I wanted to know how to speed up a Beige G3 and a B&W G3 processor. I know there is a DIP switch thing under the void warranty label that says speed control. How would I set it up so that it would go faster? If you have the information please tell me. Thank you.

Google's your friend. Look up beige g3 jumper settings.
This was the first result from a google search with "beige g3 jumper settings".
http://www.wmld.com/tech/jumperchart2.html
It's not difficult to do - I had a 400 mhz beige g3 a while back (overclocked with a 350 mhz chip from a B&W)
Every time I try to speed it up past 450 Mhz. I get a kernel panic message. I'm running OS 10.4 I have 768 MB of RAM. I don't know why it's doing that, does it have to do something with the motherboard or processor model?
Providing you're doing everything correctly, your processor may simply not be able to clock above 450 MHz.
Consider the jumper settings at the link above as what you can set the board to, but not necessarily speeds you'll be able to reach. Every processor is different, and some overclock better than others...even from the same manufacturing batch.
You might have better luck trying for 466 MHz with a 66 MHz bus, though. I never had stability when messing with the bus speed on the beige G3.
I really don't understand what you mean by "bus". And I don't understand how 66mhz can be multiplied by the numbers given to get 466? Help please.
First, what speed chip are you working with (in native form)? Second, is this the same computer as the one you are describing in http://www.applefritter.com/node/21464 ?
The numbers will be a little weird - just work with the numbers on that page given, or just come to terms with the fact that you're getting 450 mhz out of a beige.
If you look at the chart on iantm's link, you'll see that to get your processor MHz, you're setting both a bus speed (pins 5, 6) and a multiplier (pins 1,2,3,4). Bus speed x multiplier = CPU speed.
In simple and perhaps slightly inaccurate terms, the bus speed is the speed at which the logic board runs. Or how the CPU relates to the rest of the system. PCI, memory, run based on this setting.
In order to get your 450 MHz, following the chart you'd have set a 75MHz bus and a 6X multiplier. That's not desirable, because a 66 MHz bus is likely the only way you're going to achieve lasting stability.
For 466 MHz with a 66MHz bus (and to clear up your confusion if you were doing the math it's really 66.66 MHz) You'd be setting a multiplier of 7.
What is the original speed of the CPU? This might be debated, but you could consider a 25% overclock to be a rough ballpark expectation and move up or down from there.
i have my Beige G3 running at 466mhz i used a B&W G3 450mhz cpu. i am not real fond of OCing a cpu so a 16mhz oc wont hurt much if at all. but taking huge jumps in trying to OC a CPU will almost result in not booting or the OS crashing.
i have another AIO with the stock 266mhz cpu in it it would only OC to 300mhz cause if i went farther it would not boot. not all (even the same CPU at the same speed ) will OC good or not each have there head room limits. heat is a major issue when OC any CPU. plus if the circuitry can handle the extra stress of the OC.
if you over push that limit the CPU might work but it will eventualy burn out and have a dead CPU. even with good cooling. you can tell when it happens cause everything will get real unstable and crash allot, or it just will not boot (even if you take the speed back to stock settings)
