I have a very specific question about upgrading a 2009 Mac Pro from a single CPU to a dual CPU.
I want to do this upgrade a little bit at a time, since the parts are kind of expensive. My single processor is a 6-core 3.33. If I start by replacing my processor tray with a dual tray, can I run the dual tray with only one CPU installed? For as long as it takes me to find/save up for the smaller dual heat sinks and a second matching 6-core CPU?
