xpeace Posted April 28, 2012 Share Posted April 28, 2012 Hi ! I`ve got installed the latest 10.7.3 and had no problems using the AppleHDA, Apple Trackpad and Nvidia Graphics Driver. Everything was running fine until I decided to do a full upgrade from the builtin T7300 to a T9500 Core2Duo. The T9500 with 2.6gHz is one of the fastest you can put in the Machine I think, however since I replaced the CPU, Audio Stutters, and the Graphic Card feels a lot slower - when starting the Graphic Stutters as well, ... is it due a different Microcode, will a reinstall help ? Does the CPU require some new Microkernel kExt ? Any hint on that issue would be appreciated. Link to comment Share on other sites More sharing options...
Administrators Syonagar Posted April 29, 2012 Administrators Share Posted April 29, 2012 Dear xpeace, I don't think its a software issue. It may be a hardware issue. Did you check if your new cpu has similar FSB speed to the old one? Cheers! Link to comment Share on other sites More sharing options...

The T9500 Runs with 800Mhz FSB (CPU-X shows 796 MHz) same as the original T7300, but one has 65nm the other 45nm waver size, ... ? Link to comment Share on other sites More sharing options...
sipart Posted April 29, 2012 Share Posted April 29, 2012 Whats the fan activity and CPU temperature like? http://www.bresink.com/osx/TemperatureMonitor.html Link to comment Share on other sites More sharing options...

xpeace Posted April 29, 2012 Author Share Posted April 29, 2012 Thank you for your support ! CPU Temperature is 45 deg idle up to 55 deg on heavy testing, I replaced the fan with a new one and cleaned the vents when replacing the cpu, setting the Bootflag to cpus=1 made no difference. I just noticed that audio seems to work everywhere but not in youtube videos - while youtube advertisement works perfect, standard youtube videos don't work at all, only black video and stuttering audio, and sometimes a plugin error message, setting safari to 32Bit made no changes either, Anyone had similar experiences on youtube or flash player ? Google chrome also did not show any youtube video nor audio. Update: As I read Adobe Flash Player has Problems with HW acceleration. Using the Tab Bar I disabled HW acceleleration in Flash and now all Youtube Videos are running fine again, Once more Thank You all for your support. ------------------------------------------- D630 using AppleHDA and Apple PS2 Trackpad Link to comment Share on other sites More sharing options...
schmatzo Posted May 8, 2012 Share Posted May 8, 2012 Adobe should burn in hell for Flash. I'm using youtube.com/html5 for smooth video playback. Link to comment Share on other sites More sharing options...
