disable integrated graphics?

post #1 of 6
Thread Starter 
I have a 3770k and i was wondering even though there is no load if disabling the integrated graphics would create a drop in temp?

i have mine disabled as i dont need it, i am not sure if when i did it made that much difference in temps as temps here where i live fluctuate.
one thing tho whilst i would leave it disabled if you have a discete graphics card which i do because if my graphics card dies i have a back up. so if you dont have a back up card by leaving it on means you can still use your rig if the card dies.

I think most MOBOs will default to integrated graphics if no other cards are detected even if it was previously disabled. Also, enabled is default in Bios so if worst came to worst you could clear the CMOS to get back to factory defaults.

No idea if it lowers temps. I was actually wondering this too but in my case I was wondering if it would put less stress on the CPU making it possible to overclock higher or use less voltage.

I'm pretty sure the CPU itself disables or gates the iGPU if it isn't in use, no matter what is set in the BIOS. Given the aggressive power saving in the new chips I don't think they'd be putting any power into something that wasn't being used. So I doubt it would make any difference. Easy enough to test though. smile.gif

I have seen no difference in temps on/off.

It's definitely fully shut off if an external GPU is being used.

Intel spends billions on improving power efficiency, I wouldn't worry about the iGPU using power unnecessarily.
