Alright. Has anyone successfully upgraded his/her processors in an original MP 1,1 (2.0 GHz Xeon)? Boxed processors have finally fell to more affordable levels, and I'm considering it, to the extent that it's possible. I know I need to match the following specifications: 1333 FSB LGA 771 I'm looking at Quad core chips. My current processors (I think) look to be Xeon 5130s, running at 65W. Do I need to add any additional heat sink/cooling measures for 80W processors? Will they even work? Any knowledgeable advice would be appreciated!
