How to cool an Intel Core i9 13900K processor

Post: In case anybody else has Intel i9 cooling issues I have sorted out why my PC was running so hot. Turns out it was due to the "bending issue". I took the PC apart installed one of these http://thermalright.com/product/lga1700-bcf-black/ put everything back togther and Intel Extreme Tuning Utility benchmark has gone up from mid 10,000s to high 13,000s and CPU temperature is well under control. I am a happy bunny. |

Post: Maybe, I did look into this when buying all the parts. Only the thermal grizzly solution had any kind of torque setting. The rest just used normal screw tighening and the results on the web were often worse when using a replacement clamp. I think because they did not use the correct torque. |

Post: It's raining here so had time to play with the BIOS settings. Setting long duration power does reduce the CPU package temperature which is good news. Overall I am wondering if I should get a better CPU cooler although I doubt a better air cooler would give me much more improvement. I don't have spae in the case for a water cooler so that is kind of ruled out. * Update * I found a setting that by default used ASUS overides, I set this to enforce defaults and that is sufficient to keep temps around 80-90 when under load. I think the motherboard by default was providing lots of power. Seems better way for a novice overclocker like me to manage the temps. My new PC is still 350% faster than my old one so short of spending a lot on better cooling this looks the best option. |

Post: Thanks for the info. One thing I was going to do was remove the cooler and redo the thermal paste, not expecting it to help, but need to do that to eliminate this as a cause. Pretty sure I removed the film from the base of the cooler as I clean the processor and cooler surfaces, but will check when I redo the thermal paste. How would I limit the power usage? I have tried this in the UEFI / BIOS: Global SVID > offset mode -ve > offset voltage 0.5. Intel Extreme Tuning app with stress test now shows Core package temp at 96 degrees Celius and Power Limit Throttling turns red rather than Thermal Throttling turning red. A -ve 0.25 was minimum BIOS would allow and had no effect. - 0.5 gets the CPU package temp just below 100 is this the besy way to limit the power? Motherboard is an ASUS Intel Z790 ProArt Creator |

Post: Hi I have built a new PC around an Intel Core i9 13900K processor. I am having issues with keeping it cool at 100% load. Using Intel Extreme tuning Utility I can get graphs of package temp, CPU utilization and Max Core Frequency. Running the stress test CPU utilization reachs 100% but the Max Core Frequency is reduced when the temp hits 100 degrees celius. Currently using a Noctua NH-D12L Dual Tower cooler with dual fans which according to Noctura's web site is compatible with the Intel Core i9 13900K, but my results show it does not keep below the temperature at which the CPU is thermal throlled. Any advice welcome. |

Post: Things look a little odd for my Astropulse work units. In the tasks list for all my Astropulse WUs whether in progress or waiting for validation if I click on the work unit link I get: can't find workunit But for Seti@home the work unit links work, just fails for Astropulse WUs. Anybody else seeing this or know what is the cause? |

Post: I have several Astropulse workunits in my queue listed in BOINC manager. However, if I follow the tasks list on the web page it only lists Seti@home work units, it shows 0 for queued Astropulse. Been like that for several hours now, is the web site not being updated or is something amiss? |

Post: With the news that Seti@home is going into hibernation at the end of the month what personal crunching target would you like to reach before the last work unit is validated? I switched from Seti@home classic to BOINC when I reach 6,000 classic workunits as it was a nice round number. I have crunched Seti@home on BOINC on and off over the years so wondered if I should set a target of 5,000,000 total credit. Would be a strecth target for me to reach in March. Debating if it is worth the electricty bill! |

Post: It was sad to read the news that the crunching has to come to an end, there was so much to look forward to in the future with Parkes data etc. Beat wishes for the analysis side, hopefully the hibernation is not too deep and crunching can start again in the future. |

Post: What are the odds to get two Astropulse workunits and have the same wingman for both of them? Yes, thanks. I have been validated for one of the two WUs now so fingers crossed for the second one. |

Post: What are the odds to get two Astropulse workunits and have the same wingman for both of them? I noticed as both are flagged as inclusive https://setiathome.berkeley.edu/workunit.php?wuid=3652425865 https://setiathome.berkeley.edu/workunit.php?wuid=3652425907 If the quorum work unit goes to the wingman will I see this flagged as invalid or error in my stats? |

Post: I only run SETI@home once in a while now so pleased to see some Astropulse in my recent run.The current split is, ap_09se19aa, "ap" = AstroPulse, "09" = 9th, "se" = September & "19" = 2019. ;-) Ah my mistake - thanks so new data :-) |

Post: I only run SETI@home once in a while now so pleased to see some Astropulse in my recent run. As these are from April 2009 are they: 1) A rerun of previous data? 2) Old data not sent out before? 3) Data run before but now being re-run with new processing algorithms? |

Post: I sometimes see in the server status page multibeam done but astropulse still being split for a tape. (sometimes the tape is in this state for several days). Is this a true representation i.e. Astropulse workunits are still being generated or is it some bug in the status page leaving them in this state? There is one in the this sate right now, multi beam done Astropulse still splitting according to the server status page. This is a problem with the file or the splitters or has multibeam finish before Astropulse? |

Missing GPU, waiting to run
(Message 1932529)
Posted 28 Apr 2018 by David@home
Post: Another item that can cause missing graphics coprocessor is using fast user switching on a Windows system with multiple user accounts. If you have such a setup make such BOINC is shutdown down on the active user account before switching user accounts. |

Post: Getting messages in the event log I have never seen before: The good news is that the four work units I had stuck in download did eventually download. The bad news is that now on my tasks web page I have four more WU in progress than I have in the cache on my PC. Any suggestions how I can clean this up please? |
