1.3 Advanced Information
 , has put together a fantastic site to help you compare average WU completion times under many different configurations. The site can be found here. got feedback?by AdamB If you need to change your e-mail address, you must have access to the old account, since this is where SETI will mail your password. If you don't have access to your old account, or you mis-typed your e-mail address when first logging in, you will have to sign-up again as a new user with the correct e-mail address. got feedback?by samburgers http://www.geocities.com/lwddemon/setiservice/ One of our members, pike, has also made a simple tutorial that you can follow here: /forum/remark,2843724~mode=flat got feedback?by Liontaur got feedback?by 72245156 1. Go to Start > Control Panel > Scheduled Tasks > Add Scheduled Task > 2. The Wizard GUI will come up. Click > Next > Browse > Look for the .exe you want to run: i.e.: setiathome3.03.i386winntcmdline.exe or SetiSpy.exe or SETI Driver.exe (You can run all at the same time as well, following the same steps for each .exe). 3. Click "Open" > (follow the wizard directions and enter your regular Windows login password > 4. When it asks if you want to review "Advanced Settings" (or anything similarly worded) after the Wizard finishes, check "Yes." 5. Open the "Schedule" tab > 6. In the Scheduled Tasks drop down window > choose "At System Startup" > click "Apply" > 7. Open the "Settings" tab > UNCHECK "Stop the task if it runs for ..." > click "Apply." 8. Uncheck everything under the "Settings" tab except under "Power Management." 9. There should be checks next to "Don't start the task ... batteries" and "Stop the task ... batteries." 10. Click OK and you are on your way. Seti takes over from there, and will start running as soon as you reboot. 11. To open SETI Driver or SetiSpy, go to Start > Explore > and locate the .exe. Click on it, and you will be able to see your progress from there. For a more detailed tutorial, including pictures, please see this thread: /forum/remark,2843724~mode=flat
got feedback?by Sparrow 1) Disable all the POWER MANAGEMENT in BIOS so that PC will not shut down from inactivity or from closing the lid. 2) Set Control Panel, Power Management, Power Schemes Tab, to NEVER shut off Screen or HD in Plugged-In/AC Power mode. 3) Set Control Panel, Power Management, Advanced Tab, Power Buttons, "When I close the lid of my portable computer" to NONE. Now, when you are inactive or close the lid, the computer will not try to shutdown, suspend, or hibernate. (You should remember that if you are accustomed to just shutting the lid). We do NOT recommend shutting the lid of a laptop and letting it run. They can get very hot with the lid shut. There is a small prong above the keyboard that turns off the screen when you shut the lid. Instead of shutting the lid, insert a plastic card, such as a credit card, in the groove below the hinge to depress that prong and shut off the screen, leaving the lid up to keep the machine running cool. Follow these steps and you should have no problem running SETI Spy and SETI Driver with the CLI 24/7 on your Dell laptop. Thanks to Doc olds and Kdanieli
got feedback?by Snakeoil Note, if you change your e-mail with SETI (this doesn't apply if you only change your BBR e-mail), then your SETISpy version 3.0.7 or older will not work correctly, you need to add the following line to your setispy.ini file, BackupEmailAddr="new e-mail address" To change your e-mail with BBR, you need to go to the Preferences page and change it there.
got feedback?by gameboyrom You will be defeating the SETI process if you use a software cooling program (any kind) to try to cool down your system. If your system is getting too hot or even overheating when you run SETI, then there is something wrong with the mechanical cooling of your system and you should look into what changes you can make to your system to cool it down. Running SETI is roughly the same amount of work a busy web server (Like the one here at DSL Reports) would perform day in and day out and they do not overheat when the system is properly designed. You should consider more efficient mechanical means of cooling, since your system would overheat if it was put in a production environment. SETI has pointed out a cooling need that you may have overlooked, that's all. There is nothing wrong with the SETI program and on a efficiently cooled system you will not overheat or run too hot using SETI. Some mechanical means of cooling you could consider, but are not limited to: 1) Increased Case Airflow 2) Artic Silver Thermal paste between all heatsinks and CPU/chipsets 3) Larger/more efficient HSF assembly 4) Peltier Cooling 5) Water Cooling 6) Lowered room Temperatures (A/C cooling) 7) Fans to circulate extra air where your PC is 8) Blowhole fans in the Side of the case and or the Top of the case or Both 9) Taking the side of your case off 10) Asking in the Overclockers Forum here for cooling tips and help 11) Searching the Web for Cooling products, CoolingTips and Cooling Help using a search engine like Google. but stay away from ALL "Software Cooling" unless you are not interested in running SETI.
