TT Throttle for CPU does NOT reset to the last checkpoint as the tasks stay in memory.
-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of S Ross Sent: Thursday, January 17, 2013 8:57 AM To: Ed A; Charles Elliott Cc: BOINC Developers Mailing List; BOINC Alpha list Subject: Re: [boinc_alpha] [boinc_dev] "anonymous GPU" feature Using a throttling tool is the wrong solution. You can better control the GPU's temperature using tools such as EVGA Precision or MSI Afterburner. On-off, on-off GPU crunching is Extremely Bad for performance; tasks revert to their last checkpoint and the GPU clock will be increased and decreased repeatedly (unless is stalls). If projects run too hot, increase the fan speed, reduce the Memory frequency, downclock the GPU and/or the CPU. You can even under Volt the CPU and GPU. TThrottle is also a poor solution to CPU temperature control, for the same reasons. It's better to adjust the number of cores to crunch on, the CPU's clock speeds and Voltages. Adding a case fan or two might also help! ________________________________ From: Ed A <[email protected]> To: Charles Elliott <[email protected]> Cc: BOINC Developers Mailing List <[email protected]>; BOINC Alpha list <[email protected]> Sent: Sunday, 13 January 2013, 17:53 Subject: Re: [boinc_alpha] [boinc_dev] "anonymous GPU" feature > One of the best ways to control GPU temperature is by using Nvidia's Performance tool TThrottle by eFMer controls CPUs, ATI/AMD & NVIDIA GPUs quite effectively. Individual temps are set for CPU and GPU(s) and the control works well.
