I just calculated and realize that it costs me about $20.00 a day to support my crunching habit. That's why I went to Maxwells (all 750Ti). Total power bill (Minnesota) is running an average of $325/month for an all electric house. Of course half the year (or more) they're heating the house (almost totally). I'd consider selling some of those energy eaters and invest in some Maxwells. | |

I just calculated and realize that it costs me about $20.00 a day to support my crunching habit. How much does Electricity cost you per KWh? If you updated your GPU's to Maxwell's; GTX750Ti 2GB or any of the 900 series you could do as much GPU work and save a lot on power. Take a GTX580 for example. At GPUGrid it will use around 185W whereas a GTX970 will use 145W and a GTX750Ti will use 60W. The GTX750Ti gets ~86% the credits of a GTX580 but uses 1/3rd the power. It's performance per Watt is ~2.5 times that of a GTX580. The GTX970 gets 70% more credits than a GTX580 but uses ~40W less. It's ~2.28 times as power efficient. The 900series efficiency over the 600 series is a bit less, but still significant. If you replaced your GTX680's with GTX970's you could do both more work and save on electricity costs. A GTX970's performance per Watt 68% more efficient than a GTX680; the 970 can do 25% more work for 33% less GPU power usage, approx. So I suggest you start by upgrading your GTX500series cards and then the 600series. Assuming you have 11 GTX680’s, 6 GTX580’s and 5 GTX560’s (not 448cores), you could replace those 22 GPU’s with 14 GTX 970’s and do the same amount of work. The power usage would be 2.03KW rather than 3.8KW. That would also allow you to do away with 2 systems, if you went for a 2GPU/system setup or 5 systems if you went for a 3GPU/system setup. Alternatively 12 GTX980's would do around the same amount of work and allow you to drop down to 4 systems. They cost a bit more but running costs would drop to 1.98KW for the GPU's and you would have one less system. That's not your only problem though, your other hardware is older. Take your i7 CPU 965 for example. While its only 6years old and is still a reasonably potent CPU it has a TDP of 130W. Its basically a heat monster. For comparison, the i7-4xxx Haswell's have TDP's of between 35 and 88W. That hopefully highlights a large part of your power usage problem, but beneath your CPUs are older motherboards and PSUs (presumably) which may also be somewhat power hungry. For GPUGrid GPU crunching, a potent CPU is not necessary. It only becomes so when you start adding 3 or 4 extreme end cards and then its only worth spending a little extra on a CPU. You could sell your old high end CPU's and buy more basic CPU's with the purpose of GPU crunching, the sale might even fully pay for the purchase. Now though, I would just stop CPU crunching on those systems, or under-volt and under-clock them. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help | |

It's really kind of you to make such a big investment. About 24, assuming none have crashed lately... 9 rigs, all have 2 cards, 2 have 3 cards, and one supports 4. Meow. | |

Now, if you look at that bill, it would be very easy for me to cut it in half. I am on 'time of use' rating... | |

You front me the money to upgrade and I'll pay you back with the energy savings. Only 137.00 each today. x24 = $3,288.00 But Tiger has a 15 card limit. So the kitties will have to set up their own account and buy the rest on their tab out of their kibble fund. Now, suppose that cut my bill in half. Say $400.00 a month saved. It would be a 9 month payback. Cut me a check and I'll order them pronto...LOL. Of course, 24 750tis ain't gonna crunch as much as what I am fronting right now, so the RAC will take a hit. And, oopsie...only 2 rebates per kitty. So 2 x $137.00 and 22 x $157.00..... So that brings the tab up to $3,728.00. Payback is now 10 months. And since it is now 5 degrees below zero f here presently, and 750tis don't generate as much heat, I'll have to fill the 250 gallon fuel oil tank in the basement so I can run the furnace. 250 x 3.28/gallon = #822.50 Tab is now $4,550.50 and payback is now a year. Except that neither electricity or fuel oil are going to be this low a year from now......and we are basing the payback on an PRESUMED savings of $400.00 a month.... Oh, wait a minute.... We are not including ANY costs for upgrading the supporting CPU infrastructure here. You wanna do the math on upgrading 9 mobos and CPUs?? LOL....I can wipe out my 401k fund and retire on the energy savings, right? So.....Here is the math... | |

You can configure Boinc to not run during time frames. I do this as my 3h/day (M-F) peak is £0.28/KWh ($0.42)! Normal rate isn't great £0.15 ($0.23) and low is about £0.11 ($0.17). | |

Total power bill (Minnesota) is running an average of $325/month for an all electric house. Of course half the year (or more) they're heating the house (almost totally). Do you know how many BTU's you're DC systems provide? For example: a cord of white birth is 20million BTU. One split 16-18in x 4in x 6in log is roughly ~13K BTU's. A 40Ib bag of wood pellets provide 345K BTU's. Price for [1] cord of non-seasoned wood is about 225-330$ during New England Winter. Not as harsh as (Northern) Minnesota but close. (I buy and cut my wood in Spring when a cord is 150-175$ and let it season) During the Winter for [3] wood [1] pellet stove(s): I burn about 5/6 cords and 1/4 Ton of pellets. (British Thermal Unit or BTU - is defined as the amount of thermal energy it takes to raise one pound of water one degree F.) | |

Yes, I am aware of the possibilities, my friend. But, the kitties would not be happy with me if I restricted their crunching hours. Might start to nibble on my toes at night....LOL. If cost effectiveness were my goal, I could reduce my costs significantly, for sure. But that is not my end game. The rigs are presently crunching up a storm on Seti. Their servers are on a roll for a change, and AP work is flowing to the rigs nicely. Nobody else on the PLANET does Seti the way I do, and that is something I am very proud of. No worries, GPUGRID is locked and loaded on all rigs as the backup project, and I'll be here from time to time. Just me and my kwhs.... | |

