Hello,
I've been running a ML2 for about 2 days, pretty much at stock settings (upped freq to 620) on a macbook pro usb3 port.
It has been running stable for that time, but suddenly the hashrate dropped to 2.1 - 2.5 MH, it used to be stable at 3 - 3.2 MH.
Am I missing something right here? My setup didn't change (no other devices attached).
For stable 3 MH you will need more than 500 mA. Can macbook pro usb port suplly current more than that?
I have no idea, I can only tell what I saw these last 2 days.
This is what system info says
Current Available (mA): 500
Current Required (mA): 100
Extra Operating Current (mA): 0
Apple docs:
Apple computers equipped with USB 3 provide up to 900 mA (milliamps) at 5 V (Volts) to most Apple USB peripherals as well as all third-party USB peripherals that comply with USB specifications.
