Ahnafakeef,
TD and I have two differnet mobos, so that might be causing some confustion. On the MVF the CPU_FAN and CPU_OPT headers are designed to work together and are controlled as one unit in bios. I have not heard anyone having trouble with them on the MVF.

Are your fand 4 pin pwm, or are they 3 pin? What about the stock cooler fans, are they 3 or 4 pin? Fan(s) used with a cpu cooler are normally 4 pin pwm.

Rss013,
I think I just posted this recently, but switch to balanced power plan and see if that takes you down to 1600 while idle. Offset is up to you at those relatively low settings, but I would try both offset and manual and then you will be able to see the voltage and temp difference at idle for yourself, then make a decision.

VID under load is the only one that matters but you are not downclocking at idle as you posted that is part of the VID confusion. PLL has nothing to do with it, it is most likely your power setting.

You say your VID while idling is lower than when under load but:

VID @ Idle : 1.2460~1.2510
VID @ Load : 1.2260~1.2310

doesnt represent that. So which is it actually? tongue.gif

Also with such a low voltage needed you probably cant use offset anyways because if your real VID is the 1.2510 then your offset would be something like - 0.071V at which point your idle voltage would be something close to 0.87V and could probably cause instability while idling. I had that problem myself.

Good point, forgot to mention that.
When you use a negative offset, you can end up with too low a voltage at idle. Every chip is different so the only way to know is test it. Personally I would go up to 4.6 so as not to worry about that, but that is just me.

Oke you mean the setting in windows @ Energy Management right? It is now set at "High Performance" as i didn't noticed sry.
So if i take my : VID under load : (1.226) - vcore bios (1.180) =( 0,046) <=== this is my "NEGATIVE-" offset then right?
Sry i ask so much in a short period, but there is just coming alot of information to me atm since i'm new to this rolleyes.gif
Thanks alot again smile.gif

Sry i had to be more specific :

For the load it is most frequently @ 1.2260
For idle it is @ 1.2460 checked with CoreTemp

I will stick to fixed then if offset may cause stabilty problems, thnx smile.gif

If you want High Performance as your power plan, then go into the advanced power options settings and change Processor Power Management > Minimum processor state Setting from 100% to 5%. Or just switch from High Performance to Balanced in the power plan window.

If 1.2260 is your most common VID under load at 4.5, then yes you would choose a negative offset then type in .045 (since it is in increments of .005 you can’t use .046). As Chunin pointed out, you will have to test these offset settings to see if they keep you stable. With a negative offset you may have idle instabilities, but you just have to test it and see.

4.6 would put you at a manual 1.24v or so I think which is above your VID and you wouldn’t have to worry about having a negative offset, which is why I mentioned that.

I posted awhile back that this thread is different than some others here. Ask as many questions as you want, as many times as you want until you feel comfortable.

Things are slowly seem to get clear for me now.
I think i have to be glad with my current OC atm with these temps and volts, and also to check further stability the coming weeks..
I always can try out some other stuff later if im not happy with my currrent clock.
Anyway, everything i have reached so far, wasn't possible without the help of you guys, +rep for all of you who helped me out thanks smile.gif

he mentioned he running Corsair SP120 performance fans (2200rpm).3 wire . .

I'm partly curious as to how I am supposed to test for stability at a certain frequency, when the CPU throttles due to hitting the maximum temperatures?

If that is happening you need to get better HS or find out why its so high .

What core temps are you getting ?
