Overclocking

To put our Nvidia GTX 780 to the test I used a beta version of EVGA precision that supports the new card. To test my overclock I used test number 2 on 3DMark 11 set to performance settings. I started by doing what most would do when overclocking. I cranked the fan up and pushed out power target and new temp target options all the way over. From there I started at 100 MHz then 200 MHz GPU Clock offsets and both passed my test. Next I went to 300MHz and my test failed right away. After rebooting everything I knew our best clock speed was somewhere in between 200-300MHz offset so I slowly turned down the clock until I was able to get it to pass. The end result was a GPU Clock Offset of +220 MHz and a GPU clock speed of 1215MHz total.

Once I figured out our max overclock without touching the overclock I tried to play with the voltage but it actually lowered my max overclock. This told me that my overclock was most likely limited by power or temperature limitations; I would need those limitations in the software to go higher. It’s nice to know that the GTX 780 has lots of room for overclocking though.

and a huge hit on my wallet, excellent review Wes, very informational and the small section of the overclocking was impressive. Pretty stoked for the cards.

even those of you who aren't looking for a new card should read the "geforce experience" section
