esmith1966 Posted January 31, 2022 Share Posted January 31, 2022 Spent the weekend swapping CPUS to/from two identical Asus z-390F boards and a z-370 aorus gaming 7... Both CPUS's were in working systems. These are an i3-8100 CPU 3.60GHz and an i9-9900K. Was able to install monterey etc with the i3-8100... Had extreme problems doing the same with the 9900k... The system would freeze and hard crash... disk reads would be off... during boot ssds would be labeled as unreadable... changed the BIOS multiple times... the 9900k would work one second and then the system would freeze the next... The final system I used was stripped to a bare bone systems using only igpu... I had been using an RX580 board or rather boards... _________ Has anyone encountered a situation where a formerly working cpu suddenly becomes error-prone...

esmith1966 Posted February 1, 2022 Author Share Posted February 1, 2022 The CPU is now in the Z-370 board... I have two working EFI's in other systems that "dont work" on this board... I alternately get the following screens with igpu... Unsure what needs to be modified in the EFI folder... Link to comment Share on other sites More sharing options...
