I am sure that this is posted quite often, but I can't seem to find anything that quite fits me.

CPU: Ryzen 5 2600X (Auto OC at 3800MHz)
GPU: Sapphire Radeon RX 5700 XT Nitro+ OC 8 GB
RAM: HyperX Predator 3000mhz 2x8GB + 2x4GB CL15 (Same type, just different size)
MB: ASUS TUF X470-Plus Gaming
PSU: Corsair TX750m

The ram is at 2400MHz, and I can't seem to change it. I've confirmed it with CPUid.
The ram I have is Intel optimized, but it should still work on ryzen...
Now, I've tried manually setting in the timings and voltage at 15-17-17-17-36 and 1.35V, and I've tried the auto d.o.c.p, which also doesn't work for me.
After trying those methods my pc starts and shuts down 4 times before I can enter bios again.


I might be missing some info here, I'm very tired.
 
Solution
Remove the 4gb's and have the two 8gb sticks in 2nd and 4th slot from cpu.

Ryzen 1st/2nd gen (not sure about 3rd) is known not to work well with odd timings and 3000 speed. Try cl16, 18, 18, 18, 36 at 2933 if 3000 doesn't work with even timings.

Having all dimms populated can be another issue as well.

I've already tried taking out the 2x4gb ones, didn't make any difference. 8gbs are already in 2nd and 4th slots.
I haven't tried different timings, so I can try that.
Thanks!

And don't forget to set dram voltage to 1.35v. Maybe SoC too, at 1.1v, work your way up to 1.2v depending what you get at 1.1v.
Hey
I tried what you told me, but it didn't work, unfortunately.
I think I'll just leave it be, 2400MHz is the end of the world for me. It might just be this damned motherboard.
Thanks for trying to help!