got feedback?by Doctor Olds Part 1 There has been much discussion about this very topic and there are many who give their opinion, however there is nowhere that gives the facts for potential users to read this information which they can then show to those who may complain about the use of Electricity. Lets start by explaining the simple principles of Electricity and the power consumed. As we all know, electrical circuits consume power (va), one Watt of Electricity is also 1va. Calculating the voltage in a circuit and multiply it by the current used arrives at this figure. Example 1: Circuit A has a supply rated at 12V (Vn) and measurement shows it draws some 4.5A (In) from the supply. To determine the power rating of the circuit you simply multiply the Voltage by the Current thus.. P = Vn * In = 12 * 4.5 = 54 watts or 54va Now we understand that, there is one important point to make at this stage. If you alter the Voltage, you will also alter the current drawn from the circuit, however the power will remain the same at 54va. Example 2: P = Vn * In = 200 * 0.27 = 54 watts or 54 va. If you are wondering about the 0.27, then that is the current drawn from the circuit. As I said, the power must remain constant for the circuit, so by increasing the voltage you are reducing the load taken from the circuit. If you have any doubts about this then do the calculation in reverse. Example 3: In = P / V = 0.27A Part 2: Now we have the basics out of the way, lets go on to the important part of cost. Lets assume you turn your monitor off manually when not in use, so we can just concern ourselves with the actual computer itself. Please bear in mind these are rough figures with regards power used and only as an example. The maths are correct, but the power used by each users machine will depend on the hardware and the setup of the machine. Your computer has a 300W (300Va) PSU and runs at 120V, therefore it will draw some 2.5A from the supply Remember Examples 2 and 3 above. 300 / 120 = 2.5 where 300 is the maximum power of the PSU 120 is your supply Voltage. There are things inherent in all electrical circuits that have a bearing on the actual power used and these are called losses. They occur due to electrical circuits being far from perfect and take the many forms. The average PSU in a computer will operate at about 80% efficiency due to the nature of the circuits employed. This means that for the PSU to deliver 300W (va) as rated then it will actually draw about 375W (375va). Now we have that information, we can begin to look at a more accurate cost running calculation. Whilst we know that your Computer will not run at full PSU load, if ever, we will use the full load to give the MAXIMUM cost that should be seen to any user. Your PSU, as we have shown above, uses 375W (va) of electrical energy from the supply. Therefore to do the cost calculation is rather simple. Example 4: Power used at maximum (Pmax) = 375va So now calculate the total power used in 24 hours, P(max) * 24hrs = 375 * 24 = 9000va or 9000W (9Kva or 9Kw) If you pay, for example, 10 cents for each unit of electricity, then your cost of running the machine is : 9 * 10 = 90c per day If you wish to know the monthly cost, then calculate as follows: 90 * 7 * 4.3 = 2709c or $27.09 per Calendar month. The 4.3 in the above equation is the multiplier required to calculate any figure on a calendar month basis. Now we all know that electricity costs vary across the nation and from supplier to supplier. If you have a look at your last bill, you should see the unit cost of electricity clearly indicated on there. This is the figure you need to use to calculate the approximate cost of running a PC 24/7 for a month. Some of the information at the top of this in Part 1 may seem a little irrelevant to the cost calculation, however that is information that you can use to calculate all sorts of costings if you know the rating of various pieces of equipment. Part 3. Estimates: The following are based on the following figures. That all of the PSU's run at 80% efficiency, about average, and that each Kw/h of electricity will cost $0.06c per Kw/h. Please note that you will need to adjust the calculation for your given tarrif of costs from your electricity supplier. This information will be available on your electricity bill. 235w PSU Assumed maximum demand due to losses. 