What this kit is and who it fits

This 32 GB kit contains four 8 GB DDR4 2400 registered ECC DIMMs built for the ASRock EPC612D8, EPC612D8A, EPC612D8A-TB and EPC621D8A server boards. The modules run at 1.2 V with CL17 timing and use a 2Rx8 organisation. They are intended for administrators expanding memory on those specific platforms.

Check your board before ordering

Verify that your system is one of the four listed ASRock server boards; the memory is validated only for those models. The platform supports registered ECC or load-reduced DIMMs but does not allow mixing the two types. Installed modules will clock down to match the processor’s maximum supported speed, so confirm the CPU’s memory capability. The board provides eight DIMM sockets and accepts up to 256 GB with RDIMMs or 512 GB with LRDIMMs.

Who should buy and who should not

This kit suits IT teams adding 32 GB of registered ECC capacity to the named ASRock servers. Buyers who need non-ECC unbuffered memory for a workstation or desktop should look elsewhere. Builders requiring a different capacity, speed or form factor will not be served by this specific four-stick package.

Questions about this item

What is included in the package and is anything else required?

The package contains four 8 GB DDR4 2400 MHz ECC Registered DIMM modules. No extra parts are needed if your ASRock EPC612D8, EPC612D8A, EPC612D8A-TB or EPC621D8A board has free 288-pin slots.

Which kit capacity should I choose for my server?

This 32 GB kit (4 × 8 GB) is the only capacity offered under part C123. The supported boards accept up to 256 GB with ECC RDIMMs or 512 GB with LRDIMMs across eight sockets.

What does the 2400 MHz rating mean once installed?

The modules run at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V. Memory will clock down automatically to match the processor’s maximum supported speed.
