OWC CPU Upgrade for 2010/2012 Mac Pro
Lately a number of inquiries have been received about MPG Pro Workstation builds, but some are really about CPU upgrades.
To upgrade the CPU in the 2010/2012 Mac Pro is a simple and fast processor tray swap—no tools required and the tray is trivially easy to remove/replace. OWC does the work of actually swapping the CPUs on the tray. Consider additional memory at the same time.
