I would first try and find out what board you have, so that you can ensure that it will not blow any more processors. There should be a model name and number etched onto it or you can look what "chipset" you have to give you a rough idea of the board's capabilities. Your board's chipset will dictate which CPU's you can run - look for a big slab of silicon next to the CPU socket, look for names like "Intel VX Pro, TX PRo or ALI ALadin V or even Via MVP 3".
But, your board may now be damaged as well as the CPU.CPU Options
As for the CPU itself, you have several options again, dictated by what board you have in there.
The AMD K6-III is a "socket 7" processor, and was not the only one of its type. Intel made the first socket 7 CPU, the Pentium and AMD followed suite with the K6 & K6-2/III. Cyrix also made Socket 7 processors.
Socket 7 speeds go all the way upto 550MHz. But, some early socket 7 processors used a single voltage to operate, whilst some later models like the "Intel MMX" and AMD "K6-2, K6-III", used a dual-voltage and often the voltages involved where too small for older boards to attain.
The K6-III is expensive and rare, however its cut-down brother the K6-2 can be found easily. This is ideally the processor you want, as long as it is dirt-cheap. But the first thing to find out is if your board has gone down.
Socket 7 processor require 2 voltages: I/O and core. older socket 7 processors used a single rail voltage for both the I/O and core, and where called P54c types. Later socket 7 processors used a split-rail voltage, so the I/O and core voltages where different. These later models where called P55c types and keep in mind that some boards weren't very good at supplying the correct core voltage or even enough current to properly sustain correct operation.
P54c CPU's (single voltage):
Intel Pentium, 75 - 200MHz
AMD K6 (early models), 233MHz
P55c CPU's (dual voltage):
Intel Pentium MMX, 166 - 233MHz
AMD K6-2, 233 - 550MHz
AMD K6-2+, 450 - 550MHz *
AMD K6-III, 400 - 500MHz
AMD K6-III+, 400 - 500MHz *
* Rare and expensive!http://www.muszaki-ujszasz.sul...tema...k/cpuelectr.htm
(In the link above, only worry about the Pentium, Pentium MMX and K6-2. The others are old and too slow).Don't Risk Another Blowout
Now, if your board is comaptible with P55c processors, this would be a good CPU to do some testing - a K6-2 300AFR:http://cgi.ebay.com/ws/eBayISA...iewI...ssPageName=WDVW
I had one of these CPU's. They don't draw a lot of power and overclock pretty well. For that kind of money, if it goes down you haven't lost out and if it does work it'll be OK for general purpose stuff.
Hope this helps - some other users may have better suggestions but I would be careful spending too much time and money on that board
