Product identity

This is a 16GB DDR4 3200 ECC UDIMM module built for ASRock Rack EPYC3451D4U-2L2T2O8R motherboards. It runs at PC4-25600 with CL22 latency, 1.20V voltage and a 2Rx8 rank configuration using major OEM chips.

Target fit

Suits administrators upgrading that specific ASRock Rack platform who need ECC error correction and unbuffered operation. Not for systems requiring registered DIMMs, non-ECC memory, DDR5 speeds or a different pin count.

Installation notes

Standard 288-pin UDIMM insertion takes minutes; align the notch, press until the latches click and verify seating. Common issues include mixing ranks or speeds across channels, forgetting to enable ECC in BIOS and exceeding the board’s maximum module count.

Questions about this item

Does this 288-pin DDR4 ECC UDIMM require a motherboard that supports ECC memory to function?

Yes, the module is an ECC unbuffered UDIMM and will only provide error correction on a motherboard with ECC support in the BIOS and chipset.

Can I add this 3200 MHz CL22 stick to an existing bank of slower DDR4 ECC modules without changing BIOS settings?

The module will down-clock to match the slowest installed kit, but all sticks must share the same 1.2 V voltage and unbuffered ECC type for stable operation.

How do I confirm the 16 GB stick is running at 3200 MT/s with ECC active after installation?

Check the memory speed and ECC status in the UEFI/BIOS main screen or use a tool such as dmidecode or CPU-Z to verify 3200 MT/s and ECC enabled.
