Hi all,
I've recently put together a nice little beast with the following specs:

Asus Rampage Extreme IV
Intel i7 3820 3.6GHz Quad
32GB Corsair Vengeance DDR3 1866 Quad RAM
240GB Force 3 SSD HD (Partitioned down the middle - half for Win 7, half for Lion)
2TB Seagate Sata3 7200 HD
Corsair TX2 750W PSU
Funky H30 Liquid cooling setup.

This is the most I've spent on a puter since buying a G5 about 8 years ago (still works beautifully).

I also have the following GFX cards:

GTX285
Radeon 4850
**Zotac 9800GTX+**

The 9800 is the card I've got plugged up and ready to go as I was informed that the GTX285 isn't actually supported under hackintosh conditions, despite it being supported by an actual Mac Pro.   Shame, as it's really quite beefy.

I've installed Lion using myHack, installed Chameleon and got it booting from the HD all fine and dandy and using a modified AppleIntelE1000e.kext, I've got the ethernet working also.

However, I can't get the 9800 to work fully.   When booting up with a plain ...boot....plist, I get the horrible resolution.   If I add GraphicsEnabler=Yes, it will boot up to the point when the desktop usually appears but then the screen goes dead/no input.

I have tried this with 10.7 and 10.7.3.

Could anyone give me any advice on where to go next?


Huge thanks in advance!

Have you tried other DVI output ?
I would use GTX 285 instead 9800 GTX - much faster + less power consumption.
9800GTX+ have huge power consumption and mostyl die after 2-4 years (lots of non working / problematic  9800 GTX / 8800 GTX in ebay!)
GTX 285 normaly works  well since 10.6 + newer Chameleon (1/2 year + less)
Only GTX 275 has some problem for my knowledge.
