Processor speed for older computer?

Question

I refurbish old computers. On a Compaq 5286 the processor speed is determined by a jumper setting. The highest setting is 500mghz. I have installed a Pentium 3 rated at 547mghz. If I set the jumper for the 500 mghz setting, will it be limited to that speed or will it run flat out? If I leave the jumpers out all together, will that enable the processor to run at its max rated speed? 
  Over clocking is out of the question due to the ancient bios which has no processor settings at all. Any help would be greatly appreciated.

I have been upgrading old machines for years, and have found that the adapters sold by PowerLeap can often give you vast improvements in processor speed and choice.

There is both a manual and automatic method of determining what adapter will work in your machine, and what the limits of processor speeds are.  Go to the PowerLeap site to run them.

Unfortunately, their servers are down as I right this, so I can not see what the adapter for this model is capable of.  But I have used their adapters on quite a few old machines, going from 200 - 400MHz processors, to as high as a 1.4GHz processor in one machine.   The adapters add additional clock multipliers to your socket, as well as voltage regulators for the newer, lower voltage processors, not made when the motherboard was designed.  Then also have a bios program that works with the native bios for some adapters, that allow the faster processors to boot up properly.   

I have had a couple of machines that there were no adapters for, but none in which an adapter failed to perform as expected.
