i5-8265U incorrect power management #9
Description
I don't know what causes this issue, but no matter how I try to set power management for my machine, it looks like at least one core is staying at least at base frequency (1.8GHz). This leads to power consumption, fast battery drain and heating up.
Also, my CPU's LFM is at 400Mhz, yet it seems as if it never goes below 700Mhz, even when idle. With SSDT it even gets weirder, as for some reason it does not let the frequency get below 1.1GHz.
I tried different configurations, with different values, but each and everyone of them resulted in the exact same performance, and same problems...
I have a Dell Vostro 14 5481, and using opencore 0.6.3 (tried with all versions since 0.5.9, including a couple of clover versions), tried with both SSDT and Kext. SMBios is MacBookPro16,3 (tried with MacBookPro15,2 as well).
Edit: to be clear, the main issues are:
- Not being able to get to actual LFM.
- One core (or thread?) Won't go below base frequency.
- Overall bad battery usage time, no-so-great performance, and CPU temp staying relatively high even when idle. This might be solved by fixing the previous ones.
