stellarola Posted January 26, 2009 Share Posted January 26, 2009 I don't exactly know whats up with my card and either of the provided Mac Pro 8800GT bios. It's just not stable for me, personally. My motherboard bios is showing different characters where others should be and also some artifacts as well. 2D3D bios works pretty ok, but is fairly unstable with my card. 3D bios doesnt even let me play around with the OS before it freezes.

leslieking Posted January 26, 2009 Share Posted January 26, 2009 Glad to see the problem is in the works for a widespread fix! For now, I will have to deal with it. I have a 8400 GS, and the lag problems as well. Yes, I think all 8xxx card are affected Link to comment Share on other sites More sharing options...
roidm Posted January 26, 2009 Share Posted January 26, 2009 I´ve flashed my GTS with the 2D3D bios and i´ve changed the clocks, volts. etc... to the GTS values ... all is working fine on leo and Snow... thx Link to comment Share on other sites More sharing options...
leslieking Posted January 26, 2009 Share Posted January 26, 2009 In worst case I remove Quicktime.. Sorry for my post, but I think this is the crapest software I ever seen, VLC is much better. Any problem happen if Quicktime is completely removed with CleanApp ? In other words, any program is quicktime dependent ? Link to comment Share on other sites More sharing options...

cyclonefr Posted January 26, 2009 Author Share Posted January 26, 2009 Compare your original bios with for example 2D-3D bios, and put the same memory timings (all 7 of them), same boot up clock, same t°/fan speed, same perf table (although i couldnt edit the 4th one) and then retry, it could work. I have no problem at all and tried games etc. I don't exactly know whats up with my card and either of the provided Mac Pro 8800GT bios. It's just not stable for me, personally.

leslieking Posted January 26, 2009 Share Posted January 26, 2009 Thanks cyclonefr for your work! I think we need a wider solution soon because some users have 8400, 8500 and 8600GT cards. Now, I don't want to downgrade to GeForce 7300GT. This quicktime lag is a real nightmare Link to comment Share on other sites More sharing options...
mitch_de Posted January 26, 2009 Share Posted January 26, 2009 I am an interesting reader of the Mouse Lag problem. Q: What has QT 7.6 to do with the GPU type used ? Link to comment Share on other sites More sharing options...
Master Chief Posted January 26, 2009 Share Posted January 26, 2009 I am an interesting reader of the Mouse Lag problem.Q: What has QT 7.6 to do with the GPU type used ? Apple apparently calls BIOS feautures that are not available; in for example the installed 8600GT/512MB but in their own 8800GT. I wonder if the browser plugins for Safari/Firefox are affected as well, or that it is the QT core only. Link to comment Share on other sites More sharing options...
leslieking Posted January 26, 2009 Share Posted January 26, 2009 The same problem happen on 8500GT. This problem affect a lot of 8xxx cards. Not only the 8800GT and 8600GT is affected. If Apple call BIOS feature that are not available why older cards work ? For example 7300GT... Link to comment Share on other sites More sharing options...
SA22C Posted January 26, 2009 Share Posted January 26, 2009 The same problem happen on 8500GT. This problem affect a lot of 8xxx cards. Not only the 8800GT and 8600 are affected. If Apple call BIOS feature that are not available why older cards work ? For example 7300GT... Well, older 7xxx cards probably work because the problem is caused by a feature that Apple added to the 8xxx series cards found in the MacBook Pro and Mac Pro. My activation woes were solved by a terse phone call to the automated Microsoft activation line. This is not the first time I've had to call that line, and this probably won't be the last. I've got a copy of XP Home that I purchased back in 2002 that has probably been installed on 20 machines over its lifetime (Never more than one at a time) and it's long since passed the time where I can activate it without calling Microsoft and yelling at the rep to just activate my legit copy already. I've played some games in Windows and run benchmarks in OS X. All appears well and the flash seems to have caused no issues with non-QT performance. It also bears mentioning that this isn't the first BIOS flash needed to run OS X on nVidia cards. Back in the dark ages of Tiger, nVidia cards with 512 MB of video ram would not run correctly and required a BIOS flash to correctly report the available video ram to the Darwin bootloader. This issue has long since been resolved at the software level, but back in 2006 the only way to run a 512 MB nVidia card was to flash. I had a 7900 GTO back then and was one of the first people to try gotoh's fix. Link to comment Share on other sites More sharing options...
iRipper Posted January 26, 2009 Share Posted January 26, 2009 I think I'll wait for Snow Leo and Quicktime X. Maybe it won't have this issue But keep up the good work guys, maybe we won't need this dangerous flashing process. Link to comment Share on other sites More sharing options...
leslieking Posted January 26, 2009 Share Posted January 26, 2009 Is possible to run a new OS X release in future (for example 10.5.7) with older quicktime ? sorry for the stupid question Link to comment Share on other sites More sharing options...
Gidi Posted January 26, 2009 Share Posted January 26, 2009 Thanks to all people who worked with this fix. I flashed my 64K 8800GT with 2d3d.rom, but I also experienced bad frame drops using Exposé. After setting all clocks for 2D to 0Mhz (as the original card is), I managed to get rid of them. Now I think I have a 100% working machine. Cheers!

macgirl Posted January 26, 2009 Share Posted January 26, 2009 I´ve flashed my GTS with the 2D3D bios and i´ve changed the clocks, volts. etc... to the GTS values ... all is working fine on leo and Snow... thx I saw that nibitor could add values for 2d and other states. Could that make the 9800GTX bios work? Link to comment Share on other sites More sharing options...
netkas Posted January 26, 2009 Share Posted January 26, 2009 if u set 2d freq to 0/0 - then better to use 3d bios. it will act same after all. 9800GTX i think will work, since 8800GTS512 works, it's basicaly same cards, tune clocks/voltage/deviceid in nibitor and try. p.s. woot at my posts number Link to comment Share on other sites More sharing options...
Leoopardoo Posted January 26, 2009 Share Posted January 26, 2009 Here are my results... I've flashed my card (Gigbyte 8800GT - GV-NX88T512HP) using 2D3D.ROM since I also have 64k ROM. I've got rid of all issues in OS X (no more mouse lags... and no more ugly corrupted background image showed during boot). HOWEVER, I have gained various strange graphical artifacts in lower resolutions (e.g. in BIOS or during apple boot screen) - small dots or pixels with different colors. Even after restoring all settings (frequencies, timings, etc.) from my original GFX bios. Only way how to get rid of it is to flash back to my native bios....

cyclonefr Posted January 26, 2009 Author Share Posted January 26, 2009 Unfortunantely it seems it doesn't work well with all geforce then, specially the 64K ones.... Try the 3D.ROM, maybe it'll work good for you in the bios. Link to comment Share on other sites More sharing options...

leslieking Posted January 26, 2009 Share Posted January 26, 2009 SoSa good question Im interested in 8500GT solution. I think 8800GT is the only working card. Link to comment Share on other sites More sharing options...
cyclonefr Posted January 27, 2009 Author Share Posted January 27, 2009 9600 GT isn't affected (G94) by this problem as far as I know. About the bugs that people have, I'm not sure what to do, it seems not all 8800 GT are the same, and in your case it doesn't like that firmware. Well if it's only dos characters that are affected but not OSX, then I guess it isn't horrible. Link to comment Share on other sites More sharing options...
