no, Dual graphics means, that I can choose, which GPU is rendering image on my screen without restarting the system, but they do not work at the same time..
there is no such setting in BIOS to disable iGPU, i can just choose, which I want to prioritize for boot
I tried this now.. Vega8 just disappeared from Radeon Setting, but i can't install newer driver for my RX560, which has only 17.7 driver installed by drivers for R3 2200G.. When I try to install 18.3.1, error " couldn't find drivers for your system" appears.. I don't like the fact that this amazing processor prevents users of AMD dedicated graphics cards from using latest drivers
funny thing this manual you found.. because in my bios there are only two settings.. PRIMARY VIDEO ADAPTER and UMA FRAME BUFFER SIZE.. the one, which should disable iGPU is missing
this from AMD: Radeon™ Dual Graphics FAQ | AMD
From the link above:
AMD Radeon™ Dual Graphics is an innovative technology exclusive to AMD platforms that allows AMD APUs and select AMD Radeon™ discrete GPUs to work together. When combined, the platform delivers stunning quality and performance capabilities that are better than either device alone.
Does that explanation from AMD say it DOESN'T WORK TOGETHER!. Anyways, the link says Dual Graphics only work with A series APU. Unless they made the Ryzen APU to work with Dual Graphics. I don't know. I was just going by your original post about having Dual Graphics enabled.
As for the Manual, I went to MSI Support in inputted your Motherboard (MSI B350 Tomahawk) and downloaded the Manual to check the BIOS settings for your board. That is the picture I took from the PDF file of the Manual. Let me download it again and attach the .PDF file to this post. You can check it out yourself and save it for future reference. Unless your Motherboard Make & Model is incorrect.
I attached the B350 Tomahawk MSI Motherboard Manual to the previous post. But it is invisible because it needs to be approved by one of the moderators. The post is invisible because of JIVE to protect the Forum from malicious website links or downloads.
I also showed you that you are wrong about what Dual Graphics means in that same post.
elstaci is right on what hes saying. Do a bios update on your motherboard I suspect it needs it if the duel graphics enabling & disabling section on first priority boot. As all motherboards between Craptel & AMD are the same. I supect you havnt done the bios update to properly utilize the new micro code built in. As if your using the RX 560 as a primary card it should automatically take over & load up the driver & should be realistically be able to diable the integrated graphics options.
I have manual for my motherboard, but theory written in the manual is one thing and reality in bios is the other.. As you can see from my screenshot, the option to disable iGPU is missing, so it looks like a bug of current version of MSI bios 😕
yes, I made a mistake with Dual Graphics.. the technology I meant is Switchable Graphics.. Because both dGPU and iGPU are enabled, and I can switch them by plugging HDMI cable in the motherboard or in the graphics card.. So it should be possible for AMD to enable this feature in drivers on software level, as it was back in time of my first notebook with Llano APU..
