Any update on a solution? I just updated Ubuntu to 12.04 and am running into the same problem...
i have 3 5970's on some random dual core intel CPU with one core disabled, device 0 at agg 9, rest at agg 12 use SDK 2.1? and run them at 150mem with 128 worksize or 300mem @ 256 for maybe 1% more |

I don't understand why you would create a download for a .jpg then hide it with URL shortening instead of uploading it to a photo hosting service then using [ img ] [ /img ] tags. Makes you look shady and untrustworthy. If you peruse some other threads where 5830's sold, you'll see they were sold within hours of posting. When you leave out major SOP's that the trusted sellers use most buyers will not go near the deal. Another reason is the # posts. Finally, your price is a little high and you didn't state if your willing to accept offers or escrow. http://longurl.org/Agree with some of that, however 110 is right around fair market price at the moment. well, they had those refurb ones on newegg for $107 recently. looking at ebay completed auctions, I don't think it'd be too difficult to find a good card for under $100 including shipping their price hasn't really changed a whole lot. if i wanted some 5830's, I'd be looking to buy for $80-$90 (including shipping), as a seller, I'd be trying to get $100-$110 (including shipping). 'course on ebay, you pay the 9% electronics fee (ed: maybe fabrizzop is still overpaying for them, jaja) |

Wow, why are you using such high memory clocks? That is sucking a huge amount of electricity and causing you to have higher temperatures and losing money. Underclock your memory and stop using shitty 2.6 SDK. Use 2.1. I get 294 mhash @ 900/355 using 2.1 SDK.
i re-acquired some sapphire 5830's and I've been running them at 850/195 @ 1.063v, 128 worksize, ~285mhash each. ambient temp is probably around 100oF. the voltage drop dumped them from around 67-68oC to about 63oC |

neteller works just fine, i deposited > $1000 to virwox in the last week.
make sure you pick the right CURRENCY for your wallet because if you want to change it you need to close/re-open your neteller account, they need to call you and its a real pain.
neteller works fine for anyone outside of china, USA |

There's a DDoS in progress. The network provider won't allow any new connections to the site but those that use miners that use keep-alive connections are still able to mine until the connection closes.
You don't happen to be on Rackspace do you? A bunch of our services went down for a few minutes until they nulled the offending IP. yeah, i was checking that too. it's rackspace, |

After some tests, my favorite compromise is: 5870: 870-300@1.06v = 380-390 Mhs 5830: 830-250@1.05v = 266-267 Mhs Less is too low for me at the moment. I run my 5870's at ~215mem and use 128 worksize... maybe 1.5mhash less.. |

Yeah, dump the case and just use a budget floor fan, like some $20 honeywell. Unless you're in ambient temps over 35oC, shouldn't be much of a problem.
I have a temporary set up right now, not the best air flow, but I can still keep all my cards under 70oC with ambient temp generally between 90-100oF during the day (*which is what I need to fix, since it shouldn't be getting to 100oF when it's 85o outside). 3/4 have dedicated floor fan, fourth is water cooled.
(ed: oh, i've always re-done thermal paste on any card I buy off eBay... sometimes from retail)

hmmm, someone offering VCC's somewhere?
my bank refuses to allow a transaction to Crédit Mutuel for an ovh server on their "standard" debit card... I guess I'm supposed to pay $10 fee, then $5 a month, then 2% transaction fee to have ability to do international transactions
things such as walmart gift cards are of no use, since they dont allow international transactions. other VCC, like entropay, present problems primarily due to UIGEA (with some patriot act thrown in). well, for me to fund, anyway.

1) I agree here if you were a dedicated miner who just vents their air outside, but undervolting makes sense who pay electrical and cooling costs (ie. their cards are in a gaming machine). At that point your net revenue may come pretty down close to 0 after cooling costs unless you undervolt.
That is nonsense. Gross revenue is currently ~4x electrical cost. Even with 30% overhead for cooling it is >2x. Undervolting doesn't improve profits. Undervolting is useful in large farms where you simply can't handle the heat. I updated post above to show that. Yeah, not quite sure why some of these ppl seem more concerned with efficiency than profitability. *scratch* But, then, I guess you also have people loading up with 7970's that will decrease in value like nobody's business, so.. Couple months ago, I never undervolted. Now I do so during the day only, because of heat issues (considering different solutions as to where I wouldn't have to do this). Then, I'm speaking from a perspective of anyone that gets electricity for, oh, I don't know, probably 15-20c or so or less. I pay ~8-9c per kwh. |

yeah, I have auto-notify on and it has never notified me about idle workers, either... so, I guess none of the notifications are working except for block solving..
anyway, some new development for the last 8 hrs or so, stats are frozen on the top miners, personal workers section, etc. dunno if that might also have some impact on it showing solved btc/nmc blocks

