What is the voltage range (v) if the clock multiplier is 3x or 2x mode and part number is a80486dx4wb-100?
create table table_15261_1 (voltage_range__v_ varchar, clock_multiplier varchar, part_number varchar, PRIMARY KEY (voltage_range__v_))
select count(voltage_range__v_) from table_15261_1 where clock_multiplier = "3x or 2x mode" and part_number = "a80486dx4wb-100"
