Been Mac since Apple II+. Ran a graphic imaging lab at a college for 10 years. Self taught tech - some books (and iFixIt has been a great help). Currently - MacBook Pro 2.4 GHZ, Mac Pro (1st gen tower) which I upgraded to 2 X 2.66 Quad Cores w twin Samsung 23" monitors. It's a smokin' machine for Final Cut and Logic.
Answer to "Mac Pro 1.1 Change out CPU"Hey FX Your pro is now using 8 cores - WOO HOO! To the people who were all worried about power supplies and such - you are not well versed on the subject. 4-8 core upgrades have been done on Mac Pro 1.1's for a long time. If you want your processors properly recognized and some fine tuning for your fan speed, you need to look up 'Mac Pro 2.1 Firmware tool'. You can read a good thread, and probably a download, here. http://forum.netkas.org/index.php/topic,... You will need an internet connection. The package is a script that downloads and installs the appropriate files. I (and many others) have done this and all works quite well. Cheers, AJ
Answer to "Mac Pro 1.1 Change out CPU"5355's will work just fine! Head over to xlr8yourmac (dot com) for instructions and success stories. There all also good teardown videos on YouTube. You will have to do a 2.1 Firmware upgrade. No big deal. I did mine. I used 5345's 2.33 GHZ), because I got a pair for $35! I have a whole new computer. I dod video and multitrack audio - so it is badly needed. Cheers, TJ
