New Ryzen 3800x build not booting on X570 with 4 sticks Ram

Could anybody help me I am about to pull my hair out.
Specs of system:
MSI MPG x570 Gaming Plus
Ryzen 7 3800x
Corsair CMK16GX4M2B3200C16 Vengeance LPX 16 GB (4 x 8 GB) DDR4 3200 MHz
Corsair RM850x
EVGA 1060 3gb
Samsung 960 NVME

So boot the system on 1 stick of 8gb, get windows installed, drivers etc.
shut the system down put 2 sticks in and let it run. I then set memory timings to match the spec on the box of the sticks, and it will no longer post. had to remove battery to reset and try again, try just setting the ram at 3200 and it will not boot. reset battery again.
Put all 4 sticks in at default and again it will not even boot on default settings.

It seems there is an error light on the mobo for RAM when not posting

This is my first build in about 15 years and especially new to AMD so not sure if its something obvious im missing, and I have always let the bios set things for ram in the past.

Could it be just a bios update is needed? I think I will be doing that after work today anyway as I read the changelog and some of the features added seemed useful for my board.
Is the ram just crap for this build?

Any insight would be greatly aprpeciated.

Edit: Just read DDR clocks drop off considerably when using 4 sticks to around 2400mhz? would that get the system to boot if I set that?

Yes, get your self on the latest BIOS. However you should be able to get all ram modules installed and the PC running if you don't set DOCP. That will allow you to as mentioned get the PC running and flash the BIOS.

Then reboot and set DOCP. The normal thing with Ryzen is for it to train the memory a few times so expect the PC to reboot a few times until it will either fail or boot successfully.

If it fails... even with latest BIOS then either someone with more knowledge than me can chip in or what I would do is just lower the frequency a notch until it boots.

I reckon eventually it will boot it's just a BIOS issue.

Saying that it has taken over two years for a BIOS for my Prime x370 to finally get DOCP working for my ram.

Considering you have a top x570 board my bet is it is a BIOS issue.

However I also notice you don't have Ryzen friendly ram. (Corsair CMK16GX4M2B3200C16 Vengeance LPX 16 GB (4 x 8 GB) DDR4 3200 MHz)

If this is new ram, send it back and by the DarkPro B-Die stuff.

Better yet check the QVL list for you mobo and buy based on that.

Thanks I will definitely try this when I get back,
Could you give some insight about the ram not being ok for the ryzen? In the compatibility page it has the X570 listed, this was recommended by a few people and I am a bit clueless when it comes to Ram and the types.

Check on the MSI website if your ram is in the list of compatible modules. It's generally called QVL list.

Seems to be on the compatible list.

So after a bios update the sticks seem to be working. although testing at a slower speed. When i try and go for 3200mhz, should i manually input the voltage of 1.35v rather than letting it automatically do it?
