Intel Pentium MMX 166

Same as this Pentium MMX 166 except that this version comes with an attached heatsink/fan solution. I also noticed that this CPU is multiplier unlocked so it can easily be set on 200MHz by raising the multiplier to 3x. Mutliplier locks prevent people from relabeling a CPU to a faster model. For example: take a Pentium MMX 166 and label it as Pentium MMX 200: the one who buys it, at the price of a MMX200, configures it at 200MHz and actually over clocks his/her chip. This can cause instability and Intel loses sales. As far as I know Intel began with the multiplier locks on some of the Pentium 133 CPU's but didn't lock all CPU's at once so there are newer unlocked models available.
