Post: 100,000,000 would surely be a nice round number, but unfortunately it's out of reach for me. Even if I pour all my available resources into this project, I'd probably not even reach 90 millions - there's just not enough time. But in the end it doesn't really matter, every single credit I earn between now and the project's hibernation is still a contribution to the project, and that's the only thing that counts. |

SETI@home hibernation
(Message 2036084)
Posted 5 Mar 2020 by Helsionium
Post: While I am somewhat surprised and even a little bit sad about this news, I fully understand the decision given the need to properly analyze all the data we have crunched for all these years. For the remainder of this month, I will try to prioritise SETI@home over other BOINC projects and even private usage of my devices in order to contribute as much as possible. Let's hope the backend analysis will lead to some awesome discoveries. I just want you to know that if the project ever returns from hibernation, I'll be back! Maybe you should, however, lift the RAC restriction on posting here, perhaps by replacing it with some (low) minimum total credit. |

Post: Hi there, I just retired my old PC after more than 7 years of near-continuous crunching duty. I want to use my new laptop as its replacement, but first I have a few questions since I haven't been following the project news the past two years or so. I have installed the optimised apps from the Lunatics Installer, version 0.45b6 on my laptop. I selected the OpenCL application version for the Nvidia GPU and don't intend to use the CPU or Intel GPU for crunching. I tried changing the <count> to 0.5, but that significantly slowed down crunching, so I went back to 1. Am I using the most recent optimised app and the best settings to get the most out of my GPU? |

Post: When it comes to crunching, 5% becomes 'substantial over time. A more modern mobo with 2x PCIe x16 slots wouldn't mean all that much $$$ in the greater scheme of your build, imho. True, but in the end I don't expect my GTX 680 to last very long anyway, and I won't replace it when it finally fails. However, it has proven remarkably reliable - it has outlived 4 (!) GTX 560 Tis and now also my GTX 660. |

Post: As far as I can see, the motherboard has only one 1x PCIE-slot that runs at x16 ? Yes, and another one at x4. According to a graph in this article, there is no substantial downside to running a GTX 680 in a PCIe 3.0 x4 slot: http://www.tomshardware.co.uk/forum/386054-33-would-pcie-slot-bottleneck |

Post: He could do 2 sticks of 8GB and if he finds in the future your processing for work needs more he can add 2 more sticks of 8 GB later After reading through all your replies, I think that's what I'll do. If I really need it, I can add more RAM at any time. |

Post: OK, so I did a little research on dual channel RAM and it seems that one way to get a viable 24 GB solution would be: 2 of these: (2 x 8 GB) https://playit.de/crucial-ballistix-sport-lt-udimm-8gb-ddr4-2400-cl16.html and this dual channel kit (2 x 4 GB): https://www.cyberport.at/form/?DEEP=2410-16U&APID=294&STOREID=7 If installed correctly (12 GB in one channel and 12 GB in the other), this should give full speed across all of the 24 GB, right? |

Post: U´ll be need a 2xx chipset mainboard , because there is a need of flashing the newest bios to a 1xx chipset mainboard, caused by choosing Kaby Lake CPU.I guess the company assembling the machine will do this for me in that case - they probably couldn't even test whether it works otherwise? Unless he really does need the 32 GB for the video encoding he says he will use the computer for also. I have no knowledge of whether that is true since I don't do any video editing or encoding. Anyone with direct experience with video editing or encoding want to chime in and educate me?32 GB is definetely overkill, but 16 GB might just be barely enough for some of my needs. That's why I thought of 24 GB instead, but I don't know whether using 3 RAM modules instead of 2 or 4 is a good idea. |

Post: Hi guys! After almost 4 years of continuous service, my GTX 660 died, and as a result I'm now going to replace my almost 6 years old main machine. Problem is, I haven't been following the hardware business for years - so I thought I might as well ask some experts. I have already decided on the key features: - MB: Gigabyte GA-Z170-HD3P - CPU: i7-7700K CPU @ 4 x 4,20 GHz - GPU: Manli GeForce GTX 1080, 8GB GDDR5 - RAM: 24 or 32 GB - OS: Windows 10 Pro x64 - The machine will be used for crunching, programming and occasional HD or even 4K video editing. - My old GTX 680, which is still working, should be used in the new machine as well. - I don't intend to do try any overclocking this time around. However, I slightly overran the budget I'm willing to spend, so I need your help with some adjustments: First, RAM: The shop allows me to decide between these three options: 4x Crucial DIMM 8GB, DDR4-2133, CL15 (€ 240) 4x Crucial Ballistix Sport LT UDIMM 8GB, DDR4-2400, CL16 (€ 276) 4x 8GB Kingston HyperX Fury, DDR4-2400, CL15-15-15 (€ 300) Is the difference between DDR4-2133 and DDR4-2400 big enough to warrant a 15%/25% price increase, especially for my intended uses? 24 GB (3 x 8 GB) of RAM would be enough for me. Is there any downside to using an "odd" number of RAM modules (or a total RAM size that's not a power of 2)? Second, CPU cooler: The shop I want to buy from provides a "default cooler" at no additional cost, but unfortunately doesn't specify what the default cooler is. Apart from that, the shop gives me several options to choose from: LC-Power Cosmo Cool LC-CC-95 (€ 20) Scythe Katana 4 (€ 30) Alpenföhn Ben Nevis (€ 35) be quiet! Pure Rock (€ 40) Water cooling solution Enermax Liqmax II 120 incl. assembly (€ 95) Do I really need a cooler different from the "default cooler"? Thank you in advance! |

