Compatible Server Boards

This 32 GB kit is built for ASRock EPC612D8, EPC612D8A, EPC612D8A-TB and EPC621D8A server boards. It delivers two 16 GB DDR4 2400 registered ECC modules that the vendor validates for those platforms only.

Upgrade Path

The kit adds 32 GB of registered ECC memory to a supported board, replacing non-ECC or unbuffered DIMMs that the platform cannot use. The jump is worthwhile when the workload demands error correction and the board accepts RDIMMs up to 256 GB total capacity.

Pre-Installation Checks

Verify the board model matches one of the four listed part numbers and that all populated slots will use registered ECC DIMMs. Mixing RDIMM and LRDIMM modules is not supported, and the memory will clock down to the speed allowed by the installed processor.

Questions about this item

Will these 288-pin DDR4 DIMMs fit the eight memory sockets on my ASRock EPC612D8A board?

Yes, the kit provides two 288-pin DDR4 registered DIMMs designed for the eight sockets on the EPC612D8, EPC612D8A, EPC612D8A-TB and EPC621D8A server boards.

What is the correct way to install this 2Rx8 registered kit so the system recognises all 32 GB?

Populate identical 2Rx8 modules in the same channel pair and follow the board's slot order; mixing registered and load-reduced DIMMs is not supported and will prevent boot.

If I later expand to the board's 256 GB registered-DIMM limit, do these 16 GB sticks stay compatible?

Yes, each 16 GB module runs at 1.2 V and DDR4-2400, so additional matched registered DIMMs of the same speed and voltage can be added up to the 256 GB maximum.
