1) Message boards : BOINC client : CPU power usage (Message 4658) Posted 5 Jun 2006 by stuartd Post: Thanks! I see my measurements are right in line with the "Energy considerations" page -- I hadn't seen that before. Do other processors have similar costs? (Well, I guess with everyone going to Intel, maybe it's moot.) Other interesting numbers -- I find my fridge costs about 45 cents a day, and when my computer is powered down but everything else still "on" (monitor sleeping, powered speakers still powered but quiet, cell phone and PDA chargers plugged in but not charging, etc.) the plug strip is pulling about 7 watts -- not bad. Energy considerations. There was a thread on the Seti number cruncher board in the middle of last month discussing this but I don't have the time at the moment to locate it.

2) Message boards : BOINC client : CPU power usage (Message 4652) Posted 5 Jun 2006 by stuartd Post: I just got a watt meter ("Kill-a-Watt" model P3, about $20 online), and I was wondering how much power my computer actually used. I discovered that running BOINC (as opposed to just idle) increases the PC power consumption by ~50 Watts. This is a 2.8GHz "hyper threaded" Pentium, Windows XP, lots of RAM. This amounts to ~10 cents a day (assuming about 20 hours a day of run time -- I turn the darned thing off at night), or $36.50 a year, at PG&E's consumer rate of about 10 cents a KWh. So, donating "unused" computer power is actually donating real electrical power -- at least on this computer. Has anyone else done measurements? What sort of values are you all seeing? Happy trails, Stuart
