I have a Mac Pro 2009 i'm souping up, and I flashed the 2010 firmware and all that is working, but i'm trying to reset the PRAM so that my RAM is seen as 1333 speed. Using a wireless Logitech keyboard for Mac, I've tried the COMMAND - OPTION - P - R at the bong and at the grey screen, holding it down but all it does is go to recovery. I've tried a wired USB windows keyboard and hold down WINDOWS - ALT - P - R and same thing. Each and every time it just goes to recovery. Ideas on how/when to hold and press the key combo or do I really need a wired mac keyboard?
