keep them cool (low 70s or under i keep mine in the mid 60s) undervolt them. make sure they are on a GOOD psu (for the better voltage regulation). dont run fans over 80-85% it doesnt cool any better and will just kill the bearings faster, especially cheap sleeve bearings. but buy cards with ball bearing fans as they just last and last.
no reason why you can get years out of them. my HD6870 and two HD5830s went a few years 24/7 during btc/ltc mining days. they still work.
my original mining card, a HD4850 single slot blower fan, the fan did die on it after about a year at 90+% fan speed. stuck an after market cooler on it and put it in a gaming rig i gave to a friend. worked for a couple more years gaming till he built a newer game machine.
oldest currently mining card is a sapphire 390 nitro, two years old i think. still running fine.
back in my folding@home days I had two GTX8800 gpus go for a couple years 24/7. they are still working last time i fired them up about 6 months ago.
probably the best investment you can make for gpu longevity (aside from some good fans blowing at the rig) is using a high quality psu. it will provide your cards with clean power. junk psus put trash on the lines that will slowly degrade the gpus, as well as the rest of the system. cant hurt use a good surge suppressor or do as i have done, install a whole house surge suppressor.

I can tell you that with certainty
Personal profits are on their minds exclusively. They don't care for Bitcoin, blockchain, or whatever, all what they are actually looking for is money which they could receive as budget financing if they successfully push this idea into the budget plan for the next few years. Whether it will bring anything of substance doesn't in the least interest these dudes. All the buzz words they say with such a serious tone and pompous view are said entirely with this purpose in mind
i must of missed this rumor.. could you clarify or link to it? you mean russian government wants to mine for itself? ie budget it out (the mining farm) and all profits go to the government? wonder if they would make it illegal for russians to mine for themselves or use others pools. mine to the russian pool or else.. |

Everyone would just fork to a new algorithm that screws whichever government invested tons on controlling Bitcoin.
and thereby render all existing asics useless. all those existing heavily invested private mines.. just so much landfill material.. still.. might be better than having a bitcoin controlled by a government. a new asic arms race will begin. |

There are at least two schools of thought that say roughly the attack you describe is already in progress.
bitcoin cash could be the Chinese govt's attempt and bitcoin segwit the USG's
yeah thats kinda what led me to post this tread. bitcoin is still in its infancy and is fairly vulnerable at this point. and i want bitcoin to succeed. |

Your logic relies on the public losing faith in cryptocurrencies just because a government has over 51% of hashrate.
However, having 51% of hashrate certainly does not mean you can destroy the network. An attacker can only reverse their own transactions or prevent new transactions from being confirmed. All of people's transactions with a reasonable number of confirmations would be perfectly fine.
so they build it enough to be 70% or some other figure that allows them to rebuild the chain from 20 or 30 blocks back. it allows them to blacklist transactions, reverse transactions (with enough hashpower they can rebuild the blockchain back 10 or 20 or whatever blocks, nullifying any transactions they want in that time frame). point would be to have people lose faith in bitcoin. if no transaction can be guaranteed until days/weeks later because the government mine can roll it back that far who will trust it? |

Whilst people still talk about bitcoin in terms of dollars, and how its going to make them rich, its not a threat to fiat. Its when people start valuing things in bitcoin that fiat will be at risk. The dollar remains the "gold standard".
for now that is correct. at some point things may indeed be priced in bitcoin, at the moment its to volatile so once its settles down that could happen. at that point fiat is in trouble. the time for a government worried enough about that to happen is to destroy crypto now (well, soonish). |

I think that it would devalue the currency of the country. People could see it as "This is better than our fiat". From the countries stand point, I think it would do more harm then good.
That's right. The price of the national currency would fall down towards other currencies and became cheaper and cheaper. Add to that nobody can even predict that this insider would be popular among citizens. And only the demand is that instrument that make the price of the new crypto-currency. What if people would prefer to stay with expansive Bitcoin rather to move on cheap national crypto? Too many if. the government that tries to attack bitcoin by gaining enough percentage of the hashrate to make it useless (my premise in the op) is not trying to make its own crypto, it is to destroy crypto in general by proving it unreliable. thus keeping their national currency as the only option. |

I don't really know what to say to your mindset either you don't own Bitcoins or simply say you know nothing op. If government were to do that, it would be regulated and one would have to pay taxes, what's the point of using such thing. Then again government would have full record of this and it would be suicidal to use it, what if they suspected you of cheat and they could take away all your coins.
heh. been in bitcoin since 2011. its already more or less regulated here in the usa; I claim it on my taxes. quite happy with crypto, its paid for many vacations and toys over the years. i want to to prosper. and the object for such a government doing such a thing is to destroy bitcoin (and thus by trickle down theory other crypto), not make its own blockchain based currency. bitcoin and crypto as it exists now can be a threat to (some) governments based fiat. |

EDIT: goal is to for a 51% attack on bitcoin to cause people to lose faith in crypto, thus destroying it.
The same reason why they cannot stop bitcoin because when they do that, then their currency will be limited to their own country which will not be valuable for international trade in which we all know play a dominant role in the development of any country. Aside that going that route would then mean that government is approving crypto currency which might therefore means overhauling the whole financial system. Also, the next issue of concern would be the privacy in which majority of the already exposed to bitcoin will not trade for anything else.the goal of such a plan is to destroy faith in crypto, not approve it. thus preserving the existing fiat currency. destroy crypto from the inside so to speak. |

