No, not really.

Just Disable it in bios thumb.gif

The only reason I can think of to leave it enabled is if you use Intel's quick sync. MSI afterburner is a program that many OCN users have installed and it can make use of this feature.

I've got Afterburner installed. How does it use iGPU?

Quicksync and stuff like many screens. The iGPU can power like three of it's own after GPU slots are full.

quicksync can be used for low quality but low cost encoding. MSI AB and a few tools can use it to encode gameplay into a video after capturing screen

Well I guess if you want to utilize the transcoding features of the iGPU. Otherwise it must generate more heat.

Had a few bluescreens where i didn't expect them (the profile that i used for 2 months last year at 1.235vcore without so much as a whea just 124'd while live encoding gameplay with x264 - but it was at 1.24v) but not sure if it's just down to not having big enough sample size (always unstable but never tested for long enough?), or slight degradation. I don't think i should have seen any hard degradation, i've been conservative with temps and volts. I'm more tempted to use the single-fft-size method with prime 27.9 though, given the harder vcore tolerance and the fact that i'm still, after 6 months of usage, getting odd fails on long-established profiles

Funny you should say that. I had the same thing happen to me yesterday with my stable 4.5Ghz profile that I was using for 4-5 months. Only difference is that I switched out my GPU yesterday and looks like my PSU can't do both the 4.5Ghz clocks and the GPU as well. 12v rail drops like mad, so I had to drop to my 4.2Ghz OC because I got a 124 BSOD.
