[SOLVED] XMP Unstable, Please Help

Specs:
RAM: 2x 8gb G.SKILL TridentZ RGB Series @ 3200 DDR4 ; 2x 8gb G.SKILL Aegis @3200 DDR4 Totaling 32gb (Yes, I know, overkill [and yes, I know, I mixed RAM]) Both have same Timings and Latency: Timing 16-18-18-38 CAS Latency 16
EDIT: For added clarity, I have TridentZ in DIMMB2 and DIMMA2 and Aegis in DIMMB1 and DIMMA1
MOBO: MSI x470 Gaming Pro Carbon
CPU: Ryzen 5 2600x at factory clock
PSU: Corsair CX750 750W
GPU: RTX 2070 Super
Storage: 2x M.2 Nvme 500gb
Cooling: AIO Coolermaster
Other: Pcie Wifi Card

When I try to boot my bios into the 3200 XMP Profile, it either won't post or isn't stable. I tried upping the RAM voltage to 1.4, which got it to post, but wasn't stable. Also tried upping the CPU SOC voltage to 1.00, which also showed no improvement. From what I've researched:

Ryzen 5 2600x

Max Type DDR4-2933
Supports ECC Yes
Max Mem 64 GiB
Controllers 2
Channels 2
Max Bandwidth 43.71 GiB/s
Bandwidth Single 21.86 GiB/sDouble 43.71 GiB/s
Memory Configurations
Single Rank
2 of 2 DDR4-2933*
2 of 4 DDR4-2933*
4 of 4 DDR4-2133
Double Rank
2 of 2 DDR4-2667
2 of 4 DDR4-2400
4 of 4 DDR4-1866
* - 2933 MT/s on motherboards with at least six PCB layers only, otherwise 2667 MT/s (four-layer boards).

I found one page online (a reviewer) that gave the number of PCB layers for the x470 as 4, but found no secondary confirmation. I also found a page that says that the TridentZ is single rank, but I can't any information about the Aegis. I read lots of forums saying that I should be able to push past the 2933 to get to my 3200. MSI lists both memory sets as being compatible with the x470. Am I being bottnecked somewhere? by the CPU or by the Mobo?

Any help greatly appreciated!

Try 16 gb one with trident one with aegis with xmp on if it works that means for the 32 gb that your BIOS will set all your RAM to the lowest compatible speed, mixing different sizes and speeds is also a terrible idea if you want your computer to be stable.

Both Sets of RAM have identical timings, latency, and size. I will try your suggestion though.

There are many, many timings on ram outside of the primary ones,and the primary ones are the only ones advertised. Odds are that your motherboard is having issues setting all of the secondary timings at the advertised ram speed you want. If I'm not mistaken, all your secondary timing need to match as well.

You could try to manually set compatible timings and speed yourself and attempt to hit the speed you desire
