Hello,
I have a HP desktop computer with HP Erica 8643 Motherboard and I am trying to disable the iGPU (Ryzen 5 3400G) because only 5.91 GB of the 8 GB RAM are being used, but I cannot find any way to do this. I am on the latest BIOS, F.30.
Does anyone have any suggestion please?
Thank you.
Model number: TG01-0019na
Part number: 1D4A6EA#ABU

Hi:
Even if you were able to disable the onboard graphics (which isn't possible), your PC was designed that way on purpose to have such a high reserved memory.
HP released this document a while back, which explains the memory shortage...

This seems to only apply to models with AMD Ryzen 3xxx processors.

Thank you very much for the reply and accurate information.
That is very unfortunate for me to find out, as I do not need at all this 'design', or how they usually call it, "feature".
Very disappointed I must say. Thanks again for the help!
