The old original 8086 & 8088 topped out at 10Mhz (originally produced at
4.77Mhz). The 80186 & 80188 were the embedded versions of the 808x, but
otherwise pretty close to identical. Well, it looks like the question
has been answered: between 55 & 66Mhz.

up to 66 MHz
"The IA186EB and IA188EB are form, fit, and function compatible with the
original Intel 80C186EB, 80C188EB, 80L186EB, and 80L188EB 16-bit
high-integration embedded processors. Additionally, they have been
upgraded to operate at 5.0V or 3.3V. The Innovasic version operates up
to 66 MHz at 5.0V and up to 55 MHz at 3.3V."
