1300mhz is fine, it should drop your core voltage all the way to 0.718V and drop your power consumption all the way down to 60-70%. Are you still getting PWR in perfcap with voltage at 0.718V?
Yup getting pwr soon as i OC above 250-300 mem .
thats really odd. does gpu-z display the breakdown of your power consumption e.g gpu chip and mvddc power draw?
@Geck
Do not underclock by setting PL.

In windows only use the Afterburner to set a fixed voltage.
Lowest i could get is 0.737 or so. If anybody finds a solution to go lower..... post it.
My zotac 3080 goes to 718mV, but i'm not sure if this is the case for all 3080 - my other rtx cards have different minimum voltages.
FWIW i use awesomeminer to set the voltage. If it goes too low, the memory will drop to 5000mhz.
