No, both versions of the K6-3 have the same amount of cache and performs the same. The difference is that the AMD K6-3+ is developed for laptop computers and run at a lower voltage, making them more cooler and easier to overclock. The AMD K6-3 for desktops runs at either 2.2 or 2.4V, but is generally much more compatible with motherboards. For instance if you have a board with only 66mhz FSB or 83mhz FSB, then its almost guaranteed to not run with the + models, while the regular AMD K6-III will.

k6-2: 0.25um process, no l2 cache
k6-3: 0.25um, 256k l2 cache
k6-3+: 0.18um, 256k l2 cache, only for mobile and embedded
k6-2+: 0.18um, 128k l2 cache, only for mobile and embedded
no doubt the k6-2+ and k6-3+ are better at overclocking, but they usually don't go much higher than 600mhz due to their pipeline design. and they also have a lower absolute core voltage(that will cause damage) at 2.2v.

Over clocking is not my thing when it comes to 15 year old hardware.
It will stress old stuff that might break.

Some Super 7 motherboards support the required voltage for the K6-2+ and III+, so you can use them in desktop systems, too.

A lot of boards do suport de ''+'' cpu, just look at the k6plus website from steunebrink. He made lot's of compatible bioses for these cpu's.

The regular k6-3 is a hothead, so use good cooling for that one.

of course i know they would run, i meant that amd didn't release them for desktop purpose.

Of course it runs in desktop mobo:
AMD K6/2+-575

Here's running @5,5x100 (original 6x95)

Your Fic board supports the K6-2+ You need one of the later bios's

Thats what I had in mine a K6-2+500 100fsb, till I put it back in storage.
Its basically a lower voltage K6-3 with half the L2 cache.
My other fic board required me to disable the onboard L2 to get it to work stable.

Mine ga-5ax works with onboard cache enabled without any problems.

He has the same fic board I do PA-2013.
There finicky beasts that are defective in more then a few ways.

Today my 97yr pc300gl type 6282 refused booting, stopping at post step 69, replacing "coast cache module" solved the problem.
coincidence?... hard truth.
