I'm facing a challenge with my system where the RAM isn't reaching its expected speed. I'm using the MSI X870E-P WiFi motherboard with G.Skill Ripjaws S5 (6000MHz) and an AMD Ryzen 9 9950X3D processor. I have also updated to the latest BIOS. Normally, when I boot up without enabling EXPO, everything runs smoothly, and when I enable AXMP in the BIOS, it recognizes the RAM at 6000MHz. However, after a restart, I get stuck on the orange light and can't boot unless I clear the BIOS settings. I've used this RAM without problems for the last couple of years on an Intel i9-13900K with XMP 3.0, so I know it works. Any suggestions?

It sounds like you've hit a typical issue with using four sticks of RAM; having four modules can sometimes lead to difficulties in achieving higher speeds. Your previous setup with the Intel processor must have had a strong memory controller, which is why it worked fine there. You might want to try using just one stick per channel or consider lowering the RAM speed a bit to see if that stabilizes things.

That might be why I also struggled to get 256GB of RAM working in my server with EXPO. I eventually stopped trying to fix it since I wasn't too concerned about the speed. It's frustrating for sure!
