Hi, I know it is not a good thing to do overclocking, but i am wondering how bad it is to go around 2% above the recommended max frequency ( 266 to 271 MHz in my case ), this is for a SHARC 21375. I am sure it is not a good practice, but i expect the safety margin to be more than +2% ? What do you think ? Laurent
