Hey all,

I built my hackintosh and got everything running fine on el capitan.
I used this guide, as the board and components were similar:

However, the motherboard is giving error code 51 when it enters the OS.

On boot, it cycles through the normal checks, then sits on 99. When the loader goes to OSX, it shows 61 for a few seconds, then 51.

I reseated the ram and cpu, tried 1 stick, then 2 and believe it returned a different RAM code error (55).
Then 4 again. Same error (51).
I called and checked gigabyte's forums. Some say this could be caused by bios settings.
I'm currently using ver. F5 and considering F6F beta bios flash, as it may have better RAM compatibility.

I checked with windows, same code occurs. I boot directly to OSX without the loader, same error.

The system settings shows that 64gb are installed, at 2400 speed. I'm concerned it may only be running at 2133.
When I try to adjust speed settings to OC the CPU, the OS won't load until i change to default.

If anyone has advice on either this RAM error or a quick fix for the CPU OC, please let me know.
