HM6343 change update rate

I have been using the following arduino code to try to change the compass module update rate between
1,5 and 10 hz
I modify the 4 line as follows
0x02 for 10Hz
0x01 for 5 hz
0x00 doe 1 hz

however I can not see any change in the speed of the serial.print speed nor any additional values

do I need to do something else????????

Thanks in advance

Wire.beginTransmission(HMC6343_ADDRESS);
Wire.write(0xF1);
Wire.write(0x05); // EEPROM address of Operational Mode Register 2
Wire.write(0x02); // (OM2_1 = 1 && OM2_0 = 0) == 10Hz operation
Wire.endTransmission();

do I need to do something else?

Please post the whole sketch in code tags. We can't see if the way that you print has an effect on how fast printing takes place.

After reading your response I noticed there was a fixed delay in the loop that was impacting the changes I was making to the register.
Now fixed
Many thanks
