    • added the backplane board

    I believe the image in step 3 is the graphics card and not the backplane.

    • Bluetooth antenna connected to the card on the Backplane board. One needs to be careful because if not connected the Antenna needs to be attached in order not to short-circuit the backpanel board.

I have Mac Pro 5,1 intel Xeon W3565 at 3.2 GHz Quad-Core.

It is easy to upgrade in W3565 at 3.33 GHz 6-Core ???

Any intel Xeon W3565 fit in my Mac Pro ?

What CPU sockets supported for ?

Thank you,

It is socket-b(LGA 1366)

I think it is easy to upgrade your CPU

It should be easy to upgrade a single-cpu Pro, they use standard lidded Xeons. I am planning on upgrading to W3690s in a couple of 4,1 machines that have had their firmware flashed to 5,1.

Please let me know how you handle that upgrade!! Or add a tutorial id vey much like to see that and maybe follow suit but im not very savy with these upgrades

Is it possible to easily remove and service right processor fan (the back one)? It makes too much noise, so needs some oil apparently. I didn't find any way to remove it.

I replaced sockets in motherboard 820-2336-А and lose two resistors R5400 and R3613.Prompt please resistors face values.Thanks!

Is it possible to replace the fans with quieter fans?

I have acquired a MacPro 4,1 from my friend who no longer needed it and couldn't get it working anyway. The weirdest thing is none of the internal drives show up, not even when booting off an external OS drive, and the ethernet ports as well. Everything else seems to work, installed a fresh copy of El Capitan on an external and all works but these two items. Makes me believe that there may be a disconnected or bad cable to the backplane but I am having a hard time finding the info online and any pictures on what to look for. Any ideas or suggestions?

Hello barrebbi, I just had the same problem happen to me the macpro was working well and all of the sudden the drives disappear and the internet connection was gonne too . I try to unplug everything and do a pram clean and nothing, the next thing I will do is run the ahd diagnose utility for this computer. what I am missing is the internal drivers the 4 internal sata’s but the optical drives are working fine, also I lost the wifi, ethernet and the optical audio port. the external audio is fine. I was browsing online nothing really taxing for the computer. if I cannot fix it I will install a pci usb 3 port to run external drives and a usb3 to ethernet port to get the network and internet back and a usb bluetooth dongle. If anyone can help or guide us to find a solution I will great appreciated. Berrebbi if you find anything please advice I will do so too. Thanks in advance.

Sorry, I have not been able to get an answer yet. And for some reason, this model won’t upgrade bootcamp to Windows 10 (or 8) either, black screen. I’ve updated older models but not this one.

Missing connection of HDD bays and, more importantly, the connections between the HDD bays and the logic board.

Still haven’t figured it out yet

I’m lost as to why this is titled as a “Teardown” when it is in fact an “Assembly”…

Is the Bluetooth connector on the motherboard a standard USB single port [Vcc, D-, D+, GND] connector ?

dan.streaman - Reply

Nope, there’s a picture in step 10- I think it’s a PCI-E connector of some type. Definitely not USB though.
