    Question HIS HD3850 IceQ3 Turbo measure points ?

    Finally got around to taking backside photos of my card which has a blue PCB. Any ideas where to measure GPU and Mem volts ?

    Note that only the other of the two points that label "more accurate vMEM reading" is vMEM, the other is ground. Can't tell which is which from the pic.

    To be exact, each GDDR chip has 4 relatively easily accessible measuring points on the backside, each chip has 4 surface mount capacitors that are bigger than the rest. The other pole is always vMEM, the other is ground. So the label "more accurate vMEM reading" applies to all of these 4 capacitor per GDDR chip and all GDDR chips - not just the one cap it points to in the pic.
