Well, I thought everything was all good with EXPO on the 0606 BIOS, but… I started playing the new Indiana Jones game and it would just randomly crash. I turned off EXPO and when back to AUTO and it plays flawless now - no crashes. So, my next attemp...

No, not yet. I was waiting to see what the general thoughts were here before trying 0706. 

I am on ROG STRIX X870E-E GAMING WIFI board (Non-Hero)On the default board drivers EXPO would not post. I didn't try EXPO again until 0606 BIOS. So far, so good.

Following up on this issue...I updated to the 0606 BIOS today and loaded the default EXPO profile. I am happy to report that I booted without issue and Windows 11 is showing my RAM running @ 6000 now!I have not tried 0706 - I'm going to hold off for ...

Oh nice. Do these BIOS fix the EXPO issues officially now? Or do you still need to move M2 drives around as well?
