haysoos123 Posted August 5, 2008 Share Posted August 5, 2008 Hello folks, I'm wondering if I'm missing something or going crazy. I've finally gotten an new osx86 build going with an EVGA 8800GS 384 mb, updated to Leopard 10.5.4. I searched around found this solution: put the correct device ID (in this case, 0606) in three different kexts: GeForece.kext NVDANV50Hal.kext NVDAResman.kext and then found a working GFX EFI string for the card (not using NVinject). I booted up with -v -f flags in the darwin bootloader and... IT WORKS with full acceleration with CI/QE. Great, I think everything is good. HOWEVER, it only seems to work properly if I boot with the -f flag to rebuild the kext cache! If I let it boot normally, quartz extreme is turned off and the video performance is really sluggish. I've tried to touch the extensions folder, delete the Extensions.mkext to have it rebuilt, and it STILL only boots up properly with the -f flag. Am I missing something? Why would it only work if I tell it to rebuild upon boot each time? Kalyway 10.5.2 updated to 10.5.3 then to 10.5.4. mobo: Gigabyte GA-EP35-DS3L, video: EVGA 8800 GS 384mb, 750GB SATAII Samsung HD, LG 20x SATA DVD Writer. Onboard sound and ethernet working, etc. Link to comment https://www.insanelymac.com/forum/topic/119481-8800gs-384-mb-w-quartz-extreme-only-on-extension-rebuild/ Share on other sites More sharing options...

haysoos123 Posted August 5, 2008 Author Share Posted August 5, 2008 Hey, i have the same card, working without probs here (full CI/QE), booting without any flags. well, what did you do to get it to work? Sounds like you're also using an EFI string... is that all you had to add? Did you tweak the other kexts like I did? The card works great, but I have no idea why it only seems to work with full acceleration only if I tell it to manually rebuild the caches.

No changes to anything. Just start EFIStudio, add the 8800GS to the Boot.plist, and your ready to go...
