Dual Cpu Tray For Mac
The fans on my 2009 Mac Pro are running at full speed after upgrading the CPU tray to the tray from a 2012 12 core. Temperature monitor reports that the CPU temperatures are steady 32° and 34°c, and all other temperatures are within that range, and other than the howling noise my Mac Pro is running perfectly normally. The firmware has been upgraded as per this site and the OS is Sierra. I've currently dropped back to the factory fitted 2.66GHz quad, albeit with the same firmware, and all is quiet and peaceful again. I can't run AHT or diagnostics because neither are installed on the machine - and I don't know what I've done with the installer disk.
I have reset the SMC and NVRAM to be sure it's not a simple software / configuration fix. Can anyone suggest a fix? I'm at a loss because the temperatures report as being entirely healthy! Changing the entire tray could lead to problems. When you upgraded the tray, which firmware did you upgrade, the Boot Rom version or the SMC version? You need to upgrade both for this upgrade to work. The new boot rom version should be: MP51.007F.B03.
The new SMC firmware should be 1.39f11. If you go to About this Mac - System Report - Hardware Overview, you'll be able to see this information. For example, my Mac Pro 4,1 (5,1 firmware) has boot rom version 51.007F.B03. However, because my tray is still the original tray, my SMC Version is 1.39f5. – Dec 20 '16 at 2:00. Copied directly from Apple Discussions: I can claim nothing but Google-Fu on this one. My SMC is the same as NoahL's 1.39f5 so I can only presume mine has the original 4,1 daughterboard, with 3.46GHz Westmeres added after-market.
I bought mine ready-upgraded, so it's not a process I've ever done myself. From this, though, it would appear that the 2 versions of the CPU/RAM daughterboard are not interchangeable. I think I can answer the question now. There was a misunderstanding regarding the firmware upgrade tool to upgrade a Mac Pro 4,1 to 5,1.
The firmware upgarde tool does not update the SMC firmware, but installs a different boot rom version. Mac Pro 4,1 (2009): MP41.0081.B07 (original) Mac Pro 5,1 (2009): MP51.007F.B03 (upgraded) The system and CPU board SMC version remains at 1.39f5 for the MacPro 2009. A Mac Pro 2010 uses 1.39f11. Ftp for mac osx.
After upgrading a Mac Pro 4,1 to 5,1, the SMC firmware was still 1.39f5. SMC mainly deals with temperatures and fan speeds. It is important that the SMC version of the CPU and system are the same.
So to answer my question, it is not possible to use a 5,1 CPU board in a 4,1 system or vice versa. I'm not sure what happens when mixing them, but apparently the system does either not boot or the fans go crazy, perhaps depending whether you put a 5,1 cpu board into a 4,1 system or vice versa. Here are some links I found meanwhile for reference: Btw, the firmware upgrade tool 4,1 to 5,1 shows error 5570. That is because Apple changed the location of the 5,1 efi firmware image. You can however download the 5,1 firmware from Apple and simply mount the disk image prior to running the tool and it will work fine.
Then shutdown the system and hold down the power button until a tone occurs, then the system will restart and show a progress bar to update the firmware.
I've got a problem. I have a mid-2010 MacPro 5,1 (Boot Rom version: MP51.007F.B03). Initially, I had a single processor tray with a 2.8 GHz quad-core Xeon processor. I upgraded it to the X5690 six core 3.46 GHz processor.
No problems- smooth transition. Incidentally- RAM = 4 x 8 GB went from 1066 MHz to 1333 MHz. Then I saw a dual processor tray with 2 x 2.26 GHz on eBay and figured I'd upgrade from a single processor to a dual processor, and would replace the 2 x 2.6 GHz to 2 x 3.46 GHz- from 8 core to 12 core (which I haven't done yet).
The problem is that the dual processor tray was from a 2009 MacPro 4,1 with 2 x 2.26 GHz. When I replaced my single processor tray with the dual processor tray, all of the fans except BoostA stopped working. The BoostA fan was blowing at about 1600-1700 RPM (about two times the normal rate) and it was LOUD. The temps seemed ok for everything, but I wasn't doing anything and the computer was only on for about 10 minutes.
In 'About This Mac', the EFI was still 5,1 with the dual processor tray from the 4,1. I figured I would reinstall my old 2.8 GHz processor (which I did) and then try to downgrade to the 2009 4,1 EFI so I could put the dual processor tray in and upgrade everything (back) to 5,1. I got an error every time. Is there anything I can do to get the dual processor tray to work seamlessly with all fans working correctly (and quietly) under my 5,1 EFI?
Do I need to flash the tray on another Mac (if so, I don't know where I'd find another 4,1)? I'm desperate to get this configuration to work. Any help would be greatly appreciated!! Apple Footer.
