It is not a case of running 6 or 12. Try running 9 (75%) first and see if that runs continuously. If that works try to up it to 10 (83.3%) or if it doesn't then 8 (66.7%)
Adjust until you get continuous running. Mike |

If you are running on Windows and have concerns about high temperatures, then use Tthrottle. This program reduces the CPU cycles that BOINC calculations are allowed to use thus keeping the temperature under control.
The maximum temperature you consider 'safe' can be manually set. I set the maximum temperature for my Ryzen 5 3600 as 79 deg C even though the AMD thermal limit is 95 deg C. For Tthrottle to access the CPU temperature on an AMD chip you also have to run the 32 bit portable version of HWinfo. This is true even for a 64 bit CPU and operating system. |

How did you get 79 deg C as a safe temp? Mine is not above that but am still interested to know.

@AgrFan On multiprocessors, at most use: 6 processors On multiprocessors, use: 100% of processors Options/Computing preferences Use at most 50 % of CPUs Use at most 100% of CPU time I have a i7-2600 Dell Optiplex (4C/8T, 4 units) and a Dell Inspiron i5-3330 (4C/4T, 2 units) set to 50% in Boinc Manager to keep the heat down. Please Note WCG?: I did try repeatedly setting it to On multiprocessors, at most use: 6 processors here on the website & nothing changed, it kept running 12 WU's. Setting On multiprocessors, use: 100% of processors to 50% reduced it to 6 WU's  Must be something needs updating here on the website with these newer hyper-threading thingamajigs  For whatever its worth I prefer/ed using the website for my settings just because you set it once & forget it, unless you get a new CPU or whatever I forgot to mention am currently using Ubuntu, I finally Escaped Windows  a couple years ago  Again, thx for your replies its all just a matter of learning how to set things up for the new laptop after so many years with PC |

@BobbyB
My usage of 79 deg C is not from any knowledge. I reasoned that if AMD consider 95 as its upper limit, 80 should be safer. I then reduced it 1 degree further so that the line on the graph is separate from the major grid line of 80 deg C in the Tthrottle display. |

Reducing the core count by half won't reduce heat much on a hyperthreaded CPU because all the logical cores are still 100% active, you are just reducing the extra threads. The best way to maximize crunching efficiency and reducing heat would be to somehow reduce the CPU core clock speed.
Asus laptops can do this through their App "Armory Crate" which will let you fine tune exactly how much power you want your CPU to consume. Reduce power & clock speed = reduced heat. The heat is what's causing your laptop to shut down most likely. As a general rule I like to keep core temps below about 80c for longer term reliability. Some stock CPU's will run up to 95-100 C unchecked, which is way too hot in my opinion. Also if you are savvy enough to clean the fans/grill of the laptop which may be covered in dust this would also help with your thermals. To do it best would require taking the bottom panel off the laptop and cleaning with compressed air and the like. Also, some laptops have settings in their BIOS for power states that you can set which could also help. Best of luck. |

I just ran an experiment using Boincmgr on a 3900x.
----------------------------------------100% CPU 100% TIME Tctl: +73.8°C 100% CPU 50% TIME Tctl: +64.2°C 50% CPU 100% TIME Tctl: +64.0°C Did the same for a 3600x 100% CPU 100% TIME Tctl: +69.9°C 100% CPU 50% TIME Tctl: +60.9°C 50% CPU 100% TIME Tctl: +60.4°C I did play around in the BIOS for both the 3900x and 3600x but don't remember the details. Edited: Found it. Suggested by flynryan I imagine you get finer tuning with CPU Time.https://www.worldcommunitygrid.org/forums/wcg/viewpostinthread?post=653728 TL;DR I changed BCLK Frequency from 100.00 to 98.00 then the "AI" up'ed the Mhz and lowered the volts. It's almost contradictory. Temp went to 70-72 instead of 76-79 Agreed on the dusting part. Dust is the enemy. @ca05065 Ah! You did what I did. Played it by ear. Did not know any of this when I started in 2020 so I did overkill: threw a massive Cooler Master fan at it.[Edit 1 times, last edit by BobbyB at Nov 27, 2023 5:36:56 PM] |

@BobbyB
am going to Try(can be tricky on Linux getting BOINC running properly, finally found a CPU Temperature GUI to use & thats all GTG) getting BOINC up & running tonight then start experimenting will let yas know |

can be tricky on Linux getting BOINC running properly Don't understand this part. I installed 3 and not even 1 problem.BTW what's wrong with setting the CPU time method using BoincMgr? The temp info above was done with sensors command that came with my version of Ubuntu Agreed about the tools to fiddle the Bios settings are only Windows.
