All my card are stock, no mods.

Hmm, it seems I have slower Nano card, I see only 370H/s instead of 393H/s. Can you please share your Nano card details? Manufacturer, model.

I have 7 R9 Nano; 6 Sapphire and 1 ASUS.

Is your card thermal throttling the clock speed due to high temperature?
Those R9 Nanos can get pretty hot, I have 4 extra fans blowing on them.
