32GB DDR4 3200 ECC RDIMM

This 32GB DDR4 3200 registered DIMM delivers ECC error correction for data integrity in server and workstation environments. The 2Rx4 organisation and CL22 latency suit the ASRock Rack EPYCD8-2T platform. It operates at 1.2V without a heat spreader.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC detects and corrects single-bit errors that can accumulate under long-running workloads. The 1.2V rating keeps power draw stable across extended duty cycles.

DDR4 interface limits

The DDR4 3200 PC4-25600 interface caps peak bandwidth at the JEDEC standard rate for this speed grade. CL22 timing sets the minimum access latency the bus can achieve. The 288-pin RDIMM form factor fits only DDR4 registered DIMM slots.

Questions about this item

How much heat does the 1.2 V RDIMM generate under continuous load?

The module runs at 1.2 V with no heat spreader, so it relies on chassis airflow rather than active cooling to stay within JEDEC thermal limits.

Does my ASRock Rack EPYCD8-2T board need a specific BIOS revision to recognise the 2Rx4 registered DIMM?

The DIMM is validated for the EPYCD8-2T series; check the motherboard vendor's memory QVL for the exact BIOS version that enables full 3200 MT/s operation.

Can I mix this 32 GB ECC registered stick with unbuffered DDR4 already in the system?

Registered and unbuffered DDR4 cannot be used together — the memory controller will not initialise a mixed population.
