RAM Overclock Causing Crash???

Hello all! I've used the forums here a ton and have gotten a lot of answer but I am in a situation that I cannot find an answer for so I am making my first post in search of help!

I recently got back into PC gaming and upgraded my PC. I am not a 'noob' at computers and this is not my first build - however I am stuck with overclocking and I'm not sure what the problem I am running into is exactly.

Before I carry on, I will list my components so the rest of the thread makes sense...

MBO: ASUS ROG Strix B350-F Gaming (BIOS version: 3803)
CPU: AMD Ryzen 3 1300X (Currently clocked at 3.85 GHz @ 1.337 V & Liquid Cooled)
RAM: 2 x 8 Gb Corsair Vengeance DDR4-3000MHz - AND - 2 x 8 Gb T-Force Night Hawk DDR4-
3200MHz
VGA: Gigabyte GeForce GTX 1060 GDDR5 3Gb
750W Corsair Power Supply

So the first thing I did was overclock the CPU and the CPU only.. I was able to push it to 4.0GHz @ 1.4V and achieve stability during benchmark testing while only reaching a max temperature of 46.3C. I tried to push it further than 4.0 and for some reason could not... pushing to 4.1 even with increased Voltage would cause a complete freeze once benchmark testing began. So I gave up on trying to figure out why I can't push past 4.0 and started to mess with RAM

Here is where the problems begin...

So according to BIOS my RAM at stock was at 2133 MHz @ 1.205V with 15-15-15-15-36 timings

I tried to manually push everything up and no matter what I tried with the frequency, voltage, and timings, every time I would save and restart my PC would crash - losing power - then would get stuck in a boot loop and I would have to cut power to get it to reset and restart again.

The BIOS has two TPU profiles (1 and 2 for fan cooled and liquid cooled), and when I activate the TPUII profile, it clocks my CPU at 3.85GHz @
1.337V and pushes the RAM to 3200MHz (while enabling D.O.C.P. - which when I manually activated without enabling TPUII would cause the same boot loop crash) @ 1.45V with 16-18-18-18-38 timings and everything is fine! Save and reboot at this point does not cause a power crash followed by a boot loop and boots up to windows fine... runs benchmark testings fine with no freezes... and temperatures are still at acceptable ranges.

It seems as if when I try to manually overclock the RAM and CPU my computer does not like it... even with TPUII settings, if I try to push the CPU from 3.85 to 3.9 it again causes the power crash and boot loop to occur.

Please help... I don't know what is going on. I don't have any manual control over my overclocking...

Multiple kits of memory have no guarantee to be compatible together, regardless of brand or model number. I suggest you remove one kit, clear CMOS. and try setting memory parameters in BIOS. You might start at 2666MHz and see if that works before going higher.

Understandable. But how come I can have a stable OC off of the TPUII profile?
