32GB DDR4 ECC UDIMM kit for servers

This 32GB kit contains two 16GB DDR4 2400MHz ECC UDIMM modules built for servers and workstations that require error-correcting unbuffered memory. Each module uses a 2Rx8 dual-rank organisation and runs at the standard 1.2V DDR4 voltage. The 288-pin DIMM form factor fits compatible DDR4 server platforms only and is not suitable for desktop or laptop systems.

Sustained workload behaviour with ECC

Error-correcting code detects and corrects single-bit errors during continuous operation, helping data integrity stay intact under heavy, long-running workloads. The CL17 latency and 2400MHz speed deliver steady throughput for virtualisation, database and compute tasks that keep memory saturated for hours. Dual-rank density allows the memory controller to interleave accesses across ranks, maintaining bandwidth when all slots are populated.

Upgrade from smaller or non-ECC kits

This kit replaces lower-capacity DDR4 ECC UDIMM sets or non-ECC memory in systems that mandate ECC unbuffered modules. The jump is worth it when your workload exceeds the current memory ceiling or when the platform requires ECC for qualification and you are currently running unprotected memory. Verify the motherboard's qualified-vendor list and maximum supported capacity before installing.

Questions about this item

Does the 1.2 V kit add noticeable heat or power draw when the server runs 24/7?

Each 16 GB module operates at the standard DDR4 1.2 V, so the 32 GB kit adds minimal extra heat or power under continuous load.

What must my system already support to use this 288-pin ECC UDIMM kit?

The motherboard must accept DDR4 ECC unbuffered DIMMs at 2400 MHz with dual-rank x8 organisation and provide 288-pin slots.

Can I mix these 2400 MHz dual-rank modules with slower single-rank ECC sticks?

Mixing ranks and speeds is not guaranteed; the system will typically downclock all modules to the lowest common speed and may disable ECC or multi-channel operation.