The power usage would be 2.03KW rather than 3.8KW. 2.03KW= 6926 BTU per Hour 3.8KW= 1.297e+4 BTU per Hr. 120W= 409 BTU per Hr. -[1] GTX 970 @ 145W= 494 BTU per Hr. -[1] GTX 780ti @ 250W= 853 BTU per Hr. -[1] GTX 750ti @ 60W= 204 BTU per Hr.(Beyond's 16 GTX750ti provide 3264 BTU's per Hr.) -[1] System with Total Power @ 750W= 2259 BTU per Hr. -[1] System with Total Power @ 1KW= 3412 BTU per Hr. -[1] 1e+5 BTU oil burner= 1.055e+8 W | |

I feel your pain. I dumped American Thieves and Thugs a few years ago because they wouldn't grandfather in my 3GS iPhone after I'd been using it with no data plan for a year. They said a data plan was mandatory on an iPhone on their network. I told them to stick their data plan where the sun don't shine and took my business to T-mobile. They lost a $5k a year customer(phones,internet and U-verse)over a $30 data plan. Morons. | |

Total power bill (Minnesota) is running an average of $325/month for an all electric house. Of course half the year (or more) they're heating the house (almost totally). I don't know the BTU output of my systems. I have a rather large but super energy efficient house though. It's built for energy efficiency (in 1977 no less). The side with the major windowed areas point straight south and have sun porches that are opened on sunny days and closed the rest of the time. Much of the rest of the house also has buffer areas. All interior walls and floors are insulated. The exterior walls are 6". All my heat is supplied either by the computers or wood that I cut from the land around the house. I had 9 big oaks go down in a huge windstorm a couple years ago. Don't know how I'm going to use all that wood since it's only during extended cold spells that I use any at all.. I could get by a lot cheaper if I either used all wood or the electric furnace which uses off peak at a much lower rate. I like crunching DC though. It makes me feel like I'm doing something to help science and mankind. My problem is the summer. Unless I shut down the computers, AC is silly. There's usually a couple days a year I do just that though for the sake of poor Cocoa (my dog). Sadly he died on Dec 27th at the age of 16.3. He's missed. | |

I am kinda stuck with them. I cannot complain about the cell phone contract I have...I was grandfathered in from Cingular when ATT bought them out, and they have tried to get me to switch plans, but I am still on the most basic one they have...and they don't offer it to new customers anymore. The 'net service they have wanked me on a bit at a time, a buck or two at a time, until it is now pretty expensive. But I have only 2 other options. Time/Warner cable....and I don't have a television. Or satellite, which as I have heard is not real cheap and the service gets pretty sketchy at times. I'll stick with the land line........... When, and I say WHEN Time/Warner buys out Comcast, things are gonna get even uglier for many people. | |

@Jozef: take a look over there and run 2 concurrent WUs on your GTX980. You might also want to fix the memory clock, if you haven't already done so. Even more so if you run Einstein or SETI. | |

@msattler: Man, if you are in debt and crunching costs you 20$ per day I would suggest taking a break / selling machines. At least for me it would not be worth ruining my life prospects for crunching. | |

msattler: feel sorry for you - sounds like you have a bit of an addiction problem, all be it a very honorable one. Seriously take these guys advice - put your old machines / cards on ebay whilst they still have some value to gamers. As an incentive think also of the environmental impact of all that energy being wasted. | |

Believe the man. He's right. The purpose of distributed computing is (imho) not that you burn your entire money. If there is not enough left for the house, the family and your next car, there should be a good reason for that. What would you like to achieve? Do you think that you will be immortalized in the Olympus of the eternal Cruncher? Turn off the tap a little more. Then you're still a highly valued member of GPUGrid. And for that, have a bit more reserves. Think it over. ____________ Regards, Josef | |

Older less fuel efficient vehicles are still used all over the world. Whats the difference? The difference is simple: anyone who's driving less than 10k km/year can hold on to his old car just fine. The fuel doesn't cost enough to worry him, but replacing the working equipment with something new and shiny would cost a lot. But for a taxi driver with 100+ km/year the fuel costs amount to a large sum, and a significant portion of the overall cost to run that car. If there's a new vehicle which could cut those costs and quickly pay for the investment through those savings, woudln't this be a smart move? Especially if our "taxi driver" is working on paying pack some debt? It would help him to pay back earlier, or to do whatever else he wants to spend money on. Saying "but the old car still works well" is not helping at all, if things could otherwise be significantly better.

Saying "but the old car still works well" is not helping at all, if things could otherwise be significantly better. But that taxi driver would have to spend money to upgrade the taxi and when he's in debt he can't afford to do that. Everyone is saying well stop driving, save the fuel your spending and use that to upgrade but by stopping driving he is now not able to get the desired result (taxi fares in this example). So as it relates to msattler, everyone is saying saying stop the science being done (this being a project that wants results back very quickly...) and then save up and then buy new stuff that will produce the exact same results. Net result to the science? a loss of 6 months of work done. | |

People have made suggestions. Msattler doesn't want to do them at the moment. I think we should leave it at that. Personally I feel he deserves a big thanks for supporting science projects. How he decides to do it is his business. If others want to do it differently that's their business. There are many bigger issues in the world to worry about without nitpicking this little one. Let's thank everyone for their contribution to science, and move on. | |
