Just tried this on my new GTX 760. I get around 250 KH/s although when I came back after a few hours it had dropped to 200 KH/s and was feeling rather hot to the touch, although i didn't think to actually check its temp. Anyone else got a GTX 760 to compare to?

Yes, I have tried that but it will not Work.



Anyone have an idea why it will not Work?

Did some testing on the X-perimental kernel (test_kernel.cu) on my GTX 780 Ti, slightly overclocked.

compiled for Compute 3.0: 510 kHash (no funnel shifter and no texture cache used)
compiled for Compute 3.5: 620 kHash (standard Titan kernel with funnel shifter and __ldg() based scratchpad access)

doubled the ALU workload (salsa_core called two times in each iteration): 340 kHash
removed the ALU workload (salsa_core replaced by an empty function): 694 kHash

Hence we're nearly bandwidth limited and we fully saturate the ALUs, it seems. So it doesn't appear that we can implement a LOOKUP_GAP with any speed-up. There's no way we can trade memory bandwidth for more computation to gain speed.

Also I ran some tests on Linux where overclocking of Kepler devices isn't an option.

With the standard BIOS I get 515 kHash
With the skyn3t-Ti vBios I get 585 kHash, but intolerable heat emission and power draw (apparently the default voltage is set very high)
With svl7's GTX 780Ti "OC edition" rev 04 vBIOS I get 560 kHash with only a slight increase in power draw.

So I guess for building a Linux based mining rig using the 780 Ti, it's currently the best option to use svl7's BIOS. Still, a GTX 780 overclocked on Windows will provide more kHash than a 780 Ti using the modded vBIOS.

I'm sorry have mist that.

Thank you for cudaminer! I got a 41% increase in speed from 2013-12-10 to 2013-12-18.

Very happy with cudaminer at the moment.
with the latest release and playing about with settings I have got my EVGA A/C Superclock 780 to run at 550Khash/s

This is my config cudaminer.exe -i 0 -H 1 -m 1 -l T12x16

my overclock settings  too http://imgur.com/WoxJGJU

Gotta give a shoutout for my case too silverstone raven rv02
It is an amazing case and really impressed with the airflow and cooling.

Would the cuda 6.0 tools have any benefit to us when thats release? are you planning to update cudaminer with 6.0 tools?

Just loving you man, hash speed increased a lot

thanks again, i'll send you 1 LTC once i have !

I plan to add a percentage scaling for mining intensity as well as temperature throttling in software...

great to see other people hitting a megahash with a single nVidia equipped PC...
