After a few days of testing the Dual CPU Hackintosh is complete. So lets talk about the system! I am not a professional reviewer but here we go.
2 x XEON E5-2670 8 CORE @2.60GHz
CORSAIR Hydro Series H60
CORSAIR 850 WATT PSU
WD 1TB Sata III HDD
GTX 780 (From Main System)
64GB (8GBx8) DDR3 Ram (From Main System)
4GB (2GBx2) DDR3 RAM (When using Main System)
Generic Rack Mount Case
First I was able to achieve everything that I wanted to do. Creating a stable platform for users to use the system as a editing/production system. Obtain a Geek Bench Score over 35000. Use the latest version of Mac OS X.
A good friend of mine worked with me on editing a AICPM.Kext to enable Power Management for the CPUs. Assuming that if I had used v2 CPUS I would not have had to do with. I then discovered that this board has a locked MSR so I used Clover to address this issue. A few more Clover tweaks and I was able to boot without NullCPU installed.
Some of the challenges that I faced was enabling Onboard LAN. The Dual Intel i350 Ethernet ports are based on the Intel i210 Ethernet Chipset. Knowing this I used are Ethernet guide found here to obtain the supported Device ID for the i210 and injected the Device ID for both ports in the SSDT for the board. I then moved to Onboard Audio which is ALC889. A simple edit to the SSDT and I was able to enable and then patch Onboard Audio. We only tested Green Output on the back of the board which worked and assume the rest of the ports work.
Obtaining a stable Geekbench and Cinebench score. In the end I discovered by using MacPro 6,1 SMBIOS was not stable for the system. Something running in the background was causing my system to be held back. Switching to iMac 14,2 resolved my issues with the CPU and a quick AGPM.Kext edit allowed me to obtain a solid Cinebench score.
The hardest challenge was creating a SSDT-1 for Power Management. This proved very difficult as simple changes to the file would either make the system not boot or drop 10000 points in Geek bench. For someone considering this build with different CPUS we strongly recommend that you contact us prior to building the system.
I then spent several hours trying to brake the installation I identified some open issues and was able to easily correct them. Last I was not able to enable the USB 3.0 ports to detect USB 3.0 devices. The ports do work however with USB 2.0 devices. The ports are NEC based and have a known issue under Mac OS X 10.11.
With dual XEON E5-2670 cpus I was able to achieve a final Geek Bench score of 35051 which can be viewed here. A score over 35000 was my original goal. under Windows I have only been able to achieve a final Geek Bench score of 33000.
I you would like to know more about the system ask below in the comments! A DMG for this board is in the works but we would like to try to bridging the gap to cover the cost of the system. We still need your help!
