Spent many days, doing through guide slowly and trying tio double check everything.
OCAT shows no errors. So I am srill missing something.

My system: MAG B650 TOMAHAWK WIFI (MS-7D75) , AMD Ryzen 9 7900X, 32 gb DDR5 ram,
Not getting any OC logs on the USB after it fails.
Switched to OC Debug version, same issues, oplus no logs.
