Turbo and power saving settings for 24/7 OC

post #1 of 6
Thread Starter 
I'm running my 2500k @ 4.5 with 1.368V 24/7. I tried to do an offset but the voltage spikes under load were pretty insane. I tried different LLC's and I would get spikes up to 1.398 with even the smallest offset.

Anyway, I was wondering if it was a good idea to disable power saving and turbo features since I am running this clock 24/7.

I would.

 

If you want to try Offset again, then just use a Negative offset. I mean, if +0.005V was giving you nearly 1.4V under full load, then you need to use a negative offset.

Thing is...I was using a negative offset.

It was a real pain to find the offset because my VID nor voltage idle is constant. They both have two values.

The VID stays at 1.3561 pretty consistently. Sometimes it would jump up to 1.3611.

The idle voltage is 1.360 most of the time. It will occasionally drop to 1.352.

So, I figured I should be using the most consistent of the two values. 1.3561 and 1.360. The difference being 0.0039, therefore an offset of -.005 (rounded). I must be doing something wrong.

Here are the idle CPU voltage for the LLC at High (currently at Ultra High): 1.344-1.352

Oh. Yeah, you have to go by the idle voltage. So, go by the difference between 1.3611 and 1.344, which is -0.0171. Rounded, that's -0.015 or -0.020. Try both.

Well that's the idle voltage if I put the LLC to high. Right now I have it stable on ultra high @ 1.360v. Do recommend that I try it on high?

Why do we use the idle voltage instead of the load to find the offset?

Because vDroop needs to be considered.

 

Did you try anything lower than -0.005, like -0.010, -0.015, or -0.020? With the LLC at High or Ultra High, that should result in a much better voltage under full load.
