Gtx 780 Windforce Overclocking

[TheHolyCawCaw]

Good morning/evening

 

So I recently started playing around with my gtx 780 Windforce and could get +190MHz on my core clock on stock voltage and it is stable for Valley Benchmark.

 

However I need to go down to +170-180MHz for stable Shadow of Mordor/ Modded Skyrim etc.

 

So when I try to put +200MHz Valley will crash always at the same point.

 

So I try to add more voltage but it keeps crashing at the exact same point in Valley even with +20mV.

 

Have I reached the max OC on my card?

 

 

As always thanks for the help

i guess so but increase power draw and did u increase memory clock of the gpu

i guess so but increase power draw and did u increase memory clock of the gpu

I maxed out power draw and max temp limit is 95.

 

I didn't change memory as it won't help much fps wise as I heard.

guess u reached gpu limit or cpu is bottlenecking it or psu has less wattage

Well probably reached limit^^

no cpu bottleneck and psu less wattage for sure

[salecar3]

no cpu bottleneck and psu less wattage for sure

What is cpu and psu

i guess no cpu psu bottleneck

What is cpu and psu

i7-4790k and 750W psu

whats the base clock on  yours?

I can put the core clock to +117 exactly on mine and bump the memory clock to 7.2GHz effective, but i need +37mv and in actual gameplay the drivers will crash at much muuuuuch lower speeds.

It seemingly tops out at 1228 boost and adding more crashes it/doesn't show any higher boosting.

base clock is 954MHz

same card as mine then.

 

With this one it crashes immediately upon valley start up if you have it 1MHz to high on core. You then have to back down 5MHz for it run stable. As for memory I've had it as high as 7.4GHz, but only 7.2GHz with core overclocked at the same time. Try bumping up the fan curve if you haven't already.  

 

These are my settings in afterburner for valley.    temp target 94c

Ty for sharing

 

I am going to play around a bit with the voltage and see if I can get +200MHz without crashing.

 

Then Imma see how much I can OC the memory.

 

Fan curve is good my temps are great.

 

Do you keep yours running like this all the time? I am never sure if the voltage will harm it^^

[asim1999]

Ur not the only one, i only managed to get +225Mhz stable on my 980 with +37mV

No, only for valley. Usually i just leave it at +100 on core and +37mv or default everything with custom fan curve. The memory overclocks a lot better than the core clock, but barely adds any benefit in anything other than benchmarks. I only really use the overclocks for short periods, say an hour or 2 on battlefield 4 where the extra fps may be useful. This card has to last me a while yet, so i haven't risked flashing the bios for more voltage.

 

Those settings i showed are my bench settings, they just aren't stable enough in actual gaming.

I got it to run with +200MHZ with +25mV and get 69,5 fps average on valley maxed out. Seems good

 

Need to test more when I got time
