I can't get my PC to work when I set my RAM above 2133mhz, even though it did work at 3200 before i swapped the GPU and updated the bios. Can't even work on 2400, anyone has any ideas?

Things I tried:
-XMP profiles
-MSI Memory-Try-It
-Increasing timings
-Bumping SOC/NB voltage to 1.2
-Bumping RAM voltage to 1.4
-Reverting BIOS to v4 and v5
-Manual OC (2400mhz, 1.4v RAM, 1.20v NB, very loose timings, T2 step)

Specs:
- MSI B350M PRO-VDH (current beta bios(v6), tried reverting, still didn't work on old BIOS)
- Ryzen R5 1600 STOCK (I think 3.8 boost is enough)
- Corsair 3200mhz Blue LED RAM (CMU16GX4M2C3200C16B)
- Gigabyte GTX1080 Windforce 3x OC
- 120gb ssd and 1tb hdd

I cannot help you, but perhaps it would be helpful to know more details about what happens when you set it aboce 2133 MHz, e.g. which parts of the boot process will still run normally and if you get an error message, if any.

Did you try to lookup the issue in the manual for you motherboard? In some cases it's necessary to push a "MEM OK" button on the board or something similar. I'm just guessing, but since nobody else helped you it should be worth a try.

If everything was working, my suggestion is to NOT update the BIOS. You only want to do this if something is wrong.

Personally, i have had issues with MSI's BIOS update. I found V15 to be perfect for me, with the mobo getting more unstable with BIOS update. Flash back to when you had a working BIOS and see if it accepts the memory clock then.

If it doesn't work, then run memtest86 on it. I had this issue this weekend, with the original Bios no longer working, and memtest came up with a crapload of errors. Leads me to believe it is an issue and should be RMAd.
