Not sure how to handle this 733 Celeron...

[Ivan the Protagonist]

I've got me a 733 Celeron (66x11, and it's stuck at 11x, of course). I can 100 or 133 with the front side bus, but I'm not sure I could safely do 133, since I have two 64mb ram sticks; one is PC133, and the other, who knows?! but it can't be any less than PC100, I figure (is there any way to find out? it's not marked on the stick).

So anyway, if I do a 100FSB, that puts it at 1.1GHz. I've actually tried _just_ changing the FSB setting this way, and it won't boot (Windows Protection Error), so I figure I need to ramp up the voltage. Am I right?

But the big question is: Won't a voltage increase make my chip into a little hotpad? (or a puddle? =)
Would it be wise to set up a safety net? (i.e. Motherboard Monitor and SHUTDown Now! paired to shut off the system if the temp. hits the roof) and run the chip without changing heatsinks just to see how much cooling I need? OR: Should I just cool the chip as much as possible?

Also, I'd like some advice on doing water cooling. It's something I'd like to consider.

That's a super high multiplier so I dont think the 733s are gonna overclock well. But it may be a cD0 so that may be a good thing. 133FSB is pretty much out of the question. Even 100 is pushing it.

Always cooling first is my rule, so ya, before you up the voltage, make sure you have good cooling and those safety nets.

Good luck man

hey.

Here´s what I do when I overclock my cpu.
First I install Motherboard monitor 5.
I make sure that all the temp-readouts seems to be ok.
Then I graduately overclock, first the fsb with default voltage. At a point I need to increase voltage, then I decrease the fsb a bit at untill it runs stabil (1 hour of quake III and 1 hour of sisoft sandra cpu burn in).Then I increase cpu voltage a bit and increase fsb until it crashes again due to low voltage.
Then I Decrease fsb until it again runs stabil. And then the same procedure again and again until the cpu has reached its max mhz/temp.
The problem is the temp. Before overclocking its a good idea to get a general picture of what temps to be accepted (see oc´s database and/or intel datasheets for your cpu at developer.intel.com) with the different fans.
Furthermore it´s a good idea to remove all non-essential hardware to avoid
boot-up problems and it will make a eventual trouble-shooting easier.
well..that´s how I do it.
Regarding your ram..it´s a question of trial and error with the fsb. Again increase the fsb a bit until it won´t boot and you will have your answer.
Expect the ram to go a bit higher than it´s original specs (pc100 probably will work at 110).
There´s different software to identify ram , the manufacture and id at tweakfiles.com.
happy overclocking :o)

Got a question, now.
My mobo manual _tells_ you how to set jumpers for 66, 100, and 133 FSB speeds.

What I don't get is, how could I choose a number in between 66, 100 or 133? There doesn't seem to be anything for it in my BIOS setup, only the jumpers.

I'm aiming for a 100MHz FSB with 1.1GHz clock speed. If there's some way to get say an 82MHz FSB so I could get 900MHz, That would be much better! =) I don't really want to go as high as 1.1GHz, yet...

you cannot, via the jumpers all are multiples of 33.333 try soft fsb

If your going to use SoftFSB you have to find your clock gen this will help
