I've had this motherboard for over a year and havent had any issues. I've always had XMP active with no problems. I switched my cpu to the 270k Plus 2 days ago and ran XMP as usual and no problems until this morning. I woke up with my PC in the bios screen. I continue on as normal and I now get a Memory Overclock failure. Why would this be an issue now when I didnt change my RAM at all? My bios is on the latest one. My RAM is DDR5 7000 (PC5 56000)

Try running a memory test.
Or check to see if you’ve set the memory timings correctly.

Different memory controller on the new CPU, might not be as tolerant as the older one.

Update: Due to my cpu crashing and i had to reseat my ram, XMP works now. As for how long idk. Thanks everyone for their comments. Next issue is just getting Intel Platform Performance Package to work on Win10.

I'm on win10 so i can't use the Intel program that optimizes this chip

Are you subscribed to the extended support for Win10? Otherwise it's becoming a bit risky by now. Each month they are finding new security holes, but they are only patching them on Win11 now. Win10 doesn't get any fixes since last October anymore, unless you're on Extended Support. And even that will end this October for sure.

It's no problem to make Win11 look and feel like Win10, if you're worried about that. You can also disable any telemetry, AI features and whatnot. So the only reason would be some software that runs under Win10, but not under Win11, which would be quite rare indeed.

I agree with fatedust, more RAM stability testing is in order. You cannot just wait on crashes. When a game crashes, the instability is quite severe already. But there might be a slight instability going on unnoticed, which could ruin your installation over time, since it may silently corrupt files. Everything the PC does has to go through the RAM first. So every write to the SSD, it has seen the RAM before, and you want to make sure it's stable.

So I also recommend checking the RAM stability properly with TestMem5, see my RAM guide under 5), I explain there how to do this.
