Set to run 50% CPUs and 100% of CPU time in BOINC local preferences. 15 years old. ;-) Should work, it works perfectly on my Sandy Bridge laptop and an Ivy Bridge Desktop, which I use sometimes, they are not that much newer.running 50% of CPUs means running one WU on each core Don't think this is happening on this old Intel Core i5 CPU M 540 CPU about 25 years old. However, when I set affinity to force a WU process per Core then the two Core temperatures were exactly the same most of the time, and only deviated by 1 or 2 °C briefly at times. This is the correct behaviour and indicates, that Windows didn't recognize the CPU right and didn't balance the load properly. That makes a discussion based on obsevations on this system of course pointless. |

I've always run mine at 100%. In order to minimize any impact on your use, you can always set BOINC to suspend when in use. As long as you're not overclocking and are operating within specs, then chips don't wear out. It's only the fans and drives you need to worry about, and those generally last a very long time. I'll be performing a long overdue upgrade on my workstation this weekend. This hardware has been running for... 14 years.
----------------------------------------The exception to this would be laptops. They are not not designed to be under continuous full load. For those, I would reduce the load until the fans and heat are at a reasonable level.

They are not not designed to be under continuous full load. This applies actually to most prebuild systems, even many expensive ones.[Edit 1 times, last edit by Link64 at Aug 6, 2025 2:43:17 PM] |
