The MMX chips will usually work on Socket 5 boards, but there's a good chance it'll damage the CPU if you run it for very long. The usual solution is just to use one of those plug-in voltage adapters, or one of those upgrade CPUs with a voltage adapter built-in.

Excuse my question, which may sound silly. Socket 5 are commonly called those that don't support dual voltage cpus? The actual socket on the board has written socket 7 on it. I suppose that doesn't change much, right?

Now, the I'm really impressed by the performance of that Cirrus Logic card. I tried also a 5440 one, which was a lot slower(7500kb/s) and in 3dbench it did 110fps. And I found also a 5434 one, which scored 17500kb/s and 139fps in 3dbench. The difference in speed measured in speedsys, seems to affect the 3dbench results the same way. But the 5436 seems to be slightly slower than the S3 trio64/virge cards I've got, and that seems a little weird...

Yeah, the split voltage support was basically the only difference between the two sockets. S7 had one extra pin to allow for that, but everything else was the same. There were some early "Socket 7" boards that didn't actually support the dual voltages, though, which does make things a bit confusing.

Yup, iirc I have an old Octek S7 board that doesn't have split voltage.
Can't remember having ever seena Socket 5 board that does support split voltage.

However, iirc there was also a difference between s7 and s5, their hight was different or something.

This is one reason that WinChip 2 was interesting. It'll run in Socket 5 and 7. The only compatibility problem I've run into is motherboards that have BIOSs that check for and require the "GenuineIntel" CPU string. Evil Intel OEM motherboards.

It also has MMX and 3DNow, but it's not exactly a speed demon. But it's also quite cool running. It should be competitive with Pentium MMX though.

There were btw adapters made. And if you don't want that, theres also the Pentium MMX Overdrive.

I just use a ASUS P5A for all of my Socket 7 adventures and it'll run anything. That's how I did my 133MHz challenge thread. But if I had a Socket 5 board I would probably just use a WinChip 2 since it's in the drawer and it's speedy enough really.

I am intrigued by that chip because it's the only 3DNow-supporting CPU other than AMD's. Centaur designed it to be this tiny little core. It's similar to a 486 in some ways but it performs a lot better. The VIA C3 is pretty much the same CPU too. I also don't think it has compatibility problems like Cyrix stuff.

I agree with you about the Winchip. It's definitely one of the more interesting CPU's. But alas, all my Socket 5 boards are those crappy oem Intel ones -_-

Oh wait, except perhaps that Octek Socket 7 monorail board. It's HX too 😀
