PC Drivers & Software

[C0ntr4b4nD]

Hi there,

I'm using a dedicated GPU(Sapphire PULSE RX6600XT). Today I boot up my build and realized the GPU is not outputting the images. Then I tried the onboard output with a DVI cable and it worked fine; at least it started displaying stuff. After checking the AMD software I found that the driver itself has detected RX6600XT, but it prioritizes the apu and refuse to use the gpu. I tried to boot the PC without plugging the DVI, just to found out that nothing was to be displayed, and when I plugged the DVI in, it worked. Re-install of AMD software did not solve this problem. How can I let the driver use the dedicated GPU?

Thanks in advance.

You will probably have to go into bios and set it to use the 6600..

Thanks for the reply.

I have checked the bios, but the default graphic output was set as EXT; I guess that means external GPU. The BIOS setting seems to be fine. I am at my job so I can’t provide a screenshot, so here’s the spec of my MB:

Asrock AB350M-HDV (the bios is the latest one)

Hi. After fiddling with some settings on the BIOS, finally, I managed to set GPU as the primal output source! Thanks for the insight!

I'd like to share how I changed settings: 

Advanced - AMD CBS - NBIO Common Options - GFX Configuration - Integrated Graphics Controller - Diabled.

Still, it is unclear why the BIOS suddenly stopped using the dedicated GPU. Anyway, your advice is much appreciated! Thanks a lot!
