If you need to change anything other than your e-mail address, you can use the web-based form here.

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.

Yes! This is how to run Seti as a Scheduled Task in Windows XP:

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.

There have been problems with Dell laptops related to keeping SETI running 24/7. It seems that some of the power management schemes interfere with the SETI software. Here is a method that several members got together on to resolve that issue:

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.

For BBR go to Members then Account. For S@H, click on this link. Click "Change your userinfo", then there should be a box labeled "Email address" and it will have your current e-mail address in it.

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.

Short answer is NO. They interfere with each other. The SETI program is CPU and Memory intensive. The Cooler Programs stop SETI from running and may even cause system conflicts. Don't use them with SETI at all.

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.

Cost of Running SETI 24/7 on a home PC.

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

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.

Feedback received on this FAQ entry:
  • This article is written by someone who has no idea what they're talking about. My power supply is rated at 520 watts, but the computer only ever draws around the 80 watt mark. The rated power is the maximum power it can draw. Also volt-amperes (va) are a measurement of apparent power, whereas watts measure real power. Don't spread misinformation.

  • Thanks! this has convinced me to possibly mine bit coin! now that i know i won't be losing more money then i gain!

    2014-04-21 17:42:24

  • Thank you so much for this post i truly appreciated it... signed a guy who never posts on anything

    2014-03-13 03:28:11

  • Apart from anything, you really need to get your units right. Power consumption is not measured in kw/h (killowatts PER hour) - it's measured in kWh (kilowatt TIMES hours)! If you take any of your monthly examples as read, the total power cunsumption per month for a PC is more than enough to power a small town! Also, your abbreviations are up the Swannee. The Watt is abbreviated W, not w. Similarly, the metric abbrev. for 'thousandfold' is kilo, or k, not K. (Scientifically speaking, a capital K is usually used to denote potassium or degrees Kelvin.) Also, when considering figures in the hundreds, you don't need to quote anything after the decimal point! Haven't you heard of the mathemantical concept of 'significant figures'? This is all pretty basic stuff.

    2013-09-20 08:00:05

  • actually it says $0.06c per Kw/h in the heading about figures so one would assume the calculations not incorrect but instead their is a typo there (surely its just $0.06 per Kw/h) and then the wrong unit has been used elsewhere ($0.06 rather than 0.06c)... If anyone gets their units for that price i wanna know their supplier.....

    2013-07-17 08:43:36

  • 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

  • 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

  • This helps! Thanks for your energy put forth here.

    2011-10-03 14:23:14

  • 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

  • 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

  • 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

  • Is There any extra cost in curred in powering up the computer and powering down

    2009-05-10 18:40:21

  • Watt != VA http://en.wikipedia.org/wiki/Volt-ampere

    2009-01-14 15:56:31

  • 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.

The same way you get the color, you can get different sizes for the certificate also. Just choose the color and the size you want, add to the url and the cgi scripts will render together. Here is the sizes you can choose:

Image size 640x480, add &size=0
Image size 800x600, add &size=1
Image size 1280x960, add &size=2

This thread (thanks Doctor Olds) and the faq about the colors inspired me to write this one.

Once you get your url to the picture, add "&color=1" or "&color=2" or "&color=7" to the end. The cgi scripts will render different colors. Here is a thread with TODarling's 5000 WU certificates in the different colors. This is also the thread that made me write this faq entry.

A SETI@Netherlands member also made a script for it here. It can be used to change many different items of the certificate.

You can download a large number of WU's onto your computer and write them onto a CD. The files can then be copied to the non-connected computer. Note: before the seti program is started it is important to uncheck the read-only attribute for each file as any file written to a CD becomes read only. The results are only small and can be transferred back to the connected computer using a floppy.

Go here and fill in your email address.

If you use Hotmail, it might be in your junk mail folder depending on your junk mail settings.

When you get the password, save the email AND copy it to a text file AND print it. Without this password, you can continue crunching, but no changes to your account can be made. i.e. nickname, email, team, etc.
