In the higher Athlons, the C in the CPU code -- like AMD Athlon 1400AMS3C -- means 266 Mhz Bus capable.
Can these CPUs be run at 200 MHz bus? I have conflicting reports. 50% say they can, 50% say they cannot, they have to be run at 266, they will not work on a motherboard that will only take 200 MHz CPUs. Anyone with any direct experience running the 266 Athlon on MBs that can only take 200 Mhz?
