You guys are the best! Got an answer in 5 minutes.

The Max TDP for cpus on T430 machines seem to be around 105W so no 145W 
monsters.. I guess I'll have to look for a pair of E5-2660 v4 cpus..

Also, I had one more burning question: Why is it that in the online 
documentation for the T430, the cpu sockets are symmetrical while on my 
mobo it appears that the alignment notch for both sockets is pointing in 
opposite directions? Do I have a 1st mobo?

On the above graphic, both socket orientation triangles point to the 
north-east of the chassis yet on my physical system, only socket0 does. 
socket1 points to the south-west of the chassis when looked at from the 
side.

Between stars - on stars where no human race is
I have it in me so much nearer home
To scare myself with my own desert places.       - Robert Frost
