1) Questions and Answers : Windows : install in a corporate environment (Message 96430) Posted 13 May 2020 by vince Post: I was running @4ghz. running at 6 cores, 35% usage, my cpu was between 53c (during the day) and 46c (at night) anything above 50% cpu usage for six cores made it go over 60c. 100% cpu made it go over 70c I'd be interested to know what "pretty good cooling"is. Is it liquid cooled? I was reading one article that said a guy achieved 56c while running at full tilt only after adding a liquid cooler.
2) Questions and Answers : Unix/Linux : possible bug in Computing preferences -> use at most X% of CPU time. (Message 96386) Posted 12 May 2020 by vince Post: I am currently having to throttle CPU usage to keep temperatures down. (I have another thread open on the temp problem and wont bore you with that). So, I have been tinkering for days with max CPU frequency at the hardware level, number of cores, percentage, etc. For reference CPU is FX8350 8 cores, 1 thread per core, 4 ghz. Since this is my work desktop, I want to try and keep the max frequency at 4ghz so I while working it's nice and responsive. A while ago I found that running 6 cores at 45% of the time was a sweet spot. Everything was at most points, and lowest overall temp. Today I found that when I specify 45%, the average CPU that it was actually using was around 6%. If I changed it to 35% then usage was a steady 35% If I changed it to 50% then usage was a steady 50% change it to 45% and it's back down to a steady 6% Very odd. Has anyone else reported this? My current workaround is to run 2 cores at full tilt.
3) Questions and Answers : Windows : install in a corporate environment (Message 96384) Posted 12 May 2020 by vince Post: so yes definitely a physical problem. The inside got cleaned. I added an case fan, as per what google wisdom I could find. (suck in at the front and out at the back). Made a small difference. Then added 2 side panel fans, to draw more air into the case, which seemed to be conventional wisdom. Made it hotter! So reversed the fans and I got a 10c cooling over all. A bit better. Plus it'll keep my feet warm in winter :-) Isopropyl alcohol and MX4 thermal paste on order. Once they arrive and I've re-seated the cooler then I'll report back. I did find another issue with CPU throttling that looks like a bug, but I'll report that separately. Many thanks for your advice so far.
4) Questions and Answers : Windows : install in a corporate environment (Message 96281) Posted 8 May 2020 by vince Post: thanks for the feedback. It is a new PSU and CPU cooler and so I hope they are good, but'll I'll give that a go. Anything else I should check? I can see all the fans running okay.
5) Questions and Answers : Windows : install in a corporate environment (Message 96199) Posted 7 May 2020 by vince Post: just in case anyone continues reading this thread. So in terms of getting permission - of the three companies I've spoken to who are interested, it seems that security and cost are currently the issues. Mostly security, although there is plenty of stuff on the web to show it is secure, so hopefully it'll get past that. Then there's the cost of running it. Nothing is for free. Compute costs electricity at the very least. I'm going to have to work on that one. The biggest issue I personally have come across so far is heat. After trying various throttling options in the BOINC manager, running fewer CPUs, running them at different percentages, etc, the best way I've found of keeping the CPU temperature at a reasonable level (ie below the 60c "high" for my particular processor - 8 core 4 ghz AMD FX8350) while keeping the processes delivering the maximum benefit is to throttle the CPUs at the hardware level. Now I can do this since most of my time my PC is not doing a lot computationally, and I don't mind waiting a few seconds for my browser to load all the tabs at the start. However, not sure that would be a runner for most people. I found that running all 8 cores at 100% in BOINC manager (but throttling CPU down from 4ghz to 2.1 ghz at the hardware level) runs the machine at 52c Whereas running 4 cores at anything more than 40% in BOINC manager (but with the CPU not hardware throttled, so max of 4ghz) takes it over 60c Even running 1 single core at 100% in BOINC manager and CPU not hardware throttled takes it over the 60c. Worse still, if I run the cores throttled at 40% in BOINC, the timescales are so long to I may not complete work units in time unless my computer is on 24/7. And even then maybe not. That I'm sure will be the next issue I face in terms of getting it through corporate will I'm sure be heat. It's noticeable, physically. I welcome any suggestions.
6) Questions and Answers : Windows : install in a corporate environment (Message 96113) Posted 5 May 2020 by vince Post: excellent advice, esp re reduced computing power. I've only just started using Rosetta at home, up till now I've been using folding at home, and one thing that bugs me about F&H is the lack of control over the CPU use. BOINC does seem to be much more friendly and configurable in this regard. In general, would one be better to use (say) 1 core at 100% usage rather than (say) 4 cores each at 25% usage? Do you have a feel for which of those options might be better in terms of fewer watts used, CPU temperature and work unit completion? I know from experience people don't like it when their laptops get hot.

8) Questions and Answers : Windows : install in a corporate environment (Message 96093) Posted 5 May 2020 by vince Post: Has anyone ever done an install in a corporate environment, so that it gets installed silently? I'm trying to get people to install it in their work environments, and the best way would be to have it done silently in the background like everything else. Has anyone else done this before? Any suggestions on how it might be done, with a default config? Also - same question regarding putting it on servers as well so they can be used in quiet times?
