    Hey everyone, before I start I want to apologize for my ignorance on the matter. 7700HQ with a 1070 here, undervolting the CPU works fine, but I was curious about iGPU Unslice and undervolted that too to -70.3mV, however nothing seems to happen. Temps are the same. Aside from the fact that I have no clue about what I am doing, is anything happening at all in my GPU? Does that setting even do that? I just have to undervolt more or is that setting pointless for me? I read somewhere that its downvolt should be coupled with the System Agent one as well, but again I have no idea. Thanks!

    Not sure about the iGPU unslice but I have it set the same as the iGPU voltage offset,

    With the newest version of the ThrottleStop the System Agent is isolated from the iGPU voltage offset so they are two separate kinds of settings,

    Also undervolting the System agent too much will cause the Memory controller to be unstable giving you freezing / BSOD so don't go too far on that one.

    Edit: by the way when the iGPU is at 100%, undervolting the iGPU will lower the wattage by a huge portion (from 10W lowered to 8W on 8750H). But at idle, the benefit is not so much as at idle the iGPU is already very low, not even closed to 1W.
