[SOLVED] Using 4x8gb 2400mhz ram lowers my mhz

So I have 4x8gb 2400mhz ram sticks. My motherboard is an ab350m - gaming 3, which is dual channel, but I was aiming for that 32gb of ram. My goal is 3d modelling and game design and I know 8gb would be enough for gaming but I was aiming for more. CPU - ryzen 5 2600

2x8gb is fine, but if I put all 4 of them, it drops to 1800mhz. I also notice my pc is booting way slower than previously. What's going on? Is there any way around this?

Make sure your RAM module is compatible with the boards configuration limitations. For RAM it is the following:
  1. 4 x DDR4 DIMM sockets supporting up to 64 GB of system memory
  2. Dual channel memory architecture
  3. Support for DDR4 3200(O.C.)/2933(O.C.)/2667*/2400/2133 MHz memory modules
    * Support for higher than DDR4 2667 MHz may vary by CPU.
  4. Support for ECC Un-buffered DIMM 1Rx8/2Rx8 memory modules (operate in non-ECC mode)
  5. Support for non-ECC Un-buffered DIMM 1Rx8/2Rx8/1Rx16 memory modules
  6. Support for Extreme Memory Profile (XMP) memory modules
Also make sure your CPU is compatible with 32GB of RAM at 2400MHz.

the cpu i am using is ryzen 5 2600
 
this is my screen - View: https://imgur.com/a/lRKBj8Y
this is where the xmp is supposedto be but it isnt
That is a sub menu of the M.I.T menu. The XMP setting should be on the first menu of M.I.T and if you have an XMP setting for 2933 or 3000MT/s use that because 3200 will not work without timing and voltage tweaking which will take time to get right. 2933/3000 is usually the highest you can get with 4x8GB on Ryzen 2000. Edit Misread the speed of the ram. Was thinking something else.

Try setting voltage to 1.25v with 2400Mhz and leave the timings at auto and see if it works.
