If you have 1T Dragons with 5 modules with 8 chips per module for a total of 40 chips, then you can slight OC your Dragon.
If you have 1T Dragons with 4 modules with 8 chips per module for a total of 32 chips, do not even think about OC, because they are already OC.
The A1 chip is a very competent chip, it can run in power safe mode, normal mode and turbo mode.
The new 1.4-1.5 T Dragons use more chips and run in power saving mode.
If your 1T Dragon has 32 chip, it can't be OC anymore, there is no room left for that, however you can run them slower to make it more power efficient, you only need to change 2 files in the firmware, but that is not what you want.
Mine only have four boards it seems each doing 255 some a bit less. Can you link me to someone selling one of the new 1.4/1.5's so I can check em out ?
Thx.
