Compatible DDR4 ECC RDIMM kit

This 128GB kit contains four 32GB registered DDR4 modules rated at 3200 MT/s with CL22 latency. It is built for ASRock Rack ROMED8-2T motherboards running AMD EPYC processors and operates at 1.2V without heat spreaders.

Suited for registered ECC server upgrades

The modules target administrators expanding memory on the specified ASRock Rack platform where registered ECC RDIMMs are required. Builds needing unbuffered DIMMs, non-ECC memory, or a different pin count should look elsewhere.

2Rx4 organisation governs density and compatibility

Each 32GB stick uses a 2Rx4 configuration that determines how the memory controller addresses the chips. Verify that the motherboard firmware supports this rank structure before purchase.

Questions about this item

Will the 1.2V DDR4 3200 CL22 2Rx4 ECC RDIMM modules work reliably alongside existing registered DIMMs in my ASRock Rack ROMED8-2T?

Yes — all four 32GB modules run at 1.2V with CL22 timing and 2Rx4 organisation, matching the registered ECC RDIMM standard required by the ROMED8-2T, so they can be mixed with identical-spec RDIMMs already installed.

How can I verify the kit is operating at 3200 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 3200 MT/s (PC4-25600) and that ECC is reported as enabled; the registered RDIMM design ensures error correction functions once the platform initialises it.

What exactly ships in the box, and are any extra parts needed for installation?

The package contains four 32GB 288-pin DDR4 ECC RDIMM modules totalling 128GB; no heat spreaders, cables, tools or additional components are included or required for installation.
