Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_15261_1 ( voltage_range__v_ VARCHAR, clock_multiplier VARCHAR, part_number VARCHAR )

### Question ###
What is the voltage range (v) if the clock multiplier is 3x or 2x mode and part number is a80486dx4wb-100?

### Accurate SQL ###

SELECT COUNT(voltage_range__v_) FROM table_15261_1 WHERE clock_multiplier = "3X or 2X mode" AND part_number = "A80486DX4WB-100"
