Indeed. Its almost as if Gyrsur only wants to know what IP to DDoS?
Or, it's almost as if he is accusing Tycho of mining blocks with our hash power for his own profit. But maybe I'm misreading what he is saying. Sam I was curious about the node I posted earlier because it was running the deepbit website (or some excellent facsimile) and chrome popped up some BS about how I could be going to somewhere that wasn't what I thought it was. as for 83.169.22.26?? shrug |

Does anyone have any data on: 1. The average latency of a connection. 2. The average data transfer rate of a connection. 3. Average number of lost connections per time of connection. 4. Percentage of transactions in new blocks, up-to-date nodes already have. I'm trying to calculate the benefit of the proposal here: https://en.bitcoin.it/wiki/User:MatthewLM/ImprovedBlockRelayingProposalThe proposal increases latency but increases parallelism and removes redundancy. It may increase or decrease bandwidth usage depending upon the amount of redundancy saved vs the additional overhead. Jeff Garzik seems to think that latency is the biggest problem when downloading blocks and additional latency would make things slower. Is there data to support this? Of-course, I'm considering the future: when block sizes could grow into several MBs and beyond. Shouldn't we prepare changes for this now? Maybe 6 months ago... latency is much less of an issue now with the increase in size of the blocks. A dial-up connection has about 120-150ms base latency (transfer speed, ~5kB/s), a satellite connection approaching 1000ms (can reach 100kB/s+ easily).... If you're transferring anything over, uh, 30kB, it seems to me like it would be preferable to connect to the person using the satellite connection. It's not something that would require a lot of ACKs (like, say, online gaming) Umm, I have some log files that may be useful, I've been running with around 900 connections |

Updating this thread again. Just tried to reformat the drive and did a fresh WinXP-install and the first thing I did was to install Catalyst 12.1(with the included SDK) and nothing else.
Then I started GUIminer and set it up just like before, and guess what? THE F***ING PROBLEM STILL REMAINS -_-.
What the hell could be the problem? Could one of the cores on the card be broken? Or could the problem lie with the pool rather than my computer? Or could it be some strange setting that I'm unaware of?
Might try installing Ubuntu instead and see if I can get it to work there.. If not I think I'm gonna sell the 5970 and get a good singlecore-card instead..
use phoenix and get windows7 |

Why wouldn't they be able to?
It was my answer to his suggestion. Shares would be rare, and getworks are often higher than accepts for backup pools. i'm confused... why would this be so? |

yeah, it is definitely not 1.5 to 1.7ghash. i have a cluster of 3 5830's that i run at 1.063v, 915/195 during the day for ~870mhash and if i'm feeling enterprising i'll boost them up to 1.163v, 1000/195 at night for around ~1000mhash.
they are still very profitable vs cost of electricity, if your electricity is 8 cents.
though, buying a new system & cards vs already having the system & cards are entirely diff matters.
since it seems you already have the mobo & PSU to be able to run 3, if your electricity is under 10c, i'd say it's worth it to get a 3rd. should be able to get one for around $75-$80.
i wouldn't be in the market for a 7970 at this moment, seeing as how 7990's launched a few days ago. why not wait a couple of weeks?

I've started mining with a small rig. I've picked up a couple of used 7970's. I'm running ubuntu 12.04 with cgminer.
I actually, don't know that much about the cards I bought. One is a single fan 7970 that takes up 2 slots. The other is a 2 fan unit that takes up 3 slots. Call 'em card 0 and card 1.
I start cgminer with the auto fan option.
Card 0: 1185 Mhz CPU, 1035Mhz Mem Clock, 85% fan, 74C
Card 1: 1185 Mhz CPU, 1035Mhz Mem Clock, 35% fan, 72C
Both are generating 706Mh/s.
Sweet!, But I think it's a bit hot. So I think - kick up the fan on Card 1 (85%) and maybe that'll dissipate some of the heat from Card 0.
Now: Card 0 is 68C; Card 1 is 59C
But Card 0 is doing 650Mh/s, Card 1 is doing 706 Mh/s.
Could/Does the temperature affect the hash rate?
i don't know about 7970's specifically, but ppl tend to give figures way too low for "safe" temps (esp on overclocking sites) if the 7970 is anything like a 5830, 5850, 5870, 80o (or probably even 85o) or lower for the GPU is fine.. as long as all GPU sensors are below 85-90o and all VRMs are below 100 (well, these I think are fine up to 110-120, but...) until about two months ago, i kept all my cards below 70o. but not really possible now in this heat. i'm in texas and the comps are in a sealed off room, it's well-ventilated but temps still get to be about 5-10o above outside temp. so if it's 100o outside, it's 110o in there. it's cooled down a bit lately, but back when the outside temps were 105o, i'd have a few cards that would get close to 80oC during the day, lately they've been topping out around 75o... a lot of times if you have old thermal paste on there or someone gunked it on there, what you see as your main GPU temp could be rather misleading. there have been several cards I've gotten off of eBay that'll read 70oC but have gpu 3 sensor at 90 or 95oC. that's not good, it usually means 'take this pos apart and re-apply some thermal paste', on rare occasions it means 'take off this pos fan and shroud and ziptie a super-loud badass 120mm fan on this mofo'. i have one of the latter. i put it at the bottom of my stack since it takes up 3 slots w/ this massive 120mm fan, but it keeps the middle card a lot cooler too. |

whenever i need to redownload the blockchain or need to catch up a lot, I'll just use the connect option to connect to one (fast) node... seems a lot quicker like that

