Don't forget to update all your machines! ![]() Soon we'll see a much higher RAC of you.. ____________ [Optimized project applications, for to increase your PC performance (double RAC)!][Overview of abbreviations, which are used often in forum and their meaning.] ![]() |

Uh oh... I also tried updating the gpu driver but computer didn't like it. screen went black several times and message came up saying "driver stopped responding and recovered". changed the driver back too 19107. gpu temps in the mid 90's. Maybe oc'ed too much? |

Thank you for everyone's help. Followed Sutaru Tsureku suggestion and installed Lunatics_Win64v0.2_(SSE3+)_AP505r168_AKv8bx64_CudaV12. I hope this is the correct one. This computer has a 1000w psu. Using Kill-A-Watt, it is drawing ~600w for everything. Now I will get to watch you fly by...LOL Official Abuser of Boinc Buttons... And no good credit hound! ![]() |

Uh oh... I tested 190.x , 191.x and 195.x on my GPUs (OCed GTX260-216) and 190.x was the fastest. WinXP 32bit. 191.x was little bit slower, 195.x much slower. http://www.nvidia.com/Download/Find.aspx?lang=en-us [current the international DL site don't work] http://www.nvidia.de/Download/Find.aspx?lang=de [the german work] 190.x is also available for Win7 64bit. If this is only a pure crunching PC, or you work or play also games on this PC? If pure crunching PC, you could take 190.x . Before installation of new nVIDIA_driver I uninstall the old. You have the 2x PCB (old) or the 1x PCB (new) GTX295 ? The 2x PCB have one GPU chip on one PCB. The 1x PCB have both GPU chips on only one PCB. [http://www.computerbase.de/bildstrecke/25716/1]_some pics (1st pic, the left one is the 2x PCB, the right one the 1x PCB) If you have the 2x PCB GTX295, maybe it would be well to set 100 % fan speed. Or lower the OC. Which are your OC settings for core/shader/RAM (what was the original) ? If I would have more than ~ 85 °C (running 24/7) I would worry about. Not only the GPU chip would be very hot also the RAM and the voltage transformer. ____________ [Optimized project applications, for to increase your PC performance (double RAC)!][Overview of abbreviations, which are used often in forum and their meaning.] ![]() |

Is this the Cuda 2.3 version? No, you wouldn't see it in BOINC if CUDA_V2.2 or CUDA_V2.3 installed. Please have again a small look in my profile. There is well described where to DL, unzip and where to copy/insert. Ahh.. for the moment, if you have 191.x and it's well you could stay with this driver. Maybe in future you could make a test with 190.x . BTW. Because of the GFLOPS. You OCed only one GPU chip per GTX295, or only one whole GTX295 ? ____________ [Optimized project applications, for to increase your PC performance (double RAC)!][Overview of abbreviations, which are used often in forum and their meaning.] ![]() |

My cards give 84C Max at 21C ambient. Unless you have the older 2 PCB cards, over 90 is bit high. The cards tend to warm up each other. And for the driver, I haven't been able to get a real stable system with Win 7 yet. Hope the next driver is better. TThrottle Control your temperatures. BoincTasks The best way to view BOINC.

Keep a close look at them I send 3 of them back with calculation problems. Lucky me I only got new ones left, they are at least 10C cooler. The 2 pcb versions probably get too hot and therefore tend to make calculation errors. Keep a close watch if you see a lot of inconclusive or errors. Normally there is a fast and hassle free return policy, because they know these card give lots of problems. I got mine replaced with a new one within a week. TThrottle Control your temperatures.

345 wu's done overnite. about two thirds had calculation errors. And I'll bet they were all from the same GPU? (Probably GPU#2) F. ![]() |

345 wu's done overnite. about two thirds had calculation errors. The best would be to set the fan to 100 %. Yes I know, much noise - but.. And not to OC. Look how they work. If they make no errors.. Then if you like, you could OC again - but maybe only little. BTW. The info in BOINC say that the current installed driver support CUDA_V2.3 (2030). Not that you have CUDA_V2.3 installed. For example if you would have 195.x installed BOINC would say CUDA_3.0 (3000). ____________ [Optimized project applications, for to increase your PC performance (double RAC)!][Overview of abbreviations, which are used often in forum and their meaning.] ![]() |

My 295 cards gives 100% at about 85C on automatic. Some of the older cards don't have the fan on automatic but at a default value that is way too low for Cuda use. But the new cards only get that hot when they are close to another card. Normally the temp is 65C. And again expect problems because of the known bugs in the Win 7 driver with the two 295. .... of course less points than with XP 64 TThrottle Control your temperatures.

I tried that with BFG, BFG sent Me mine back or at least another of the old 2 board 295 models... You didn't wrote down the serialnumber of you GPU? ![]() I hope I'll never need to send back a GPU (because of CUDA errors), but I would write down for remember - for to be sure what they had done.

345 wu's done overnite. about two thirds had calculation errors. Thank you again! You been saying 100% fan and finally got it done. Two were at 25% and the other two were at 40%. A little noisier but ok. The driver still 'stopped responding but has recovered' but i'm just glad the fans are working at 100%. Temps are staying in the mid 70's now. And this computer only crunches...except for getting help here! |

And this computer only crunches...except for getting help here! You're welcome! Two fans? A GTX295 have only one fan, or? What you mean with 'stopped responding but has recovered'? I don't know this, never had. A driver crash? There is also nVIDIA_driver_195.81_BETA out there, this will maybe solve this prob? But BETA isn't final, so it could have BUGs. Where to DL.. 'Message 962400' in this thread. The international DL site is still broken. The german work. I see a lot of errors on your PC: 'hostid=5168831/errors' -> Incorrect function. (0x1) - exit code 1 (0x1) This is because of overheat, or damaged chip or RAM? Fred W mentioned, maybe they come from GPU#2. He had also probs with his GTX295. Maybe switch off the OC and look if the errors will continue. They run now at 1282 MHz shader? Normally is 576/1242/999 (core/shader/RAM) AFAIK for the 2x PCB. ____________ [Optimized project applications, for to increase your PC performance (double RAC)!][Overview of abbreviations, which are used often in forum and their meaning.] ![]() |

Even though windows recovers a restart is a good thing to do. Your machine should be a screamer. Insomnia sucks. Official Abuser of Boinc Buttons... And no good credit hound! ![]() |

I, too, am confused about the number of fans - the GTX295 has but one fan and needs it set at 100% for crunching (at least on the older 2-PCB cards). @Sutaru - 'stopped responding but has recovered' is what Vista and Win7 give in the event of a driver crash. Improvement on the XP crash of the machine. @Jon - Having looked through a good few of your error results, they are being produced by ALL the GPU's. I would suggest removing the overclock of the GPU's and running MemtestG80 (available here) to check the memory on your GPUs. F. ![]() |

Don't be confused, nVidia performance tool reports only one fan. And unless they've hidden one there is only one. I've seen both types. The newer (1 Pcb) cards are below 50% fan on automatic, they are way, way cooler. Only when you put 2 or more next to each other, they get pretty hot. TThrottle Control your temperatures.

I thought I had the oc off. all were at 576/1242/999 last nite. this morning the oc was back. i use Rivatuner for the oc'ing and checking the fan speed. Something i did must be wrong. your right, only one fan per card. I running MemtestG80 after this. thank you all. |
