temp is not an issue i think, i put it outside of my open setup so it sucks completely fresh air from 30cm fan. Looks like lack of power. If i were to buy a replacement should i go for single rail or it doesn't matter?
single rail is just easier to manage and probably easier to sell on ebay too |

I've been mining on P2Pool for a week and I'm very impressed. I had a lot of problems with Phoenix originally but since switching to CGMiner all the stats are now good and I'm earning more than I ever did with 50BTC.
The only remaining issue is that the bitcoind getblocktemplate latency constantly increases over time in quite large jumps. It starts around 0.5s and creeps up slowly to around 2s then jumps to 10s and stays there.
Restarting everything: Bitcoin-qt, p2pool and CGMiner fixes it again but within 24 hours it'll be back up again.
Anybody have any ideas what could be going on ?
Thanks
not sure about large jumps, but if your bitcoind is accepting transactions into memory that no pool will ever include then it'll gradually get slower try bitcoind getmininginfo and see if it's much higher when it starts getting slow (or bitcoin-qt or whatever) |

I think it is better to buy 2x7850 then, and adding two more later...
agreed 7850 is best buy if gaming isnt a concern, can be had for about $100 after selling games + rebate. resale value wont drop much below that in 2 months Not sure if that's true, the MSI 7790 is $109 after rebate and before selling games (so take another 20-30 off), and can mine at 300k. Less power consumption, less heat, is quieter (fan only at 40-50% at fill 1200oc). These cards are wonderful, have 6 of them. ah, wow yeah, thanks for reminding me... totally forgot about the 7790's... i see one on newegg right now for $110 after rebate.. i'm going to assume games aren't worth as much as a month ago, but should still drop the price to about $70 for that.. http://www.newegg.com/Product/Product.aspx?Item=N82E16814127726that is the 'good' game bundle too.. AMD announced today that it is adding bonus games to the Never Settle Reloaded program as a limited-time offer called "LEVEL UP with NEVER SETTLE RELOADED." The promotion adds Tomb Raider to the AMD Radeon HD 7790 graphics card.
Starting today, this limited-time promotion will run, while supplies last, at participating retailers. AMD expects those retailers to come online next week as they update their checkout systems to support the new promotion. |

thanks guys, guess i'll just run 3 now and get killawat thing to know for sure.
This is the safest route, it might suck to lose 25% of your hashes right now, but that's waaaaay better than losing 100% of your hashes until you have a PSU replacement and/or more equipment! it probably shuts off due to increase in ambient temp depending on how many peripherals are attached to it and possibly moving it to a cooler location, it probably wouldnt even be stressing it too much.. or just do all that and drop the voltage on a card (* if you can on 7950's dunno) |

i wonder how many people go to that p2pool.org site and see all the dead/orphan shares and decide that p2pool sucks?  |

Hey,
Are SeaSonic PSUs any good ? I'm planning to buy a SeaSonic X-SERIES X-1050 for a rig with 3x Gigabyte HD7950s. If there's anyone who uses/used them, please let me know how reliable are they. I would have bought HX1050 or OCZ ZX, but they aren't available locally and I'm not willing to wait x days for shipment. However, SeaSonic X-SERIES X-1050 is available and considering it is single rail and gold certiffied, I supposed it's a good one for BTC/LTC mining with 3 GPUs.
What do you say ?
do the seasonics > 850w ever go on special? the 750w and 850w usually come up on newegg for $75-$100 every month or two i've got an 850w thermaltake 'toughpower' bronze certified PSU i've been using for like 6 1/2 years =p |

7970's would be one of the worst cards to buy purely for mining as well... if you're going to game with it also, sure.
Otherwise you're purchasing a card that's going to decline in value (absolute $) more than any other card out there over the next few months
Are you jusy saying that because of the 8*** series cards coming out or? newer technology always declines in value faster if the next series comes out, then the effect would be even more pronounced right now you can buy a 7850 or 7870 and if you do the rebate and sell the games, then you could already sell the card used and make a profit on it (actually, i suppose the card would still be "new") |

