You got me in one thing, i don't know how to calculate power usage, i just tried to figure it out on my own, i thought that since it is the amount of kW consumed in an hour then it must be KW/h. is that wrong? please correct me if it is. Non-snarky answer. kW is a measure of power. No different than horsepower for cars. kWh is a measure of work. kW by themselves do nothing. It is an instantaneous measurement. So if you have a video card which draws 300W continually then at any point it time it drawing 300W of power. Power without time doesn't accomplish anything. Freeze time. How much work is your video card doing? In exactly 0 seconds how many hashes can your video card compute? None right. Work requires time. Work = (power) * (time) For electrical work will call it energy: Energy = (power) * (time) Energy = (KW) * (hours) Energy = kWh You definitely have the gift of teaching, thanks for your explanation, i knew i'd heard it somewhere b4... high-school feels like it was a million years ago |

Relax, in the long run you are better off staying away from the bleeding edge. i have some 5830's and i run them at 950 exactly as you are now, they could go up to 1000 but i prefer stability, also 310Mhash/s is very good for a 5830, that's 5850 territory.

Very enlightening thread, kudos! i was thinking of water cooling a while ago until i factored the costs, i said no way. though i'm just running a 4 card rig but i'm planning to expand soon

coming close to 30% inflation, but i don't think it hurts mining at all when you buy hardware in USD/BTC. i buy mostly at amazon since its the only one accepting non-us credit cards.
i think i can keep mining down to $1/BTC before pulling the plug at current difficulty

what could happen if the price hits $1? scary, looking at the all-time charts it really looks like it is collapsing, a mass difficulty decrease could clog the system as the user base leaves

OFF-TOPIC  This is scarily low gasoline is way cheaper than water here, we have more gasoline than water though "Jaua told a news conference that residential customers will be charged an additional fee..."
but you say they it won't affect residential customers. Even if you paid double it's still damn cheap.
he said that, he will not execute, election year, populism, politics, i don't want to talk about it. about it being a good place to mine, i think it is. Maybe i should start offering those services i've seen around here were people rent their mining hardware, i could mine for someone in let's say latvia or germany and it could be profitable for both. haha |

mrb, if you look at my first post you can see that what you just explained to me is exactly what i came up with, the only wrong thing was the nomenclature of the unit.
taking a look at the last power bill there are other charges, but they are fixed or non dependant on the amount of power billed, in a 103.67VEF bill for 986kWh, 4VEF for "fuel adjustment" whatever that means, and 1.06VEF from the billing service itself. No taxes

As someone who doesn't pay attention to detail (it's "kWh" not "KW/h" ), you are almost certainly in error. - Either the extra zero is a typo and you are in fact paying $0.11 per kWh - Or $0.011/kWh is the generation cost and excludes the delivery cost, or vice versa (to know your effective rate, take your total amount billed and divide by our total kWh consumed) Consider also that $0.011/kWh would be at or below the production cost of almost any hydroelectric dam in the world, including the Guri dam in Venezuela, which supplies 73% of the electricity in your country. You got me in one thing, i don't know how to calculate power usage, i just tried to figure it out on my own, i thought that since it is the amount of kW consumed in an hour then it must be KW/h. is that wrong? please correct me if it is. What i DO know for sure is how much i pay for the electricity and how much it is per kWh (right?), in the power bill it says 0.1Bs (Venezuelan VEF) per kWh. The exchange rate is fixed by the govt to 4.30VEF per USD but there is the black market rate at 8.60VEF. i think my mistake was using the black market rate because i think it is the REAL/MARKET rate so 0.1/8.6=0.011, but with the govt rate that will be 0.023 Nice homework there in the guri dam thing but i live in the west part of the country (the remaining 27%?) where we have gasoline thermoelectric generators and since we pay 0.115VEF each litre of gasoline (yes, that's right 0.05USD each gallon) the price of electricity is a bit on the high side, with a litre of gasoline you could generate up to 9.7kWh ( http://wiki.xtronics.com/index.php/Energy_density) i guess the rest are operating costs. I just read that article but you failed to read "Venezuela's biggest energy consumers -- industrial firms, large businesses and shopping malls -- must reduce consumption by 10 percent during a month-long period" that law is not going to be applied to residential consumers let's keep the thread about electricity costs, mining profitability and our own experiences with both in the place we live not in politics and politicians. shall we? |

