hackeron Posted June 25, 2008 Share Posted June 25, 2008 It seems quite a few people are having problems with the Q9300 and Hackintosh (personally running 10.5.3) - the system clock loses around 5 seconds a minute which creates a heavily out of sync clock over time, audio distortion and jitter in many players, causes jitter on the usb and an array of other clock related problems. Has anyone managed to find a solution for this?

hackeron Posted June 25, 2008 Author Share Posted June 25, 2008 After weeks of being tortured by this, I finally found a solution: This is a message to all Q9300 and other 45nm chip hackintosh users, if you are plagued by the following problems: Slow system clock Slow RTC Distorted jumpy sound USB jitter (and therefore no sound or occationally distorted sound for usb devices) Movie players like VLC not working correctly or at all Many other problems relating to time not being correctly calculated (e.g. better benchmark results than expected!). The solution is to stop using the vanilla kernel, it has problems with many 45nm chips - Download "Mac OS X Leopard 10.5.3 Kalyway Combo Update" (google it) Install the 9.3.0 modbin kernel Edit /Library//Preferences/SystemConfiguration/com.apple.Boot.plist and add the -64_bit Kernel Flag (e.g. <string>-v -64_bit</string> under the Kernel Flags key) Reboot and enjoy having all of the above problems fixes Link to comment https://www.insanelymac.com/forum/topic/112531-q9300-other-45nm-chips-slow-system-clockrtc-and-distorted-sound-solved/#findComment-796660 Share on other sites More sharing options...
Red Oak Posted July 1, 2008 Share Posted July 1, 2008 Are you able to sleep with the Modbin kernel? Otherwise it has fixed my clock issue and my sound issue.

Lolrus Posted July 6, 2008 Share Posted July 6, 2008 Holy {censored}, I've been having constant problems with crackling/popping noises on ANY soundcard I've tried (USB,FW,onboard) so I'm about to try this and will be extremely happy if it works!

Lolrus Posted July 6, 2008 Share Posted July 6, 2008 Well sound doesn't seem to be perfect but it's definitely better using my Xonar USB card now. Far less noises. Has anyone tried the 9.4.0 kernel?

dasefx Posted July 17, 2008 Share Posted July 17, 2008 I tried the 9.4.0 kernel but no luck with the Creative xMod external USB, still cracking and weird sound from every game i try.

relikwie Posted July 22, 2008 Share Posted July 22, 2008 Hi, does it seem that the clock/rtc issue is only there with 45nm in combination ith the GA-EP35-* mainbord or is it just me. I have ordered the EP35-DS3P but still to decide on CPU. If it is the combination that causes these issues than I'am afraid later updates of OSX won't help.

kramer2k Posted August 18, 2008 Share Posted August 18, 2008 My system (e7200) starts to act funny and becomes non-responsive whenever I start using iTunes, other than that, it runs good. But can't figure out why itunes gets all flaky and causes a system to become non-responsive... EDIT: scratch that, I'm getting the NVChannel(GL) error with my new 8800GT ...Blaaast!

Could you detail if you've done anything else differently? I did this exact same thing by following a guide before. The guide said it was installing efi this way, and I have all the above mentioned problems. Btw this is not really a FIX but more like a workaround. A fix is when I don't have to reinstall the entire operating system again because you were able to trace down the problem the os is having with the timings. (and also works every time.)

crackpipe Posted September 21, 2008 Share Posted September 21, 2008 modbin 9.3.0 saved me i was having the clock problem and didn't realize that it was related to the audio, logic would give me the error synchronizing audio and midi, and whenever a song would start, it would be static and crack for a few seconds then it would play normal thanks hackeron what was the purpose/relevance of adding -64 to the boot.plist Link to comment https://www.insanelymac.com/forum/topic/112531-q9300-other-45nm-chips-slow-system-clockrtc-and-distorted-sound-solved/#findComment-899553 Share on other sites More sharing options...

Datoshing Posted February 14, 2009 Share Posted February 14, 2009 I have the E8500 (45nm), and my clock is running fast, Logic gives me sync problems every time I start recording. I'm using 10.5.6 right now, will the modbin kernel fix the time problem, and if so where may I find it? Thanks in advance.

Nuifrkns Posted May 12, 2009 Share Posted May 12, 2009 hackeron, Your post solved my problem with sound and clock timing on my Q9300. I exchanged the Vanilla kernel that came w. Kalyway 10.5.2 with a modded kernel on the same install disc and everything is running fine. Oh, and Logic does not have any sync issues anymore! A non-syncing internal clock seems like a big issue, remarkable that besides these above issues everything was running smooth and stable... Haven't tried 'sleeping' but I don't really care as my system boots in less than 30s, so why bother. Thanks for posting!
