GTX 780 Owners Club

I need a knowledge bomb after reading mrk's post.

I'm running +150 offsets so 1012 GPU, 1123.5 boosted and 1652 Mem, 6608 effective.

I have not touched my power or temp target and my 780 seems fine running Heaven 4.0. Just to see what would happen I upped the power and temp target to 106% and 94c and ran Heaven again and nothing changed.

Am I missing something? is it his 300 mem offset requiring him to do this? is it silicon lottery not requiring me to do this?

Answers greatly appreciated, I am new to this software.

When overclocking you should max out the power target. Don't know if its the same with the 780 but even increasing the power target at stock speeds on my 670 gave higher benchmark scores. Temp target won't affect much but you should set a custom fan profile to keep the card below 80 if possible so the boost clock is at its highest all the time.

Temp and total power draw will limit the cards boost clocks often before the power target exceeds 100%.
Banging sliders to the right is really just a request and when the load is high the cards power management will override to it's pre determined limits anyway.

Yeah the 780 does the same. My power target is set to 106% and the temp slider is locked in sync (I don't unlock it) so 94 degrees. My card goes to 84 degrees when gaming and the fan speed ramps up to around 55-60.

worth going for 1 already got a 680 but have money burning a hole + a lot of over time :)

I wouldn't why not wait for the release of the 770 and see if there are any prices drops (yes I am optimistic) on the 680 and pick up another one for SLI? Would be ther cheaper option.

But of course if SLI isn't your thing and you can justify buying a 780 then go for it :)
 
Stock boost

What boost is everybody getting?

My card automatically boosts to 979.8MHz without any o/c software even running.

Not bad tbh as advertised is only 902MHz boost.

Max core o/c is 1175.8MHz (36% above stock speed of 863MHz!)

Not bothered with over-volting as yet.

moogleys boosts to 1006 stock which might explain his scores ;)

Having a boost much higher than is advertised is normal, whats advertised is the minimum. It was the same way on the 6 series.
 
Mine arrived and currently testing it before I put it under water in my main rig. Seems a shame to replace the cooler it really does feel quality.

 
Seeing people posting quite high temps here.

Still +150, +100 atm and in game it hits 60° at 60% fan speed, not had it go above that yet. Perhaps I'm not pushing the OC hard enough for the higher temps, or maybe differences in case cooling.

I wonder why that is?:confused:

I'm not overly worried as I use precision (with a mild o/c) all the time anyway, but its worth discussion...

It's normal when you are running sli, depending on the cards position in the setup it will boost a different amount to the other card(s).

I have also seen this with GTX 690s, even the two GPUs on the same card boost to different speeds.
