Thats a nice overclock you got, I crash if I push mine past +125 GPU clock, I have power up to +250% and +100mV, +600 Mem Core. Temps stay under 60c. I just reset the global settings in nVidia control panel to default and with this new overclock I have the following results. Pretty decent! What else can I do to possibly get a higher GPU clock though?

Here is my result on Heaven with the same setting as you guys :


weirdly, when I run it on Extreme preset it screw it totally, like Valley bench, uses the GPU2 @ ~98% but GPU1 is not used, it stick to ~50-60% usage, huh!
edit: apparently, the newest nvidia drivers are baaad for SLI

Amazon has the Lightnings back in stock for $499... Wow, I'm tempted... Anyone think I'll be strapped by the VRAM though? I game on a 1440p monitor that OC's to 120Hz. I don't mind not using AA at that resolution.

Looks like the 1400 neighborhood is about normal for a single Lightning @1920x1080. It's great that you get almost double that with SLI.

kickflipper, one thing that might improve the OC: set aux to -100mv or -50mv (try both, see which is better for you). But it is not really important if you can't go higher: the difference between 1454 and 1379 is measurable, but not *noticeable*

I can see why, score wouldn't be bad with extreme tessellation set, but that looks bad for moderate, I don't know...

One possibility is that you've overclocked it too much. Taking an OC too far can degrade performance. Cache errors, mem errors, re-reads, re-writes, mean going nowhere incredibly fast.

But maybe it's just some settings not working with heaven. Have you run other gfx performance benchmarks? How did they turn out?

Just picked up a couple MSI GTX 680 Lightnings to replace my old ATI 5970 thats starting to fail (video artifacts and random crashes when artifacts get bad). Came in today from Amazon. Also have a couple of EK blocks coming in from ebay. Made a 105 offer on them and got them down to 110 each; down from 113. Not much but something. Search for auction ID 380590538236 if your interested. 2 left.
Questions:
With EK blocks someone mentioned missing thermal pads. So what did you use to replace? Is there a thickness to order?

What thermal paste you guys slap on the GPU? Can it be conductive? Was thinking of ordering Phobya HeGrease Extreme.

Anyone watching voltages externally? I was thinking of something like "FrSky lipo voltage sensor". Looks cool, but connection not possible with wires meant to measure ground off the hot end of the last cell. It also consumes 15.5 mA. Not a load I want to put on a test point. Dang have to find something else.

I need to order a bridge. Thinking of the clear one to help with visual bubble removal. Wish the block was clear also. Also need to order some lower profile connectors for my optical drives so the last card will fit. Silverstone case vertical card solution has the SLI cards up against the optical drives. Rambling now.rolleyes.gif

Thanks for any input .redface.gif

I don't know the 680 waterblock specifically, 0.5mm is the most common one I see on other EK blocks, & a couple use some 1.0mm as well.

For voltage monitoring the easiest way is a multimeter.

Watch of for 3 slot vs regular EK bridges. I've made bridge mistakes twice now. You NEED the 3 slot if you have a free expansion slot between your graphics cards (looking at the back of your case). Doesn't matter if there a pci-e x1 slot there or not....go by the back of the case.

No point in using conductive thermal paste. You can get non-conductive white stuff that performs just as well and is far safer.

It's .5mm pads on the memory and 1 mm on the VRMs. I got what I needed in the box without ordering extra.

I use a multimeter. Don't care after initial debugging what the voltage is....gaming it will be 1.368V and idle it's 1.098V.
