Server ECC RDIMM upgrade

This 32GB DDR4 2400MHz registered DIMM carries ECC error correction and a CL17 latency at 1.2V. It targets Dell PowerEdge R930, T430 and R630XL servers that require registered memory for stable operation in multi-socket configurations.

Compatibility checklist

Verify that your system accepts 288-pin DDR4 ECC RDIMM modules and does not mix registered with unbuffered memory. Confirm the motherboard supports PC4-19200 speed and 2Rx4 rank organisation before installation.

Sustained workload behaviour

ECC circuitry detects and corrects single-bit errors continuously during long compute runs, preventing silent data corruption. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity when all slots are populated under heavy traffic.
