  Still a couple left as of this post.

This puppy will be going into my 486 gaming DOS PC.  Should be quite the boost form my 66MHz DX2 to a 100MHz DX4.

Does your motherboard have an "overdrive" socket?

I thought these chips required this socket.

These are drop-in replacement upgrades for any socketed 486 CPU. The Overdrive versions include an onboard 3.3V regulator to support machines that only have 5V CPU sockets.

Maybe I should have done more research.  I thought the point of the overdrive was that it had a voltage regulator.

Hah, ninjaed by NJRoadfan.   Glad I wasn't wrong.

I do have a motherboard that supports both 3v and 5v chips, but I'm not using that one.  So if that were the case, I could've swapped out motherboards.  But I like the one I have now because of the orientation of the ISA and VESA slots.   I also like the aesthetics of my current board with the 30-pin SIMMs and the little individual cache chips that I put in.  The other one has 72-pin RAM and the cache is soldered.

Edit:  I did learn the hard way about 3v versus 5v.  I used to have an AMD DX4 in the other motherboard, but when I switched over to my current board it's 5v only.  So I burnt out my DX4.   That's why I wanted the Overdrive.
