What I concluded is the range for overclocking the gtx 780.
 
1000-1100 meh OC
1100-1200 decent OC
1200-1300 great OC
1300+ best case OC

Trabe3, how are you recording what the core clock boots to? In 3dmark it isn't listed that I can see, and in Precision X, I can't see the GUI while the 3dmark runs.

I have Precision X open on another monitor.  Couple of options, if that isn't possible.  Run the benchmark and then as soon as it finishes, pop open Precision X and check the performance graphs.  It should still have the peak value shown.  Another option would be to download GPU-Z.  Then, if you go the sensor tab, you can select the core clock and it should keep the max value during the run.  There is probably some other options, but can't think at the moment.

I have dual monitors, but 3dmark blacks out the 2nd monitor when running the test for some reason...

Yeah, I think mine does that.  I usually use Unigine Heaven and Valley benchmarks.  Those don't black out the other monitor.  Those are free benchmarks, I would definitely check them out.

Here's the results I got from running my GTX 760 4GB (Reference blower) using 3dmark on the Firestrike "Extreme" test for best results(score) without crashes so far:
 
Power Target 115% (MAX slider)
Temp Target 95° (MAX slider)
GPU Clock Offset +200MHz
Mem Clock Offset +240
 
GPU Temp hit 62° max
 
GPU-Z Report:
GPU Clock 1180Mhz Memory 1622Mhz Boost 1233Mhz
Default Clock 980Mhz Memory 1502MHz Boost 1033MHz
 
Any suggestions, or additional tests or configs to look at or run?

Hi,
Is the offset applied on the base clock and it can apply boost after? I don't understand the clock reported vs what offset I set. It's never the same. Sometimes 1268, sometimes 1019
Someone with an explication?
 
 

EVGA 780 ACX OC
Power 105%
GPU +90Mhz
Memory +70
Custom fan settings (60% at 50' - 90% at 80') and Voltage +25 mV.
Temp never higher than  67-68 C. Zero crash or problems from week.
 
My test showed: 106% power unstable under Heavens or Valley. Every step over +90 GPU or +70 Mem effect in higher max fps in benchmarks but, what is more important, much lower min fps (like 5 or 12). I tested with 105% power from 60/60 to 200/500, 150/300, 120/150, 120/120 etc end finished with 90/70 100% solid.

Hello there, i´ve been reading this thread since yesterday. I Have an EVGA GTX 780 SC ACX which i would like to try to squeeze just a little more performance. I'm currently using the Valley benchmark program and the precision X from EVGA to control the clocks and all. I tried to replicate the configurations mentioned above but without success. I don't understand one thing. First, i need to increase the GPU clock right? For example, if i raise +50 mhz, should i increase the voltage too? How much? And the power target? Should i change that or keep like default? I have a i7 870 which i already overclocked to 3.9 Ghz stable. I have a Gigabyte P55A-UD5 and a Corsair HX 750W, with 8 Gb ram DDR3 1600 mhz. Can you guys help me out?
 
Thank you so much in advance.

Being an over 6 year old thread ... I'm not sure if you'll get a reply
 
I'm not sure How well EVGA Precision X1 works on the older cards .... or are you Using Precision X OC ?
 
 
I'd web search for OC guides
 
780 are Before NVIDIA's baked-in Boost control.  These older tech GPUs - required more testing & usually a Custom BIOS tweak for "Best Performance"
