Judging from the posts in this thread, none of you except the OP actually have owned a 5970. Luckily for the OP, I have.
The fan can only be adjusted from the second GPU. The fan setting in the first GPU is a dummy setting (always shows 30%, can't change it. If you try to, it will fail). The second GPU is the one that controls the fan. Bear in mind that fan control on the 5970 is a little wonky. Speeding up is usually instantaneous, but slowing down is done slowly, so if you try to decrease fan speed and it doesn't seem to be working, give it a minute.
my 5970s have always had first core control the fan, though they get reversed in cgminer it doesn't matter much anyway, they are always at 100% ^^ person up above, screenshot is essentially irrelevant since it appears you've either wasted money on water cooling or aren't using the stock fan/fan power connector, as both of them read - oh, i guess i'll also add that the last two 5970's i had, I ran at 835-825-795-845 @ 1.05v, you're running those at 1.1v at much lower speeds |

The cost of air conditioning during the summer must be considered if you run anything more than one or two GPUs and it is hot outside. Right now for me it is just no good to run the GPUs anymore in Texas, even with a good low rate, because my apartment has an older less efficient air conditioner which I can not influence other than to move to another apartment.
It's possible that maybe nothing else changed, during winter running the GPUs would break even.
I am strongly considering purchasing some "USB Block Erupters" from BTC Guild. If I sell GPUs, which have earned their keep over time, it's like free money to spend on the USB devices - which would seem to use only tiny fractions of electricity. Then I can sell off other rig parts, since I only need one extremely modest computer to direct the USB and Bitcoin client. Seems like a good idea to just let these run virtually forever - until they fail otherwise or become unprofitable due to unpredicted advancements.
well, i'm in Tyler, about 100 miles east-southeast of dallas... don't need an AC... all my stuff has always been vented from outside air and i'm turning it all off tomorrow if price stays below $80  |

i just turned my stuff back to p2pool for a final hurrah i suppose you could say, before i shut everything down
but doesn't anyone find it concerning that someone has 33% of the hashrate? i also was unable to locate the IP address of this person, so they're probably behind a firewall, without many outgoing connections, judging from the other nodes I checked (IP address reported as relaying their share is quite a spread)
just found it curious since i've gotten 2 orphans out of 6 already, both because of the double share from 1Nasty
although i guess it could be partally attributed to using a US server
Why would it be disconcerting? p2pool is really small. there are filthy rich miners who have more than the entire hash rate of p2pool. M because it decreases efficiency of other people using p2pool when someone is using inefficient connection and is able to put out 33% of hashrate? does it need further explaining? ok, so i just decided to check the headers for the hell of it P2Pool > Share 9c6eb9d6 Parent: ded30170 Time first seen: Thu Jul 04 2013 07:36:10 GMT-0500 (Central Daylight Time) (1372941370.955215) Payout address: 1MAv44YHbeh9mt3tHUdxDqG7J8acjA9byh trumped by: P2Pool > Share ff119beb Parent: ded30170 Time first seen: Thu Jul 04 2013 07:36:11 GMT-0500 (Central Daylight Time) (1372941371.258362) Payout address: 1NastyFRkeUTmMdbMmzggDVTQA6r3ibUoX P2Pool > Share e82be749 Parent: ff119beb Time first seen: Thu Jul 04 2013 07:36:13 GMT-0500 (Central Daylight Time) (1372941373.962954) Payout address: 1NastyFRkeUTmMdbMmzggDVTQA6r3ibUoX so 1 out of 4 headers that happened to be shown |

I am mining at 220 MH/s, are there any reasons why I shouldn’t raise my difficulty? If I were to put it at 512 would this have any negative impact on my side? It's just less traffic right? I already know this doesn’t change my chances of finding a share of the required difficulty. I'm just wondering what happens on my end.
At that hashrate, you probably don't want to increase difficulty. It will not significantly change network load but will increase income variance. This gets to the crux of my question. How or why would it increase income variance at a pool like p2pool where we are looking for high difficulty shares. I'm not disagreeing with you, I'm asking why? Do we need to submit these lower diff shares for some reason? At 220MH/s estimated time to share is 8 hours. For instance, that means that there's 5% probability of not finding any shares for 24 hours. For two week period, your estimated number of shares is 42, and there's 5% probability to find 31 or less shares, which means only 75% of estimated income. Of course, this also works in positive direction, and your income may be higher than estimated as well. Now if you increase your share difficulty, this variation will be even higher. If you are not a gambler, you want stable income. When mining in p2pool, your income variance depends on both pool's blockrate variance and your own sharerate variance. For details see my post here https://bitcointalk.org/index.php?topic=18313.msg2060914#msg2060914I guess the only thing I would disagree with you about would be that when I change local diff my time to share goes up. The p2pool estimated time to share only goes up because I'm submitting less shares no? It's not a real measurement of hash speed. Doesn’t the work I’m doing locally stay the same I just submit less garbage. the answer to your question is no, it wouldn't change anything, unless this amount was higher than the share difficulty i.e. MrT/500+500, wouldnt matter. MrT+2000 would, if the share difficulty was under 2000 the hash rate reported on your stats will be bizarre (that's what it uses those small ones for), but in the grand scheme of things you'd still get just as many shares |