I ordered with BFL on Feb. 23 and still don't have a single.(Not a complaint) On that same day I ordered 8 7970s for $529 each and they were up and running two days later on the 25th. Each machine is getting 2.5GH/s so I added 5GH/s on the 25th. I believe those machines have been paid something like 150BTC. I am pretty happy with my choice to order GPUs when looking at the possible unknown with the reward cut.
recent prices on ebay for used 7970's: apr 17th - $415 apr 18th - $470 apr 18th - $530 apr 18th - $510 apr 19th - $423 (+ "variable" shipping rate) apr 19th - $435 (+ "variable" shipping rate) apr 19th - $405 apr 19th - $435 apr 20th - $420 apr 20th - $450 apr 21st - $515 (+ "variable shipping rate) so you could sell those eight for maybe $475/ea on eBay (being generous), subtract the 9% eBay electronics fee + the paypal fee.... end up with around $430 (more likely, $20 or $30 less)? you're down $800 since feb 23rd, 150BTC doesn't even cover that |

great resale value i didn't spend $600 on a gtx8800 for its resale value, or $500 on a USRobotics Courier HST, or ... you dont buy the highest end technology for resell value 2 steps down |

Also got one. Very clever phishing email. Looks very natural. I was confused by strange domain tmweb.ruWho here on the forums has access to email addresses?
I think spammers use stolen MtGox DB yeah, using the DB that got passed out june '11, i'm sure. i have the same list anyway, i just got this. points to rgy###.tmweb.ru i didn't think it was very clever though, i mean, all you have to do is see that the link is to some site in russia? |

Can you add a way to automatically turn nmc into btc balance like in eclipsemc?
Yeah, it's on the list of things to do but I don't think you're missing out on a whole lot. 5gh should produce about $1 worth of NMC per month. in the last week i've received 45NMC. about 18hrs total downtime in there, some other periods where i was using a computer, so my guess would be it's ~4gh for that week.. anyway, i'm sure you could calculate out the exact amt you could expect to get over x time with x hashing power, but those 45NMC sold for .40 bitcoins on btc-e (yeah, i was surprised when i checked the price too, it was close to .01 for a while)... that's about $2 in a week |

There seems to be a lot of people wanting 5830s in the Marketplace. Was there some new development that I missed or something?
I noticed that people buy certain cards for different reasons. The HD6000 and HD7000 series are for higher resell value or gaming on, while HD5000 are purely for mining. And within these 5000 series cards, is can be broken down even further. There is the initial cost factor, and mining costs factor. The 5870 and 5970 are good when it comes to hash rates per kwh, but their initial investment cost is high. The 5830 has the lowest initial cost investment, but it consumes a lot of power for the hash rate output. This is favorable for someone with low cost or free electricity. It seems that the 5850 is the middle of the two 5870 and 5830 in terms of initial investment and electricity cost. i'll have to disagree with some of these statements hd6000 and hd7000 may have a higher resell value, but that's only because their value is higher to begin with. absolute $ is what would matter for our circumstance (maximizing profit from mining bitcoins) and the 5830's have dropped $0 in the last year. i haven't tracked 5870 values until about 3mo ago, but they've dropped about $25 (completed auctions on ebay). the 6000's and 7000's have dropped a lot more. not only in absolute value, but as a %. expect that to continue, as more recent technology should *almost* always decline in value faster than older stuff. someone else said they could get 5830's for $60 or something like that, but I don't find that to be the case. you can get them for around $100 shipped easily. you can get them for $80-$90 shipped if you spend a little time at it. the 5850's range from around $115 to $140. the 5870's from around $150 to $200. i reckon 5830's are still the best buy in retaining value, but they also take up a card slot, same as a 5870 does. so, it'll cost you in terms of space, motherboards, etc. i converted my 5830's to 5870's just recently, since 5870's dropped into the $160-$170 range. in a couple months, 5970's will probably be a buy |

I didnt see any gains with 11.1 vs 12.3. Two of my cards run at 1060 with no volts. Hash is 325K. Temps around 65 and fans 55%.
oh, that makes more sense i guess whatever you were using before probably wasnt aggressive enough... maybe using 85% of GPU or something, that would keep the temps down some -k phatk2 VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 WORKSIZE=256 i've noticed when i put the cards above aggression 9, it starts using a good amt of CPU cycles for just minimal gains in hash rate... if I have three 5870's at agg 12, it actually lowers their performance (100% CPU usage).. if I have three 5870's at agg 9, the cpu usage is like 1 or 2%... agg 10 would be about 20%. though i've never tested the actual power draw and whether it's more efficient or not anyway, i've been using some old dual core CPUs I had, w/ one core disabled and the other one underclocked and undervolted.. maybe if you have a better CPU, it wouldnt be so bad. |

The people who buy 7970 have money and want the best.
sure, that may be true. but the best for gaming, I assume? i paid $700 for an 8800GTX, uhm, 6 years ago? i wouldnt make such a purchase just to lose money watching hash values |

Why does the hashrate of your pool vary so much? Does that mean it's getting hopped?
It hasn't varied much recently. I guess it used to get hopped to on occasion because of the bonus? |

Personally, I'm just not interested in new cards. The kings are still 58xx and 5970's and they are less expensive
I was going to sell my 7970, but after a while I fell in love with it and sold the 5870s in my main computer instead. The 7970 can be undervolted so much that they are quiet and cool while getting about 610mh/s. Maybe not the most BTC for the buck, but if electricity/heat/noise is any type of concern, 7970 is the way to go. Especially if your rig doubles as a regular use or gaming machine. 7970 is probably declining in value quicker than any income that 610mh/s minus electricity may bring in... yes, the only reason to get one of these would be for gaming... or if you're doing bitcoins as a hobby and dont mind losing money. |
