I did some testing as follows:

I removed and reseated the CPU.

I reset CMOS.

I started the computer and had the same result as described in original post.

I removed all memory sticks. Referring to the manual:

I put one memory stick in slot DDR4_2_1A. The computer started up and the bios utility showed 16384 MB in DIMM 1, and 16384 MB Total Memory, as expected.

I then removed the memory stick.

I put the same memory stick in slot DDR4_1_1B. The computer started up and the bios utility showed 16384 MB in DIMM 3, and 16384 MB Total Memory, as expected.

I then removed the memory stick.

I put the same memory stick in slot DDR4_2_1C. The computer would not start. The DRAM light on the mobo remained lit for about 30 seconds, then the computer rebooted, and the sequence kept repeating.

I then removed the memory stick.

I put the same memory stick in slot DDR4_1_1D. The computer started up and the bios utility showed 16384 MB in DIMM 7, and 16384 MB Total Memory, as expected.

(I properly turned off machine and removed power cord before resetting CMOS, reseating CPU, and between each memory relocation.)

From these tests I conclude that slot DDR4_2_1C is defective. I will return the mobo to Amazon as a defective unit.

I am having the same exact issue, with the same slot. Is there a massive manufacturing issue with these boards? Granted 95% of the users wouldn't see this, as they would not install more than 32GB of RAM.

Did you try a new MOBO what happened?

My CPU ID is reading out 128gb RAM and Windows only shows 96GB
-- I bought a full set via newegg:

CORSAIR Vengeance LPX 128GB (8 x 16GB) 288-Pin DDR4 SDRAM DDR4 2666 (PC4 21300) AMD X399 Compatible Desktop Memory Model CMK128GX4M8A2666C16

Using i9 7920x CPU

Any help is appreciated

helloworld: The majority of users problems are not manufacturing problems. Users want to 1-800-Gigabyte as soon as something goes wrong. The prices of these products can't sustain qualified people to work the phones. It's sad but it's true =(

Gigabyte very well may have the worst support of any tech company I've ever dealt with

sreilly24590....you probably have to go in to bios and tell it to boot to alternate source or change boot menu. There is a Function key you can hit during power up which brings up a Boot Menu where you can select which source to boot from as well.

Issue is it won't boot from the Windows 10 DVD or USB. It asks to boot from drive and after hitting any key just sits there doing nothing. The cursor goes to the upper left and just blinks. No activity. BIOS shows all installed components. Suggestions? RAM
