Looking at supported memory speeds for a mobo, am I not guaranteed to be able to run at a frequency not listed? - example:

Recommended Posts

Example: MSI B450 Tomahawk lists up to 3466Mhz, but excludes numbers like 3400, 3333, and more. I'm not talking about overclocking, I just want to know if will *certainly* be able to run say a 3400Mhz kit at 3400Mhz even though it's not on the list. My thinking is that they list the ones they test extensively, but I am not sure to what extent there is confidence in ones not listed even if they are below the "maximum" or highest listed. Also, is there anything else to worry about? Like, might I be restricted in how much I can adjust the timings because it's not "supported"? - stuff along those lines.

 

Thanks a bunch in advance.

1866/ 2133/ 2400/ 2667Mhz (by JEDEC)
2667/ 2800/ 2933/ 3000/ 3066/ 3200/ 3466 MHz (by A-XMP OC MODE)

So yes, 3200MHz is fine.

 

Any speed up to the maximum rated should work. Higher speeds may work, but are not likely officially supported.

Sorry I misread the specs; edited. I was not looking for specifically 3200Mhz or any in particular yet, I just want to know about ones that aren't listed and aren't higher than 3466. Thanks.

Yes it can run the memory at any speed you want, as long as the memory can handle it.

No caveats?

Well as long as the memory can handle the speed, then it will work.

Why would mobo manufacturers bother to list "supported" speeds and not even include all of the normal ones if that is the case? I believe what you are telling me, but it doesn't really make sense.
