[OC]Keep getting this error, screen goes black after timeout

My Specs:

• Motherboard Intel IG45ID
• GPU XFX Nvidia 9600GT 512MB
• CPU Intel Core 2 Quad Q8300
• OpenCore 0.6.8
• MacOS Installer Ver: High Sierra 10.13.6

My EFI folder: download

Note: although my motherboard has a UEFI mode, the only way I've gotten OC to work has been through Legacy BIOS mode.

Thanks in advance