Attacking the system how? do you know if a government attacks Bitcoin then we have the possibility to fork the blockchain and have a coin without the government control? then what, they will have to attack the new chain but how long could they keep burning cash just to hit a wall? there is no way for any gov to destroy a decentralized network, that's the whole point, unless they start killing every body running a node and mining, beauty of crypto currency is the same immutability. destroy one chain and another chain will pop up.
fork it how? if you change the algo so the government asics dont work the existing ones will stop working also. |

All they have to do is cut off the banking to all exchanges and anyone they can link to P2P options.
That'll take out 95% of the interest. It'll survive of course but it won't be any type of large scale challenge.
Why mess around building warehouses full of hardware when it can be done with a few threatening phone calls?
that could work, definitely would hurt it. but wouldnt they need to do that for every country? |

1st, modify it into a 8gh/s jally if you havent already.
then use as paperweight.
other than that point it at a solo pool.

Bitcoin's current market cap is around $68 billion usd.
Countries like north korea and afghanistan are credited with having as much as $6 trillion dollars in natural resources: metals, rare minerals, etc.
$68 billion is nothing to a big government. Their foreign policy may revolve more around controlling swaths of land which contain trillions of dollars worth of resources rather than focusing on things like bitcoin which are worth exponentially less overall.
true. not all governments care about crypto. some do as they cant control it. that factor makes some governments uneasy. countries with unstable currencies dont like people moving funds to crypto. its very easy, probably much easier than moving it to precious metals for example. |

nice theory you have but in my opinion all these things will "damage" bitcoin, i do not believe any of it can "kill" bitcoin or any other crypto for that matter. that is why i said there are easier and cheaper ways of just "damaging" it with same effect.
it wont kill it but damaging it to the point where hardly anyone would use it is about the same thing. all that needs to happen is people lose faith in it. if you cant trust a transaction what good is it. what cheaper ways are there to damage it? making it illegal may hinder it but its getting harder to do that as many countries have legalized it, even the usa recognizes it and they would have a hard time reversing that. isps could block bitcoin ports but that can be changed easily enough. block pool ips maybe. but those could be changed too. offhand i cant think of any way to damage it really. have any examples? |

Yeah that is the mobo.
I paid 203 for:
a full case
a E3-1240v2 quad cpu
a 500gb hdd
a good win10 pro
8 gb ram
a working gpu
a working dvd rom
power cord
90 day warranty
seems like a nice buy, especially when factoring in the win10 pro license. are you using the built in psu for powering the mobo and drive? if so whats the efficiency of the built in psu? what is the power draw of the board only? i would think that cpu is power hungry, i like using low power "t" cpus in my miner. but might take a long time to recoup power costs considering how good a buy that is. |

EDIT: goal is to for a 51% attack on bitcoin to cause people to lose faith in crypto, thus destroying it.
first of all the hashrate of bitcoin is too big which makes it a very costly attack for anyone. and also 51% is not enough, there needs to be a lot more to successfully pull it off. secondly it won't destroy bitcoin. it will cause a temporarily issue in one block that said fork happens and as soon as it happens, everyone will be on alert and will require much more confirmation making the attack even harder. and also eventually it will become hard and expensive enough for them to keep the attack up. on top of it the government won't gain anything by this in the end. they've just wasted tax payers money on something useless which will disrupt the network temporarily (the effects will be less than the fear of Aug 1st). there are easier ways to attack bitcoin like simply making it illegal  p.s. if government wants to disrupt anything they will do it with Monero and other anon coins not bitcoin which they can track! yes 51% may not be enough but they could easily go for 60% or whatever they need to give enough control to make it unreliable. as for making it illegal that would be country specific. people would find ways around that. i use bitcoin as an example as that the one with the most legitimacy and cause people to lose faith in that and they may not trust other crypto also. good point about monero but that doesnt have enough users compared to bitcoin at the moment. most people have at least heard of bitcoin, hardly anyone outside of crypto has heard of monero. attack the most visible crypto (bitcoin), prove it unreliable and it will trickle down (i would think so anyway). |

Not only because governments would have to forsake their own currency--that's debatable--but committing a 51% attack they'd be ruining bitcoin and would therefore defeat the purpose of doing it. Of course if that was their original intent...
The fbi seized all those silk road coins. Why would the US government need to mine anything? That's a cynical view but it's nevertheless true.
yup destroying bitcoin would be the goal. usa just prints more money if it needs it no need to mine it.. |

Its very difficult to ger 51% of all hashrate, andpeople wont like to hear the govern are wastiong millions of dolar to buy/make asics only to destroy a currency wich the people loves.
some governments wouldnt care. since when has things that people like but governments dont like stopped the government from doing things. might be possible in some countries to hide the mine and associated infrastructure.. very difficult depending on the country though. one (or more) government finances it, set it up in a third world country maybe. |

I think that it would devalue the currency of the country. People could see it as "This is better than our fiat". From the countries stand point, I think it would do more harm then good.
goal is not to promote bitcoin, goal is to destroy it by 51% attacking it. if they control the blockchain, no one will trust bitcoin anymore. |

At this point, it's mathematically impossible to get to 51% by mining alone. Per CoinMarketCap, 16.5 million of the 21 million have been mined already.
not 51% of the coins, the goal would be to control over 51% of the hashrate. then that government could block transactions, double spend from taht point on, stuff like that. search for "51% attack bitcoin" to see what i mean. the goal would be to destroy faith in bitcoin and blockchain based cryto currencies.. for some governments bitcoin is a threat to their fiat domination. |
