You can PM EVGATech_DaveB he is working on the Motherboard Manuals and can correct it.
 
Yes it is as far as being able to edit your own Post.

Thank you for bringing this information to our attention. From the information we have and can find the two boards should agree. The Primary slot should be 2 and 4 and a single stick should go in slot 2. We will reach out to Product Team to review our information and correct the manual.

I have confirmed that slot 1 and 3 are primary.  The physical manual that came with the motherboard indicated slot 2 and 4, and the digital manual still says 1 and 3 with the diagram indicating 2 and 4, but I got an error and the RAM did not power up in slots 2 and 4 and are working perfectly in slots 1 and 3.  Both manuals need to be updated.

Something is wrong with your board then. Slots 2 and 4 are populated on my Z170 Classified K. No issues. Please refer to this image from a review of the Z170 FTW, you can clearly see slots 2 and 4 are populated.

I really don't know what to say about that... Clearly in that picture it's a Z170 FTW with slots 2 and 4 in use, but on mine it wouldn't boot until I moved them to 1 and 3.  My picture is a bit grainy, but here it is.  

That is really odd...What happens if you have only one stick of RAM in slot 2?

I didn't get around to troubleshooting until now, because despite the motherboard beeping at me when I boot it, everything works fine and all the RAM is showing up in settings. I purchased 2 more sticks of RAM to upgrade, and figured that once all 4 slots were populated I'd stop getting beeps, but it hasn't worked. Now I've played around with it to see if any of the sticks have an error and I can't find one. With 1 stick in slot 2 I get error code 53 and the computer won't boot. In slot 1 it works fine, but I get 4 motherboard beeps. I'm trying to determine if it's somehow a RAM error or a timing error, but everything works perfectly. With all slots populated all RAM shows up and boots fine, but I get 4 beeps. Should I return the motherboard?
 
Here's a picture of slot 2.

My old EVGA motherboard beeped to let me know it was booting and going through the boot codes. You may be able to disable the speaker in the bios.


I think it was “dark” mode on the board that’s i had.

If the board is working fine, it may just be the bios speaker being loud, but I haven’t had an EVGA motherboard in a few years, so I am not sure if they removed or disabled the speakers.

Check this and other EVGA manuals in the BIOS section with LED code readouts the BIOS now uses beeps for non error audio indications.  ie the more USB devices detected the more beeps.
 
might be a security thing  IE your have a USB flash drive connected you did not know is there.
