Disable the graphis on the i9-12900K

[lgrip]

I have a very strange request. Can anyone to me how I can disable the graphics on the i9-12900K Processor?

If you have an add-on graphics card, you should be able to disable the processor graphics in the bios of your motherboard.

By default, most BIOS will default to disabling the Intel Graphics engine automatically, if an add-in graphics card is detected. It is still worth going into BIOS Setup to check this, should your BIOS not do this automatically.

I ran also CPU-Z on it,

So I just got the AORUS z690 Master gigabyte motherboard by Default the BIOS was set it enable on iGPU , I went and was able to disable it, makes the CPU temp go from 35c to like 28c in temp, I also tried setting it to auto it still had loaded it with the NVIDIA rtx 3070 master AORUS external 3D card, not sure I need the intel UHD 770 card on by default since I have that external 3D card, and all my current monitor and tv set are connected to my nvidia based 3D card, I have the AORUS z690 again which is a gigabyte brand motherboard all up to date with firmware to the current stable bios, and again it doesn't disable the built in 3D card which I think is a part of the i9 12900k processor if I am correct, when I first had set it up I did have the output using the DisplayPort on the motherboard but I switch it since, and no the bios will not disable it automatically on my system. My older gigabyte motherboard did not have a built in 3D card, or display ports it required the nvidia 3D card in order to display anything, so I don't know but it seems it does affect the cooling of the CPU not sure how much it matters, also I did try the UserBenchmark app gave the CPU a high rating after I had disabled the built in iGPU card, I don't know if it makes that much a difference really I don't notice much besides the fact that it seems like it keeps it just a little bit cooler with it disabled, I am using a CPU fan with RGB that has the dual fans on it, seems to work fine so far, for this processor, I only notice it hitting the 90c once it a while when loading games, but it seems to normally keep it around 50-80 I think in temp when loading most games, it seemed to hit the hotter temps with stuff like rending, max at 91c and no higher than that. using an Cooler master haf-700-evo case with my new computer system, also my older gigabyte has an older cooler master case.

also I had to uninstall the intel 3D drivers from windows 11, there was a problem where it didn't display on my main display at first, was able to fix it, and get the NVidia 3D card to display not sure why, but it worked after I turn it back on removed the intel 3D card drivers then went back into the bios and re-disable it again, so at first I was stuck having it to either enable or auto, auto setting in BIOS doesn't disable it, but seems to keep it turn on even if the NVidia 3D card in my system, so I don't know exactly what auto should be doing with it? the temp on the case right now is 32 to 34c it went up since I wrote this post, so I am not really sure if disabling the iGPU does much good, at first it seem to keep it around 27 to 28c but since doing stuff not even in video games the CPU temp went up, the GPU NVidia one reads the temp at 44c in masterplus app that comes with the case and all its RGB lights stuff, which has the CPU GPU display on the front of this case, that's what I am getting the cooling numbers off of. the 3D card fans don't run on the idle temp but only when it goes up a bit, same for the power supply its fan is based on the temp and run when needed I guess and from what I understand they only run when they are needed to cool stuff. since I last edited it the front is now displaying 28 to 30c in temp, for the CPU so I am not sure what to make of it, my older case seemed to keep the temp on the output display at 23c to 27c and it didn't go above that not sure if its case temp was accurate for its processor is a intel i7 and it used DDR3 memory and my new desktop has the DDR5 memory with RGB colors etc..  so it might be more accurate of a display, and I just don't really know what to make of its cooling numbers if its good or not with the iGPU disabled or if I should just keep it enabled again that UserBenchmark show that the processor ran better with the iGPU disabled but it's just a small amount I think I don't think I am home user gaming would notice the difference in the games at all. also, I got a gigabyte 27 type 4k display for this new computer so, I am able to play 4k games and use HDR settings on my new display.