i've had like half a dozen fans fail, but if you're running reference cards they only cost about $10 to replace anyway
i always run (ran) the 5970 fans at maximum
|

i've had assorted cards running since around mar '11
never had a 5830 or 5870 die (~30?), two of my 5970's (out of ~10) had one core go bad

I still can't understand how you are failing to grasp this.
Say I have 1x 7950. It can achieve 590mH/s mining Bitcoin or 650kH/s mining Litecoin.
This currently equates to 0.139 Bitcoins per day (currently $1.24 in USD), or 0.777 Litecoins per day (currently $2.31 in USD).
Therefore Litecoin is 187% more profitable than Bitcoin on a 7950. Where you are getting this information that mining Litecoin earns less than Bitcoin I do not know.
THANK YOU for posting NUMBERS and not speculation. THANK YOU. This makes intelligent conversation based on metrics that are real. First a 590Mh miner does not make 0.139 BTC it makes 0.0139 BTC. However my calculator puts that at $1.19USD so your main point is still valid, the USD money in the end is about what you said (with the dropping BTC value from the time you posted until the time I posted). I get 650Khash = .77 LTC (2.05019 USD) (also dropped from your post time to my post time) So yes that would appear more profitable! You are right. But how do you get 650K/hash when it was 590 M/hash? Is there a mining rate converter somewhere? Sorry I appear to have missed out a .0 on the Bitcoin amount. 0.0139 is the correct amount. In my case based on personal experience, using a 7950 I have never been able to get above 600MH/s stable mining Bitcoin. 590MH/s stable can be achieved with GPU engine overclocking. The same card (Gigabyte WF3) flashed with F43 BIOS does 650kH/s mining scrypt on stock clocks. i have a powercolor 7950 that runs stable at 1250-175, that's ~645 mhash. hm, probably would get 650-655 at 8 *intensity (sigh) but i usually run it at 1200-175, 617mhash or so if mtgox price drops below $80 is when I will turn all my stuff off (or after next difficulty increase). my time is worth more to me than what i would earn at that point oh, re: stuff remaining stable for weeks. maybe if you have all your stuff in an enclosed air conditioned space? i have to close the window every time there is a thunderstorm (fairly frequent). regular rain showers would be OK, but thunderstorm with swirling winds and what not, rain flies into that room from fan. so, window has to be closed and then room gets too hot, so miners have to be stopped and turned back on later. also, there are power brownouts every week or so. |

I don't know the warranty policies of the other brands, but for MSI at least the warranty is based on manufacture date... so you can sell it used & it can still have a year, 18 months or whatever on the warranty.
Only other thing I can think of is that I hate the Gigabyte 5870 card with two fans
oh, there are those sapphire 7970 vapor-x cards on newegg for like $325 right now. regular for $300

litecoin mining is still profitable.
i have no clue about litecoins, but bitcoin mining is still profitable, too. it's something like .21 or .22kWh is break even point. but the thing of it is, you aren't figuring in the value of your time and equipment loss/depreciation. i don't consider it profitable at .06kWh, but I've been in the process of selling my stuff for a while (especially the 5xxx cards). in the meantime, i keep it running... in part because I dread cleaning out the room where I've been running most of my stuff for the last 18 months |

