Firestrike Extreme --- 4930k @ 4.8GHz --- 780TI SLI @ 1295 / 7400 --- 10944

http://www.3dmark.com/3dm/1977985ark.com/3dm/1977985

Valley - 4930k @ 4.8, 780 Ti SLI - 1295Mhz / 7200Mhz - FPS 138.3 - score 5785



This is with the SkyN3t bios, about the limit for my cards on air...going to try single cards too and see if I can go higher but even with Windforce fans @ 100% I came close to 80c.

Does anyone have issues with 3Dmark 11 and the 780?

I can't push the same clocks in 3Dmark 11 as I can in Firestrike/Valley...Best run I had in 3Dmark was 25,075 at 1241/7100, but can push 1295/7400 in Firestrike/Valley.

That's pretty standard. Valley is much closer to an epeen bench than a stress test @ this point.

Cheers.

Just seems odd...on my 290's I could clock higher on 3DMark 11, but had to down clock for them to pass Firestrike, complete opposite with my 780's.

So i reseated my GPU heatsink again(stock) and used PK3 thermal paste. Now i am seeing 73 degrees @ 75% fan speed @ full load @ 1.212v. If i put the fan at 100% i get 69 degrees tops. Honestly if you reseat the stock heatsink and use better thermal paste i would say the stock heatsink is very viable. I imagine with some really good thermal paste the ACX cooler should be even better.

I also found(at least for me) setting the unigine.exe 3D settings to "maximum" performance thus keeping the power state static gave me better results in valley. I went from getting around a 3000 score to about 3200 on average. It seemed my card kept downclocking during in between scenes due to the extra down time the slowness of my standard HDD causes. I really just need to get a solid state drive.

Lastly i have found the 780ti to be the best downsampling and monitor overclocking friendly card ever. I have been able to push a lot of my previously established profiles for overclocking and downsampling about 10-15%. Running Dead Space 3 on my Qnix(1440p) downsampled to 4k and still maintaining 80hz was just awesome(also downsampling dead space makes the ported graphics limitations not as bad).

What do you mean downsampling to 4k? What is it exactly and how do you go about doing it? Running a qnix as well.

This is supersampling with the rendering hardware of your video card. It is not actually showing true 4K but a supersampled aliased version of it. This is going to be vastly better than regular AA, MSAA, FXAA or any regular kind of aliasing. here is some reading for you.

I have mine able to downsample as high as 5120x2880@60hz using difference data rate bios tweaks. Honestly 4K or 3840x2160 is as high as your really going to want to go since the FPS will drop too much going to much higher. Honestly with the Qnix your two best choices are 1440p@120hz overclocked or 2160p@60hz downsampled.

Lets just say is a way/trick of showing resolution of 2560x1440 or higher on a 1080p monitor/hdtv.


How you do it:

1) Open NVCP-->Display-->Change Resolution and you will see a "Customize" button below the available resolutions. Click it.

2) Select "Enable Resolution not exposed by the display" if its not selected(leave 8bit/16bit unchecked) and click "Create Custom Resolution".

3) In this new window just change the "Horizontal pixels" to 2560 and "Vertical lines" to 1440 and leave all else as is.

4) Press "Test" and the screen will flicker/flash and show the new resolution. If its successful, press "Yes" at the small confirmation window and then select "Ok" since you are in the "Customize" section now. Press "Ok" again in the NVCP to exit.

5) Try some games which all should have 2560x1440 as an option and enjoy better looking games. Note that your card is rendering @1440p so set your game settings accordingly if necessary. thumb.gif


Edit: The 4K downsampling is a bit more hassle sometimes. In the 3rd step above type Hor. Lines 3820 and Vert Lines 2160 and press test. If it works continue with the steps.

If not, then you will need to tweak the timings settings in the "Create Custom Resolution" window.

So select "Manual" in the Timings section below and start using the timings 1 or 2 or 3 or 4 from the screenshot below in that order, until one works.. wink.gif

Direct link full resolution 1920x1080: http://cdn.overclock.net/5/52/5237e78d_nEvHEvO.jpeg

Warning: Spoiler! (Click to show)

Done! Now you can enjoy 4K gaming on your 1080p or 1440p monitor/HDTV. thumb.gif
