Hey fella I know I sent you hear from YouTube but I did say read the threads. 200x20 right.... what about everything else youve set, it will be a setting or volts you have not done right.

Theres a bucket load of threads helping people get to 200 BCLK and Im really sorry but Im not writing it all out again.

Please look them up first and read all the thread, then come back with some very specific questions
