    Good, cheap MacPro 1,1 upgrade

    The X5355 is only about 7% slower than the X5365 used in the MacPro 2,1 and can be found at a much lower cost. The installation can be harder than online guides suggest if your MacPro's parts have stuck together with age, but if you disassemble it in the right order it can be done. Be sure you upgrade the firmware before installing and reset the PRAM (cmd-opt-P-R) after the chips are in. Macs Fan Control will tame the runaway fans (try out the options). The oldest MacPro can still be a reliable, expandable, powerful machine!

    easy to install, quick way to improve an older Mac

    bought these to upgrade my Mac Pro 1,1 and made it a Mac Pro 2,1. went form a Quad core Mac Pro to an 8-core Mac Pro. installation was so easy. watched videos on how to do the swap, and it was so much easier than i had ever thought. the quad core Xeon chips work well, as they should. Getting these as used was a lot less expensive as if they were brand new. save much money and turned out to be a great value being a used product, but knowing that they were tested and were working when removed from where they came from.

    Just what I ordered!

    Just the upgrade I needed for a MacPro 1,1. Installation went smoothly and resulted in new machine. Highly recommend this upgrade. CPUs arrived promptly and I was up and running with a new MacPro.

    Cheap upgrade that works well.

    Have been running these on an early mac pro tower for a couple of years now with no problems. Cheap way to extend the life of an early machine.
