Post: No need to fingerpoint etc. So monitor attached seems like one common attribute. TBar is this behaviour consistent with different drivers?! Linux flavors?! Im running Debian 10. Do you have a checklist so we can pinpoint this behaviour? Perhaps running Gnome vs Kde or anything?! I dont have all variables needed and in the Linux world there are alot. Kernels etc etc. The list is huge. :-/ |

Ok, i just rebooted it. Lets see what happens. I didn't shutdown boinc or anything. systemctl reboot was the command! EDIT: I didn't notice anything weird, only one WU from yesterday?! Do i miss anything? /EDIT[/u] |

Post: Does this host https://setiathome.berkeley.edu/results.php?hostid=8570185 fit in the criteria of the problem? I do not have any monitors attached to it and can only access it through SSH. Does a simple reboot in the console make the problem appear? If so i can test this too. |

Xeon Phi 7120P is it usable for S@H ?

Post: For what it seems there seems to be a UEFI bios, but not fully compliant. Could work though. Quadro P2000 seems to be a Cuda 6.1 so it would work better in Linux. Run TBars all_in_one package aswell and your system should fly! |

Post: Exactly, most bang 4 buck = Nvidia 1660TI or Super. Uefi Motherboard is required because all those new GPUs require UEFI support in bios to get detected properly. |

Post: It's obsolete these days. https://ark.intel.com/content/www/us/en/ark/products/75799/intel-xeon-phi-coprocessor-7120p-16gb-1-238-ghz-61-core.html Only 16G ram, 61 cores @ 1.2Ghz! I think a 3700X is faster than that Phi board. 16 * 3800Mhz is around 60000 Mhz roughly the same and then you've got FPU enhancements and it's pipeline. |

Really dinky or old cpu models driving "huge" gpus....
(Message 2017549)
Posted 2 Nov 2019 by -= Vyper =-
Post: I think this computer fits that category. A dual core pentium cpu driving 1080ti and a 970. Its cpu starved and im doing alot of magic in cron to increase thread priority to setiathome executable. If i would exchange that motherboard, cpu etc to a new one the RAC wouldnt increase that much after all. https://setiathome.berkeley.edu/show_host_detail.php?hostid=8676036 |

Post: Its not that you reduce energy but your cpu can produce more for the same amount of energy. But if you only use the cpu to feed the gpus you're soo much better of using the mutex version instead sucking up almost the same cpu wattage and the performance difference would be almost none. Mutex version had helped me alot because i have slower cpu to feed the gpus. In my case running solely s@h on the gpu and as only project its a clear win for me to run mutex and use the cpus as slaves only with almost the same amount of powerusage. |

Post: Cpu crunching is never good efficiencywise for your wallet. The only cpu that comes near is the new Threadripper with 64 cores. But the price is another thing. As usual its almost always better to have a latest gen Nvidia bang/buck wise. Otherwise its always better to have a cpu enough to feed powerrestrained gpus for efficiency. |

Post: Do you feel that there is an advantage with the X470 chipset over the B450 with respect to crunching? Here is a list of motherboards and their capabilities for running Ryzen 3Gen, the page is in Swedish so you might need translate.google.com to make it understandable. https://www.sweclockers.com/forum/post/17951749 |

Post: Question for @Vyper, which of the cpu temp sensor readouts do you use? The motherboard SIO CPU Temp or the cpu internal Tdie temp? The motherboard CPU temp is only polled every couple of seconds and is an average over time. It only reports whole integers and the accuracy is limited by the LSB conversion of the ADC. I was testing with prime in Torture mode.. Small FFTs maximum heat. The software reports the Tdie and it's around 69 degrees Celsius, got a sporadic peak to 78 degrees Celsius and i could hear the fans rev and then it was back to 68-69 degrees C again with low noise. |

Post: Running without SMT certainly explains it. But at the cost of about 50% or more potential performance. Yea, around 40% in multithreaded applications, but with higher performance in some single threaded applications instead. |

Post: I'm doing about the same. Auto, drop vcore offset to -0.05 and a Noctua fan U14S, but i've disabled SMT. I do not need the extra 12 cores. I just want as full speed on the single threading as possible as it is powerful enough. My cpu @ 24 cores = 70xx Cinebench and the cpu @ 12 cores = 50xx Cinebench. The cpu is almost always below 70 degrees Celsius (Except with prime95) and turbos up to 4.5 - 4.6 region on one core as intended. Running the ABBA bios. Cannot really hear the fan as it's dead silent and i've adjusted fancurves in the bios that it doesn't throttle until 70 degrees Celsius.. Its so silent even at 100% usage. |
