Guest Ramm Posted June 8, 2007 Share Posted June 8, 2007 It might be your FSB. Search around for how to change it. It might be your FSB. Search around for how to change it.

Mebster Posted June 8, 2007 Share Posted June 8, 2007 I'm not sure why the time is changing in the middle of using OS X but have the time auto update using the internet. There is an option in the Clock preference area. If however you get different time readings when you switch between OS X and XP then use one of these methods. I myself wrote am using the "Not As Clean, But Does The Job Better (Than Registry Editor Version)" which I wrote in wiki too. Let me know if this solves the problem.

meftun Posted June 13, 2007 Share Posted June 13, 2007 hi.. i'm using 10.4.8 just because of this time problem. when i upgrade to 10.4.9, the clock goes 2 times faster than it should. i don't know if it has anything to do with this but: when 10.4.8 installed, About This Mac shows my cpu clock correctly (2.13 GHz). but after upgrading to 10.4.9 it says something like 1.86 GHz. thanks for reading.

Filip100 Posted June 16, 2007 Author Share Posted June 16, 2007 i install 10.4.9 and it is again same problem Link to comment https://www.insanelymac.com/forum/topic/53370-problem-with-time/#findComment-387096 Share on other sites More sharing options...
Damedepik Posted June 19, 2007 Share Posted June 19, 2007 In my case the opposite problem occurs, my clock is 4x slower than normal Could someone give this an explaination ? My FSB is reported to be 400Mhz. I've tried with FSB=100 as kernel option but it didn't help It's very annoying because all GUI animations are slow as well...

grbrum Posted June 20, 2007 Share Posted June 20, 2007 hey guys, i had a similar problem with my overclocked pc. It is a 2.8ghz Pentium D overclocked to 4ghz, and it worked fine with JAS 10.4.8, but when I installed the JAS 10.4.9, the time was 40% faster as well. I solved this by installing Uphuck`s 10.4.9 DVD (clean install). The JAS version gave the problem. Uphuck`s didnt. hope it helps: Hardware Overview: JAS - 10.4.8 Machine Name: Apple Development Platform Machine Model: ADP2,1 Processor Speed: 4 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 1 MB Memory: 2 GB Bus Speed: 1.14 GHz JAS - 10.4.9 Machine Name: Apple Development Platform Machine Model: ADP2,1 Processor Name: Intel Core Duo Processor Speed: 2.8 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 1 MB Memory: 2 GB Bus Speed: 1.14 GHz Uphuck - 10.4.9 Machine Name: Macintosh Machine Model: Intel Processor Name: Intel® Pentium® D CPU Processor Speed: 4 GHz Total Number Of Cores: 2 L2 Cache (per processor): 1 MB Processor Features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL CID CX16 TPR Memory: 2 GB Bus Speed: 1.14 GHz Link to comment https://www.insanelymac.com/forum/topic/53370-problem-with-time/#findComment-390506 Share on other sites More sharing options...
josh256 Posted June 21, 2007 Share Posted June 21, 2007 you need a kernel that does accurate FSB detection... grab the latest NetKas kernel (on the Uphuck DVD I think it's titled "Intel SSE3 - 2"...).. or grab in in IRC (server info at http://netkas.freeflux.net I think) Link to comment https://www.insanelymac.com/forum/topic/53370-problem-with-time/#findComment-390765 Share on other sites More sharing options...
daveywilks Posted July 27, 2007 Share Posted July 27, 2007 My clocks running fast as well Although reading this point it occurs to me that I've overclocked by about 5% and the clocks about 5% fast - mmmmm. Think I may have found the cause. Thanks guys.

MoDs Posted July 27, 2007 Share Posted July 27, 2007 Change your FSB: copy the file "/Library/Preferences/SystemConfiguration/com.apple.Boot.plist" to your desktop open it and modify it to look as follows: <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>fsb=133</string> ... Just add fsb=133 then save it. Copy it back to folder and reboot.

Filip100 Posted July 28, 2007 Author Share Posted July 28, 2007 I changed but tim was 5 times faster,...... I solved problem when i changed fsb from 133 to 266,....

MoDs Posted July 28, 2007 Share Posted July 28, 2007 No problem Actually, you should see your bus speed (About this Mac->More Info), divide that value by 4, and plug in the result like that "fsb=xxx" And don't forget to always repair permissions after change Link to comment https://www.insanelymac.com/forum/topic/53370-problem-with-time/#findComment-416804 Share on other sites More sharing options...
fishyeah Posted July 29, 2007 Share Posted July 29, 2007 In my case, the system clock slows down over time, say 15 mins in several hours. Shouldn't the actual FSB speed be used in com.apple.Boot.plist? According to my motherboard spec (Abit aw8), the FSB speed is 1066MHz, but the CPU (Pentium D 930 3.0GHz) FSB is 800MHz. My hackintosh report Bus speed as 816MHz - maybe that's the reason for clock slowdown...

email_atif Posted July 29, 2007 Share Posted July 29, 2007 Any more info on this? My installation (JaS 10.4.8) is reporting the correct actual FSB for my system (417MHz). Should we just use our actual FSB, or divide the reported number by 4? NOTE: My FSB is set to 417MHz in BIOS, which results in an overall system bus of 1668MHz - Atif Link to comment https://www.insanelymac.com/forum/topic/53370-problem-with-time/#findComment-417135 Share on other sites More sharing options...
MoDs Posted July 29, 2007 Share Posted July 29, 2007 you should use the value Mac OS reports, divided by 4. That's it Link to comment https://www.insanelymac.com/forum/topic/53370-problem-with-time/#findComment-417193 Share on other sites More sharing options...
email_atif Posted August 1, 2007 Share Posted August 1, 2007 ^ Thanks MoDs. Time is definitely incrementing properly after doing that, but I still experience the (known) issue of the time being shifted several hours when switching between Windows Vista and OS X. No worries, it's just a minor annoyance I suppose until Apple works out a fix (I saw that the guys with MacBooks and BootCamp were experiencing the same) Peace Link to comment https://www.insanelymac.com/forum/topic/53370-problem-with-time/#findComment-418794 Share on other sites More sharing options...