There is a lot of stuff i don't understand in this thread, in Vlad's defence i might say that he kinda makes it a little bit easier for me to digest and this thread made me stop trusting blindly in pool ops.
what do you guys have to say about rfcpool, it's not in the list. thanks

Assuming you are using guiminer in windows 7 and both computers are connected to the same router/switch go to the guiminer menu click solo utilities, solo password, enter whatever you want there, then set the client path to where your bitcoin client is installed, finally launch it as a server.
Try to find out whats your server IP address, if you're not sure type CMD in the run dialog box in the start menu, once the console opens up type "ipconfig" without quotes, a bunch of stuff shows up but you are only interested in the IPv4 address
Now in the client machine while setting the solo miner your host is the ip address of your server, the port is 8332 and the user and pass are the ones you set in the server's guiminer
i think that's it

Where I live, it's still hot enough outside to require running the A/C, so until it gets colder outside, any additional heat produced by my rig is an additional cost, because the A/C has to run that much more.
This. Man i'm considering in splurging on a bigger A/C to compensate for the added heat in my "computer room", it is currently running for 16h a day so i can survive this heat, that's 21KW/h a day and my humble 4 card rig is using 21.6KW/h a day, thats 42.6KW/h to generate 0.5BTC on average. Thank God in Venezuela we pay $0.011 per KW/h |

If it is possible to get computer parts (including modern GPUs) on the local market, setting up a mining operation could be very profitable. But I guess the lack of electronics is why you want to shop from the US in the first place
The problem with setting a mining operation here is that we do not have the same income that you guys, a high-end gpu costs about a month of salary and assuming you buy a 6950 your still a tiny player unable to offer a decent amount of bitcoins in a reasonable amount of time. There are a lot of sites where one can buy GPUs in Venezuela but we prefer to buy in the US because if you can buy at the official exchange rate the items get cheaper even after shipping and customs providing online services for bitcoin is probably the best way to get them. Are there a problem for Venezuelans to use a paypal account or similar to recieve payment for such services?
No problems with paypal at all, but i'm scratching my head thinking about what kind of services or items to offer. Any hints? please don't say porn |

Another possibility for earning bitcoins would be if a member of your family is good at translating. They could sell translation services online for bitcoins.
HI, i'm a Venezuelan bitcoin miner and i'd really love to sell those translation services your talking about.  I'm trying to start a VEF<->BTC local exchange too. This is actually a good country to live. Yeah that currency exchange control and the 400$ online purchases cap on credit cards is a bitch (or a blessing if you can buy at the official rate) but i've seen numerous people complaining on the fact that they can only get 400 when they can get as much as they want in the black market. Let's face it the black market rate is the "natural market" rate, yeah tricking the system to get cheap foreign currency is ...desirable, but if you can't get them you don't complain you just go buy at the black market. Just my opinion, that is how i do it anyway |

Thanks for the reply Phelix, i didn't read that part. well i think i'll sell it and buy a 5830 then. are they fully supported in v0.9?
i have two in the mail right now, one sapphire and the other is XFX

HI, i'm unable to set the fan speed on a sapphire 5770 vapor-x in a win7 x64 PC although it sets clocks and voltages, it also has a 5850 Xtreme and i can set anything on it without problems.
5770 Dev#3 (i don't know why, where is dev1 and 2?)
5850 Dev#0

i'm in the same boat, i've been browsing websites for days trying to find how to connect many mining rigs working cooperatively while solo mining. i'm already mining with a pool and have many workers setup but i want to try solo mining, i'm just getting hardware to pump over 4ghash as of right now
