Improper Frequency Combination: What's it supposed to be?

[hackmole]

I have a Pentium 4 northwood 1.6ghz computer on an Asus p4s333-m motherboard. Every day I have a lot of trouble booting up. After 4 or 5 seconds powering on it powers off. I have changed the power supply and battery and upgraded my bios and it hasn't made any difference.

After the failures to power on, when it finally catches and does power on, it takes me to a bios screen that says something like that it tried to start up at an improper frequency combination. The freqency settings I remember from the two different settings were 2100 (there was an option of I think 2600 or 2700) and another setting I remember was 100mhz by I think 133 and I had it set on manual. What are the correct settings I need or is something wrong with my motherboard?

The fsb stock for the 1.6ghz P4 is 100...the memory likely was set at 133 for 266mhz ddr or standard PC2100...

however you could set the memory to 100 as well and it would run PC1600 speed...

The main thing with the 333 SIS chipset is that it supported PC2700 or 333mhz ddr...It should give you a bios option of 166...


If you had cpu set to 133 it would hav ebeen trying to boot the cpu at 16x133 or 2.128ghz....That could have been the issue.

OK, thanks, I'll check into that.

I just ran PC wizard and it gave me a whole bunch of stats. Does this mean anything
to you that might mean something?
