AMD K6-2 475MHZ

Whats the problem EXACTLY?

I presume you mean it won't boot at all but you need to be more specific. I can think of a couple of things it might be....

I assume you mean it won't run at all. If that's the case, you need to update your bios if you have your jumpers set right.

If you have win95B or later you'll need a patch for your OS from Microsoft.

I would double check that the mfg has not changed the recomended jumper settings.

Also, the 233 ran at a buss speed of 66MHz.
The 475 runs at 95MHz (I think).
Is your memory either EDO or PC66?
If so, you may be over-clocking your memory, and it cannot take it.

To check this, set the buss speed back to 66MHz, and see if the system now works.

If it does, you have 2 choices;
Underclock the 475
Purchase new memory.
If you purchase new memory, make sure it is compatible with your MB. Not all older mbs work with the newer DIMMs.

Check the board to see what year the board was manufactured
AMD K6-2 fits all socket 7 interface,but one of the requirements is that the motherboard must support a core voltage of 2.0 or a max 2.1
Older boards built in 1996 and 1997 that are basedon Intel's 430HX,TX,and VX chipset voltage controller offers a minimum voltage of 2.2
The other part is that the K6-2 is limited to 66X6=400 MHZ,so the bus speed needs to be overclocked to achieve the clock frequency multiplier to operate cpu at 475Mhz
Good Luck

I have four workstations with various k6-2 processors. I found that DFI makes motherboards that really make them perform well. You should still be able to find them. They are cheap and easy to set up.
