I have a gtx 760 Ti . I am using win7 x64 with nvidia 334.89 driver.
I got a message along the lines of "Unable to query CUDA driver version! Is an nVidia drivernstalled?"
do apps like GPU-z and cuda-z show any CUDA capability? Logged in via Remote Desktop, maybe? pls see below for a screenshot. The tool named "PtsGPUz0.3c" which is ues to dig PTS coin(it's use CUDA device) can workable. You can remote my desktop if you needed. Could you pls let me know your SKYPE or MSN? thx  As GPU-Z indicates in that image, you don't have CUDA available, I am assuming you didn't select that while installing the driver? |

I can't believe this little 750Ti at $150 can outperform a GTX 670 at $400...
At a much much lower cost/watt!
And my GTX 780 barely gets over the 750Ti too! :/ (4.44khash/s YAC)

Finally I see my 1500 yacoin in bter.com now !
Glad to see this.
my friend's 4314 YAC are still in limbo. If bter.com doesn't resolve this, I will have to refund it out of my pocket - isn't that great? bter.com is dying for me, one failed deposit after another. Christian That would be... ouch! |

Be carefull with bter, I never received my last requested bitcoins from them, admittedly I never used their support about it either but I will, when I get home...

You know what, I am kind of sad that I sold my YAC for 0.000027 now :p
I'll go and get more when I get home lol.

I cannot really promise that this produces actual speed benefits. There's no specific new features that a compilation for sm_50 would provide and which sm_35 (Titan kernel) doesn't already offer.
One can only hope that the compiler does some better code generation when targeting sm_50.
Christian
Aha, this is where nVidia engineers could go ahead and shine then, making their compiler more efficient! |

This may be a stupid question but wth did you guys use to compile this? i tried vs 2010 express, vs 2012 ultimate and vs 2013 express and i keep getting that dam version not recognised from the cuda sdk (5.5)
page 130 has great list of instructions |

Damn it... Bought 3 with a portion of my Bitcoin haul from the Maxcoin launch...  EDIT: And today I become a Tittiecoin MILLIONAIRE!! That only makes 500000 ladies...  |

Those new nVidia cards will be great for laptops, if it uses 60W it can easily be used by a laptop these days! Why a laptop? Well it's possible to get free power for days at a time of course  It will probably take a bit for them to come out though, and my current laptop has shitty Intel HD3000  But yeah, a laptop beating the old GTX 670 with 300khash/s is just crazy! |

I raised it 5 and dropped to 20's, raised to 6 and crashed driver. I guess it will stay 4. Should I be worried that I do not see hashes accepted
okay, last attempt: how is -l F8x8 working for you? give it a bit of time. at low hash rates it may take a bit for shares to be found (and accepted). Depends a lot on the pool also and what default worker difficulty they use. Ha! You didn't sign your message with "Christian"! You totally lost your highscore there |

So my 3 ASUS ROG MARS cards with 2 GTX 760 chips on one PCB arrived. I am currently having some thermal issues with the cards not receiving enough air. Some of the fans run 100% and the GPUs still show 98 deg C. And this is with Yacoin which doesn't max out the TDP fully  Christian Conclusion: NEVER buy a video card with those stupid two-fan coolers! They may be a bit more quiet if it´s your only card in the system, but as soon as you have a second card, you´re gonna hate them. You couldnt have said this a week ago? :p haha Yea with 2 cards my top card hits 78 degrees :/ Its getting a little scary at that point 78C isn't THAT bad, my single GTX780 hits that all the time, and the fan doesn't go >70%... Also my laptop (no GPU but CPU mining yacoin is better than nothing) hits 80C... it's silent but the fan goes 3800RPM... Vague stuff. |

So my 3 ASUS ROG MARS cards with 2 GTX 760 chips on one PCB arrived. Album link here!Some impressions: -cool red blinking MARS logo on top. Even cooler than the GTX 780 TI's. -nice metal back plates, but the plates do take space and so the air convection in the narrow space between adjacent cards is degraded. -nvidia-smi under Linux (hacked with nvml_fix) shows a TDP limit of 214W per GPU. REALLY?! That's then 428 W per card. I am currently having some thermal issues with the cards not receiving enough air. Some of the fans run 100% and the GPUs still show 98 deg C. And this is with Yacoin which doesn't max out the TDP fully When I forgot to remove some plastic protective cover from the back plates, it got sucked into the fan of the adjacent boards. I had to cut the power immediately to clean up this mess... Power draw seems to be 900W when mining near 20 kHash/s. Christian Were you so exited about the cards that you didn't notice the big warning text on the back?  Congratulations on getting it running! Hope you get amazing results |

We all know what is desired for mining: Low power usage
Low temperature
Cheap
Multiplicity: Stack as much cards on ONE board. Now what you guys are asking, a card with its own USB ports and ARM processor, is stupid. That means for 10 cards you need 10 USB drives with 10 Linux installations, 10 network connections and 10 power supplies. Not to forget to mention that the card gets more expensive because of the added logic. |

now it doesnt crush but it doesn't validate with the cpu hmm (and yes i am at stock ;P) thanks btw!
EDIT 1: My bad I forgot to put the MRC instead of YAC... Is 315 khps for the gtx 780?
EDIT 2: sorry again I mean 157 khps (I use 2 gtx 780)
I am getting about 480khash/s with my Asus GTX 780 (Factory overclock), so I am sure you can get more out of yours. Kernel config: -l T12x24 or T24x24 (Latest being a bit more screen laggy) You get 480 from 1 card? :O Yes, with MicroCoin, it that special? I seem to have a "lucky card", it automagically clocks itself higher than the factory overclock suggests. |

Thanks OP for the software, Ive just herd about today and will test soon. ty.
Be sure to read the readme and search the thread! |

You had to quote the whole first post for no appearant reason  |

I should've solo mined microCoin, according to the pool I found 2 blocks already, while the pool is at 147k reward |

Unified memory isn't really helping in terms of speed, only in terms of code simplicity.
I'd rather be in full control, having to write a bit more code though.
Hmm yeah I read a bit more, sounds like it "hides" the code to copy from CPU to GPU, rather than extending CPU to GPU. |

These boxes aren't called troll boxes for no reason! CUDA 6.0 RC is available. You have to be a registered developer though https://developer.nvidia.com/usercompile cudaminer and compare results. the T kernel for keccak might be interesting to check out. In CUDA 5.5 it gives a rather shocking performance. Christian Meh too much questions, can't really say I am THAT much of a developer... Edit: Unified Memory -- Simplifies programming by enabling applications to access CPU and GPU memory without the need to manually copy data from one to the other, and makes it easier to add support for GPU acceleration in a wide range of programming languages. That, scrypt-jane anyone? |
