Currently Intel is the only manufacturer selling 5v 486 chips. It *should* be a straight drop-in, no jumper changes required.
A *very* old motherboard *could* have a problem supplying enough current for the doubled chip. But I haven't seen that happen yet, and I've upgraded a number of machines. There might be a problem with the motherboard going from SX to DX, depending on the chipset on the motherboard. But, again, unlikely. For the <$40 these chips are going for it's worth trying. Cyrix and AMD make 486DX2s but they are 3 volt. This would require changing motherboard jumpers, if your motherboard supports 3v chips. Either way, if you're going to max out an old box you might want to do it reasonably soon; 486 pinout chips and 30 pin SIMMs will soon be history.
