How to change MacPro3,1 to MacPro4,1

[zvoice]

How to change MacPro in smbios.plist? I have tried to do this using multibeast - this have caused kernel panic


UPD I have found out that this is impossible

Why are you tring to change it? Are there any specific benefits?

I've tried changing it too, using several diff utilities - Multibeast, Lizard and Chameleon Wizard but keep getting a KP each time.

Pretty sure the 4,1 and 5,1 use ECC Fully Buffered Memory, therefore you need to remove AppleTyMCEDriver.Kext to stop the Kernel Panics.
