Question: what should be buf[6] and buf[7] for 325MHz, 350MHz, and 375MHz?

Ans: This is working on Avalon 2

 case 350:
                        buf[6] = 0xf3;
                        buf[7] = 0x0a;
                        break;

Flash Image from users ckolivas, Xiangfu freq ranges from 300 - 375. Have to edit /etc/init.d/cgminer

Flash Image from user Strombom freq ranges from 300 - 395. Fans seem to run at 100% regardless of temperature.
