I tried to find more information about my processor because I am confused about if my MBP is a Santa Rosa or Peryn CPU enable computer... My Specs: Processor Name: Intel Core 2 Duo Processor Speed: 2.6 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 4 MB Bus Speed: 800 MHz I found very confusing information about my laptop because there is not clear documentation at INTEL website. My computer is supposed to be a Santa Rosa late 2007 but it was upgrade to this processor 2.6 GHz. when I go to search info about it , there is no info about any Santa Rosa CPU with this specs, only Penryn. I didn't find any accuracy documentation for my processor so far. It looks that INTEL produced 2 versions (T7800 and X7800) other websites says E6700 with same specs. Some light about how to get this information?
