I've been able to install SL on my G31M-ES2L motherboard. The only problem i've had is with the GTX275.
First the screen went black after boot. By removing the NV related kexts following the method described in GeForce GTX 260 in Snow Leopard → I am able to get to the desktop.
Actually SL behaves much beter graphics wise than 10.5. It's workable as there are no screen redraw problems etc. But of course I want full QE support. Anyone out there who got their GTX275 running on SL?

How to work GTX 275 on snowleopard with efi strings can anyone explain it. If someone has succes with GTX 275, can answer if qe/qc enabled and dual display is working? Been trying to make it work with snowleopard for almost 1 week. with efi strings I only made snow leopard to see the graphic card as GTX 275 but no qe/qc.

about that issue and guide me throug my GTX 275 installation in snow leopard.

Thanx for your helps.

Partly working...

I have a Gigabyte GTX 275 in my 10.6.1 hackintosh.
It is running fine (with dual monitors) except that I cannot run it at the full resolution of my main display (1920x1200). If I do, clicking the application folder s in the dock and scrolling the app will generally cause a crash. (well not sure if it is really a crash, the 2 screens turn off, then I can't do anything but restart). I do not get this issue at any other resolution.
I have tried EFI studio to add a string (not sure if done correctly), but it has made no difference.
As the screen looks blurry in any other resolution I would really like to fix it. Any ideas greatly appreciated.

I got an ASUS GTX275 fully working on Snow Leopard 10.6.3.

[My method]:
I created a EFI STRING (google is your friend) with gfxutil from Leopard 10.5.6 without vga kext installed (not on SL).
I added the EFI STRING (out.hex) to com.apple.boot.plist in /Extra.
Reboot.

i hope this can help.

Bye!

2 GTX 275 on SLI mode on Snow Leopard

GTX275 was working fine and I recently purchased a second one and plugged in on SLI. On Windows 7 is loading just fine but iatkos s3 crashes before desktop. Is there something I need to do or new enabler to install? The EFIStudio method would work?

The motherboard is Gigabyte UD3R with i7 920.

Thanks alot
