Unlock Max turbo for Haswell Xeon cpu?

[mimixa]

On the Mac OS x this is normal (Mac os x itself adjusts the power depending on the power consumption) .

You check in Windows there will be higher. You can still increase it but it is too dangerous and will not work stably.

I'm quite happy with EFI-90-50 . I have not tried OpenCore yet .

I don’t use it now, because I don’t know how to do it correctly in Open Core.
From experience with use, I can assure you that the frequency readings in
Mac OS X and Windows differ 2900 and 3300. I believe that this is due to the fact that the Mac itself limits the frequencies according to the selected configuration.
I did not use it myself, but some spoke well about the EFI with increased voltage.

U need to put an .efi file in your clover bootloader I only have it for E5 2996V3 but you can look here https://forums.anandtech.com/threads/what-controls-turbo-core-in-xeons.2496647/ to get some turbo efi files for your cpu

And what about ssdt e.t.c ot it can work without it just with efi drivers?

For turbo theres no need for any specific ssdt ...

Dj_adam21,

I found de V3.EFI and put into the clover bootloader, and for once It unlocked the 3.2GHz (Xeon V3 2620) turbo for my Hackintosh (Catalina Version) but as soon as I rebooted I couldn't get the unlock boost anymore. Now, on the bios its appearing this message: "V3 overclocking locked".

I also tried with no success reseted all clover configuration, reset bios configuration, remove Motherboard battery. The Overclocking on windows still working.

Do You have any clue?

Thanks!

Never happened to me , make sure the file is in CLOVER-DRIVERS-UEFI folder, if not maybe try to flash the bios again.
Hope it helps
