normal bios, without any modding, core clock gets to 1163

1- Remove PGR100



2- Short location PGR152 to enable VGA Hotwire Function



3- Remove XR192 to fix memory voltage in 3D voltage



4- For those who want to do OV without ASUS ROG MB.

a. Connect a variable resistor between OVG pin and Ground pin to over-voltage GPU voltage.
A 1.2Kohm resistor will over-voltage GPU to around 1.23V.
please make sure that you measure voltage in 3D mode while adjust variable resistor.

b. Connect a variable resistor between OVM pin and Ground pin to over-voltage Memory voltage.
A 5.5Kohm resistor will over-voltage Memory to around 1.7V.
A 1.5Kohm resistor will over-voltage Memory to around 2.0V. More than 2.0V is not recommend.

c. Connect a variable resistor between OVL pin and Ground pin to over-voltage PLL voltage.
A 11Kohm resistor will over-voltage PLL to around 1.1V.
A 4Kohm resistor will over-voltage PLL to around 1.2V. More than 1.2V is not recommend.






Thank you Coolice@kingpincooling.com! thumb.gif

ive oc´ed my ref 780 to 1000mhz and it boosts to 1149mhz with 106% powertarget(1125mv)
ive let it run furmark burn in test for 15min and saw no artifacts.
is there stil i chance that i might fry my card?

1.125v is pretty conservative but you might if you keep using Furmark.

i was only using furmark to test the stability smile.gif
ive been running on 900(939) for months without testing it so i went directly to 1000mhz and wanted to be sure my card could handle it

I don't know how dangerous it is but there are threads where people say Furmark killed their 780. It is generally not recommended to use Furmark with GTX 780. Do your stress testing with benches and games.

ok thanks smile.gif
thank god i only ran for 10min then smile.gif

Furmark is not suitable for testing stability!

You can test if your cooler is capable of keeping temps in check at an absolute maximum usage which you will never see in daily use but thats it with Furmark so don't use it for stability testing. Use benches or games preferably Far Cry 3 and Tomb Raider for games and Unigine Valley or Firestrike for benches.

What settings did you use in Furmark? 1080p 8xAA burn-in? Try it without AA and 1050p and you will see how your card will downclock because it'll tun into power target.
