Hi people there.
I am new to the forum but not new to hackintosh.
In 2012 I bought a dual xeon 5420 with a tyan board that run successfully os 10.6 for some years. This with a iatkos installer. Then I made a fresh install of 10.8 again from iatkos that runs great as well.
This success led me to buy an intel s2600cp board with two 2670 xeons and 128 gb ram.
I installed iatkos ml2 on it and it boots fine but the activity monitor only shows 3gb ram. The rest os the system and apps see 128gb, but it will crash when attempting to use more than 3gb, so I think activity monitor is right, and not the system profiler.
I have also tried niresh mavericks. It installs and runs great but can´t seem to make the gtx660 work. It works in 10.9 but without any acceleration, and updating to 10.9.5 and using nvidia web drivers makes the screen freeze all the time (the mouse pointer still responds a bit). This is with ge=no. I have also tried ge=yes but I think it just got to a black screen. I have tried all sort of stuff but nothing seems to work. Was using chimera 3.0 and now switched to clover wich has far too many options.
One thing I notice is that the screen seems to crash in relationship with disc activity. The more drive reads the more it freezes.
There are thousand things I could still try, like different bootloaders, pci slots, graphics cards, freezefix app, etc. But before I loose all of my hair I tought I should ask here if anybody is familiar with this board. I have read of similar builds but not a single one with the s2600cp.
I don´t have experience with other installation methods like dsdt or creating a custom installer, just niresh and iatkos. Thought they should be fine as I got past the installer easily.
Would be glad to help if anybody is on the same boat.
Thanks in advance.
