I'm using an R5 5600 and I've got 32GB of Adata XPG RAM rated at 3600MHz, but whenever I set the speed to anything above the automatic 2666MHz—whether it's through an XMP profile or by tweaking it manually—my system just refuses to boot. What might be causing this issue?

According to AMD's specs, when using four RAM sticks, the maximum speed is generally around 2933MHz for the 5600. So, if you're trying to boot with four sticks at 3600MHz, that's likely why your system won't start. You could either reduce the RAM modules, manually tune it, or settle for lower speeds.
With four sticks running at 2666MHz, you're hitting 5302MT/s, which might just be too much for your CPU to handle. That's probably the reason for the boot issues.
It sounds like your RAM configuration might be pushing your CPU's memory controller too hard. The Ryzen 5 5600 can usually handle 3600MHz without too much hassle, but sometimes extra modules can complicate things.
Have you checked if your RAM is listed on the motherboard's QVL? It’s important to ensure compatibility between the components.
Yeah, it's an Asrock 550M and it supports Adata RAM, so I think compatibility isn't the issue.

Actually, a lot of people have successfully run 3600MHz on the Ryzen 5 5600 with no issues, so it might just be a specific setup problem.
