Hello everyone. I have a question regarding board troubleshooting. Okay so i have an older black A2 terminator 88 and it has 6 boards. 5/6 boards have all 8 green LEDS on. The last board has 7/8 green LEDS on. I believe this 1 led that us not lit, is causing my hashing power to drop about 10 mh/s. What exactly does only having 7/8 LEDS on signify? and how might i go about fixing this problem? Thank you for your time!

Hello i was wondering if i O/Cd my A2 (older black version) to 1280 or 1300mhz if i could do this WITHOUT volt modding my machine?
sorry if this is a silly question.

thank you and i appreciate any responses
