I'm talking about the Original K6 and the "Little Foot" revision. Did the first release 166-233MHz cpus have no trouble fitting in typical socket 7 motherboards? (Intel 430 series chipsets) and did the K6 233 work in the same way as the Pentium MMX 233 where you set the mobo to 1.5x, then the cpu set itself to 3.5x internally? Are the 266 and 300MHz Little Foots configured the same way? I don't think any 430 chipset mobo could be set past 3X without using the PMMX trick. Was it more common to use faster K6's with non-Intel chipset mobos?

I was reading that the BIOS had to be updated prior to installing a K6, and the K6 300 was slower than a Pentium II 300. Was the K6 300 the same speed as a Pentium II 266 then?

"The K6-2 (400 and up) was a big success because it was a good upgrade solution for owners of Pentium MMX platforms—by using the 2X multiplier on a motherboard with a 66 MHz bus, the processor was in fact operating at 6X (400 MHz), which permitted a significant gain in speed at a lower upgrade cost."

More info on this quote?

I remember I had a k6 233 that I was able to drop into almost any socket 7 system without changing any settings and it worked. This was when I was 15 and didn't know much about computers too but I new the k6 worked in anything.

It really wasn't any different in terms of speed, I'm not sure why I favored it.

What info on the quote? It is true that K6-2/-3 interpret the 2x setting as 6x. Useful when your MB only has 2 multiplier jumpers/switches (BF0 and BF1).
The 1.5x setting is used for 3.5x, for both K6 and K6-2.
K6 should work in most socket 7 MBs. It uses a bit more power so the voltage regulator could give trouble if it doesn't have enough headroom.
The chipset itself isn't a problem. A K6-2 will run in an Asus P55T2P4 (430HX). The MB just has to supply the right voltage (no problem with a K6 when the MB supports P1 MMX) and BIOS support.

K6 (Model 6)
VCore: 2.9v for 166 & 200 MHz
VCore: 3.2v for the 233 MHz
V-IO Min/Recommended/Max = 3.135v / 3.3v / 3.6v
.
K6 "Little Foot" (Model 7)
VCore: 2.2v for all (200, 233, 266, 300 MHz)
V-IO Min/Recommended/Max = 3.135v / 3.3v / 3.6v
.
I also had a K6-233 on a TX chipset back in the day.
It was favored at the time because it had MMX and cost a butt-ton less than the Intel 233 MMX.

What I meant was: What are the settings for other K6 speeds? If 400mhz K6-2 is 2x mobo, 6x translated, what about for a k6-2 333 for a 66mhz Socket 7 board? Any info on other speeds? I was thinking on trying a 333 for an upgraded Win95 machine plan.

Iirc K6 didn't translate 2x to 6x, but I could be wrong. I do know the 2x multi was changed around that time though I don't remember when exactly this happened. I think it was with some new core revision.

What you are asking is motherboard dependent and you should look in your manual at the tables like these.

That's from a manual for a 430TX board.
Hope that helps.

I believe it was changed with the K6-2 CXT (K6-2 stepping 12). The regular Chomper chip obeyed 2x multi.

I don't think any K6 (not K6-2) model has a 6x multiplier. Even the fastest 0.25µm Little Foot is only meant for 300 MHz, so a 6x multiplier (400 MHz) would be quite an overclock.
