Switching from APU to GPU - What Do I Need to Do?

Hi,

I have a Ryzen 5 5600G with integrated graphics, I've recently purchased a cheap graphics card (radeon rx 580 8gb) that I now want to use.

Is it just a case of installing the card and then downloading the required software/drivers, or do I need to do something else in order to use the GPU instead of the APU ??

Thanks

    Make sure your power supply is grunty enough to run the GPU
    Make sure your LCD monitor is attached to the GPU not the motherboard

    That's basically it. You shouldn't need to tweak any settings in the BIOS either.

    Thanks for the reply scrimshaw.

    I've got a Thermaltake 700 Watt power supply so hopefully have that side of the house covered.

    Glad to hear it's as simple as that, after reading a few things on the net I'm obviously over-thinking it now :-)

    Looks like the RX580 also has an 8pin connector for additional power so don't forget to connect that to the psu.

    Pretty sure you also need to switch the iGPU off in the BIOS ….

      Oh no, I've got to do what now? lol

      I need to turn something off in the UEFI ??

        This is an antiquated thing. You will need to do that in the old days but with a modern motherboard and Windows 10 it's basically automatic, you don't need to manually switch off the IGPU.

          Thanks again, I'll keep it simple plugging it in, downloading the drivers and seeing how I go.

            @shutuptakemymoney101: I will rephrase - If you don't switch it off in the BIOS, it will still claim an amount of RAM to reserve ;)

              @7ekn00: Is that likely to be an issue? Presumably if I switch off the APU in the BIOS then if the GPU stops working for any reason I can't just plug a monitor back into the motherboard to troubleshoot?

                @shutuptakemymoney101: shrugs, can be up to 4GB of RAM wasted ;) Mines currently using 4GB of 32GB on a 1080p screen :P

                Task Manager > Performance Tab > GPU 0 > Dedicated GPU memory usage

      Na. You just have to make sure your monitor is physically plugged into the graphics card, not the mainboard as at present. Operating systems are a LOT smarter about these things than they were 20 years ago.

        How does Windows know which GPU you want to use?

          It is continually asking on both outlets "Is there a monitor there?". It sends the graphics signal to the one that answers "yep, Im here".

    New GPU all plugged in and working thanks for everyone's input, Task Manager is only showing dedicated and shared GPU memory usage so the APU doesn't seem to be impacting on anything at all.
