well i enabled this states and this happened also on the UD7, vcore on IDLE gets higher as its on 1600, when it gets to 5000 goes to 1,416

i have vcore set on bios to 1,41
LLC 75%
VRM 350
PLL 1,7
VTT 1,08

all C states enabled + EIST




and this is browsing making the chip go out of C states




plz note the dif on vcore, without C states you will never see 1,424 on IDLE but enabling them YES

cheers

In order to get the idle vcore to drop when Cstate drops mhz to 1600 you need to enable offset vcore. I have been doing extensive testing with the offset vcore the past few nights and will post my results as soon as I am done.

that will be insteresting last time i try to on giga i gave my chip like 2 volts lmao

Yea, I have it working great on my secondary rig (P8P67LE + 2600K) it idles at 1600Mhz @ 1.0v and full load it goes up to 3800Mhz @ 1.295v and is LinX maxmem stable.

Now, first few trys with my main rig have my load voltage at 5Ghz @ 1.62v. I am using the (-) setting to reduce the offset but the problem is if you use a (-) to reduce load voltage it also reduces idle voltage by same amount. Its a work in progress but will post up something once I get pretty comfortable with it.

jeeeeeze 5Ghz @ 1.62v !!! aint that too much or was a mistake ?

good luck on your tests

If you read this guide on ROG Forums for offset voltage (same place as guide you posted above) it states you enable offset voltage, then need to boot into windows and look at voltage reported by CPUZ ROG edition at load. Then you use the (+) or (-) offset to raise or reduce the voltage to get it as close as possible or dead on your known 5Ghz stable vcore (or whatever speed your running). The 1.62v was the voltage automatically set by bios so I used the (-) offset to bring it down from 1.62vcore to my required vcore of 1.49vcore (I know, bad chip and I still havent found a good one) which is a setting of (-) 0.13 (1.62 - 0.13 = 1.49vcore)

I still don't have it 100% figured out but like I said, I'm making progress. I believe my problem now is my idle voltage is unstable because the stock idle vcore at 1600Mhz is 1.00v where the offset of (-) 0.13 to be stable at 5Ghz now gives me a idle vcore of 0.87 (1.00v - 0.13 = 0.87vcore) which I believe isnt enough. Remeber, the amount you add or remove will apply to both idle and load vcore so you need to find the perfect medium I believe.

I still dont understand how the MB or CPU determines the starting vcore (1.62v) to start off with and that is what I am trying to figure out. You can select 3 different settings to enable offset vcore, "Manual" "Standard" and "Optimized".

hmm,, so what's the difference from setting 1.62v in BIOS to using AUTO and the offset of -0.13v?

I've read the thread over at ROG forums, and if we are setting the voltage near as dammit to a stable clocked chip then what is the difference to running the voltage on AUTO = default voltage then applying the offset to achieve what you can manually set?
I know there has to be some common sense there some where, someone able to explain this please?

If I understand what your asking, you want to know why use offset vcore vs just manually setting the vcore?

Ok, lets say you are using a 24/7 clock speed of 5Ghz that is LinX stable at 1.45vcore. The reason offset vcore is good is because if you enable cstate, speedstep and use offset vcore your processor speed at full load will be 5000Mhz at or damn close to 1.45vcore but if you setup offset vcore correctly when your processor is idle it will drop speed to 1600Mhz and will drop vcore to 1.00vcore or close to that depending on your offset therefore reducing temps and power usage when pc is not being loaded or in use. When you run a 5000Mhz 24/7 speed with 1.45vcore manually set not using offset vcore your processor will still run 5000Mhz at full load and drop to 1600Mhz at idle but your vcore will always stay at 1.45vcore at both full load and idle, so vcore doesn't dynamically adjust with CPU speed like when using offset vcore.

Hope I answered your question without going to in depth.
