Steps to change from Nvidia to AMD GPU

[keithy]

@Echoa

just be careful with some of these connectors. They like to make them shotty at best sometimes which can become a fire hazard fairly quickly. There is also the issue of if the molex/sata on the PSU are really up to the task or not

You’re right. I would just get a new PSU if this was a high end GPU with high power requirements

As its not and is supposed to be relatively low power i think it’ll be OK

Thanks

Youre call, Ive had a GPU literally burst into flames in front of my eyes from a questionable PSU. You also cant sure if the connectors you bought can actually handle what they claim, even a lower end GPU can pull enough current to melt wires not actually able to handle what they claim.

Project temporarily aborted.

8-pin GPU PSU connector not compatible - need adapter

post a picture of it, 8pin PCIE plugs are universal except specific OEM designs. Its a standard for ATX PSUs so its either PCIE or CPU plug

Thats what I thought too. it has 2 x 8 pin connectors. Both different keying. One fits the CPU connector just fine. the one has different keying and I thought was for PCIe. It is a 4+4 cable not 6+2 however.

the keying of neither 8 pin connector would fit the GPU

This is the PSU:

I’ll try and take some photos

Thats the wrong connector, that is for CPUs.

Your PSU should have 2x 6+2 pin connectors you dont need adapters
PCIe (8/6 pins) 2 1 x 550 + 100 mm - attached

you have enough connectors for any single GPU configuration. Your PSU is fixed cables so no way theyre lost

check before hand /etc/mkinitcpio.conf if no trace of nvidia there

[keithy]

Your so right

I’ve found the right cable now hidden in a tangle…

How embarrassing.

Thanks for putting me straight.

I thought the drivers was going to be the difficult part

@keithy

How embarrassing.

Thanks for putting me straight.

it happens lol

[keithy]

Thanks,

the only nvidia line in here was already commented out

[keithy]

Even more embarrassing if I told you how many decades ago I built my first PC. So I won’t

[Echoa]

i accidentally mixed cables between 2 modular PSUs once and literally burned 2 sata ports on my old motherboard. things happen lol no need to be embarrassed

[keithy]

Up and running. Thanks everyone for your help

All looking good, except no option to login to a wayland session.

I’ll figure that out tomorrow

Cheers

[Echoa]

the wayland session is just called “gnome”

if you only have “gnome on xorg” its because wayland was disabled in the GDM settings.

edit /etc/gdm/custom.conf

the top lines should look like this

[daemon]
AutomaticLoginEnable=False
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false

[keithy]

Thank you again

Thats fixed it

[ricklinux]

I brought this up already. I guess @keithy missed the right cable?
