CPU noob problem

Hello people :-) , i've got the following problem:

I've got a Intel Celeron 900 Mhz
Only thing is, the bios says 600 Mhz (9.0 x 66.8)
The jumper of my computer has 4 stances: 66, 100, 133, auto (auto =100)

When i set to 66.8 (what i normally have) everything works fine, but when i change to 100,133, or auto my frequency changes to 900 which should be good because my processor is made for 900; but it isn't, cuz when it's set to 100,133, auto, my computer crashes/freezes.
Even at scandisk in DOS (when i have not shut down the computer properly)

Has this problem something to do with the core voltage? or perhaps a virus?

Thnx Misha

Ps. Sorry for my crappy English
 
It might need more voltage. Running at 600MHz requires less power than at 900MHz, so if you don't raise the voltage that can cause problems.
 
Are you moving it into a new computer or did it just start going like this or has it been like this since you bought it?
 
Thanks for the voltage thing, i'll try it, and let you guys know if it works.
B.t.w. my voltage is now on 1,70 (that says a hardware monitoring program from the motherboard manufactor)
In the bios it says 1,75... if i change my frequency from 600 to 900, how much should i raise the voltage then?

Acctually to be quite honest, i found out yesterday that i have a Intel Celeron 900 Mhz, i always thought it was 600, because it it set like that in the bios.
I never bought this comp. i got it from a friend of mine.

Anyone has other solutions than voltage?

how did you find this out??

What we need to find out is what the voltage required for you cpu is, 1.7 (if that correct is pretty high the celeron 900mhz shoud run on 1.475v

What does cpu-z say??

1.7 is fine, if anything it is on the low side. Williamette P4s operated on 1.7 this celeron is P3 based (probably coppermine)

thought it was on the PGA370, which i thought ran celeron 900 and 1.475
 
So it isn't the core voltage... some other resources told me that i havn't got enough memory, or that my cooling isn't good enough...

Maybe you guys can help
 
Ah there's where they put it :) One problem though: it's not necessarily a 0.13 micron chip, those would be the ones fabbed during the tualatin era.
 
YEa i dont think its your memory, if you have at least 128Mb you should be fine (256mb for windows xp). How long can you run your computer before it crashes, and what activities are you doing when it crashes? Also if i was you i would take the heatsink off and apply some new thermal paste or pad, because you might be overheating your processor.

When i boot my comp with the 100x9 = 900 setting... the computer already crashes in Scandisk.... or today even when i was viewing my bios settings...
When i skip scandisk, windows runs for like 30 secs... everything freezes after that, and can't press ctrl+alt+del anymore

An other remarkable thing is that when i press reset (with the 900 Mhz setting) -half of times- my monitor doesn't give a signal... when i reset again... it sometimes gives signal... and then the whole freezing story goes its way...

And it isn't the temperature.... it costantly stays around 38.

Problem ISN'T solved yet... Misha
Sorry again for my crappy English
 
I read on a dutch forum that when i have a 66 mhz memory in my pc (2x 64 MB)
That that could be the problem when setting FBS from 66 to 100
 
i would tend to agree that its a memory related crash when you increase the FSB.
you should go into the bios and select a lower memory frequency and see if that sorts it out. If not try to get hold of a stick of 133 sdram and put that in there
 
Question 1: How do i change the memory frequency?

Question 2: I have 2 memory cards: 2x pc-100 64MB
When i set my FBS to 66, and put only memory card A in it; Then change the 66 to 83 in the bios (the FBS); The computer freezes immidiately

When i set my FBS to 66, and put only memory card B in it; Then change the 66 to 83 in the bios (the FBS); The computer works without crashing!

EDIT: I've done this test again, and now they both work.... and now, when i set to 80 X 66.8 my computer doesn't give a signal

WTF

judging by what you have said about changing the frequencies it sounds more like you are overclocking the system. you need to go into the bios and look for something called advanced chipset feature, then you're looking for something like DRAM frequency, i expect yours is set to automatic at the moment, you need to change it to 66 (even though it should work at 100).

also, going on what you said about your 2 sticks of pc100 ram im guessing that one of the sticks are knackered. they should both work at 100 MHz without problems. if you are going to get some new ram try and get some 133 and then you shouldn't have any problems with your system crashing when you increase your FSB.
