After an aborted attempt of building a socket 7 K6 III+ system (CPU correctly detected but the system keep rebooting instead of booting the OS) I've decided to try VIA C3 as it looks like it gives me even more flexibility. I've found a suitable mobo with 3 ISA slots and I have a few CPUs on the way, an Ezra 800 Mhz, Ezra-T 1 Ghz and a Nehemiah 1.2 GHz. Would I be right in saying the Ezra-t would be the one to go for for the greatest flexibility at the lower end of performance? Also is the multiplier locked to it's rated speed (i.e.133 x 7.5) or can I attempt to go higher (i.e. overclock). Presuming the multiplier isn't locked, With I cache disabled is it likely to overclock more than if all caches enabled (i.e. full speed) and give me more working multiplier options?
Also I'm I right in saying the main benefit of Ezra-t vs a regular Ezra is that the FSB isn't locked?
Keen to hear how you go with all of this. What motherboard did you end up going for?
I had the same problem as Ivader on my Intel 430TX chipset Asus TX97-X motherboard with K6-III+ 500 running at 6x83 with a patched 0112X_J2 BIOS from The Unofficial AMD K6-2/3+ Page. I haven't seen this issue and (simple, but not obvious) solution documented anywhere so it seemed worthwhile to comment on when I saw Ivader's post from many years ago.
Like Ivader said, the problem was: "CPU correctly detected but the system keep rebooting instead of booting the OS". The issue ended up being that my computer wouldn't boot with a K6-III+ and incompatible USB keyboard. If I switched to a Pentium MMX 233 with the same USB keyboard then the problem went away. Additionally, if I kept the K6-III+ and switched keyboards then the problem went away.
The final solution for me was to switch keyboards. I was initially using a Logitech USB keyboard that was apparently incompatible and switching to a Corsair USB keyboard solved the problem with the system continually rebooting. I eventually switched to a Filco USB & PS/2 keyboard that worked even better for my situation by allowing me to use PS/2 on retro systems and USB on my newer systems that support USB at boot.
