I doubt the SSDs were the cause of the failure to POST. My guess is the memory was the cause.

Have you tested both DIMMs individually, to make sure both work? Also check both DIMM slots, to be sure both work, in case you have a bad board.

Another cause of the memory failure could be bent pins in the CPU socket.

Are you sure your memory is the G.SKILL F4-2400C15D-16GVR? Your listing in the first post show "Z170/X99", while G.SKILL only shows Z170 boards as compatible. Or was that line pulled from PC Parts Picker?

I would connect the SSDs again with the one DIMM installed, and see if you can POST into the UEFI.

Were you really going to have two drives connected when you installed Windows? Not a good idea unless both SSDs will always be in that PC.

While I agree a newer UEFI version is a good idea, I'm not sure the latest 7.10 version is a good idea. Any of the ASRock Z170 board's 7.xx UEFI versions add compatibility for the upcoming Intel Kaby Lake processors. Some users have reported less than ideal results with those versions. My Z170 board seems unaffected, and I don't know either way about your board. But why chance it at this point since the 7.10 UEFI does nothing for you that the 2.30 version already does.

Your memory should default to 2133 in the UEFI, do you see it at that speed?

What is printed on the sticker? Assuming you yourself haven''t updated the BIOS, the board is new, not used, second hand nor open box, the printing on the sticker is the BIOS it came flashed with from the factory. I'll check when I get home, thanks.  Make sure it's stable first by testing the way it booted, then upflash to the latest NON-BETA BIOS. Use Instant Flash from within the BIOS. It's the safest means to flash with.
