Question Asus Tuf gaming B550 plus DDR4 3200 ram issues

[Xtream Rage]

Please help this is my first post .so I'm having ram issues on my b550plus. I read some where the the Corsair Vengeance pro RGB 3200. I started with 4 8 gig sticks which worked fine for a couple months then 2 of the slots stopped recognizing it . It would show the RGB lights and I did try different slots. Which all seemed to work but now only it the first 2 closest slots to the cpu. Which is a1& b1 . I believe that's incorrect but that is the only why I could get it by to work . . So yesterday it crashed so I went and bought 4 16 gigs sticks of vengeance lpx DDR4 3600 . . I can't get my system to boot. I've tried each of one stick which everything turns on except the monitors .I get a yellow light and then red with one stick . I've tried resetting cmos with screwdriver also I've pulled the onboard battery. I don't know what else to do. I'm upset and am ready get a new board if I can't figure this out . Pleaseee help

Welcome to the forums, newcomer!

Can you get into BIOS? If so, what BIOS version are you currently on for your motherboard?
Can you define what you mean by crash ?

I can get everything to boot except the display kb and mouse . I've manage to get the graphics fans to tur on along with all the others and cpu and the rbg lights from the 2 ram sticks I had in it the cosiar 3200 . Which initially I had 4 sticks for a couple months with no problems then I can no longer get the right 2 slots furthest away from cpu no longer will register. The RGB lights will but that's it. It won't boot and if I have more then 2 sticks In the video card fan don't run . No I can't seem to get into bios I wish. My last crash consisted of apex wasn't on long. I don't recall a bsod but it did crash and wouldn't post boot to bios even now. .. not sure what bios version i have . I might be able to check ?
I have the
Asus Tuf Gaming b550 plus
Cpu : Ryzen 5 3500 x
Heatsink :Cool master liquid cooled heat sink
PSU :Corsair cx650f RGB
Graphics: MSI Radeon 570 rx Armor
Ram : Corsair Vengeance RGB pro 8 gig x 4.

This ram should be compatible which worked just fine for a few months not sure what changed at that point I lost my 2 right ram modules but was still able to use the 2 on the left which I kno isn't suggested . I don't know much about ram and I don't know where I went wrong . I read sum where the 3200 isn't good for the board which isn't what the manual provides . So I'm have the point of just getting a new board cuz I think I fried my modules some how , even tho I can get the RGB to light up in them ... Thanks for your time patience and help

So I figured out what I did wrong , I wasn't aware that amd and Intel prefer defferent speeds. I used 4 sticks of ddr 4 3200 on my amd cpu which requires 3600. Which doesn't recognize even the 3600 now . I'm assuming I messed up my memory modules or cpu . . I about to get a new board . I just hope I didn't damage the cpu
