Question, I have a Ryzen 5 5600x CPU & an ASUS mobo with the latest BIOS. AMD claims that the 5000x series CPU's support up to 3200MHz RAM. I just purchased 2x8GB sticks at 3600MHz. The mobo accepts up to 4400MHz so I know that I'm good on that aspect. If I enable D.O.C.P. and set the frequency of the RAM to 3600MHz, will my system run 100% stable? I've read online that the "sweet" spot for Ryzen 5000 series CPU's is (depending on where you look) between 3600 or 4000MHz. So, from that info, I would assume that my system will be fine. However, I want to of course make SURE that if I set my RAM to the proper XMP/DOCP profile of 3600 - that it doesn't mess anything up in my brand newly built gaming PC that I put a good amount of money in :D. I realize that I can gradually increase the RAM speed in the BIOS and then experiment, but from your experiences - or other PC tech people that you have tapped the knowledge of - do any of you believe that a system like mine will be "solid" with the 3600MHz setting? Thanks!!

I have the MSI B450 flavour and 2x 8gb 3600 and set the XMP to 3600 in the BIOS. Has worked flawlessly for almost a year now.
So i would say no problem for you.

Yeah it should be perfectly stable with DOCP mode (i.e. XMP) unless there's something wrong with the memory. Just remember to set FCLK to 1800 to match it.

You can manually set RAM speeds beyond 3600MHz but stability isn't guaranteed. You should get 3800MHz and a 1900 FCLK with no problems though.

Just built my 5800x system recently. I have faster ram but I'm running at 1800 interface speed which is 1/2 of 3600 which is where I'm running my ram.
1900 interface is fastest my chip will run = 3800 at 2x buss. Since you have 3600 ram and if you turn on docp that will set all the timings, then set 1800 interface (forget what its called sorry)
If you run into issues, loosen your timings. There's tons info on utube as is where I started just last Nov.. Have fun

Thanks for all the advice so far! Regarding the above quote, I looked at a couple of Youtube vids that didn't mention anything about changing the FCLK. Both videos were from what I can tell very experienced OC'ers and they just said to Install the RAM, go into BIOS, change the "Auto" setting to "DOCP", select your RAM's specific frequency, then Save your changes. I have a ASUS Prime B550 mobo with the latest BIOS. Thoughts?

Ignore the 3800mhz suggestion and confirm you can run docp at 3600mhz first. At 3600mhz and under docp will "automatically" set your fabric clock aka fclk to the right ratio to be half your memory speed. If you choose to test the waters and run a higher dram speed, you'll have to manually set fabric clock to whatever speed it needs to be to maintain the 2:1 ratio manually. But as I wrote, best to avoid that till you've managed to get 3600mhz running first. And the kicker with raising ram speed is that you get yourself into situation where you will have to set a whole bunch of settings to make it work, etc and if you're not prepared it can be a huge pita. This often doesn't get mentioned...

Awesome, thanks for the clarification. I'm only planning on going to 3600MHz and that's it. I don't want to get into the weeds and mess around with anything that requires a bunch of changes/tuning and risk anything going wrong. Cheers!

Benchmark Scores Lots of RGB, so you know it's fast.
5800x is officially rated to 3200, but 99% of people with fast enough ram can hit the IF (infinity clock) ceiling with the ram at 1900Mhz on the IF, 3800 on the RAM.

3600 should be relatively simple with just enabling DOCP/XMP, maybe raising the SoC voltage to 1.1 if you have issues
