Hi

I have a Celeron 600 and an Abit bx6r2 mobo.

The CPU runs at 9 x 66 = 600. I really would like to make it run at 6 x 100. I've tried changing the soft menu to 600(100) instead of 600(66). It didn't help....
(the computer won't start)

What else do I have to change in the soft menu to make it work ???

Intel multiplyer locks it's chips so they can only be run at their set multiplyer, in you case 9X, which means any overclocking must be done via the FSB, you should try 9x100 as it is rare for a 600 not to do this, what voltage does your chip run at by default? if it is 1.5 or 1.65 then it is a cBO chip and if it is 1.7 then it is a cCO, these are generally consideredbe the best for overclocking, you may need to up the voltage as far as 1.9v for 900mhz, and as long as you have a good heatsink and fan this will be fine. I have a cCO 600 that will run at 900 with 1.45v and runs at 1008 with 1.9v, but this is after a 2 month burn in and left me quite shocked.

So thats the reason....

I'm not sure I understood the end of Your message correct, but did Your CPU burn ? (dead and finished?) And was that at 900 or 1018 mhz

Will I be able to run at 9 x 75 or 9 x 83 ?
BTW: I have a golden orb cooler

non the chip is fine, a burn in is either a process where you test stability, ot run it really hot for a while, or run it at higher voltage depending on your opinion, I ran my chip at 600 with 2v after reading an article ( http://people.freenet.de/s.urfer/conditioning.htm ) and this allowed me to run at a lower voltage (1.3v at 600 for a cCO) you should be fine at 9x75, 9x83 could be a problem with your harddrive and vid card but you can always try it, but 9x100 should be fine, it is rare to see a 600 that will not do this, and even then it can still be achieved with a bit of work, I would say your gorb is probabally ok for 900mhz though if you have difficulties at this speed I would say that it should be your first suspect. Try 9x100 an if that doesn't work up the voltage at 0.05v at a time until it does but don't go over 1.9v especially with a gorb

In your BIOS you can also choose to Disable Video BIOS shadowing and Disable System BIOS shadowing. Disable Speed error hold if it is present, too.

Maybe someone who has that exact board can help with a couple of other settings. As Phil said, make sure you try the higher voltage being careful about the heat.

There are nice guides for beginners that you can link to from the main page of this site.

You've got one of the best chip/motherboard combos going for overclocking. You should do well with that pair.

Cooling is a very important point...If you still have the intel heatsink/fan attached, before you crank up the vcore and FSB, you really might want to consider a much better unit. Also, the thermal compound that you use between the cpu and hsf plays a major role here, as well

I found with my Celeron that, upgrading from a Gorb with the "supplied Dow Corning grease" to a lapped cpu/PEP66T/Arctic Silver thermal compound, I ran around 7-9 degress celcius cooler, and a couple MHz of FSB faster, as well.

The cooler you keep the cpu the faster is will run.

And to cap..........

Don't exceed 1.90v as some may try to get you to do - it reduces the working life of the CPU dramatically.

Very important point, also. Especially true with intel, or substandard (generic) heatsink/fans.
