Trifecta,
My Matsonic booted very easily at 2.0V 5.5X - first try..
It also ran for 24 hours at 2.1v 6x (use the 2x setting it maps to 6x). It began to crash on IE so I went back to 2.0V 5.5X. I never tried 2.2V
The board will only post to 550 but testing does show 600. My BIOS is dated 7/95 if you find a more recent version pls let me know.
I have some 128m PC133 memory on order so I would like to try a faster bus speed but as you said this board won't support it. I'm going to try 600 mhz again when I install the new memory. Currently I have 64m PC100.
I also have an Epox MVP3c. It's similar to the Matsonic in performance, but I haven't tried the K6-3 in it. (ANyone think I should?). You could buy a new board but for the investment why not move to the next generation technology? I'm just trying to squeze a little more life out of SS7.
CPU Mark was 55 at 600 and 50 at 550
ps According to SiSoft I went from 825MIPS, 471 MFLOPS with my K6-2 350 (@400) to 1451MIPS, 737MFLOPS with the new chip (@600).
My video card is an ATi Rage 8m.
You can look at my results including video at

Good luck, let me know how you make out.
