Nvidia GTS250 SLI 64bits

[gnomesgames]

Hello,

 

I've just bought a new hackintosh with an Nvidia GTS 250 SLI in it. But currently the SLI only work in 32 Bits mode (with NVInject), in 64 Bits mode i get an kernel panic at boot. I can get in 64 Bits mode by disabling one of the cards.

How can i get my SLI working under 64 Bits ?

I really need 64 Bits because the driver for my ethernet card works a lot better in 64 Bits (speed are multiplied by 5).

 

Config :

• 2x PNY GTS250 (1024mo) SLI
  
• Intel i7 920
  
• Gigabyte x58a-ud5
  
• 2x64Gb SSD (Soft Raid0)
  
• Chameleon 2 on a USB Stick
  

Thanks.

 

EDIT :

Solved ! Thanks to this guide : http://www.insanelymac.com/forum/index.php?showtopic=183349

Just followed the steps, google a little for iasl and gfxutil, and it work like a charm (64 Bits, QE/CI/OpenCL) !

 

EDIT 2 :

Not completely solved... See below.

I've tried a few games (Portal and Fable I), and the performance aren't great (Portal is playable but with low video settings).

I think that the games only use one of the two cards (the one with the screen plugged in) and not the SLI.

On windows the performance are far greater with SLI activated (run Mirrors edge with full graphics very smoothly).

 

Is this any way of getting SLI activated on OSX too ?

OS X does not support SLI/Crossfire you can have the two cards working for just plain simple extra displays connected to the outputs you will not get an extra benefit of a second card assistance in the rendering.

Ok, thanks for the reply.

Hope someday Apple will give us that...

Its sort of odd, but Apple doesn't seem to care too much about graphics performance. I've noticed through the years that Apple always puts old or slower graphics chips in all but their high end Mac Pro computers.

Yes but i have seen recently that more and more mac come with dedicated low/middle graphics cards (Nvidia 320 etc...), and their is an increase of the number of games available/ported to mac as the mac share grow.

Maybe this will push Apple to improve game performance of their machine by supporting technologies such as Nvidia SLI and ATI Crossfire.

If i remeber correctly, steve didn't want games at first on the iPhone, and now it's what push iPod touch sales, so i think they will come to it .
