Noob question, but how to under/over volt cards?
Do I write eg. 1100 (mV)  or -50 (mV).
Can you give me and example?
Also what value to set? My MSI & sapphire R9 390 show approx.  1100 to 1150 mV on afterburner.

Btw current config:
MSI R9 390 1110/1500, ~290 sol @ 76 deg
Sapphire 390 1100/1500,  ~290 sol @ 78 deg

Is there room for improvment?
Thx, sry for noob question

Claymore keep up the good work mate!
