I'm in the process of building my new PC with an MSI MAG B650 Tomahawk WiFi motherboard and Corsair Dominator DDR5 7200MHz RAM. However, I've heard that 7200MHz is technically considered overclocking for AM5 platforms. Will I be able to build my PC with this RAM, and if necessary, can I just run it at a lower frequency? Will it automatically throttle down, or is there a risk of damaging anything?

While 7200MT/s RAM should technically work, it's often better to stick with around 6000MT/s for gaming. There may be diminishing returns on performance with higher speeds like 7200MHz. If your kit has a 6000MT/s XMP profile, you might want to use that instead for more stability.
Yeah, for most games, the benefit of using higher speeds isn’t always noticeable, and you may find 6000MT/s can perform just as well or better depending on the situation.
The RAM will typically default to a lower speed like 4800MT/s until you adjust the settings manually. It’s quite unlikely you’ll reach 7200MT/s with AM5 without tinkering, so trying to stick around 6000MT/s should keep things stable and hassle-free.
Got it! I’ll keep that in mind.
So I shouldn't worry about frying anything?
As for potential risks, nothing should break. The PC might not perform at its peak efficiency with 7200MT/s, but if you underclock to around 6000-6400MT/s, you’ll be fine. Just be careful with timings and enjoy building your PC!
Just to clarify, if I set it to 6000 before booting, I should be good?
Exactly! Just enable that profile and you should be all set.
Yes, you can run the RAM at a lower frequency without any issues. Just setting the profile to 6000MHz should work fine for you. Most boards will automatically adjust to a base speed like 4800MHz until you enable the proper XMP/EXPO profiles. Just keep an eye on your timings and latencies as you might need to tweak those too.
So, I can just set it to 6000MHz and it’ll be stable?
You'll definitely be able to run 7200MHz RAM at lower speeds. If you run into stability issues at 7200MHz, just lower it to around 6000MT/s and you should be in good shape. Also, make sure to check if the RAM is on the QVL list for your motherboard to ensure compatibility.
What if I want to try the 7200MHz speeds anyway?
Thanks! That's reassuring.
Is there really a big difference between 6000MT/s and 7200MT/s for games?
