Zotac GT 440 in 10.7.2

[Noodle]

Hi All,

I bought a Zotac GT 440 1G DDR3 (two DVI + mini HDMI) to replace my old 8600. After rebuild dsdt (somehow many address changed). Everything working fine, even recognize two monitors, but only half memory recognized.

I searched many places, get different solution (mostly using Natit.kext). But most of them will only make system recognize video card, but no QE/CI works, and it will not recognize two monitors.

Anybody know a way to make it work? Also, does GT 440 support hardware accelerate on H.264 decode? I install CUDA driver, but how do I know it works?

Thanks for your advice.

I just installed with same card. On 10.7.2. Using the top DVI output, I get full resolutions (1920 x 1080), but also show only 512K memory on video card instead of 1GB. These cards use DDR3. In 10.6.8 and on Snow Leopard install, resolution was 1024 x 768 until Lion installed.

So any help to correct video board memory problem would be nice.