Post: I don't really understand what's going on, I got this error once, but the subsequent requests succeeded. I didn't do a thing between these requests. So for now it's working fine again, but I'm interested what could cause that behaviour? Shouldn't this error be persistent? Here's the log of the last BOINC client session: 03.07.2013 21:45:13 | | No config file found - using defaults |

Post: Hello, a short time ago (few hours maybe) I started to experience errors I din't have before. All of a sudden, I get "Your app_info.xml doesn't have a usable version of Seti@home v7" - I have installed the latest Lunatics optimized apps, already tried uninstall/reinstall and detach/reattach. The app_info.xml looks normal, it's the same as it was before (working fine ever since v7 was released). At the same time I noticed all GPU WUs had errored out, with the error message "Can't link app version file". Today, I installed a new GPU (GTX 660 in addition to the 680 I already had) and updated to the latest stable drivers, but I doubt it's related, as it worked fine for a few hours after that. If you need more info, just state what you need. Your help is very much appreciated. |

Post: I'm using x41zc_cuda50 and the AP nVidia OpenCL application on my only machine (GTX 560 Ti + GTX 660) so my results aren't entirely comparable with your situation, but here's what I found out: - Running 3 WUs is possible, but it's not worth it. The GPUs are maxed out with just 2 WUs anyway. With 3 WUs, there was somewhat higher power usage and temperature and occasional slowdowns. There was no noticeable positive effect on processsing throughput. - With 2 WUs some moderately GPU-intensive programs still work without major problems (e.g. Google Earth, HD video), but with 3 WUs they wouldn't, even if there was still enough VRAM free. - If any CPU-intensive task runs at the same or higher priority than the GPU tasks, this can cause massive slowdown. So I run the GPU tasks in high priority AND make sure no other CPU-intesive tasks run in high priority. But keep in mind that this (except that last point) might be different when using x41g. |

CUDA problems (Lunatics) / zero status but no finished file
(Message 1343195)
Posted 5 Mar 2013 by Helsionium
Post: Sorry for resurrecting this old thread, but I want to note that the problem has finally been solved. My card, the "Zotac Geforce GTX 660 Ti AMP! Edition" is factory-OC'ed to 1150 MHz core and 1650 MHz memory clock - voltage already maxed. The solution was to reduce the memory clock to 1500 MHz. It's running fine for days now (at core frequency 1200 MHz). Any higher value, particularly 1530 MHz and up, caused the driver to occasionally crash (with x41zc_cuda50; the previous x41g only caused the "zero status..." problem but no driver crashes) and whenever the driver crashed, the clock frequencies would be reset to factory and constant crashes (every 20 seconds or so) would happen from that point on. I didn't notice this solution earlier because I never thought I had to decrease memory speed by that much. Anyway, it's fine now. Thank you, jason_gee, for all your help. Kind regards, Helsionium |

Post: OK, just to be sure, since I don't have any experience with the GTX 660 - the current core voltage is 1.175 V, core clock 1163 MHz, memory clock 1652 MHz, temperature 58-60°C. Is it safe to increase the voltage and what amount would you suggest? |

Post: So, some new observations: - Enabling hyperthreading didn't fix or reduce the errors, I still left it on anyways. - The error rate seems to be lower with x41g so I reverted back. Might be a coincidence, but at the very least, x41zb is certainly not better in that regard. - Number of tasks per card doesn't matter. I ran only one task per card over the whole night as opposed to my standard two, but the error rate was not reduced. - I swapped the cards, the error still only affects the 660. - A temperature issue can now definitely be ruled out, after swapping the cards, the 660 runs at a temperature of 58-61°C. Also, I didn't find the SLI option to disable it. I didn't connect the cards with an SLI bridge, so it shouldn't be available, right? |
