    Troubles with proper turbo boost frequency

    Hey, So I recently noticed that my i7 4790 (Not K) Isn't getting to a turbo boost frequency of 4.0Ghz but rather topping out at 3.8Ghz Is there a solution to this? I assume it has something to do with the iMac 14,2 SMBIOS I am using and the slightly different CPU choice from a 4790K which...

    Error loading kernel cache 0xe

    Hi all. I used my first hackintosh installation without any problem for 6 month. But today, I can’t boot Sierra 12.3 anymore. I’m using NullCPUPM with IMac14,2. CPU’s heat is reduced but multiplier doesn’t change and VCore always stays around 1.672V(wrong value it should be 0.85-1.35). I did try...

    Mini-ITX + ECC... Success?

    Hello Everyone! I've been trying to install Sierra on an ASRock E3C224D2I + G1820 + 4GB ECC RAM, and it's working... apparently. My idea was to transform an old nas4free server into something a bit more versatile than just a file server (VPN, etc.), so I decided to install MacOS+OpenZFS into it...
