780ti Overclocking Advice

[davey767]

I've just purchased my first 'green card'. It might not be my first, but I've been a loyal red for many years now. I have installed EVGA Precision and started to have a play about. I'm not to clued up on all this, so I just wanted someone to confirm I have done everything right.

I own the 780ti EVGA SC.

I set the power target to 106%.
I unlinked power/temp target.
I set the temp target to 85%.
I set the GPU clock to +135 mhz.

I've left the fan speed set to auto.
I've left the memory alone.

After running Heaven for a while, I have found the GPU clock boosts to a steady 1241 mhz. Temps hit 85 degrees and the fan speed is around 55%.

Everything seems to be running great.

Am I missing anything though? I'm gaming at 1440p. I'm not really interested in benching or anything. I just wanted to make the most out of the card. I just don't have any experience with the Nvidia. Stuff like temps, should I set the max temps a little lower or higher?

Any help would be appreciated.

Those seem like perfectly normal clocks and if they cope nicely in games, that is all that matters.

It is good to run Heaven at stock clocks and then again at your overclock and see the free performance gains

Heaven score was 1593 with the standard SC O/C.

It's now at 1737. That is using the rules set out in the Heaven thread.

 

[Gregster]

So a 9% gain. Not bad at all

Cool. If I leave everything as it is and push the clock a bit further it doesn't seem to like...

 

[davey767]

Noob question incoming. I see a lot of benchmark results showing 1293/1906 and 1332/1630 for example. I understand that the first number is GPU clock and I would have thought that the 2nd number was the memory clock.

Shouldn't the memory clock be more like 3000/6000 though?

Confused...

 

[Silent_Scone]

Some people choose to put the effective clock, others don't.

 

[davey767]

So when people put 1500 memory, that could also translate to 3000 or 6000? They are all the same really?

What ever memory speed you have in precision you double it for the overall speed. Other programmes like gpu z you times it by four. 85 is on the high side for prolonged use (specially given it's not summer) so I'd make a fan profile. See what a bit more fan speed does for temps as 60-65 percent should knock off a few degrees.

3000ish numbers are 2x base, the 6000ish are 4x.

just multiply your results by 2x or 4x if you want to compare.

Slight thread hijack, but what causes a ripple like effect? I tried overclocking and the heaven benchmark score improved but visually the graphics were just not as smooth as when running at base clock. It was a bit like an ocean wave going through the screen and- with a few more slight pauses than when running base clock. Seemed to occur with even just a small OC.

Sounds like screen tearing due to not running vsync.

Nonsense. The temp target at stock is 83c on these. Those temps are fine. For 24/7 temps anything below 95 should be perfectly safe.

Agreed with Matt. Anything that goes over your monitors refresh rate has a chance it will tear.

Spoiler

Most gamers have just accepted this as the norm and got on with it or used V-Sync, which is fine for slower paced games but games like BF3/4/COD, you get input lag when you have V-Sync on (slight delay between mouse/keyboard movements).

Thanks. The fan curve feature is pretty cool. Doesn't go over 80 and the fan is still miles quieter than my old 7970 ref card. Well impressed.

My card seems happiest at 1228/1873. Happy days.
