Hello everyone, Last year I picked up a 2008 Mac Pro with the 1 x 2.8 GHz quad core CPU. The guy who sold it to me recently mentioned the possibility of upgrading the CPU, which I decided to do with a Xeon X5482 (SLANZ). When I got that CPU cover out of the Mac Pro case, I realized that this computer has a second, empty CPU socket just waiting to be filled. So my plan now is to order a second CPU and heat sink to take this from 1 x 2.8 GHz to 2 x 3.2 GHz for a total of 8 cores. Has anyone done this before? Is there anything else I'd need to do beyond physically installing the second CPU to make it work, like a firmware update or something? I appreciate any advice.
