Adventures in OC'ing a Celery 433

I've been able to OC my Celeron 433 to 540 (83 bus).
Unfortunately, when I try to go up to 585 (90 bus) the system POSTs OK but freezes when starting to boot to Win2k. I can get to the boot up menu, but after I make a selection there's a little bit of HD activity (1 second) and everything freezes.
Is this a cooling problem? (I'm using the stock Intel heatsink & fan on a MSI 6163Pro MB)
Or is there something else I should look into?

Thanks.

 
Be happy with the o/c you have now. I had a cel 433 and could only get it to 488!! The 433 isn't the best celeron to overclock, but i'd say your overclock it great for that chip.
 
If you REALLY want to try to get it to go faster, you should lap the core and get a good heatsink. The only problem is, that you are only going to get so much out of the Katmai core... you're at the point where you are going to be throwing dollars at it to get pennies worth of power. The better way to go would be to save your money and get a P3e or a CeleronII... you could then get a few hundred MHz more rather than just a few MHz.

But would cooling help to get it "over the hump" to 585 (90 bus).......it just seems like a small step to go from 83 to 90 FSB....and it would let me rest at ease at night knowing my PCI cards are running at a steady 30 instead of 41 😀
 
It's possible. I managed to get my 466@600 with a slot1 Alpha. Only prob was my PCI speed...way too high..so I made a watercooler, bought a few 90W TECs and ran it at 733 instead. Much better😉

ThreeDollarBill,

As you can see from Duckie's example, things are doable if you are willing to spend the money. There is no guarentee that your specific chip would make it to 585. Some will, some won't. The only way to tell is to try.

Since you are only dealing with a retail heatsink, perhaps you should give some serious consideration to lapping the CPU (do you know about lapping?) and getting a better heatsink/fan.

You also haven't mentioned whether you have a S370 on a Slotket or a Slot1 style CPU. Nor have you told us what core voltage(s) you've tried. If you have a S370 type CPU, I would suggest getting one of the new Alpha PAL3065's (you can pick one up at Plycon) since these work on Intel or AMD Sockets (and a Slotket if you have one). That way, if you decided to move up to a newer chip you, whichever brand, you have a nice HSF to go with it.

It all depends. Let us know about your voltage. Also, I serious about lapping. I had a couple of Celeron's that wouldn't do 550 stable but did 583 stably afterward.

Hmm someone said he had a katmai core the first celerons(I mean celeron a) where mendocino cores not katmai(first gen p3)

Here are the specifics:
Celeron 433 (S370) on a Slotket.
MSI 6163Pro Motherboard

I tried all combinations of core voltages and even chipset voltages at the 90 FSB, no luck.

And could you tell me what lapping is? I believe it involves sanding the CPU???

Thanks for the input.
 
Celerons 300A-500 (& early 533's) were the Mendocino.
Celeron 366's & up seem to have a limit of around the 550MHz area with air cooling

Right you are... wasn't paying attention, my bad.
