For the uninitiated, make sure to first set your VR to its highest resistance before adjusting it down to the desired level while monitoring the voltage. You do not want to start with the VR set to zero ohms.

Just tried this mod on my card, voltage goes up to 1.365V (stock was 1,33). But it won't go any higher, adjusting the value of the VR has no effect at all. Do you have the same problem or are you able go higher?
