Welcome to the main BIOS screen of this motherboard, freshly updated to latest v4.9 firmware.

Since I need to keep a record of this for my own reference, too, here is the visual guide of minimal BIOS settings to run OS X via Chameleon or Clover. VISUAL GUIDE TO “MSI Z97i-AC” BIOS SETTINGS Finally, check that “C1E Support” is enabled (check with your CPU specifications).Īfter this handful of changes, go to the main screen and opt to “Save And Reboot” the computer.Check that “Intel C-State” is enabled (check with your CPU specifications).Set to “IGD” as the graphics adapter to initialize (if only using HD Graphics).Disable “Full Screen Logo” option (there’s a good reason for it, I will explain).Disable “Serial (COM) Port” completely (not really needed, but it’s just me).Enable “Extreme Memory Profile (XMP)” to boost performance.Disable “CFG Lock” completely (very critical, won’t boot either).Disable “Intel VT-d Technology” completely (otherwise, OS X won’t boot).Update to the latest available BIOS from manufacturer!.With some parallel research on my favourite forums, the seemingly typical BIOS settings are really minimal, summarized below: The cooling is performed by a Skythe Ashura, for really silent computing (and some over-clocking, too).Īfter assembly, I booted the computer and went straight to the BIOS update menu, flashed it with latest v4.9 firmware (as found on MSI’s own website). No dedicated graphics card, since I planned to use the embedded Intel HD Graphics 4600 of the CPU (more like a Mac Mini). Additionally, I used again my 2 Corsair Vengeance (Low Profile) memory modules (1600MHz CL9), totalling 16GB of dual-channel RAM (they support Intel XMP v1.3, too). I installed the Intel Core i7-4790K processor (4.0 GHz), hence still in need of a Z97 chipset that can support such unlocked CPU. Please note, it’s not the “Gaming” variant, which costs more (for some reason). The price point and budget allowed me to choose between an ASUS and MSI branded mATX motherboard, so I went for the MSI Z97i-AC board, as it was offering DisplayPort that I really want to check out. Following my failed attempt to setup a stable haxie with my previously purchased Gigabyte GA-Z87N-WIFI motherboard and my fast Haswell CPU, despite other users not having any reported issues (per my search results on the net), I decided to ditch it and go for something different.
