9070XT Steel Legend arrived yesterday - my last AMD/ATI card was an ATI 9700 over 20 years ago...
Hardware change was quite painless - downloaded latest ATI Adrenalin and DDU, unplugged network, uninstalled Nvidia components (multiple restarts), safe mode and DDU, 2070Super out, 9070XY back in, boot up and install Adrenalin sorted, plug in network.
It's a mother flipping Christmas tree flashing out the back of the case, so switched off the RGB...
Then started getting CSM messages, this was the less fun bit... I had no idea the hard drive needs to be in a different format to boot, so disabled CSM in bios and it turned into a bios boot-loop. hmmm... did some googling, re-enabled CSM, booted to command line and used MBR2GPT to convert it. Got some "failed to update reagent.xml" error, cue more googling... Realised this was just for some repair, so thought screw it, I'll give it a go. back to bios, disabled CSM and it started to boot into Win10. Got to the login screen and just stopped... I couldn't log in, the keyboard leds went dark and it wasn't working. Had an idea it would probably need to install some drivers with the UEFI change, so left it for a few mins and it all popped back to life. After a few reboots it all seemed good, ace.
Next step - Adrenalin is moaning about AMD Smart Access Memory disabled... back into bios and enable that... sorted...
All seems good. Probably should do a clean windows install sometime tho.
