Overclock stays at constant voltage

Hello! I have overclocked my intel 5820k on my MSI x99 SLI motherboard. I have clocked it to 4.2 on 1.28 v. The problem is that it stays at 1.28 v constantly. It never ramps down when I'm idling. Anyone have any ideas of a setting that I can change?

I know Asus has something that does this. I think its called offset mode or something like that. Not sure.

Thanks!

Edit : The voltage and overclock is just temporary, I will experiment more after

if you used a guide to set your oc in the beginning it had you turn off all the power saving features and to run as hard as possible to make the oc more stable. Turn the power saving features back on and it will ramp down. Your voltage is probably set to manual as well set it to auto.

I'm not 100% certain on that motherboard but it would be better to leave core voltage on manual. On auto the motherboard may decide to push it higher than you planned on. There should be a setting somewhere for eist which should be enabled. That's intel's speedstep that downclocks the cpu under low load situations.

Check here, it's a screenshot of the click 4 bios with the eist option under overclocking. Check to see if it's enabled or disabled, if disabled then enable it.

Here's the site that came from with an in depth look at the click4 bios with pics.

Also make sure to check power settings options in windows and see if under "cpu" if it's set to run 100% at both min and max. That could be preventing it from idling down. Balanced power plan typically offers min 5% and max 100% for the cpu.

Thank you for the help! But i was hoping to avoid auto voltage, as I have been told it is not always the best when overclocking :)

Thank you for the help! I have checked, but both eist is enabled and also the balanced power plan (with 5% as lowest). So I dont really know what to do now..

What program are you using to monitor vcore? I'm wondering if it is allowing it to drop down but maybe not showing in the software. I'm using a different cpu/motherboard (still intel) but for instance cpu-z shows my manually entered vcore all the time. No change. Watching hwinfo64 I can see my vcore lower down as my multiplier drops from 45 to 8 in real time.

Thank you again! I installed HWinfo64. I dont know what multiplier means, but in the program it says : CPU Status - VID : 1.1985 v (which is what i have put it to).
