have you selected no free drivers on boot USB live Iso ?

if you do not get display manager you should check in

sudo journalctl -b0

have you selected no free drivers on boot USB live Iso ?

I have.

I have tried both Boot with open source drivers and Boot with proprietary drivers however the result is the same. Previous inxi output was from ‘proprietary’, here is the output after booting with ‘open source’:

others questions about CPU & Memory & Motherboard
you should use 3200/3000/2933/2800/2666/2400/2133
better speed memory if possible 2666 → 3200

have you underclocked you CPU Volt ?

CPU and motherboard are as you see. Memory is Crucial Ballistix 3200 MHz (BL2K16G32C16U4B). Never over/underclocked the CPU.

Without any changes to the hardware config ubuntu-mate-21.04-desktop-amd64.iso booted and installed without issue (even had sound in the installer). So I am going with that, at least for now.

Thanks
