Hello,
I've an easy question for you (not for me).
Is it better a Cyrix Mii 300GP 66MHz bus or 75 one? I would like to buy one.
My motherboard seems support both.
Regards,
S.

MII 300 3x75 = 225 MHz
MII 300 3,5x66 = 231 MHz
so 66 MHz variant is faster in theory. In practise most tasks in system will benefit from higher FSB or will be the same Smile

13% higher Bus should for most things that need any access to RAM etc be fast then a 3% boost in clock

Finally I got a Cyrix Mii 300GP 66MHz.
I think I can switch from 66 to 75 MHz (and lowering the multiplier too) without any problem.
Cyrix Mii are poorly overclockable as I suppose, but I'm interessed on nice ALU performance and branch prediction capability.
