the 128GB 4Rx4 modules need any firmware updates or reseating to stay stable over time?

No firmware updates are required for the DDR5 ECC RDIMM modules; the registered design and on-die ECC maintain signal integrity, so the kit remains stable without periodic reseating.

What limits sustained throughput first — the 5600 MT/s data rate or the CL46 latency — when all four slots are populated?

With four ranks per module at DDR5 5600 CL46, the CAS latency of 46 cycles becomes the first bottleneck during continuous read-write streams.

How much noise and heat do the bare 288-pin RDIMMs produce when the server runs all day?

The modules have no heat spreaders and draw 1.1V; they add minimal heat and zero acoustic noise, relying on the chassis airflow for cooling.
