Hi there, I managed to get my P55-UD5 running ok. Try downloading the DSDT for your board from this site, helped me a lot with getting Mavericks to play nice. My own DSDT that I've been using since 10.5 did not work well with mavericks!
If you're already running hackintosh then use your current smbios and have a care about the kexts that you may need.
