Capacity and form factor

This is a single 64GB DDR4 RDIMM rated at 3200MT/s with CL22 latency and 1.2V operation. It uses 2Rx4 organisation and ECC registered technology on a 288-pin module built with major OEM chips.

Suited workloads and limits

The module targets ASRock Rack ROMED8-2T platforms running AMD EPYC processors where registered ECC memory is required. It will not suit desktop boards that only accept unbuffered non-ECC DIMMs or systems that cannot address a 64GB single rank configuration.

Headroom and capacity ceiling

One module delivers 64GB of registered capacity with error correction for multi-socket server workloads. Total system memory scales with the number of populated slots on the qualified motherboard; the practical ceiling is defined by that platform’s slot count and memory controller limits.

Questions about this item

What motherboard slot and DDR generation does the 288-pin RDIMM require?

The module fits a 288-pin DDR4 RDIMM slot; the motherboard must support DDR4 registered ECC memory.

Will the CL22 3200 MHz module downclock if installed beside slower DDR4 RDIMMs?

Yes, the module will run at the lowest common speed and highest latency present on the channel.

How can I confirm the 64 GB stick is recognised at 3200 MT/s with ECC active?

Check the BIOS memory summary or OS tools such as dmidecode for 3200 MT/s, ECC enabled, and 64 GB capacity.
