popophobia Posted July 11, 2008 Share Posted July 11, 2008 Hi, Just installed Mac on my desktop. Motherboard is Asus P5K-VM. Somehow the time on my computer is slower than the real time (not the time lag after reboot - windows/mac). The clock run considerably slower in Mac. One day it can run 3-4 hours off. Anyone familiar with this issue? Help would be greatly appreciated. Link to comment Share on other sites More sharing options...
SD Geek Posted July 11, 2008 Share Posted July 11, 2008 Just to let you know you're not alone, I am also seeing this problem on my Dell Latitude D830 running 10.5.2. I've just upgraded to 10.5.4, but it hasn't been running long enough for me to see if the clock is going to skew. Link to comment Share on other sites More sharing options...

borisbadenov Posted July 17, 2008 Share Posted July 17, 2008 It might be that your system is reporting a slower than normal cpu speed. This can be fixed by editing your com.apple.Boot.plist. Link to comment Share on other sites More sharing options...
popophobia Posted July 20, 2008 Author Share Posted July 20, 2008 Can you elaborate on that? My computer reports the correct speed though. Link to comment Share on other sites More sharing options...
Gujal Posted July 20, 2008 Share Posted July 20, 2008 There were two different issues causing this problem 1. Wrong FSB recognised. This can be fixed by setting up fsb=xxx (where xxx is your correct frequency) in the com.apple.Boot.plist or by using the latest patched AppleSMBIOS.kext from mac.nub 2. 45nm Core2 CPU. This also slowed the clock gradually and the fix for that is not to use vanilla kernel and using modbin patched kernel instead. Link to comment Share on other sites More sharing options...
popophobia Posted July 21, 2008 Author Share Posted July 21, 2008 Thanks, I think it's the 45nm core2duo thing. I guess I'd have to use the modbin kernel then. Thanks. Link to comment Share on other sites More sharing options...
verdant Posted July 21, 2008 Share Posted July 21, 2008 Thanks, I think it's the 45nm core2duo thing. I guess I'd have to use the modbin kernel then.Thanks. Try the command ntpd –q via Lingon......it may work meaning you do not have to switch kernels..... Force OS X to resync its desktop clock time at login by using Lingon 2.1 (download from http://lingon.sourceforge.net/) to create a Users Daemon as follows: i. Run Lingon 2.1 app. ii. Click on "New" button. iii. Select "Users Daemons" and click on "Create". Then: In Box 1 under "Name" enter ChronoSync In Box 2 under "What" enter ntpd –q In Box 3 under "When" select run when it is loaded by the system (at startup or login) and at a set intervals thereafter.... iv. Click on "Save" button and logoff and login again as instructed. Link to comment Share on other sites More sharing options...
Lucifire.Luke Posted July 24, 2008 Share Posted July 24, 2008 I would suggest changing the time in your systems bios because the OS stores time in the Bios EEPROM so may be changing time in the BIOS straight away do the trick. Luke Link to comment Share on other sites More sharing options...