4x7950 gigabyte stock clocks(1000/1250)
gigabyte 970a ds3 mb
2x4gb ram
sempron 145
lepa g1000 1000w psu
i have two 1->1 risers and 2 1->16 standard risers
12.8 drivers
2.8 sdk
cgminer 3.1.0
Everyhing worked fine when there were 3 gpu(2x 1->1powered raiser and one in 16x slot), after adding 4th one(2x 1->1 powered,1->16 in 1x slot, 1-> in 16x slot) rig just turns off after about 15 minutes(sometimes more sometimes less), temps are ok i use autofan with target temp 75 and they all run at about 73 all the time while mining bitcoin. I can't turn it on for a while.I used it for a while with lcd plugged in and don't remember it happening(maybe it was to short time). Psu is 4 rail and i tried to split is as equal as i can:
1:mobo+one card(not modular so has to be i guess)
2:one card, impossible to plug anythin else
3:one card+ssd+powered riser
4:one card+powered riser
only way to determine the rails was a photo of pcb in some review so not sure it really is split that way.
Looks like something with psu for me but how can it be to small for this setup?
well, if it lasts 15 minutes, then it suggests to me that you could probably get it working with ubuntu on a usb stick, take out one of the RAM sticks, underclock/undervolt the CPU (and RAM) turn off all the stuff you don't need to use, like the onboard audio and serial ports and what not |

http://p2pool.hostv.pl/New features: - check GetWorkTemplateLatency - added sorting for tables (just click on table header). - added filter for BTC/LTC/TRC nodes Best, sViruS the GWTL is heavily influenced by max block size.. i.e. the ridiculous 1000 maxblocksize on one of the servers shown will give it a significant advantage over any server that has any transactions. likewise, the 5000 max blocksize on my server gives myself an advantage over 95% of the others but , pls do at least 2000 size, 1000 would have missed two 20+ transaction fees the last week |

Yes, mintxfee=0.0001 is still very low. It's also the new bitcoind default as you correctly state.
I'd go for mintxfee=0.0002 or higher.
0.00000001 BTC = 1 Satoshi 0.0001 Satoshi = 0.00000000001 BTC I think it must be mintxfee =100000 or 200000 mintxfee 10000 is the default that's 0.0001 it was changed in latest version. the relay fee has been 0.0001 for a long time (year+?)... the creation fee was 0.0005... so, was a bit odd. i wasnt going to at first, but too many transactions filled with.. not much. i set the relay fee to 0.0005 (the old creation fee), or 50000 if it's really a problem, if you set it to something like 50001, you'll see much less transactions |

Hi guys, I have priority issue with bitcoind latency and p2pool running with it. p2pool link: lenny.dnsd.me:9332 I have dedicated hardware for running bitcoind 24/7 node and p2pool with it. That's small server based on AMD APU A10 + SSD, was working nicely for months, till yesterday. My bitcoind node is literally flooded by hoax transactions, like this: https://blockchain.info/tx/7227c9d392166fdcd917f39da2def36bcf69b437d90e349d73a48952c0fbdd69https://blockchain.info/tx/292d1d7ff7ece8eb67b4bf3c2f523736679c616fce8216bf37ac23edec6e0e031 single transaction, nice miner fee included (1.46 USD actually), but it have over two thousands outputs and 100 KB in size! It's like a fishhook, whoever will take it, will loose seconds of latency. Bitcoind latency is at ~ 4s right now, for months it was at 0.3s. About 18 hours ago my latency went extremely high up to 7s and till then, network is under attack of these hoax transactions. Exactly same problem has been reported by my collegues at forum.bitcoin.pl. They showed be their stats and same latency issues (bitcoind latency at 3s or worse, like in my case). Latency that high makes mining on my local p2pool node unprofitable. My bitcoin.conf: (...)
maxconnections=30
blockmaxsize=500000
mintxfee=0.00005
How to filter these transactions?  blockmaxsize 500kb would limit transaction max size to 50kb, wouldnt it? so those transactions wouldnt even be included in your block? nm, it'd limit it to 100kb. so those 100kb transactions i see would be included you could lower your maxblocksize to something lower =p |

its a good thread except for one major thing...the dll site tries to install adware on your machine. that is a really bad thing. http://www.mediafire.com/?hlulrwjbk72ldlyshould allow you to download the zip without installing adware. no promises though as I will not monitor the link constantly. update: dude....GENIUS!! thank you for the tip! I've lowered temps on my 7990 malta from 79-86 range to 71-73C....hell yeah!!!!! gpus 925-1000mhz, ram on all cards is now at 300mhz...this drastically reduced my heat...i am running stock cooling too...will post pics soon. i put it at www.nogleg.com/archive/bitcoin.misc as atiocdll.rar i assume the DLL files are legit, i didn't use them myself (just ran through a couple virus scanners) |

