Is it a UDIMM 1Rx8/2Rx8/1Rx16 memory module?

In the above manual, under "1-2 Product Specifications", it says "Support for non-ECC UDIMM 1Rx8/2Rx8/1Rx16 memory modules".

On the above product page, the "Description" and "Specifications" say nothing about "1Rx8/2Rx8/1Rx16". Should I assume it is 1Rx8/2Rx8/1Rx16? How can a user make sure that a UDIMM is compatible with the motherboard before purchase?

I contacted ADATA Customer Service Center and got the following reply:
"Compatibility issues that need you to confirm with motherboard manufacturers."

I don't think that memory is certified compatible.

Do you mean I should buy only the ones listed in the PDF mentioned in your post?

Whenever possible, yes.  The ones which appear in a different color have been tested and are certified compatible by Gigabyte.  Some of their boards are very finnicky.  Nothing's worse than getting your build together only to find that it won't POST, boot or run reliably because of a memory choice.  Using QVL RAM just increases your probability of success.
