Hi guys, first of sorry to wake this old thread, I'm trying really hard to get my SR 2 to work with my dual GPU GTX 480.
Right now I'm stock in a step that i know the next one is to show OSX GUI when booting to use OS X, and that every single thread that i found related to this boot problem, points to the GPU.
Here is are my hw specs
2 x EVGA GTX 480
2 x Westmere 5620 @ 2.40GHz (no overclocking)
24 GB RAM ECC Reg Tri channel
1 x OCZ 120gb SATA III
1x 2TB Seagate SATA III
Installed using iAtkos L2
Selected IOPCIFamily, Disabler, CPU Throtler, FakeSMC, Graphics Enabler, GT100 for GTX fermi support, Chameleon 2.1, AHCI SATA, SSD TRIM
First i ran the installation with one CPU and one GPU, then when i booted completly i added the second CPU, and the rest of the RAM, everything went normal, i got to the osx gui, all cores and ram is recognized and I'm able to perform anything that i want, but when i add the second GPU the boot process stucks at "DSMOS has arrived".
I tried PCIRootUID=1, but when i get to the gui the resolution is stuck at 1280x1024, i tried also npci=0x2000 and npci=0x3000 and gives the same result. Also did a new fresh installation using ATY_init and with that kext i got into osx with the corresponding resolution, but the weird thing is that when i turn on the computer the dvi cable is connected to the primary gpu card, but when the osx gui appears, i have to switch the cable to the secondary GPU and when i open the System Information, both card shows up, but the secondary GPU reports only 512mb of vram instead of 1534MB. As a side note, the Mac Pro version appears as 3,1, i changed it with ###### to MacPro 5,1 but the problem still persist.
Is there something you guys did or somewhere to point me as guidance or resignation? Maybe a cheer, LOL.
hope you can help me out!
Thanks in advance.
