    I have a 4,1 dual CPU model I have had for few years and have successfully repaired the tray due to a Northbridge heatsink failure.

    I feel a little more confident now.
    What is the fastest set of processors (quad cores) I can install in this unit without any modifications?
    I am not looking into flashing firmware into 5,1 or delidding at this time. I am looking for a simple swap.

    I see X5570 2.93 for about $65.

    A pair of W5590 processors would get you 8 cores @ 3.33 GHz. There's a seller on eBay offering delidded versions of these. (Not a recommendation.)

    I encourage you to reconsider flashing the firmware, though. It's very simple. Then look at a pair of X5677, X5680, or X5690, and have them delidded.

    Just to clarify the differences (from TomsHardware):

    X = TDP of 95 watts. These are the "premium" mainstream chips as their TDP is not so excessive that they are difficult to cool in a rack server, yet their idle power consumption is far lower than the E-series chips.

    W = TDP of 130 watts and higher. These are the fastest, hottest Xeons made and they are designed to be used in workstations and pedestal servers with better cooling than an average 1U or 2U rack server.

    Not really, the W and X is not related to their TDP in this generation. Both W3690 and X5690 are 130W TDP.

    Actually that is incorrect as of X56XX series of CPUs (it was correct back with the X55XX). As Mr. Numbers pointed out above things have changed. I posted the correct info below 13 months ago:

    To the OP. I second what Scott posted above. Why are you hesitant about updating the firmware to a 5,1? That is far easier than a CPU swap. I recommend you update your firmware and get a later series X56XX CPU rather than the W55XX series. I have a real 5,1 and have updated my CPUs twice first to the W5590s than to the X5677s. I can tell you that as well as a speed increase I also got a small reduction in power draw and the X5677s run a bit cooler than the W5590s did.

    Flowrider and haralds are correct. But I don't think the OP needs to worry TDP-wise about running the W5590 processors; lots of us are happily running dual 130 TDP (mostly X5600 series) processors in our 2009 Mac Pros.

    I'm not looking to spend a bundle, and somehow I have a feeling Appl will come up with a way to run the OS only on known hardware (serial numbers) matched to firmware etc. just a feeling I have if their next step of "protecting the security of OS" sort of how some things don't run properly in a VM such as Caching Service.

    Strictly dual quads is the x5570 the fastest?

    ^^^^No, as I said above for the CPUs that work on the 4,1 Mac Pro, the W5590 (3.33MHz) is the fastest chip available.

    I see.
    Is there something "in between" x5570 and w5590

    Better yet is there a write up that shows all the possible processors for the dual quad

    I doubt it. I think almost every 4,1 user in these forums has done the 5,1 firmware update. I guess we could all be screwed together. Wouldn't be the first time... or the last :(

    Look Here:

    http://cpuboss.com/cpus/Intel-Xeon-X5570-vs-Intel-Xeon-W5590

    http://cpuboss.com/cpus/Intel-Xeon-W5580-vs-Intel-Xeon-W5590

    And here's a matched pair of W5590s for less than $100.00.

    And see attachment for all 55XX series CPUs - All will work in a Dual (or single) CPU 4,1 or 5,1 Mac Pro.

    Wait forgive me Lou but I thought you said the Xeon X5677's are faster and cooler. Will they not run in a Mac Pro 4,1?

    Also I've been reading through a ton of threads over the past few days and I've read a lot of your post. Thanks a million for all of your contributions to the forum.

    Thanks!

    The X5677 requires the 5,1 firmware upgrade.

    Yes, I did, and it's true, but as scott said above, the X5677s require 5,1 firmware.

    Thanks for the reply guys, I missed the part about not wanting to do the firmware upgrade. I recently ordered a 4,1 Mac and I'm trying to figure out what CPU's to buy. The X5677's seem great especially for their price and high speed per core. On the other hand I really only want to do this processor swap one time so maybe I should just go with the X5690's knowing that this is as good as it gets. Any thoughts?

    Thanks!

    Has Apple ever done anything like tying down an OS to specific combinations of serial numbers and firmware? That's going really much further than I think they'd go. Also such a move would probably disrupt those who have had authorized service and may have received a newer replacement board due to hardware failure. I cannot imagine Apple doing this, and I certainly wouldn't restrict my CPU choices based on that fear.

    Not to mention that the combination of the firmware update and faster Westmere CPUs also enables the use of faster 1333 RAM instead of 1066.
