I am having the same problem. On Asus z790 Hero. Once I turn AI overclocking off, the crashes stop. Something is very wrong with AI overclocking. I'm on bios v1202 now and same issue. Was working fine on bios v0816. Asus, please help!
Strange. My AI OC works fine since 0703. I have Z790 Hero. I am now running 1303. If you go into BIOS. What is your Cooler Score? The higher the score, the more AI calculate number of P Core at higher clock speed. If you are having issue, maybe manually defined the score lower. Set AVX offset 1 or 2.
Note: i have a delid 13900K. I was able to use SVID behavior: Best Case Scenario. Asus Multicore enhancement: Enable = Remove All Limit. during Cinebench R23, the power draw is around 260 Watt, and score around ~40500. You will need to play around to find what is optimal for your CPU, Memory and you silicon lottery.
