I recall one discussion here finding that HT threads could drive the GPU while all cores were busy with LLR. The cooler still had life left when I put in a new mobo with i7-5820K but of course the cooler wasn't compatible.
#BOINC FOR LINUX FULL#
The stock CPU fan wasn't cutting it with CPU temps peaking at just above 100 C while doing LLR full tilt with a slight O/C, whenever the house's air conditioning wasn't blowing into the case. My i7-920/mobo finally kicked the bucket 2.5 years ago after running hard for about 6 years. I noticed I was getting occasional invalid LLR results until I cranked up the CPU fan speed to 100% in the BIOS. You can get to that setting by going to.Boinc Manager, options, computing preferences, the computing tab and change the very top box to 99 and click ok at the bottom to save the change.
Essentially that means that I use one less cpu core crunching than the pc has, so on my 6 core pc's only 5 are being used, 4 for my cpu workunits and 1 for my gpu workunit with whatever cpu allocation it needs. Windows is the same way, that's one of the reasons why I set all of my pc's to only use 99% of the cpu cores, it frees one for doing anything else and keeps the pc from getting too hot too. In throughput terms, running 2 PPS sieve tasks simultaneously on a GTX 760 shaves one minute off the average runtime, so it's not something I'll do unless the machine runs unattended.
I find that on Linux, any version of BOINC, having BOINC Manager open while the GPU is saturated adds just that extra bit of lag to make doing anything with the mouse completely intolerable, as opposed to just slightly intolerable.
