Third RAM slot not working properly

(sorry for my english in advance)
Greetings all! Recently I bought myself a RAM (2 for 8) as a set to the already available exactly the same, in the same amount - Ripjaws v 3200, cl 16-18-18-38. 1.35 . In the end 32gb. Chocked all 4 slots, went into the bios and set xmp profile 3200 16-18-18-38, 25600. As a result, my computer would not start. I had to lower it to 2933, computer started and it seems even with the load in the games and software, no errors. Thought that maybe a defect in the RAM. Plugging the ram in and out, I found the motherboard's problematic SLOT. All ram runs normally only in 1-2-4 order on XMP. Back to 2933 again, all 4 slots work, but stress tests like tm5 still turn the computer off. Tried with different timings and voltages - with 3 slot it still does not pick up even 3000 mhz. So my question is, what may be the reason for the inoperability of the 3rd slot at the declared frequencies? Is it possible that this is the usual contact oxide and cleaning will solve the problem? Is it possible to say that the slot itself works, because it generally sees the memory and can start with it, but at lower frequencies? I don`t know all the nuances, so please don`t judge. Thank you!
Processor : ryzen 5600x 4.7, 1.3v
Motherboard : asus b450m gaming pro s
RAM : Ripjaws v 3200 on samsungs bdie, judging by typhoon
Bios : latest
Windows 10 ltsc

Most likely just a bad ram slot/motherboard, it happens. Have you tried putting a different stick in the third slot? Maybe just a bad stick?

I Have tried this morning, it didn't work on 3200 mhz. Bad slot? If it works on 2933, it can be considered as working one? Maybe it's a feature of ryzen or 450 socket?
