Thanks, it work fine,
but i get only  6.253394 MH/s  Sad

My  FPGA is Virtex IIPro XC2VP50 and project settings are:
  miner clock frequency = 50 MHz
  DEPTH = 3

In your opinion, is  6 MH/s correct value for this project settings?
or did I do something wrong?


DEPTH = 3 means 2^3 = 8 pipeline stages for the 64 SHA256 rounds, so each nonce will take 64 / 8 = 8 clock cycles. At 50 MHz that's 50 / 8 = 6.25 MH/s.
