AM5 X670 woes!

Anyone running AM5 having any issues while running EXPO, I literally can't enter the BIOS without clearing CMOS and boot time is usually north of 40-50 seconds. I've tried updating my TUF X670 WiFi to the latest BIOS but hasn't helped.
CPU is a 7950x, the system performs great when it's finally into Windows etc but these Boot/BIOS woes are getting very annoying starting to wish I'd gone Intel or stuck with AM4

What is your RAM? Is it possible that the EXPO profile speed is too fast for your CPU's memory controller? My RAM is rated at 6000MHz, but my CPU is only capable of running it at 5600MHz.

Hi mate I'm running 64gb Kingston Fury Beast 6000mhz, it does seem to boot faster and let me into the BIOS more frequently running at the 3600 mhz stock speeds but I would have thought a 7950x could handle 6000mhz no problem.
As I said it works fine in Windows but the long boot times and problems getting into the BIOS are very annoying when you want to tweak settings etc.
Probably an early adoption issue that will be fixed later down the line I suppose

Have you waited for like a couple of minutes for memory training? I wouldn't even keep a platform if it could not run the specs I wanted, 3600 is such a performance loss.

Yeah I've waited for memory training etc, it's not really a big deal on the boot times and it runs like a dream with EXPO enabled at 6000mhz in Windows. Boot time is a fair bit slower than my previous AM4 build. Getting into the BIOS is a pain though. Guessing future BIOS updates will improve this over time. I feel like it's memory training on every cold boot, I'm sure they'll have a workaround in the future. Just a small annoyance atm
