Can a second CPU be added to a 4core old Mac Pro?

Wondering if the 4 core MacPro4,1 machines have a single socket or dual-socket main board.

Apparently you can: http://www.everymac.com/systems/app...y-2009-nehalem-how-to-upgrade-processors.html

I upgraded my 3,1, and while it tried my patience, it was a great upgrade.

Depending on the model The 4,1 Mac Pro came either as a single or dual CPU Machine. To change a Single CPU 4,1 to a Dual CPU configuration requires new heatsinks and CPU daughter cards. For all practical purposes the answer is once a single CPU, always a single CPU system.

What you can do, however, with a 4,1 Mac Pro is upgrade the firmware to 5,1 and replace the old 4 core slow CPU with a faster 6 core model. And replace your RAM with 1333 MHz speed RAM. It will give your old machine new life.

We were lucky, 3,1's had the spare "empty" socket !
4,1's are only single OR dual socket ... no spare :-(

The cost of the new CPU tray / CPU's and heat sinks is as much or more than
the cost of a complete 4,1 mac with dual cpu's !!
