Guide to Installing Mountain Lion on HP Probook

As you can notice, there are different IP-addresses of apple time server. Maybe you should specify it manually

Actually, there are instances where the same server was used several times in a row. But the drift still varies, sometimes by significant amounts.
 
That's your log:

The only curious thing is the red line. And all of the rest shows that offset slightly increases. But it is too insignificant and it means, that your bus speed value is correct. I had much significant offsets with BusSpeed, that Clover detected automaticaly. And I suppose it affected audio syncronization in Logic.
 
My point was that the amount of drift is not very consistent, even from the same server.

In my view this section was more interesting...

Min=-0.007885
Max=-0.031657

They are different by a factor of ~4.015 (0.031657/0.007885).

I think it means that the method is an inaccurate way of measuring or some sort of average between differences should be employed. Because individual drifts measurements in one hour of time can be significantly different.
 
So you tell me how to detect this value in accurate way. I've found the reason of audio cracking and solution. May be there is any other way to do it. Should I remove my manual value, then switch UEFI to legacy mode and check this value in log-file of Clover ? I've read that Clover detects an inaccurate value when it boots UEFI native
 
I had Mountain Lion running on a Probook 4730s. Unfortunately the CPU had to be replaced and was upgraded from i3 to i7. I now get a kernel panic when booting with P-State error 18. Is there a possibility to make it boot again?

Boot using USB. Create new SSDT and re-patch DSDT.

Just "-f"? Or do I need more bootflags?

-f will ignore kernel cache, which is likely your problem. Other than that, I have no ability to predict the future.
