OK,i will try it tonight and share the results,Thank you!
I use air coolling systerm(NOCTUA NH-U12S),only one CPU fan.Can i test the overclock or stress?
ultra short answer: stock frequencies + enough airflow: you can use your PC :) so you can run cinebench.

now, assuming you have a powerful and reliable PSU, fresh air in your room and you're on the right fearless attitude :) if you want to verify if OC works, first:
- set a "safe" turbo freq on all cores (it could be 3.8 ghz, the intel turbo boost freq for 6800k)
- make sure your bios settings are appropriate for the context (voltages, multiplier, RAM)
- make sure all your fans are up and running at max speed
then, run cinebench on CPU to notice if it goes up to what you set.
monitor your CPU temp! it can get high, very fast. promptly stop the test if it goes over 80°C (Tcase for your i7: 127 °C).

if you want to learn something about OC, take a look here:

if you really want to experiment with OC, water cool your rig!

OC is dangerous for your rig! you must be aware you can damage it permanently! do it at your own risk.

I add PMDrvr.kext, the idle freqs is better.

Well.. don't get confused with the IDLE frequencies displayed by IPG! If you look to the core utilisation, you clearly see that the CPU load during IDLE is practically ZERO, while approaching 100% under max. load conditions.. Perfect XCPM!

I don't see any reason to further stay with PMDrvr.kext, which just breaks sleep/wake functionality and practically adds nothing really worth to be implemented! The gain is pure IPG cosmetics!

@cocoanut, I totally agree with @kgp. PMDrvr does its work, but it's unuseful here. I told you too in #2266. why don't you try #2268? I could help you with MSI bios. :thumbup:

Hi,KGP,thank your reply.The sleep/wakeup works fine when I add PMDrvr.kext. Strangely:)

I will try it:D
fine ;) and don't forget to share bios screenshots! :)
as to PMDrvr, it's good to adopt one rule: just load the essential kexts.
pay attention to the combination of idle-load / temp / power values: without PMDrvr, you were already ok.

@cocoanut see post #2010. Your sleep/wake functionality might be working fine, but is it working perfectly fine?

I think this advice..
just load the essential kexts.
is a good one. Especially if you want to avoid conflicts in future updates.

Cheers! :thumbup:

Is the provided kernel patch for XCPM on Haswell still up-to-date for 10.13.6? I can't get my XCPM to work. CPU is pegged at 3.5ghz on all cores.
sysctl machdep.xcpm.mode
machdep.xcpm.mode: 0

Maybe APpleIntelInfo output would help:
