Inside the EfiUpdaterApp2.efi program are a list of firmware version strings from different releases of the 2010 Mac Pro, along with the CRC32 checksum of the firmware image file. So how do we get the program to load the other firmware? It turns out that it is surprisingly easy. This boot file is then blessed in a special way, and the next time the Mac is booted from shutdown, with the power button held down for a few seconds, this special EFI program is run. The firmware updater package, after checking that the Mac can use the update, places an EFI boot file named EFIUpdaterApp2.efi, which is very similar in structure to the standard boot file that starts a Mac on the system volume, in the /System/Library/Core Services/Firmware Updates folder, along with the actual firmware image.

To explain how this was accomplished, let me first describe how the firmware update process works on a Mac. As long as the SMC firmware version matches between the main board and the CPU board, everything works perfectly. The CPU socket issue is transparent to the firmware, and the SMC firmware difference between 20 models is not an issue. The only thing that differs is the CPU socket mechanism on the dual CPU model, which uses Xeon CPUs with the IHS (Integrated Heat Spreader) removed, and the SMC firmware version. The hardware of these models is very close.

I decided to see if it was possible to come up with a way to update the firmware on the 2009 Mac Pro with the firmware from the 2010 Mac Pro. Such is the case with the 2007 Mac Pro (MacPro2,1) and the 2010 Mac Pro (MacPro5,1). « Last Edit: January 31, 2015, 04:22:17 PM by James Lemon 007 »Īs you may know, some Mac Pro models have been introduced that are identical or very nearly identical to the model that preceded them. I didn't have that special 2009 refurbished EFI on it, I checked that first. I took out the Sonnet SSD Card and replaced the graphics card with the AppleGT120 for flashing. Not sure if you meant the mounting of the FW image. One the disadvantage is that it runs hotter, at least the IOH heat sink of the IOH Tdiode is much hotter than before. Thats the reason why I try to down grade. If you have a SSD PCIE card from Sonett, there is a disadvantage, When I spooled on the 5.1, I had to do that also.īut now even with mounted dmg that did work. I did read the posts and mounted the 2009 FW image. Yes makes sense, that it is the 2 hexa v.s. If you got this Error message (5570), please read some posts before.Īnd you dont have any disadvantage upgrading to the 5.1. I upgraded from 2 x Quad to 2 x Hexa (2,93 Ghz) and then the RAM was switched to 1333 Mhz. I guess this has to do with the Quad Core Prozessor. Other wise I`ll get a couple of Xeons and upgrade.īut im worried that the Ram still stays 1066. So I do unterstand its risky, just hoping some one had the same problem. I build several Hackintoshes from the first one, the Core 2 Duo. Now I cant downgrade any more, 5570 error, downloading and mounting the 2009 EFI.dmg didn't help either. Since it does not work, I wanted to go back, because I use a SSD PCI card and with 5.1 we can't choose the startup disk from cold boot. I read that the original 2 processor 8 core X5550 2.66 is capable of running 1333 ram. Its the Ram for the 2010 Mac Pro.Īny one tried this with the X5550 successfully ? The Ram is 3x8GB OWC 1333, in Slot 1, 2 and 3. « Last Edit: January 25, 2015, 08:21:54 AM by Condeavor1 »īut, even after several times PRAM and SMC reset, it sticks 1066. According to Intel, these processors fully support 1333Mhz RAM. so I may not be interpreting that right, so correct me if im wrong in saying thw 1333Mhz is active?ĮDIT3: I have now installed Lion on a secondary SSD and I do see under Hardware it listing (as it did in Yosemite) as a 5,1- but should it still show 2009 Mac Pro on the About this Mac page? Also, no change in RAM.
#Mac pro 5.1 cpu upgrade windows 10#
I'm still trying to fin the exact clocking of the RAM (been a while since I went that in-depth while in Windows, and it's Windows 10 Beta, so.), but Geekbench reported single stream processes at 1334.
dammitĮDIT2: OK, so after entering Windows it shows my EFI as 5,1 so it's there obviously. If anyone has had similar issues, i would appreciate.ĮDIT1: I now see it's limited to Lion.
#Mac pro 5.1 cpu upgrade full#
I'm have yet to see if Windows is seeing the full RAM speed, but am not confident. I've cleared the PRAM, but cannot think of why it may not be functioning. The app is reporting 2010 EFI is installed in Yosemite, but my system report is not reflecting it.
