Hi I have been trying to get my 260 card to work i have full quartz accelration but when i load a game like enemy territory all i get it snow like a tv tuned to a channel that isent there

 

I have tryed several custom snow leopard discs and the retail disc using the 123 boot method

 

my mother board is asus p5ql/epu

i have also tryed a gigabyte p35-ds3r

same results

 

if i put my gtx 8800 card in everything works fine

 

has anyone ever heard of this problem or know how to fix it please help.

 

Thankyou

Scotty

Sorry I have searched and have not found anyone else getting the snow problem i am having.

 

so you've tried GraphicEnabler=Yes ?

 

and you tried adding a GFX entry to DSDT ?

 

and you've tried the GFX strings PCWiz has posted on infinite mac ?

very odd:

 

what method are you currently using for injection?

Have you made sure to clear caches when removing NVEnabler or similar?

what port are you connected to (DVI, DSUB etc.) ? and have you tried the other ports?

what resolution is the game tring to run at ? and i presume you've tried more than one game?

 

Snow is an analogue video fault as digi either works or it doesn't.

Im using DVI and I have tryed analouge as well.

I have tryed alll the different injectors

I have tryed putting the GFX String in the boot plist

I have tryed using the Chamelon Graphics Enable

It does it in every res I have tryed the only game i got to work and not show snow was assault cube.

I am just about o pull my hair out lol

I dont under stand why it wll work with my 8800 but not the gtx 260 i even tryed a 9800gt and it has the same problem as the gtx 260.

I have tryed two different motherboard too same issue.

I have tryed MBR partition scheme and guid.

Any Ideas ??

 

Maybe if someone else with a Zotac AMP Edition GTX 260 could send me there configs maybe I did something wrong with making mine

Or if some one with my same asus motherboard could send me their dsdt every time I try to make one i get some compile error.

With the 8800 card it is just so simple all i have to do is inject the gfx string with efi studio.

Looking at the Zotac website you card has Dual DVi ports, is that correct?

 

If it is please try this code in your DSDT:

 

Use IOregexplorer or lspci to find the correct place to insert the code. Remember to remove any enabler kext and clear caches (snow leopard cache cleaner is very easy way to do this.) and set GraphicEnabler=No in info plist.

This has happened to me a few times. Happens mostly if Snow doesnt detect a monitor plugged in. Now does this snow come on normal OSX use?

 

I would suggest you update to the 10.6.4, apply the Graphic Patch and restore all NV related kexts to default.

 

Once done remove all NVEnabler etc type of kexts and just use EFI Strings to get your card working. My GTX 260 works with just EFI Strings. Nothing else. No other modification. Period.

 

I get full QE/CI even during setup because of this, not that it matters.