293w In one calendar month this would consume 211.6632 Kw/h at a cost of 0.06c per Kw/h, the maximum cost is $12.70 300w PSU Assumed maximum demand due to losses. 375w In one calendar month this would consume 270.90 Kw/h at a cost of 0.06c per Kw/h, the maximum cost is $16.25 350w PSU Assumed maximum demand due to losses. 437.5w In one calendar month this would consume 316.050Kw/h at a cost of 0.06c per Kw/h, the maximum cost is $18.96 400w PSU Assumed maximum demand due to losses. 500w In one calendar month this would consume 361.20Kw/h at a cost of 0.06c per Kw/h, the maximum cost is $21.67 450w PSU Assumed maximum demand due to losses. 562.5w In one calendar month this would consume 406.35Kw/h at a cost of 0.06c per Kw/h, the maximum cost is $24.38 500w PSU Assumed maximum demand due to losses. 625w In one calendar month this would consume 451.50Kw/h at a cost of 0.06c per Kw/h, the maximum cost is $27.09 As you can see the costs escalate incrementally as you would expect. These costs do not include the cost of running a monitor, however as this is not on 24 hours a day these costs are minimal, a few extra dollars a month. The figures quoted above are only if the machine is running at maximum potential load at all times. In most cases the machine will probably consume only about 50% of the estimated maximum and thus cost, however this will vary due to hardware differences and usage. The maximum you can use is listed above and is accurate for consumed power, actual cost will vary with supplier costs per Kw/h. Hope this is of help to those whose spouses, partners or parents are concerned about the cost of allowing a machine to run 24/7.
got feedback?This is wrong calculation.
If power supply has 300W it does not mean it will consume it all the time. This is _maximum_ power which PSU can provide. Real consuming will be much less. 2007-10-14 22:13:57 This helps! Thanks for your energy put forth here. 2011-10-03 14:23:14 Watt != VA http://en.wikipedia.org/wiki/Volt-ampere 2009-01-14 15:56:31 Is There any extra cost in curred in powering up the computer and powering down 2009-05-10 18:40:21 The higher power rating of a psu does not mean it will use more power, only it is capable of delivering more IF needed 2010-03-14 17:35:30 You might want to factor in the cost of wear and tear on the computer. Everything is rated for only so many hours of operation. 2010-04-05 15:10:26 I live in mass and my last bill states .0728c per watt, but there is also an additional .05462 included based on fixed transition costs and whatnot 2011-07-23 14:00:19 He stated that the power supply did not consume its max power all the time. The 0.06c was only an example. Wikipedia is not a valid reference in any valid argument. And it seems most of you need to read the entirer article from what I have observed from your replies. Good article. The math is sound and it does answer some question I have about our surrent office power consumption for the related devices. Thank you. 2011-03-16 20:43:16 I have a device that measures power draw from any device plugged into it. It plugs into the outlet and then your power cord plugs into the device and an LCD display shows power draw. I have an older computer I've set up to do 24/7 BOINC operations, does not have a monitor or any peripherals or sound, just the case plugged in and on-board cards. Has a Smith field Pentium D 2.66 GHZ Dual Core (95w processor), the GPU is not used for processing. The PSU is 450 watts max. The actual power draw at 100% processing is about 245 watts. That just FYI and a guide to anyone who was shocked to see how much their 600 watt power supplies are costing them. Check out your power company's website to see if they have a calculator to help you figure out how much you are being charged; it varies widely all over the world. 2012-12-08 22:16:12 Thanks for the explanation,
Regardless the w = va or 300W power supply will consume 300 W all the time, the final results in your examples are wrong, you should divide the cost by 100 because the kw/h cost is in cents.
So, based on your assumptions, a 500W PSU will cost $0.2709 if the 1KW will cost 0.06c/h
((500 * 100 / 80) /1000)*24*7*4.3 = 451.5 Kw/h for one month
451.5 * 0.06c = 27.09 c = $0.2709 for one month
If we assume your assumptions are correct then one simple formula will be:
Let W = maximum PSU power and the efficiency is 80%
Then cost per month in dollars = W*0.903*Cost in cents/100
500 * 0.903 * 0.06 / 100 = $0.2709 per month
