Do not underclock by setting PL.
+1
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.
how to setting undervolt in msi afterburner?
You have to play with the Power Limit and with the Core... I'm able to mine with lolMiner 96Mhs with 213W... lowering that Mhs start to go down ...