When I stay synched to the network how much upload bandwidth does it consume on average?
if you don't put any limits on it...... random. depends on how many people connect to you that are missing blocks, and what your max upstream is  that is my bandwidth usage, 98% exclusive to bitcoind. rest of the data would be me just checking out log files and such. that's with 800-900 connections if you don't allow incoming connections, you'll only have 8 (I think) |

why are you so certain this thread has anything to do with it?
this is same BS I read last time ppl were invited en masse
wouldnt the more likely conclusion be that the supply is outpacing the demand?
Because: A) I've watched it occur in real time over three independent threads. B) Pirate has stated as such C) People are greedy. a) yeah, each time after people were invited. see page 2 of this thread. b) well.... i guess i don't even have to say anything to that c) isnt relevant.. if people were greedy, then supply outpacing demand would lead to the conclusion that I wrote above |

There are lots on ebay. This one is 10.49 USD with free shipping to domestic USA. http://cgi.ebay.com/280800583937But TBH, I haven't replaced a single fan since I figured out how to repair them without disassembling the heatsink or fan. Just need a small off center hole on the face of the fan to insert some lubrication oil, and fan works like new. It's a gamble if you want to resell something like that though. Keep in mind that most of those fans on eBay are not exact replacements. You'll have to cut off that tab that holds the wire, since the original fan has a narrower tab. I've put two in fine w/o modifying them in any way. Yeah, you do have to maneuver the wires into the proper place |

I'm still working on the issue. The !#@$@%#$%!%#@$ block chain is just fucking ridiculous. Seriously. I had forgotten what a joke it is.
There is no possible way bitcoin will ever take off in the mainstream simply due to the blockchain being completely, utterly and unequivocally unmanageable. I even downloaded a pre-built block chain and it still takes hours upon hours on an 8 core system to catch the block chain up to the current state. Seriously. It's ridiculous.
In any case, things are almost done. Because the other servers are so flaky, I am just going to do a hot swap of the IP addresses and miners should start repointing. I will take US2 and US3 offline and repoint their hostnames to the new IPs. If you stop getting work from US2 or US3, flush your DNS cache and try again. Alternately, your systems should fail over gracefully after the DNS entry expires and your system picks up the new ones.
So I'm just curious, how does the blockchain get distributed? Is it shared like in torrent? sort of, yeah. the client defaults to 8 outbound connections, if you don't allow inbound connections there's a possibility that you might connect to 8 ppl that throttle their upstream or dont have much to begin with. but in most cases you'll be spending 98% of the time processing the blocks that you've already downloaded |

can u repost kernel for phoenix 1, your links are broken
thanks
i have some of the older ones (that are/were on mediafire), none of those others though http://www.nogleg.com/archive/ |

You can estimate the 10% commission all you want, but the system is dynamic. Every time a (larger) miner lowers their cost per share, the average decreases. As we all scramble to maximize our return we end up shooting ourselves in the foot.
When someone publicly posts a price and how much lease work they're getting it causes a bunch of other people to adjust to try and get more leased work. However, at some point the increase in lease work does not outweigh the decrease in PPS because too many people are doing it as a direct response to the public posting. Case in point: Before this thread I was leasing near 100% at a decently higher price than was posted by the OP. After this thread, that dropped to about 25% because those who were only getting 50% leased at a PPS above what I was at all dropped theirs to chase 100%.
why are you so certain this thread has anything to do with it? this is same BS I read last time ppl were invited en masse wouldnt the more likely conclusion be that the supply is outpacing the demand? |

Intensity is the amount of work in one go the GPU has to do before it can return its results. It needs to be large enough to keep the device fully utilised yet not so overloaded that the device becomes unresponsive. The faster the GPU, the higher the sweet spot is. Ram is of no use to mining whatsoever. They could even mine fine with only a few MB of ram.
pretty sure most people will run into a roadblock with their CPU before their GPU. you could keep increasing it and get some infinitesimally higher results except your cpu will hit 100% usage i have 4 5870's on a single core sempron that i run at agg 7 in phoenix, because at agg 8 the cpu is 100% |

I've never sold anything on Amazon... though I have noticed that the prices on there are ridiculously high for used computer stuff. didn't realize any of it actually sold.
what are the fees there? is it more than the 9% ebay takes?
|

I would like more than 300 per 5970.
well, you can get them for cheaper than that on ebay, someone has flooded it in the last week or so. looks like close to half went for under $300 in the last week. bitcoins dropping in value 33% in the last few days wouldn't help either. 'course that guy that sold all of his for $290-$325 also had to pay 9% to eBay and I believe 3% to paypal. the $280 offer was good, up until the expedited parcel part |

It's a gamble if you want to resell something like that though. i have ordered 4 from that guy in two diff orders. both times within three business days, ordered two on sat morning and got em on tues. so i bought two more on tues and got those on friday sometimes you can fix them like that.. i had one like that, though it died again in like 2 mo |

there are no tiers on my current plan. for the last 6mo it's been ~8c/kwh,
this is near Tyler, Tx
Natural gas prices, which dictate the market price of wholesale electricity, remain at record lows. (well, for this area anyway)
but, there is this other plan, where the first 1500 kwh is 10.9c, next 1000kwh is 9.3c, and all kwh after that is 6.9c
then this "Large Power" plan where the minimum bill is $475, with rate of 5.14c
all the poor wind farms that cant even get their electricity on the grid
Wow which provider provided this Large power plan in TX? I wanna check the availability in Houston! it's a coop... wouldn't be available in any area where there is competition, I guess? http://www.tvec.net/member-info/rates.htmlnote that it says .1048xxx but the last 6 months or so have actually been adjusted -2.5c because of "cheap natural gas" after looking at 'large power' more, i think you'd have to use some extreme amts of energy to make up for those flat charges. i was also just assuming the 2 to 2.5c reduction applied to all the other plans too, but maybe not. there's the $20 meter reading fee, but i'd have to pay that anyway (i.e. not some extra charge from running tons of computers) |
