Standart quartz oscillator

[Altera_Forum]

i connect standart oscillator ALTUFM_OSC osc( .oscena(1'b1), .osc(clk)) 

i count 6 000 000 by counter.   begin counter = counter+ 1'b1; if(counter == const_data) begin signal = ~signal; counter = 25'b0; end  LED blinks once per second. Is it means, that frequency of quartz oscillator is 6MHz (instead of 50MHz)?
