OC'd 3930k not changing when idling

post #1 of 19
Thread Starter 
New to OCing. OCd my 3930k to 4.5hz on a Rampage IV extreme with offset voltage. I think I am doing something wrong because under load the voltage is at 1.33 but at idle cpuz says it only goes down to 1.28v and the clock speed never goes below 4499hz. From reading other people's offset OCing results I was under the impression the CPU voltage and speed should go down a lot more under idle.

I followed Raja's offset OCing guide. I set everything to auto booted to windows, restarted and changed to manual mode, set the CPU to 4.5ghz left the voltage on auto, booted to windows and reset, then offset the voltage from the voltage the motherboard assigned it for that clock speed. I set the PLL to optimized and the load line to high because it was downclocking and crashing when under 100% load when the load line was set to medium. I left all power saving options enabled and OC' by all cores.

Wait, so both Enhanced Intel SpeedStep Technology ("EIST") and CPU C1E are enabled, you're using a manuall-set Offet Voltage (it's not set to Auto), but yet it's still not dynamically adjusting either of these based on the load?

Yes Sir, that seems to be the jist of it. I will double check when I get home from work to confirm but before I started I reset bios to load safe defaults and never turned off any power saving features myself after that.

I set the multiplier to 45 with auto voltage then booted to windows so the motherboard would set its voltage. I then changed the voltage from auto to offset and began decreasing the offset until I got to -.050

That sounds like an unnecessary step to me and it sounds like the writer of the guide doesn't know that it's easier to set voltages than that.  Whatever works, though, I guess that's all that matters (if the end result is the same, I mean).

 

Still, the motherboard doesn't wait for Windows to load to set the voltage;  it does that as soon as the motherboard itself reboots.  ;)

 

Anyway, where did you set the multiplier?  Was it in the Extreme Tweaker tab?  Or, was it in somewhere like Extreme Tweaker\ CPU Performance Settings >, or even Advanced\ CPU Configuration\ Power Management Configuration >?

maybe there is something in the background that is running? Fire up RealTemp or Taskmanager and see what (if any) load there is on the CPU when idling.
Before when i have set Windows power management to 'performance' instead of 'balanced' the idle voltage increased ever so slightly, but this is only gonna be marginal - worth mentioning tho

EDIT - also worth mentioning to Set your VTT and VCCSA voltages to 1.1 and 1.15.

On the Rampage Mobo's, if left to Auto,they tend to over volt them a lot..

Dunno if this will help but on my Rampage IV Extreme, setting C states to "Auto" will actually disable them. Make sure these are set to Enabled, Auto doesn't always cut it.

So Set C1E to Enabled and C7 to Enabled.
I recommend turning C3 and C6 off when overclocking with offset as these are known to cause idle BSOD

Also, on stock settings on the R4E, the CPU will NOT downclock/downvolt on mine.

I won't be home from work until tomorrow night to try out your suggestions but in the mean time: the guide i followed said to leave the voltage set to auto when you set your clockspeed, restart and change to offset mode and start setting your offset value. I did manual before so I know what voltage my CPU is stable at. So should I change the voltage do that stable voltage and then set my offset value? May sound confusing but basically the mobo will automatically set my CPU voltage to 1.42 when OCd at 4.5ghz. I have been doing a negative offset off of that voltage and it runs at 1.28v at idle and 1.33 under load.

I still have a question that hasn't been answered:

 

Where did you set the multiplier?  Was it in the Extreme Tweaker tab?  Or, was it in somewhere like Extreme Tweaker\ CPU Performance Settings >, or even Advanced\ CPU Configuration\ Power Management Configuration >?

 

Please don't feel bad for missing it because this happens to me every day here on OCN, and I don't know why.

If you want it to down clck in windows. Make sure in Control Panel > Power Management > It is set to Balance. If it is on performance it will not down clock. Thanks
post #10 of 19

Mine downclocks just fine with it set to High Performance.  It even downclocks with both the Minimum and Maximum Processor States set to 100%.
