When I go above version 2.10.5 with my singles I just get the following. Both the newer versions seem to do it, never had any issues upgrading before.
you need to install the windows USB drivers. read the FPGA-Readme.txt included in the cgminer folder. driver is at http://sourceforge.net/projects/libwdi/files/zadig/when you grab the driver, note that XP uses a different driver than vista/7. |

due to the chip redesign, the chip now sits too high and no longer will allow the HSF to fit in the case.
4-6 week delay to sand down the tops of 6000 5000 chips.
this is also the real reason for burning a wafer; less chips to sand.

nice!
took about 45 minutes on my win7x64/intel 3570k@4.4/8 gig/intel G2 SSD to resync the blockchain.
all in all, a pretty painless upgrade.
thank you.
EDIT: corrected the time.

You probably know that your UPS can supply only 330W of load on its "battery backup" four outputs (the upper four ones). So maybe you connected Avalon on one of the four lower, "surge only protection" outputs.
He did originally, but not now: After 30 minutes or so of mining, the lights in my room flickered, UPS's beeped and complained. Because of some stupidity (plugged into 'surge-only' side of UPS), the miner restarted as well. After some reconfiguration, this problem was solved.
since a an APC BackUPS ES-550 can only supply 330 watts (I have 2 and can can confirm that spec, its also posted online), plugging a 620 watt Avalon into the "surge only" outlet is correct - ie, use the unit only for surge suppression. if its plugged into the "battery backup" outlets the unit will likely just shut down when presented with that kind of load. Aseras is right, get something more substantial. at the kind of coin that thing is cranking out right now its almost certainly worth it. needs 1100 VAC (650 watts) at least, so 1400 VAC (820 watt) unit is reasonable. |

Have you tried measuring the power without the UPS square wave being invovled? I.o.w. plug it straight into the wall (or perhaps with a transient protector only)?
No, though several have requested that. It would be good to eliminate the UPS as a factor, agreed. I believe you mentioned you had it plugged into an APC backUPS 550. if its like my APC backUPS ES-550, it only trickle charges the battery when power is on. normally your avalon will be running on wall power with only surge suppression. also if your avalon draws 600+ watts it wont power your avalon when the powers out. the ES-550 only delivers 330 watts when in battery backup mode. this is if its plugged into the battery backup outlets of course. there are surge suppression only outlets on the ES-550 too. |

Thinking about continuing trial and lowering a=0.8 to 0.75 or 0.7 reduces variance a little and raising cap to 5*D instead of 1.5*D feedback welcome  sounds good to me. just as a fyi. running about 12% behind here, been on it since the 19th. sorta a slow slide downwards, as it was about 2-3 % under for the 1st few days. not complaining, just spouting figures. |

why not just move the data files to a normal drive on the system. that is what is taking the space. that way you keep your the bitcoin client and wallet on your computer just like now. use the "-datadir=<dir>" switch. see here https://en.bitcoin.it/wiki/Running_Bitcoin |

Im 2.4% under. seems ok to me. most shares are under but the over ones do a pretty good job of evening it out so far.. and it IS a gamble of sorts. Ill stick it out some more. makes coming home to see the stats fun again |
|

|

all those number and equations make my head hurt. but.. anything with "pot" in the name is worth running for a week at least, just on general principles. ("DERP" too. Im torn between the names myself)
so, Im in!
EDIT: so all I have to do is select POT for payment method, correct? nothing else to set or choose?

cgminer times how long it takes for the gpu code to "return" after it's been given work. Unfortunately with windows, the timer resolution is so shithouse at 15ms that I have to sample many many iterations of the GPU code and then average them to see how long it took. This means that between giving the GPU code, there are short periods dependent on CPU code, and windows' scheduler does not seem to give this CPU code priority even though folding@home should be idle priority. So it ends up counting delays of the CPU scheduling as though the GPU had spent more time on its work. So it's a combination of the shit windows timer resolution and the shit windows scheduling that makes dynamic not work that well for your test case. No prob. I can live with it, just curious. so, best senario: linux!  'cept the gaming part, which keeps me in windows. ah well.. I LOVE the stratum support! dunno how you do it but cgminer just keeps getting better!
Thanks  youre welcome. donation coming your way, check your PM. make sure it goes onto the stratum side of the scoreboard if youre still keeping count |

question on how cgminer figures intensity.
on dynamic with both 2.9.7.0/1 and 2.10.0 when I fire up folding@home on the cpu (which loads the 4 cores to 100%) cgminer drops intensity down to -8 or so on my 6870. stop folding and intensity goes to 4 or 5 where it should be.
dunno if previous versions of cgminer do this as I just upgraded to an i5 3570k; I didnt fold on the other CPU.
AFAIK folding does not touch the GPU in any way when not displaying folding graphics (which i never do) and it runs @ idle priority.
does cgminer figure CPU load into dynamic intensity?
win7 64 bit
cgminer 2.10.0
11.11 driver
12.4 SDK
HD6870
anyhow, setting "I" manually is fine. and I LOVE the stratum support! dunno how you do it but cgminer just keeps getting better!

