UPDATE: SOLVED
Update 10/1
Not sure if anyone still cares on this thread, but it turns out the problem was in fact the processor, as much as I didn't want that to be the case, lol. I finally caved and bought a replacement processor with the same specs as the original, and it worked with no issue whatsoever.
Don't really know what the deal was with the old one, it seemed to work perfectly fine up until the point where I tried booting with multiple sticks of RAM, but I guess that's just how hardware issues go sometimes.

Got a bit of a weird issue I guess, my build list is here: https://pcpartpicker.com/list/ZWxY3b
or in plaintext:
CPU: Intel - Core i7-9700K 3.6 GHz 8-Core Processor
CPU Cooler: Cooler Master - Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: Asus - PRIME Z390-A ATX LGA1151 Motherboard
Memory: G.Skill - Aegis 16 GB (2 x 8 GB) DDR4-3000 Memory
Memory: Corsair - Vengeance LPX 16 GB (2 x 8 GB) DDR4-2933 Memory
Storage: SanDisk - SSD PLUS 240 GB 2.5" Solid State Drive
Storage: Western Digital - Caviar Blue 1 TB 3.5" 7200RPM Internal Hard Drive
Video Card: MSI - GeForce RTX 2060 6 GB VENTUS OC Video Card
Power Supply: EVGA - SuperNOVA NEX 650 W 80+ Gold Certified Fully Modular ATX Power Supply
My issue is that no matter what I do, I can't seem to get this motherboard to recognize 2+ sticks of RAM. I've tried every configuration of RAM in the four provided slots, but it refuses to recognize more than 1. The only exception has been, when you look at the layout like Processor | A1 | B1 | A2 | B2 | , I've put an 8 GB stick into A1 and B1 and the computer has booted. In this case, Windows 10 tells me that it recognizes 16 GB, but when actually attempting to use it, the actual usage caps out at 8GB.
The crazy thing is that I've tried every bit of hardware troubleshooting I can think of - I RMA'd this Mobo for an identical one, and am running into the exact same issue with the new one. I have two sets of 8GB ram sticks as you can see in the list above, I had the DDR4-3000 originally and tried those out to no avail, and just recently purchased the DDR4-2933 as reading the motherboard's manual advised that 2933 was definitely supported by the motherboard. I had hoped that would be the issue, but I got the exact same results this time as well.
To be clear on what happens when I attempt to boot with two sticks of ram, the motherboard has these little indicator lights that show what part of the computer it's attempting to POST. It goes CPU - Memory - VGA - then finally OK and boots. When I have one stick in, it does this sequence perfectly and boots up no problem. When I have two sticks installed, it lights up CPU, then Memory, then immediately the power cuts out and it tries to POST again, CPU, Memory, restart. After about 5 attempts of it restarting itself, it will just hang with the Memory light on indicating that the RAM is the problem. No other components seem to have any issue.
I just don't get it, it's two different (though identical model) motherboards, and two different sets of 8GB RAM. Anyone experienced anything like this?
