I have a Pentium 100MHz and am wondering if it would work to repalce it with an AMD K6-2 550MHz? I dont know what form facter the motherboard is (If it helps any, its from (well still in...) a Compaq Presario 9546, and I checked Compaq's website and they didnt have much technical info on this model), it's Socket 7 (NOT Super Socket 7) and it has a 66MHz FBS speed, mutlipliers of 1, 1.5, 2, 2.5, and 3, with 4 72-pin SIMMs. Im not real sure the voltage settings, and the board is of unknown brand. I havent realy been able to get a straight answer about this, some people talk like it could work whiel others talk like it wouldnt. (Please dont just sugest getting a new MoBo...)
Thanx!

i recently tried putting a 400MHz AMD k6-2 in my socket 7 MB from 1997 and it wouldnt accept it, keept complaining that it cant determine the clock speed

In a few words: You're joking, right?

If you put your k6-2 in there, you would kill the processor because a k6-2 uses significantly less voltage than a 100Mhz pentium. There is no way it would function in your board. You _might_ be able to use a regular k6 (if you can use MMX processors the chances of it working are greater). Then again, a 100Mhz pentium board is ancient, so it would be safe to say that a k6 wouldn't work in there.

many motherboards you can select the operating voltage of the processor (on my ancient pre pentium 2 you can) either 3.3v or 3.6 volts. the default is 3.6, but a k6-2 uses 3.3v with a 2.2v core.

You have to run the k6-2 at it's core voltage...(trust me, my k6-2 is running at 2.2v right now..and has been for a long time). So older boards will just kill the k6-2.

There are modules (or whatever I should call it) which you put between the processor and the MB. These have a voltage regulator to provide the lower voltage.

yeah, my MB has core voltage settings of 3v or 2.7v, both of which are way too high. Anyone know what voltage a cyrix 333MHz runs at?

Cyrix processors are 3.something. They are very power hungry and run really hot (don't just strap the heatsink on...you have to use thermal mount..and make sure to get a BIG heatsink).

Arent Cyrix made by IBM? Do they still make them? Fastest one Iv seen was 866MHz, so maybe they dont make them any more?

Wow, you would think you computer geeks would take some pride in your systems. NO you cannot shove an AMD into an Intel socket. Mhz is based on FSB x Multiplier, if your FSB is only 66mhz you would have to be able to increase the multiplier to like 9, which you would definately not be able to do with that board. Even if the processor fit and you were able to reduce the voltage so it didn't kill it, you would have to know how to unlock it so you could run it underclocked (because like I said you will not be able to attain a 9x multiplier, and in order to change the multiplier you would have to unlock it)

Um, The k6, k6-2, and k6-3D are all socket 7...so yes, you can fit AMD processors into "Intel" sockets. Up to the k7 (athlon) all of the AMD's processors did that.

Just because it is the same form factor doesn't mean it will work. It won't work

Yes it will if your board has the right voltages. My old board from 1997 suported voltages for the pentium/MMX, Cyrix, and AMD K6 processors. My 1999 GA-5AX works fine with AMD k6-2 processors (in fact they are the best to use with it...). It can do bus speeds from 66 to 140Mhz too. In FatalDragon's old board, a k6-2 won't work. But in most boards made for the MMX Pentiums, a k6 should at least work.