I just got a brand new 7790 for 122 Euro, giving me 260 MHash/s and only pulling 50 Watt.
if you do rebates and live in the USA and not in one of the states where you have to pay a sales tax to newegg (like texas, hoho), they have the MSI 7790 at $100 again http://www.newegg.com/Product/Product.aspx?Item=N82E16814127726the games arent worth as much now, but bioshock + tombraider, i couldnt imagine getting less than $15 after fees on ebay for still. so like $85 (€65) i get 310mhash on my 7790's, but that's with settings that wouldnt be the most efficient for most people, i just get really cheap electricity i bought a 7770 when i saw one for $80 w/ refund + games (ended up being like $65 or so), it does like 210mhash those were bought with mining for a month or two then reselling in mind. if i bought one now, i'd probably just do the rebates + sell the games + then sell it new in box on ebay |

i dunno, it'd depend where you ordered it from i guess, since you dont specify
order one from a reputable (re)seller on ebay and it'd just be a few days probably

i think bitcoin price will keep falling as long as ppl keep buying overpriced asics and then think they can "pay it off" by mining with it at 50 trillion difficulties
I'm thinking exactly the same thing. In fact the recent fall from ~130 to ~100USD pretty much corresponds to the onset of ASICs. Mining/speculation is a HUGE part of the market. I think that trend will continue, too well, I was wrong about difficulty, anyway... it's going to go up like 11%, not 20%.. so I guess I'll leave the GPUs I have left going as I sell them off, well.. I'm also basing it off a price of $95, which I think will drop more... too many people still trying to "pay off" those overpriced ASICs from asicminer... but @ $95, it's about $40/mo for ghash, after elec (if it had gone up like 25% or so, i think i'd just shut them off, possibility of equipment failure + my time spent == greater than what I get from it, etc) |

get some 7790s, it has currently the best price/hashrate ratio and best power consumption/hashrate ratio: https://suryarpraveen.wordpress.com/2013/04/23/amd-destroys-nvidia-at-bitcoin-mining-can-the-gap-ever-be-bridged/If you have more money then go for 7950s. The CPU I would use is an AMD Trinity or Richland APU. They are cheap and they can be used as an extra GPU. The A10-5800K gives about 114 MHash/s for Bitcoin mining, and about 70 kHash/s for Litecoin Mining with a TDP of 120 Watt. The new A10-6700 should be at same level or a bit above, but consumes less power. The A10-6800K should be even better but power consumption should be close to the A10-5800K. ^^ that is correct 7790's are the best thing to buy right now, if you aren't taking pci-e slots into consideration 7950's will drop in price a lot more than 7790's. 7790's can do 300mhash on about 70 watts. you can get some of the brands for less than $100 on newegg if you do the rebates and sell the games. i've purchased a few (7790, 7850), mined for a month, then resold the card for profit even after ebay fee. but that was about ... 6 weeks ago, when it was worth the effort 7790s vs 7750s? hmm, I never tried a 7750. I did buy one MSI 7770, it was $78 AR + Far Cry 3 & Far Cry 3: Blood Dragon. I gave away the Blood Dragons for free, but the Far Cry 3 game made me $15 on eBay, $13.50'ish or so after fees... so it ended up being about $65 for the 7770. it's been going at 220mhash for about 50 days, i'll probably offload it the difficulty jump after next.. But $65 isn't much less than a 7790, since the 7790 comes with tomb raider + bioshock, (which used to be about $25, maybe $20 now?).... about $20 more or so for the 7790 vs 7770 ed: http://www.newegg.com/Product/Product.aspx?Item=N82E16814131477 ... powercolor 7770 for $80 if you dont mind messing with a $30 rebate |

I'm a low end miner. I'm also a windows developer ... linux makes me cringe.
I wish I had the BTC to throw at getting a Blade. But since I don't, I'll speculate.
I'm guessing the blade has its own built in miner, as opposed to using outside software? I have a number of the erupter USB miners, and they all work great with cgminer in p2pool. You say it needs a proxy, so that tells me it uses getwork instead of stratum? Connecting straight to p2pool with getwork is a no go?
M
Yes. Connecting blade directly to p2pool results with thousands of warnings about wrong target: Worker lenny_beblade submitted share with hash > target Blade has it's own getwork unit. It can work on any central getwork pool and it's fine (apart from low efficiency). It can work with stratum mining proxy and it gets 99.5% efficiency (perfect combination) with central pool - on p2pool stratum proxy just won't work, with forrestv custom patch (a few pages earlier he published it) stratum proxy works fine (with cgminer or something), but still not with blade and p2pool on it.

I have a couple (or one, maybe, with diff addresses) of people with Avalons (I think, 60ghash or so) that have my pool as a secondary or tertiary.... and I see a lot of ^^ that in the log file... but about 50% of their stuff comes through fine. You're getting 100% DOA? ed: actually on second thought, it never says target: fffffffffffffffffffffffffffffffff i don't believe. so it's not even acquiring the work, or ? yeah, it's never identifying your worker |
