Hello everyone.

I have updated my GTX 560 DC with a brand new EVGA GTX 660 Ti SC. Even though I try to set up my system, as I used to, I have a problem with the startup.

As soon as the computer starts up to Mountain Lion, the screen turns black and it restarts. I tried to set "GraphicsEnabler=No" to boot.plist and I still have the same results. What do you think are the optimal settings on Multibeast for the GTX 660 Ti, in order to solve this problem?

Is there any connection with the motherboard [Asus P8P67 Pro B3 ] I'm using?

Any recommendations would be greatly appreciated. Thanks a lot for your time, guys!

Need more concise information. What bios are you using, is it the latest? Are you using a DSDT.aml? Are your bios settings correct? When you say setup your system like you used to, need details. And then maybe we can help.

Hello!

- The bios version is the 80.04.4B.00.60 / I have never updated the bios, I never had any problem with Bios.
- I am using the DSDT.aml for Asus P8P67 Pro B3.
- All settings in Bios are correct.
- The system starts us up normally, but when I choose with bootloader either Mac or Windows and I choose Mac, I see the Apple logo and then the screen turns black and restarts.

Perhaps I may not have made correct modifications on Multibeast, I really don't know and makes me desperate...

Does this happens in both windows and mac? When starting hit the spacebar when you see the tonymac boot screen. Then try booting with these boot flags all at the same time.

-v GraphicsEnabler=No npci=0x3000 if that doesn't work try -v -x GraphicsEnabler=No npci=0x3000
-v may allow you to see what activity is taking place before the reboot.
Also check your bios settings in integrated peripherals, that you have your hard drive mode set to AHCI. Try these things then report back.

Thanks a lot for the help! I followed a totally unexpected solution. I restored my system to an older 10.8 version, used the GraphicsEnabler=No and worked. Works great with bootloader installed. Do you happen to know how am I gonna install openCl for this card? I used all procedures and still Luxmark notifies me that "No OpenCl device installed". Why this is happening?

Followed exactly this and still the Luxmark says that "No OpenCL Device Selected or Available". For some reason I cannot enable OpenCl...
Did you install the kext for cards greater than 2 gb, that is on Multibeast 5.0xx If not do so, and If that does not fix it, then there is one other thing you will have to do t. Heres is the link. http://netkas.org/?p=1161 It is very easy to do.,

I have done both things and what I see is that when I replaced the original OpenCL with the modified one, when the Apple Logo appears, it stops there and I cannot login to the OsX... Weird things, but really thanks for your help! I appreciate it. Is there any way to install OpenCl flawlessly?
