Recommending a cheap Fermi (CUDA-enabled) card for Hacks

Just picked this up to replace my second hackintosh's ATI4850, which always crashed my system when trying dual-dvi in OSX. this GT440 has a single-slot cooler, works great with CUDA apps like Adobe Premiere (if you're into video editing), and doesn't require an external power cable.

It's far from the best gaming card to use - it is under $100 after all - but it works great in both Snow Leopard and Lion with the latest Chameleon boot loader and GraphicsEnabler=Yes. Both DVI ports can output at the same time (haven't tried HDMI yet) and there don't appear to be any freezing issues with this card.

Highly recommended if you're on the market for something that just works, and is cheap. Hardcore, gamers turn elsewhere.

I just replaced my Batmobile 5770 with this card, Zotac GT440 2xDVI+ 1xHDMI.

I am using 10.7.1 with Chimera 1.5.2.

Using GraphicsEnabler=Yes the monitor goes to sleep when login screen appears. I can not wake it.

Using GraphicsEnabler=No works, but I am stuck at 1024x768.

I was hoping this would work OOB... Any ideas what to do/try?

ATY_init.kext solved my problem (with GraphicsEnabler=No). My 2 x u2711 are connected using dual link DVI and work at full resolution 2560 x 1440. Launchpad wobbling is present.

I still do not know why GraphicsEnabler=Yes does not work.

that's odd, did you set your PCIRoot=1? i'm also not familiar with the latest version of Chimera, i've been using the latest version of Chameleon through Chameleon Wizard for the last few months.

But glad to see that you got it working! I have both DVIs in use as well, one to my HDTV, the other to a monitor. oddly enough, the card also hasn't crashed at all under 10.6.8, something which most other Fermi cards would've succumbed to by now.

Yes, I have tried PCIRoot=1.

Since you use Chameleon Wizard I used it to install the latest version of Chameleon, i.e. "Chameleon-2.1sv-r1508". My /Extra/org.chameleon.Boot.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

        <key>EthernetBuiltIn</key>
        <string>Yes</string>
        <key>GraphicsEnabler</key>
        <string>Yes</string>
        <key>Kernel</key>

        <string>1</string>
        <key>Timeout</key>
        <string>2</string>
</dict>
</plist>

Same result, screen goes to sleep when login screen should appear. There is no way to wake it.

What am I missing?

When I use ATY_Init.kext for injection my system information shows (sorry for Swedish):
