Haswell and power saving

Well i guess it depends on your motherboard then. Might just be the asus ROG boards that don't downvolt in manual mode?
 
The link i posted was a guide on the asus republic of gamers website written by one of there guys. That is defiantly how all of the rog boards work at least.
 
I have all the power saving stuff turned on and the trick was to install real temp and then click settings button and untick "disable turbo" and then it worked. Had me stumped for hours though. Not sure why windows was disabling the turbo mode.

In bios on turbo settings i set mine to manual and then specified the oc multiplier, the uncore was set at 3.8ghz and oc at 4ghz.

I left the vcore on auto and eist and other power saving on auto. I set the ram voltage manually to 1.65 and set xmpp profile 1 and manually set the latency.
 
Ok so if you change the c state from auto to enabled, the processor does enter the low power C states when in manual mode! These seem to use even less power then the standard low power modes at default settings.

Sorry for the confusion everyone

Either you are wrong or you can sell the board to asus for a tidy profit and they can reverse engineer it!

I'm definitely not wrong.
Unless CPUZ is randomly giving me a low Vcore (But changes when I do something)

My board is definitely in manual as I've never found offset to work with my Maximus IV Extreme, so I never tried with my VI Hero

Like I said ;)
 
Strange, i have all power settings on in the bios
and balanced power setting set in windows
with monitor always on and pci express link max performance.

and my multi and bclk drop ;) also my voltage drops to insaine lows 30/31c idles :D @4.5ghz :)
and i did not have to set offset voltages i have manual voltage set in bios and still my vcore bounces about depending on load right down to 0.7v :D

Proof ;P

At stock, yes mine does drop clock and voltage. Unfortunately i cant test at oc settings as it's proving to be a bit of a ******* to overclock.:D

Anyone explain to me why AIDA cpuid does not change while realtemp does? Looking at ViRuS2k screenshot it shows that the aida cpuid should change.

Mine never goes below 2800ghz and the voltage does not appear to change much. The frequency and temps on realtemp change and that's it. So i am not sure now.

bottom one is the one in load.

Im thinking of going to 4.4ghz with 4.2 uncore.

I found mine to be an arse, in that it took more than five minutes. I remember when **** was as simple as uping an fsb and voltage...
 
Got it to boot into windows now, (45x100 bclk) voltage doesnt drop at idle. Im using fixed vcore. All other settings on auto, balanced power profile and c-states, speedstep etc enabled.
