mathdude1284:
That's exactly what I get with 7900GTO and I think that's what most others are getting too...

I't starting to look as this is a 512MB problem... I wonder if it would be possible to flash the card to think it only has 256MB memory, but otherwise work as usual? :)

Just found out about Titan today. Exciting news! Could someone please tell me if my Geforce 6800GT AGP will work? If not, my mobo also has PCI-E so I'd be willing to get < $200 7x00 series (maybe that silent 7600GT)

zam.. does it say that ur card is 512mb in darwin? or in system profiler?

also.. ive found success when deleting NVDAResman.kext.. (That causes dependancy issues with NVDAN40Hal.kext so that may be the offending kext too)

When NVDAResman is removed, I get pretty stable gfx, but no QE..

Nope, at least system profiler sees it as only 256MB. This was tested using only vesa drivers.

same for me.. im convinced the reason this isnt working is because the kexts have compatibility issues with 512mb cards.. If only we could hack those kexts..

My card has 64mb...so i dont think it has to do with 512mb problems...maybe the way it handles the memory?

ok.. more info that i think we need to check some more infos..

After reading all the stuff on omni's site, it says that

The keys under the display@ sub-tree that need to be set BEFORE NVidia kexts


So does that mean titan.kext needs to load before NVDANx0Hal.kext and NVDAResman.kext? Because NVDAN40Hal.kext loads much before titan.kext in my setup..

Feel free to add your non working cards to the wiki page:
http://wiki.osx86pro...x.php/Titan#HCL


Dax, would it be possible for you to add a vram column to the wiki? (or at least a message encouraging people to mention it). Theres only about 1 or 2 people who have specified how much onboard ram their nvidia cards have.. It seems with the issues some people are having, it would be good to see if memory is a factor.

there.. i added in the VRAM column..

also mathdude, i tried to add titan to load before nvidia by manually setting it in the rc, but it still doesnt show anything.. i just think this is a NVDAResman issue

I feel like im beating a dead horse..

as far as i know dm_webd is working on implementing the suggestions _np made, that might make our 512mb cards singing again :-)

EVGA 6800GS 0x00c010de either kernel panics or locks to a black screen.
Tried Titan and Natit.
Got close but tried everything without success.
Remove Geforce.kext, added card id to NVDANV40Hal.Kext and NVDAResman.kext wich allows me to a dual display setup using Natit.
I can change resolutions and both of my LCDs work (Dell 2407 1920x1600 DVI + 10" on 1024x768 VGA).
No hardware excelleration though.


I finally got it working.
I found a Titan Torent on a popular site.
I copied all files from that package to my extensions folder.
Repaired permissions, added my cards ID to Geforce, NVDANVHal40, and NVDAResman.kext.
Rebooted and it's working with excelleration.
I kept the Natit.kext and remove the Titan for my dual monitor setup.
I must have had a bad kext or a different version of one of them.

Club 3D nVidia 7950GT 512 MB Fails with Titan on both 10.4.6 (10.4.8 kexts) and 10.4.8.

Added EDID in Titan, vendor and device id into NVDANV40Hal.kext.

Without vendor and deviec ids, famous blackscreen appears.
With vendor and device ids, login screen crashes, says "restart your pc".

Haven't tried macvidia or natit (yet). Lost all hope :(
