8GB DDR4 3200 ECC RDIMM for ASRock EPYC boards

This registered DDR4 module delivers 8 GB of ECC memory at 3200 MT/s with a CL22 latency. It is built for the ASRock Rack ROMED8-2T motherboard and AMD EPYC server platforms that require registered DIMMs.

Tool-free DIMM slot installation

The 288-pin RDIMM seats in standard DDR4 slots without tools, but the registered buffer means it will not work in consumer boards that accept only unbuffered memory. Verify the motherboard manual for population rules and maximum module count before fitting.

Single-rank 8 GB capacity with 1.2 V operation

The 1Rx8 organisation provides one rank per channel, leaving headroom for additional modules up to the board's supported limit. Systems needing more than 8 GB per channel or higher frequencies than 3200 MT/s will require different modules.

Questions about this item

How do I confirm the module is running at 3200 MT/s with CL22 timings after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report DDR4 3200 speed and CAS latency 22 for the installed DIMM.

What comes in the package and do I need any extra parts to install it in an ASRock Rack ROMED8-2T?

The box contains one 8 GB DDR4 3200 ECC RDIMM; no additional components are required for installation in the compatible motherboard.

Which capacity should I choose if I want a single registered ECC DIMM for this platform?

This part is an 8 GB 1Rx8 registered ECC module; select it when you need one 8 GB DIMM for the ASRock EPYC motherboard.
