I'm new to building PCs and planning my custom setup. I'm looking for a good motherboard to pair with my DDR5 RAM, specifically Corsair Vengeance 2x16GB kits (32GB total, aim to use four sticks). I noticed that some motherboards list speeds as high as 6400MHz while my RAM runs at 6000MHz. Is it safe to use my 6000MHz RAM on a motherboard that supports 6400MHz? I want to make sure there won't be any issues. I've also seen some troubling reviews about DDR5 stability, especially with four sticks, so I'm also considering a DDR4 build as a backup. Any advice would be appreciated!

In general, working with multiple kits isn't recommended due to potential compatibility issues. If you're eyeing 6000MHz, a two-stick kit is definitely more reliable than mixing kits. It sounds like you're leaning toward brands like ASUS or Gigabyte, which is solid; they have good reviews. Just make sure to check that the combination works before you buy!
Avoid using four DIMMs with DDR5; it often has stability issues, especially over 5200MHz in a 'double-populated' setup. If you need more than 32GB of RAM, aim for a two-stick kit with higher capacity, like 96GB total with 2x48GB. This will make your build much smoother.
Generally, motherboards mention the highest RAM speed they can support. If a motherboard supports 6400MHz, it should also work with 6000MHz without issues. However, be cautious with DDR5; I've heard it can be unstable with more than two RAM sticks. If you're looking for 64GB total, consider using a single kit of 2x32GB instead of two 2x16GB kits. Also, using pcpartpicker is a smart idea for checking compatibility—it can save you from many headaches.
Thanks for the tip about pcpartpicker! Good to know that it's not just the max speed that matters; that clears things up for me.
Just to confirm, when they say 'maximum memory' in the specs, they mean RAM, right?
I get that! I was worried about costs too, especially for higher capacity sticks. Sticking with a single kit sounds easier and might save some cash.
