All I did was flash my bios, then Load Optimized Defaults setting, boot to Ventura the sleep problom got solved miraculously. Then I change the bios settings one by one, make sure sleep still good. I think you can also use the default bios setting to test sleep, don't change anything. I'm running DDR5 6000, but I can not enable XPM, it can only run at 5600, about CPU temps, I was use Intel Power Gadget in Monterey, all looks good, I'm not install it in Ventura, because I can hear the fan sound and feels good, I'm 13900KF btw.
