talk to @Agent-A01. He's convinced he has the commands that will lead to an unlocked 780Ti. I would love to see if it's legit or not.

I will be mounting some EK blocks on them this month with 3 280x144 rads i one loop.

I need all details you know on the mod.

I've looked at this post down the thread with this pic.
http://www.overclock.net/content/type/61/id/1850457/width/500/height/1000/flags/LL

100Ohm will give about 1.5v he said. What if i wanted 1.3v - 1.35v.
Do you have the numbers for what Ohm i need.

And, When the resistor is there. Is it possible to adjust voltage by BIOS or is it a permanent 1.5v with 100Ohm?

Also what kind of resistor should i use. There is a bunch of them types.
https://www.elfa.se/elfa3~se_sv/elfa/init.do?toc=19414&name=Motst%C3%A5nd+%2F+Potentiometrar

http://www.overclock.net/content/type/61/id/1850457/width/500/height/1000/flags/LL
www.overclock.net

And a last thing. The voltage and clocks steps down when the cards not under load standard. Would that be possible with this mod?

Sry it's many questions at once. I really need this info. Dont want to fry them babys.tongue.gif

100 ohm will give you 1.5v
so

1.212v + 100 ohm 0.288mV = = 1.5v
1.212v + 50 ohm 0.144mV = = 1.35v
1.212v + 25 ohm 0.072mV = = 1.28v

if you can get DIP switch

you can add 3 or 4 resistor and control it like any software by using the key to enable and disable it.

tell me what the number it returns is.

Make sure you are in the msi ab directory. Must be using one of the later betas of msi afterburner.

Thanks

Device manager says the second 780 Ti has been shut down due to it not working correctly. I have tried replacing the sli bridge, using DDU to uninstall the drivers. do a clean install of 2 separate drivers but nothing. I then disconnected the PCI-E cables to the second card (while it was shut down of course) and the system continued to work without a hitch except that the device manager no longer recognized the second card- as it should.

GPU-z saw both cards but not the VRM temps of the second (that lower half of the sensors tab was missing) and all indicator LEDs for BIOS and voltage were ok.

I had that error when testing our modded alpha bios! A re flash always fixed it!

I am also wondering if nvflash will even detect the second GPU since it has been stopped by Windows and precision x can't even see it anymore.

Quoting all 3 posts in case someone else has a solution. I was unable to flash again since nvflash did not detect the second card at all (Windows has disabled it). I switch to Normal BIOS, both GPUs turn to green LED as usual, GPU-Z reads the change in both cards but says second card is at PCI-E 8x 1.1 even on the render test. Anyone else have any solution? Cheers!

Maybe you could try this:
  1. Shutdown pc remove the PSU power cable
  2. Remove both 8pin cable from GPU
  3. Press power button in the rig to discharge the PSU and the rest of power in the circuit board
  4. Wait about a minute ( two minutes recommended )
  5. Plug back the PSU power cable
  6. Do not plug back the twi 8pin power cable to GPU.
  7. Turn on PC boot into UEFI or Bios and enable IGPU ( GPU integrated in the CPU ) if you don't have extra GPU to put in the first slot exit and save
  8. Boot into windows and wait just a bit to drivers load
  9. Open GPU-Z you will see the GPU there but you cannot use it yet because it is only powered by PCI-E only
  10. Open nvflash and flash back to working bios or vBios and have fun

Its Official I'm never ordering from Performance-pcs again, they litereally sent me the same 140mm fan i returned them for RMA, i got store credit and ordered another, and BAM then send me the same non operational fan!, and i RMA'd a non working LED, and guess what, this one doesn't work either. lol couldn't think of a place to post this, just venting tongue.gif

You did good! This way you warn people of the potential RMA issues of that company! thumb.gif

did you contact them to let them know this was happening? They are pretty much the only company I do business with, as they are instate, thus 5$ shipping is overnight... I recently RMA'd 2x DOA Typhoons... the ones i received back were functional... They have a rep here on forum, I would contact him.
