That's may not be true!!!  My friend had a 6x86 P166+.  and it works like a
charm!!!
Not a single problems at all!!!

Firstly, apparently, 6x86 chips only works perfectly with certain
motherboards.  All first Triton chipset boards works, Some of Triton II,
and Most of Triton III.  I would recommend Triton I chipset motherboard to
work with 6x86 chip.

Second, there are problems with misleading of information of configuration
settings to the 6x86 CPUs.  Especially the Intel introduced this so called
"Downgrade" P-rating standards.  Which means that the 6x86 P166+ is not
6x86-166Mhz.  Is much lower performance, but with the speed of Pentium 166.

Thirdly, motherboards in the market have some incompatibility problems. 
Even with a true Intel Pentium CPUs.  Mainly because of compatibility with
components that said by the manufacturer that is Triton series compatible. 
So if considering getting a motherboard, besure it has a well brand name
with a good reputation!!!

Thirdly, the fan, a good design fan will work well, although is pretty
bulky and pricey, but it works!!!  And also a heat transfer compound gel
will help to assist transfer heat between the CPU and the fans heatsink
quicker.

Finally, I do have a 6x86-100 (6x86-P120+), and I don't have any problems
with it.

I don't argue with anyone, is just my friends gets there 6x86 working
right!!!
