Attempting to redo my overclock for my 780 and 2x now the voltage dropped causing Valley to freeze up.  Didn't crash but might as well have.  
 
Once it dipped to 1.000 is when it happened.  Second dip is seen on the gpu voltage at same point at second freeze/lockup.  Thoughts?

    Does it happen at stock clocks & volts? If it does it's most like a driver issue.

    Nope.  Ran valley for 30min just to be sure was stable and no issue.  Then I started cranking up the gpu offset.  @+55 when I started to see it.  Rebooted each time I saw it freeze/lockup.  So I started throwing 5mv increments to 20mv and no change.  Even tried going up on gpu offset up to +65 and did same thing.  If I drop to +50, no issue on stock voltage.  Again 30 run on Valley to test "stable".

    Voltage increments in steps of ~12/13 mv. So changing it 5mv up or down, does nothing until you hit the next voltage increment.  The same with core clocks you cannot adjust them one Mhz at a time regardless of what the slider says. For example if your GPU is running at 1032Mhz, the next step is 1045Mhz. There is no in-between.

    If you were using PrecsionX (4.2.1) you could enable K-boost, voltage will never drop(nor will the core clock).
    I still cant believe people don't know about K-boost( FYI MSI AB does not have this ability).

    FYI, MSI Afterburner does have this ability...

    Can't.  Out of warranty.  Was a bstock gpu that expired on 2/2015.  So I'm screwed for the time being till I can save up for another gpu.

    Dude, that sucks.  Do you at least have a spare you can use?

    Nope.  I mean the hdmi ports work for now.  But I'm not sure how long that will last either.  ASIC quality is in the 60's and can't OC it for crap.  I know now why it was a bstock item.  Its a garbage card in my eyes.  My old GTX 260 ran better.  lol
