Core2Extreme QX6850 and OS X Mavericks

I have my Hackintosh more or less working, but it's behaving a bit oddly graphically. There's a lag, and it won't refresh correctly, and I just noticed that if I let the screensaver activate, the whole machine will crash and auto reboot.

 

It happened after I installed a Core2Extreme QX6850, which is seen in About This Mac... as a Quad Core Xeon. Before the upgrade I had a Core2Duo E8400, and it worked perfectly.

 

I have good drivers for my graphics card (ATI Radeon HD 4650), and the card worked fine under OS X before the CPU upgrade, and continues to work fine under Windows, so I doubt this is the issue.

 

Is it possible that mach_kernel (which, to my knowledge, determines which CPUs OS X is compatible with) is misconfiguring the CPU somehow because it isn't 100% compatible with it? Or maybe a DSDT issue? Someone in another thread suggested spoofing the CPU ID. Would that help? How, exactly, do I do it?

 

I want to try to keep Mavericks if I can, as I prefer its GUI, but if it simply isn't compatible with the QX6850, and there's no way to fix it, then I'll bite the bullet and upgrade.

 

Any help would be appreciated!

OK, but what would the IOCPU number be for a C2E? Would it be the same as a Core2Quad? How do I find out? Sorry about all the "newbie" like questions!! :)

 

EDIT: I think I figured it out. It represents the number of cores. Yes?
