I had this strange problem a few months ago. My 4-year-old PC that never worked before started acting weird and stopped showing up on screens. It was running a 5600X processor and some RAM sticks I thought were fine, but the whole thing wouldn't start after lots of testing. I figured out later that the CPU had actually died, so I bought a new 5700X. But then it wouldn't even turn on when trying to add all four of those memory modules, even though every single one worked perfectly on its own and had been working together for years without any issues. So I ended up buying two more sticks to fix that booting problem. Now I need to upgrade the system again because some software needs more than 32GB of RAM, but I'm worried it's going to act the same way next time and I won't be able to start up the PC with all those sticks. The RAM sticks are Kingston KF432C16BB/16s. What do you guys think about this?

The faster the RAM speed (rated frequency), the more strict the timing needs to be. This means slots get used up quickly and the CPU's memory controller gets stressed out. Also, age of the parts and voltage levels matter, plus the luck with your specific chips. Usually, no two memory controllers can handle the same settings perfectly. It is best to stick with two DIMM kits together. If you don't have enough RAM from 2 DIMMs because they aren't compatible or available, then avoid high frequency modules altogether, or just skip EXPO entirely.

Thanks man, I am not creating original characters or content. The speed of these modules is only 3200Mhz. I think I will give them a shot because I can't afford anything else at this moment and I really need more RAM in the system.

2,667 on four sticks for AM4*. I tell people not to try overclocking RAM because you just set a number and hope it works - even an "XMP" setting can cause problems. This happened way back with Phenom II x6 CPUs too. *Zen 3

If you have an EXPO profile higher than the default, it acts like an overclock for your CPU. With a Ryzen 5000, going straight to 3200 is fine, but that was the sweet spot for a 3600 C16 running on two sticks of RAM. That setting won't work well if you have four sticks instead. People had to lower it down quite a bit, around 2933 or so, just to keep things stable over time.

Yes, that's the right way to put it, but here is the thing: I am not actually going to use XMP right now. I'm okay using 3000MHz because I think it won't make my computer slow down much at all.
