ATI 3850/3870 Voltmod thread

[Jimbo Mahoney]

Is there OCP mod required for these cards? I did vmod and it works fine but when I raise voltage to say 1.5v I cant run 3dmark even at stock clocks. It goes black screen. 1.4ish volts works fine.

Not normally. People have been running 1.9v without problems.

EDIT - hehe actually my Triplex 3850 does have OVP or OCP - I can't go above 1.55v without it shutting down.
