Z600 cpu upgrade with x5679

Hi all folks,

I'm thinkingto make an upgrade to my z600 hp which is the version 1 wokstation. So I want to buy a rev. 2 motherboard , and to put on it 2 cpu's - x5679 having:

Clockspeed: 3.2 GHz
Turbo Speed: 3.6 GHz
No of Cores: 6 (2 logical cores per physical)
Typical TDP: 115 W

and to add 48 gb of ram ecc registered. 

My question and wondering is, have and idea or clue if,  it is posibile to work x5679 cpu on rev .2 (C2) motherboard, that in the hp support say that cpu x5675, (TDP 95 w), is the maxim cpu. 

Thanks, best regards!
