Can't synchronise XEON E5440

[hirion]

Hi everybody,

I put a XEON E5440 processor into a Gygabyte P43T-EX3G main board with a socket 771-775 converter. Unfortunately, I couldn't get synchronised the 4 cores of the board. 

In Boot plist the following options are: npci=0x2000, Pci Root=1, I don't use DSDT-aml.

Voodoo tscsync kext usually causes a kernel panic, in this case I can't start the system. If it does start it writes in verbose mode that the 3 cores are not synchronised. Nowadays it freezes occasionally.

Do anybody have any idea how I could make this XEON processor run?

I use OSX 10.7.5 Lion and 10.8.5 Mountain Lion.

Thanks
