Hi there.
Can i upgrade my Mac pro 2.66 with processor X5670 2.93 or 3.46 X5690

I understand that it will break warranty, but i'm ready 🙄

yes there is a hack and it will let your 8 core 2009 take a pair of hex 3.46's to become a dual hex. but this should be in mac pro not iMac. There is a Mac pro thread on this.

How many cores do you have now? If you've already got 12, I'd say that would be a waste, but wouldn't be too hard.

from wiki:

2009 mac pros have;


One 2.66 GHz (W3520) Quad-Core Intel Xeon "Bloomfield" or two 2.26 GHz (E5520) Quad-core Intel Xeon "Gainstown" with 8 MB of L3 cache
Optional 2.93 GHz (W3540) or 3.33 GHz (W3580) Intel Xeon Quad-core Intel Xeon "Bloomfield" processors or two 2.66 GHz (X5550) or 2.93 GHz (X5570) Quad-core Intel Xeon "Gainstown" processors




so if you have a two 2.66GHz x5550 2009 macpro it can be turned into a x5690 dual hex machine.. it is costly and not easy.

you need an efi hack and you need to not crush the cpu sockets. here is a link on the crushed sockets

read this he killed his machine!
