Such an extreme overclocking requires very efficient cooling, that’s why Kingpin used LN2 for this job. He was able to run 3DMark11 Performance Preset test to reach 15731 points. Benchmark rig was equipped with Intel Core i7-3930K overclocked to 5605 MHz, and also 16GB of DDR3 memory. Most important part was EVGA non-reference card which was overclocked to 1958 MHz for core and 3734 MHz for memory (that’s effective 14936 MHz).

He promised to do his best to reach 2GHz core clock and as we see he’s not very far from that.

It goes to show that if cooling technology could dramatically increase we could all double our performance.

They're doubling an extra time in there. It's really 7.4Ghz effective (which isn't really impressive considering the core clock). I run mine at 7.0 Ghz effective.

They actually do it right. He uped the memory clock from 1502 to 3734. Considering its GDDR5 you multiply that with 4 to get the effective clock :)

Zooming in on the gpu-z link still leaves questions as to what the memory was o/c to. He use gpu-z 5.9
TPU got it up to near 1800mhz in his gtx 680 review. On air/normal test bench.

I see the GPU-Z link now. Yes. Before I hadn't zoomed in on that mess of pictures.

Someone needs to crack these bios already... The reference 680 has a lot of untapped potential just wasting away :(

Not if nV designed the components to handle around 225W and not a lot more. Start cranking the juice and the VRMs could start going pop if that is the case.

sorry but I do not believe they got the memory to run at 14936 MHz. that memory is only rated to run at 6000 Mhz and some reviews could not even get 7000 Mhz out of it. no matter what magical cooling was used, 14936 MHz just does not sound possible at all. 7468 sounds much more plausible as even that would be great for that memory.

A combination of the bios and just-good-enough components on Nvidia's reference designs. Hopefully custom AIB boards will have their own bios, as we can already assume they will improve upon the reference board designs.

Even if you can crack the bios there is still a limit in terms of voltage.

I got an extra 100mhz out of my GTX 460 by tweaking the bios.

Memory wasn't clocked that high lol come on dudes. That GPUz screenshot is all fuxed anyway.
