24/7 Overclock on 2 EVGA GTX 780 Classifieds

post #1 of 2
Thread Starter 
So, I'm trying to figure out how I can get a decent 24/7 overclock on my graphics cards. I've never really overclocked video cards before, but I'm currently sitting on two 780 classifieds with EK water blocks.

Using the classified controller and Precision X, I got both cards to a stable +252/278 (to get both cards to the same speed) core clock and a +351/351 memory clock with a voltage of 1.35 in the classified controller. My temperatures never got over 46 degrees Celsius and it easily handled Valley and Heaven benchmarks + 30 minutes of Far Cry 3 with no artifacting.

I feel that I can easily push both cards higher, but I'd like to figure out a way to be able to overclock them further while also keeping adaptive voltage so that when my system is idling its not pulling 1.35 volts for absolutely no reason. Is there any way I that I can achieve this? I haven't tried flashing the bios, as I'm not exactly sure what that would accomplish that the classified controller wouldn't. Thanks in advance.

First welcome to the site. There are lots of information laying around the internet such as youtube and etc; however, when it comes to overclocking either cpu or gpu, you've got to be careful due to possible damage to your devices not to mention complete totaling 'em! Nevertheless, there are good softwares out there to overclock a gpu.
What I've known and used to overclock my gpu is MSI Afterburner(works for Nvidia and ATI), and to test I use 3dMark11 or PCMark7.I am not the pro, but I know what I am doing. I believe there are more people out here to give you more information to help you out. My personal suggestion is , just go online and look for the specs of your gpu (such as idle temp, max temp, normal clock speed and the max, under what voltage that the gpu can run max and min, etc..).
Once you got 'em, download and install msi afterburner and adjust the clock speed at least and not go over the %20 less of the max output.
then play around do tests, run benchmarks to see if it is stable, if not lower the clock and other changes till got what you want.
I hope this would help a little bit!
