Correct!

Could I get some advice/perspective here? I have been messing around with my overclock lately and here is the problem. I can run 4400 and pass stress tests at decent voltages but when I am at idle and just doing small demands I get a lock up.

The only way that I have been able to run stable is to disable EIST and all C states.
Of course this means I always run @ 4400 and am feeding it 1.31v in BIOS and also that is the voltage showing up in CPUZ...no load...manual setting.

I don't really think that my present setting is harmful but would like to know why I can't use the energy saving features and not get screen freeze. I have removed my graphics card so that is out of the equation and my ram is error free in memtest and runs at 1600. When I enable energy features it makes no difference between manual and offset....still locks up at idle speed.

Am I doomed to run 4400 non-stop in order to get a stable rig ?

The only one you should have to disable is C3/C6, which is the one that lowers voltage at idle. Known issue that it can be too low for some systems, causing crashes.

C1 & EIST are recommended left on, and shouldnt affect your stability. That will allow the cpu to downclock to 1600, but your idle voltage won't drop to below 1.0v.

Ahhhh, thanks for that keto. I will enable EIST and C1E

Ok, I have now enabled EIST And C1E. The speed does drop to 1.6 GHz but the voltage remains at 1.312V. Is it not supposed to drop to about 1 volt when @ 1.6GHz ?

edit: Got it now...forgot to change from manual to offset.

Read my post again. C3 and C6 PREVENT the voltage from dropping. It's a bug, can cause crashes like you are seeing, due to insufficient voltage, ie., it drops TOO low. Doesn't do it for everyone but it is quite common.

Sorry for being so dense but now I am really confused. In your previous post you said to disable C3/C6. I did so and ENABLED C1 and EIST. I also switched to OFFSET mode...put LLC on high.

Now I drop to 1.6 and my volts at idle are 1.00/.992. Is this not what I am after?

and +Rep for your help

I wasn't aware that C3 and C6 dropped the voltage, to my understanding it's offset voltage combined with C1E and EIST that does it, C3 and C6 have something to do with sleep I think, it's just another safety feature.

So, do you have any pointers for my "lock up" @ idle ?

what are your BIOS settings as of now? If you're running Offset then set C3 and C6 to disable, if you're running manual voltage run C3 and C6 on auto and see where that get's you, in both instances make sure C1E and EIST is left enabled. Hope that helps, if not report back and we'll try something else