Most American home has a nice backyard right? I'm not from America but dont see digging your own yard can be costly. Rent a tool and take a day to dig?
If space is not available you can use water-water exchangers and heat a pond, a pool or household hot water.
need a big back yard. my 3 1/2 ton geothermal system has 2000 feet of pipe buried 5 feet down in the back yard (horizontal loop). you could rent a back hoe to dig the trench if you want; we hired a contractor. smaller yards without the room for that amount of pipe will need a well (1, maybe 2, possibly more) a few hundred feet deep (vertical loop). THAT you need a contractor for. |

Funny you should bring this idea up Farlack,me & my brother have a system we're working on right now to eliminate the coil from your A/C condensor by running sealed copper tubing/pipes into the ground to dissipate the heat.Just getting BTU #'s now with a window unit,but its looking promising for existing units up to 5 tons for residential systems. The main benefit we're pushing is coils are the main thing to fail due to corrosion in seaside homes,in ground copper will elimate that failure point & last almost forever & remove that unsightly outdoor condensor from view  so basically youre talking geothermal. hope youre aware of the length of pipe youll need, my 3 ton geothermal unit (A/C, heat, preheat for DHW) needs 2000 feet of pipe buried 5 feet down, although since its for heating also it takes more pipe as it needs to pump more heat around for heating the house and DHW. heating around here takes more exchange area than straight cooling as the max temp difference is greater. IE 10 F outside to 72 inside in heat mode vs 100 F outside to 72 inside in cooling mode. maybe 1/2 the pipe? 1000 feet call it? |

Already underway This is new in the display of the next version: Block: 029a31ecc6e1269154fd5c6b... Started: [08:12:07] Best share: 7.58M I wondered when that snuck in (compiled from git yesterday). best share so far 104k. been running great under windows vista/7 so far. Thanks! EDIT: say, what does "rejected <hash, stats etc> job '57f7' not found" mean? |
|
|
|
Any guesses how much the total network hash rate will be affected due to power outages etc?
Anyone got generators ready to power up those mining rigs if the power goes out?
got a generator that will run the house, but I wont waste fuel to mine. I went 1 week without power last october storm and my fuel reserve does not last forever, especially when no gas stations within 60 miles can pump it because they have no power either it goes towards heating, well pump, refrigeration and computers in power sipping mode. so count 1.7 GH/s down if the powers out. northeast USA here, they say we will get hammered pretty good where I am. |

Just because you disagree with a policy, it doesn't make it wrong or hypocritical to take advantage of that policy.
I knwo your POINT, but because I'm libertarian that would make the appeal of doing GEOTHERMAL because it has a tax credit LESS effective ok, so dont use the credit. it will just be a longer time for payback. do it anyway. its clean, very even heating/cooling. and (can be) maintained to 1 degree F at all times, you dont have to use timers to setback temps at night or whatever, although you can. its generally most efficient to leave the house @ 70 F [or whatever] day and night. as a bonus, your mining waste heat will be used to preheat your hot water in the summer when cooling your house. |

if you are paying for heat, I would say that it could pay for itself in 3-5 years.
we figure our geothermal system will have payed for itself in 5-7 years. EDIT: thats the combined savings on air conditioning, hot water and heat, all which are geothermal now. |

Maybe I can convince my landlord to get a geothermal system if the utility company will allow some sort of tax break or an incentive program or something.

Another option for economics and efficiency is geothermal.
can u provide link, i forget what that means, using earth heat?
Here's a basics: http://www.youtube.com/watch?v=-ajqiPe_9KoThey have a loop that pumps ground water up to near the surface. This water is normally about 60-70 degrees F (15-20 C) even during the winter. Then there is a "heat pump" that extracts heat from the water and warms the air. This is the exact opposite action as an air conditioner, and because most heat pumps are reversible, it can be used to provide cold air in the summer (it's more efficient to pump heat into 70 degree water vs 90 degree air). Because the heat really comes from the ground water and not the energy source, it produces more heat than you spend. thats not what my geothermal system is. it is a closed loop: 2000 feet of pipe with antifreeze in it, buried 5 feet down in my back yard. ground temp 5 feet down is around 50F year round in my area (northeast USA), and my system dumps heat into it in the summer, and draws heat from it in the winter. as a bonus, when cooling my house some of the heat removed is used to preheat my hot water (desuperheater). so last summer my waste heat from the miners actually was used to heat hot water. slick. |
