Do I need to change anything to run 2 x GTX-240?

[jimbaran]

I have one GTX-240 now and it can drive my one monitor fine but it stutters when I plug in the second.

Can I just throw a second card in or do I have to insert some kexts?

Monitor one is 1920x1200(DVI) monitor two is 1920x1080(HDMI) - Just too much for one little graphics card I guess.

Sorry for my noobness.

Thanks

Jimbaran

I am not sure if you have to add another string to the DSDT, though. I hope someone with more experience will chime in and let you know if the DSDT needs editing or if a modified "/boot" file is enough. I am not sure if the newest chameleon contains the graphicsenabler or if it is OSX native.

Have you tried plugging in both cards yet?

A DSDT edit will be needed for sure- check out Jocelyn84's thread here- she's got the same setup:
