Yeah, just tested as well and my X670E Master still has the stability issues, especially on boot....

X670E AORUS Master - F9c​ does still have the same old memory issues causing freezes during boot and while running.

I am currently testing the newly released Version F9C for X670E AORUS MASTER. While the notes only specify support for new CPUs I hope the increased AGESA version or something else improves the spotty and crashing memory stability....

So far the X670E AORUS Master - F8​ bios has been terrible compared to the F8H beta which also wasn't great, but less bad than this. Freeze during boot, sound glitches and memory instability are all issues.

I am still getting occasional memory issues, like memory corruption when in-game. This current bios is better, but Gigabyte really needs to look into their stability.

...

Yeah failure to boot a couple of times. Once the networking just stopped.
I'm thinking it could be PCIe lanes​ or related.
While troubleshooting issues I had Nvme drive that acted weird and effected the rest of the system, I figured it was broken and I took it out and that seemed to fix...

I've had weird behavior from F8h too sadly. It's way better than F8c but still rather unreliable in weird ways....

So far, for 1 day, the F8g bios for X670E AORUS MASTER has been working really well for me. None of the BSODs or weird USB issues. Boot is faster as well.

Actually having some usb issues on my X670E AORUS MASTER as well, and the newest F8c is not an option due to bsod issues so I hope Gigabyte release a proper USB error free bios here too.

Thanks for posting this. I've been having the exact same problem on that board and F8C, not stable at all....
