Are these compatible?

[Hokosaki]

I'm looking at a motherboard on ebay that has a DX4 processor. Would a DX2 processor work on that board?

found this on Wikipedia: "The IntelDX4 microprocessor is mostly pin-compatible with the 80486, but requires a lower 3.3V supply. Normal 80486 and DX2 processors use a 5V supply; plugging a DX4 into an unmodified socket will destroy it. Motherboards lacking support for the 3.3V CPUs can sometimes make use of them using a voltage regulator (VRM) that fits between the socket and the CPU."

Going from a DX4 to a DX2 is usually possible, but depends on the board itself. If it's possible via jumpers to switch CPU voltages, it will work.

There are 3.3V DX2 as well if you're too lazy to change the jumpers.

Thx for that info
