Summary0000350: System does a reboot when trying to increase FSB speed
DescriptionSimilar to this problem (http://www.bugtrack.almico.com/view.php?id=252) my system reboots when I try to increase FSB speed. After reboot the FSB indeed is set to higher speed but I guess the reboot is not supposed to happen ;-).

Anyways decreasing speed e.g. from 133 MHz to 100 Mhz works pretty well, just the opposite results in a reboot.

Steps To Reproduce1. Open tab clock
2. Select clock speed higher than current
3. Click set clock

other way to reproduce:

1. Configure Automatic Clock control
2. Set checkbox "Use this clock generator"
3. Stress CPU
Additional InformationIn Speedfan I selected K7N2 Delta-L as mainboard. Actually it's a K7N2 Delta-ILSR but I guess it makes no difference to clock generator.

The problem seems to be more complex than I thought. Setting low speed to 66Mhz and high speed to 100 Mhz works fine. Also setting 130 and 133 Mhz makes no trouble. But if I select 66/133 or 100/133 Mhz or change it manually I still get the reboots.

Whenever we apply any change to the FSB almost anything can happen. You are correct about the clock generator: it makes no difference. FSB control, with SpeedFan, doesn't change anything else (above all: dividers). This means that any FSB change works only if... it works. My suggestions is to set a different "starting FSB" in BIOS. Moving from 100 to 133 when BIOS set it to 133 is not the same as moving from 100 to 133 when BIOS set it to 100.

Hello Alfredo,

I tried your hint concerning starting speed. Didn't seem to resolv my problem. Somehow I came to that point that something with memory interacted with FSB setting. So I set in my BIOS FSB/MEM ratio instead "auto" to "1:1" and set the timings manually and.... it helped!

Now Speedfan can adjust low performance setting to 66 MHz and high performance to 133MHz.

Thanks for this great tool!

Cheers!
