[GA-Z87X-UD4H] Save $ On Electricity, But Not Interfere With Gaming?

post #1 of 12
Thread Starter 
Link to my motherboard - http://www.gigabyte.us/Motherboard/GA-Z87X-UD4H-rev-1x#ov

I don't want to remove my overclock/downclock and I'm completely unsure as to what the C-States do and what to do once I am in Windows 10.

My electric bill is getting quite high, and with the summer around it's getting hotter which will only increase costs. I want to keep my overclock, but still want my computer to run at max speed while I am gaming or video editing. I just want it to eat up less power while I am watching videos, posting/reading forums, and talking to friends on Steam/Discord.

I don't really know where to start on this because I am only familiar with overclocking, and most overclocking guides don't go into the specifics of CStates or power options in BIOS, just stating to turn them off because they'll do (X).

I read some of this - http://www.hardwaresecrets.com/everything-you-need-to-know-about-the-cpu-c-states-power-saving-modes/ but don't really know which to go for. As I said, i want to maintain a stable overclock, just use less power when I am not gaming/editing.

Reading this post: http://www.overclock.net/t/1494449/do-you-have-intel-c-state-disabled-or-enabled/0_100#post_22560734

Suggests just enabling C6/C7 state in BIOS. Though I have no way to measure the idle voltage. Even if the CPU is running 100% speed, the voltage won't kick up until there is a load. What is considered "idle" and what is considered a "load"?

Idle is sitting at the desktop with no apps running, load is whatever type of application you are running, I.E. gaming load or rendering load. When you first boot up the PC with just CPU-z running , what is the reported vcore?

So then if I am watching an online video while talking in Discord(Hardware Acceleration off) on my 2nd monitor, it won't be "Idle" so it'll then be using max voltage? I do not have CPU-ID installed atm, just HWM. I can install it in a bit if that's the only way to tell.

Vcore is generally dependent on the speed of the highest clocked core. If your most heavily loaded core is running at 40% load, voltage and frequency should be somewhere between idle and load values.

My core voltage currently says 1.266 V when I have C6/C7 state enabled. I guess it's not doing anything?

Yeah that is way high for idle. Are you using fixed voltage in your UEFI settings? You need to use offset voltage instead.

Not sure what UEFI means? I have a set voltage in my BIOS, and all the "offsets" are grayed out, always have been.

I enabled C1E, while also having C6/C7 enabled -

I don't think they're working still.

Also not sure what this is showing - RealTemp

UEFI=BIOS.
Enable intel speedstep and ensure windows is set to balanced power profile.
Core Voltage needs to be set to "adaptive" or "offset", not "manual" or "override" in BIOS.
