Basic differences between the socket 3 and socket 7 were the number of pins used on the CPU's they supported (socket 7 has more). Socket 7 were also slightly larger.

I believe that on the socket 3's, you are limited to 486 CPU's and possibly some of the first pentiums made, like the 60Mhz.

Socket 7 boards can support Pentium class CPU's (Intel, AMD, Cyrix, etc) up to around 300Mhz. "Super" Socket 7 boards support speeds beyond 300Mhz as well.

Dang, Target you beat me to that answer LOL

Yeah Commod....I'm quick tonight <lol>. Actually, got 11 inches of snow today, and its still coming down. So sitting here at home cause I can't do much of anything else <lmao>..... Just hope my answer was completely correct http://www.sysopt.com/forum/smile.gif

thanks for the help it helped a lot http://www.sysopt.com/forum/smile.gif

Socket 1, 2, 3, 6 -> 486 sockets. 1 is the original, 2 added more pins for Pentium Overdrive, 3 added 3.3V support, and 6 brought more pin definitions for WriteBack caching support and power saving.

Socket 4 -> Pentium 5V (60, 66; 120 and 133 overdrives)

Socket 5 -> original Pentium 3.3V P54C socket, single voltage support only.

Socket 7 -> various improvements, first were more amperage in the definition and a second multiplier jumper for 150 MHz and up, then came split voltage support for P55CMMX, and finally AMD introduced the "Super 7" extensions with a third multiplier jumper, 100 MHz support, still more amperage, and even lower CPU voltages.

Socket 8 -> Pentium Pro

Socket PPGA370 -> 66 MHz Celeron as we know it

Socket FCPGA370 -> pinout, voltage and termination changes plus 100 MHz support for Pentium IIIFCPGA, still Celeron compatible, will also take forthcoming Celeron-III.

Socket A -> AMD Athlon "Spitfire" yet to come.

Peter: Have you ever seen a Socket 6 board? I know that the spec existed, but I've never seen a board that actually shipped with it. It hit sort of late in the game, after Pentium had been released, and the 486 platform was just not that viable as a 'new product' any longer. If there was a system or board that shipped, I'd love to have it. Something of a collector's item. http://www.sysopt.com/forum/wink.gif

I've seen socket 4's up for sale lately but never heard of one before and wondered about them too, as well as the one 800XL mentioned...

[Peter M]

I've personally owned a socket-4 P60 machine. It was an incredibly slow original Intel board with onboard Cirrus Logic graphics that were even worse. I threw that board together with equally bad other stuff, and then gave it to a poor fellow for almost free as a working typewriter replacement ...

Anyway, socket 4 wasn't around for long, as Pentium-75 was socket 5 already.

As for socket-6 boards, I faintly remember a very late Soyo using SiS 496/497 PCI chipset, but I'm not quite sure here.

This is a decent chart regarding sockett/cpu evolution. http://users.erols.com/chare/sockets.htm

[bassboytim]

the fastest chip you can put in a socket 3 is a kingston turbochip or an equivalent. its based on the AMD 5x86 also known as the 486/DX5. it was designed to run at 133 mHz but ive seen it overclocked to 160 mHz with a huge heatsink and some strange soldering.

thanks for the chart, I hard copied it, I have a 486 (in use) with a socket 3 CPU 133 mhz max the board will go. also a board with socket 5 I think only intell cpu will fit in it correct???

Socket 5, electrically, takes:

* Intel's original 3.3V "STD" or 3.5V "VRE" Pentium (75-200, with 150 and up needing two-jumper multiplier setup and stronger voltage regulators)

* AMD's 3.5V K5 series, PR75-100 to stay away from (they are very slow) and PR120-166 being an OK choice.

* Cyrix's original 3.3V or 3.5V 6x86 (up to 150 MHz "PR200"). Some of those use frequencies not achievable on all boards (55, 75 MHz).

* IDT's WinChip series (up to 240 MHz)

Most BIOS from back when these boards were built probably handle the former three fine and well, and most boards will boot through with a WinChip in. WinChips have always been incredibly hard to get, the other two are frequently found in leftover stuff drawers and boxes.

My home surf-O-matic is an old FIC PT-2000 socket 5 board with a Cyrix 6x86-PR166 (133 MHz) on :-)
