So copy the 1500 strap into all the higher straps




0:1625 7770000.....
0:1750 7770000......
0:1875 9990000......
0:2000 9990000......


If I copy these timings correctly  am I unlikely to cause a bricking if I have chosen the wrong combination ? If a combination works but it isn't the fastest its simply a matter of testing it and then reflashing the BIOS? eg copying from 1500 up or 1625 up is no more likely to cause a bricking? Or is 1500 up considered more aggressive than 1750 up?
