Hello all,

Last year I had the supreme pleasure of winning a 780 at the gaming convention PAX East for coming in first in a tournament. Since then I've really lacked in GPU power, until I bought Witcher 3 and did some research.

I know that I'm not going to be able to run at max settings on 60 FPS (That's a job for a 980), but I'm able to run at max on 30 FPS. However, during some of the more lighting intensive scenes I do get some stuttering and texture lag.

I've traditionally used MSI Afterburner (way, way in the past). I opened it up yesterday and tweaked the memory and core clock a little, but it was a very roughshod process. I just made sure it didn't run too hot on load.

I was wondering if there were best-practices to follow? Certain core-to-memory clock ratios?

I've been out of overclocking and hardware in general, and it seems I've forgotten most of the nitty gritty. I have a dxdiag if anyone needs or wants it.

I would research good set ups and incrementally build towards those.

With the 7 series onwards, OCing changed in that temp targets became more important and you have several ways of getting the best out of your card. Ocing has become more personal.

You can now define whether to massivle overvolt and stabilize an overclock, paying the temp penalty, or you can tell the card to sprint right until a certain temperatrue level and not exceed that.

As such, you should read into it a little and define what you are after. Cool, consistent or hot and high performance OC. There are obviously other combos.

Also, since your card and mine share a lot, i think you will be bale to set a custom fan curve, which will help you OC to certain temp...

Great fun!

I'm pretty lost with all of this. I look at this thread, for example, and see people posting their clocks.

They all seem to know the exact model of their card, but all my system is telling me is that it's a 780. I'm worried I'll be benchmarking myself against a stronger card.

If you have a 780, then you have the same card as them. Some are factory OC, only difference.

Use GPU-Z to determine your card and clocks.

Then use Afterburner or EVGA precision to OC. Google some OC guides for those and using the 780.

If you find nothing, use the 780Ti or original Titan as a guide. Very similar.
