well the card worked great up until v8 got into my queue and that's when the whole shabang started Oh anything's possible. Boinc and applications have known quirks (though none that I' know of that manifest like that yet). Simply confirming it behaves exactly the same way at 200 Mhz lower will confirm your suggestion that your factory overclocked GPU is (probably) stable, and the problem likely lies elsewhere. Then it's easy enough to put it back again and remove the applications involved. But first there are many components involved here other than just applications and GPUs: Given the increased precision in v8 raises the CPU demand (no GPU code changes at all actually), Are you quite sure that Pentium edition processor is enough to feed a 780 ? If running multiple tasks and pegging the CPU cores, you may have better luck dialling the (CPU) load down a notch, reducing instance count (if applicable), and raising the GPU app process priority by one level. FWIW my 3Ghz Core2Duo does manage to fill the GTX 980, but never been quick enough for Full loading and pegging the CPUs as well. [Edit:] SETI@home using CUDA accelerated device GeForce GTX 780 With that 2.6GHz CPU, A free CPU core for 1-3 GPU instances, blocks per SM 8, periods per launch 200, and processpriority normal, IMO would both give the CPU a bit more breathing room, load the GPU a bit more, while still not pushing that GPU. always room to raise or lower the settings as well though if the opposite effect is noticed.

the card is at factory default i got no idea why nobody reads it i have said it many times IT IS AT DEFAULT The problem is that it's not at the factory default. Base Clock: 967 MHZ Boost Clock: 1020 MHz Those are the factory defaults; higher than the reference card defaults, but still much lower than your card is reporting. Grant Darwin NT |

Sorry if I caused confusion. It looks like we have two different issues on two different boards being discussed. All the 750ti stuff I mentioned is moot in relation to the board in question, a 780. Blood alcohol level was dangerously low at the time ... :) |

the card is at factory default i got no idea why nobody reads it i have said it many times IT IS AT DEFAULT Lot of variation in those numbers depending on which model and whose board ... in some cases as much as 100 Mhz. Whose 780 is it? Which submodel?? |

Whose 780 is it? Which submodel?? If it's a GTX xxx SC it's an EVGA. The GTX 780 SC specs I gave are from their web site for that card. http://www.evga.com/Products/Specs/GPU.aspx?pn=C811FD6B-7E4F-4C02-9839-9C581D7B338C The GTX 780Ti SC specs are Base Clock: 1006 MHZ Boost Clock: 1072 MHz http://www.evga.com/Products/Specs/GPU.aspx?pn=E4755EA0-12DF-4F22-ABA3-650C494D83DC The GTX 770 SC specs are Base Clock: 1111 MHZ Boost Clock: 1163 MHz http://www.evga.com/Products/Specs/GPU.aspx?pn=FA93EFC9-A44B-448C-BCEA-AFF0B5BD7AEB And the GTX 980 SC Gaming card. It's specs are Base clock: 1241 Boost clock: 1342 http://www.evga.com/Products/Specs/GPU.aspx?pn=472a80bc-9a78-45b1-8560-6fa1916330e8 Zombu2 is adamant it's a GTX 780 SC, and the clock speed is 1201MHz. And that's what's being reported in his Stderr_ouput. However that clock speed doesn't match up with the official specs for the GTX 780 SC, and it doesn't match up with the next 3 closest models either. Hence my curiosity as to what GPUz reports, are the PCIe clocks on spec, and is Precision X running at all on that system? Grant Darwin NT |

My .002 on Precision x 16 is that it gets so funky you end up not having any idea where you really are ... Thanks for clarifying ... |

There is also an EVGA GTX780 Classified, which is what I am running on this rig right now. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

There is also an EVGA GTX780 Classified, which is what I am running on this rig right now. They're certainly built for 1200+. Yours isn't spitting any invalids is it yet ?

Now 1241, +100Mhz. I don't think it's even breaking a sweat yet. 58c with dual fans at full speed. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Now 1241, +100Mhz. They have Cherry picked parts (GPU die, VRAM chips, Capacitors etc), beefed up power circuitry and thermals, special firmware. I wouldn't be surprised if you can pass 1400 with volts etc, and end up faster than at least reference 980s (if at some relative power/thermal disadvantage, it should be able to take more) "Living by the wisdom of computer science doesn't sound so bad after all.

I looked at your last AP and it shows the clock rate as 1019, which is about where it should be. I then went to the same time frame as that AP and found the cuda tasks around a "normal" clock rate. Looking ahead and backwards from that point it appears that when the machine is restarted it uses a Different clock rate. It will use that rate until it is again restarted. I looked at other 780s and noticed their rate was pretty consistent. So, the question is what is changing your clock rate after a reboot? now here is something i can go on .... Indeed it is quiet weird why it would do that ...i wonder if precision is going heywire ... i checked everything kboost oberboost overvoltage etc everything is off and at default exept the fan it is running at 100% i'm gonna reboot it a couple times and see if that changes it and actually do a couple turn on then shutdown pull power from it and reinstall a clean driver @Jason_gee The early titan cards are based on the 780 chip so i bet if you get a good one you could ...gotta look at the asic I came down with a bad case of i don't give a crap |

I looked at other 780s and noticed their rate was pretty consistent. So, the question is what is changing your clock rate after a reboot? Based on the figures others have posted & what I am seeing with my 750 ti FTW running well over the spec'd clock rate. I would have to guess that EVGA has not implemented a clock cap for the boost. Likely only being throttled by thermal and voltage limits. While my 750ti FTW is running at 1345MHz GPUz reports "GPU performance is being limited due to insufficient voltage". If you have a tool that allows you to adjust the voltage you could try lowering it until the clock is closer to the value in the specs.

The SSP shows we are still down but I was able to report 15 tasks, get 13 in return and the message boards are up. Now the SSP shows it is up, maybe the SSP is a bit lazy. |

well it seems the issue fixed itself not an invalid one since the 24th and i have not touched the configs since i was quiet busy the last couple days EDIT: it seems i might have found the issue looking at the logs by accident it seems v7 tried to run v8 tasks ....why i dunno but i stumpled over it on accident I came down with a bad case of i don't give a crap |
