How to change voltages for GPU oc'ing

Go to solution Solved by Face2Face,

Sadly at stock voltage my card can't handle more than a few seconds at those speeds :(

 

 

I can ad 75mV to the card

 

Okay good. You can safely add +75mv to your card without hurting it. If the card gets too hot, it will automatically throttle or create a fan profile so it doesn't.

     Im using an ASUS 780 ti directcu ii and MSI Afterburner. I unlocked the voltage control but I have never used it for oc'ing and am wondering how to utilize it without melting my card. I'v played around with 5mV changes but they don't show up in HWMonitor or Afterburner. Are the changes too small to be detected?  Another thing I was wondering was what the safe voltages are for a 24/7 oc and for benchmarking.

Just drag the wattage limit to 107% and put 130/200

130Mhz in core and 200 on memory

=

success

Emmh... Maybe consider killing yourself before you talk to me?

 

Pople on this forum though some of them had a brain, turns out, no.

How much can you add when unlocking voltage control? How many mv?

lol I added the 75mV and it oc'ed its self higher than what I had it at xD. 

I thought the voltage stuff was going to be more like a CPU.

I hope with this voltage bump I can get to those speeds

With a DCUII card most of the time you can safely max out the power limit and core voltage because the cooler will always keep it below 70C

Then just overclock as much as possible :)

I'm having trouble making the gpu run at the new voltage. When I first applied the new voltage it would run but now it just applies the core and mem oc and leaves the voltage at stock. Iv tried restarting the program and my comp. ant ideas?