bitcoin p2pool
Total 6.80GHash/s --- Dead 1.15GHash/s
Total 18.8GHash/s --- Dead 7.66GHash/s
litecoin p2pool
Total 18.7MHash/s --- Dead 3.03MHash/s
Total 29.8MHash/s --- Dead 10.7MHash/s
how to reduce dead hashrate?
starting from what I think is most likely 1) latency from the majority of p2pool's hashing power to your node 2) latency from your p2pool server to you (<--- and now that i think about it, that would be king. you wouldnt get dead shares from other nodes being slow to you, those would be orphans) 3) running p2pool on overloaded/underpowered server and/or bandwidth issues (most likely upstream) 4) general bitcoind issues 5) stratum some ways to fix ed (adding something and moving things around for more dead share oriented instead of orphans) 0) better internet connection  1) reduce maximum block size, try to do at least 3-5k or so. there was some other block with a +25 fee earlier today that someone with maxblocksize 1000 would have missed. with dead shares and not orphans, this would probably only help if bandwidth was an issue 2) optimize tcp, maybe some tool like tcp-optimizer in windows, ethtool/ifconfig in linux (netsh int tcp show global etc, congestion provider ctcp, all this stuff) 3) if using cgminer, use "fix-protocol" : true, in conf file, to turn off stratum 4) put bitcoind on a ram drive if you have enough RAM (or if you can't handle the whole 9GB or whatever, set dbcache to 2GB or so maybe), also can put some nodes on there with addnode (other stuff that probably wont help with dead shares) 5) if bandwidth isn't the problem, increase the # of default outgoing connections in the source 6) add some "good" nodes with --p2pool.node xx.xx.xx.xx when running p2pool if nothing helps, try someone else's p2pool to see if it's any better. if not, then you're probably better off using some other pool, rather than p2pool w/ its 6 resets a min |

- Mobo : Gigabyte GA-970A-UD3
- CPU : AMD Athlon II X4 640 (using the standard cooler, but got a spare one, same results)
can it run that cpu? some of these boards need bios updates first i had to use some old sempron to update bios on one of my boards to run an AM3 (or i guess that's AM3+?) well, could try taking out the cmos battery for a bit anyway |

Look at all the fortune tellers battling it out. IF you asked someone a few years ago if Bitcoin will go to $250 almost everyone would have said NO. LOL Just keep mining fellas and stop arguing.
Bitcoin isn't at $250 right now. It's not even half that. It wasn't even at 250 for a couple of hours. Don't mine because you expect bitcoins to go up. Just buy bitcoins instead. Lets say I buy a 7970 for 400$ now. It mines at 700mh/s. We have a price of 110 and in one year, Bitcoin goes to 200. Profitability declines by 60% or more. You have 727 dollars when investing, ~ 1500 after one year of mining and not selling bitcoins. Your problem is your profitability is going to decline by waaaay more that 60%. More like 98% or so. You need to take into account: - The 600 65GH/s Avalon machines that will be shipping in batch 2 any day now - The 600 65GH/s machines from Avalon batch 3. - The 200 TH/s that ASICMiner says they will add in the next 2-3 months - The 60,000 plus Butterfly Labs pre-orders, which should add another 200-300 TH. - The hundreds of thousands of Avalon discrete 282 MH/s chips that are being sold. Difficulty will easily be in the hundreds of millions in the next 6 months. 7970's would be one of the worst cards to buy purely for mining as well... if you're going to game with it also, sure. Otherwise you're purchasing a card that's going to decline in value (absolute $) more than any other card out there over the next few months |

Grats on getting up and running. I've hardy ever been successful uninstalling and reinstalling different ATI drivers, most of the time I get the same application error if I do that. Since these are mining machines, it doesn't take long for a reinstall (Win7 64-bit SP1 installed from USB stick, no updates or anything else). I disable windows update and the rest of the action messages, install system drivers, a few utilities (VNC, Winzip, Afterburner, .net 4.0), then install the ATI drivers depending on card (6x gets 11.11, 7x gets 13.4, 7790 gets the custom one), copy my base cgminer and go.
The reinstall saves a lot of frustration. A 450w PSU is enough to drive a single card, anything above that you may be running into power issues.
I only have a single card. I didn't have any luck with XP, and it looks like it just flat out won't work with XP, so I gave up on any uninstallers, and did a Windows 7 install, and everything worked out of the box. The install didn't take long for me, since I just ran it off the Active Directory server here at my work. It's currently running in a company machine, while I figure out the settings and order a license key for my own rig at home, to run it off of. I tried the settings that were posted above, but going for a full 900mhz and 1300mhz RAM. instantly caused a reboot (not sure if it was a bluescreen, or not, because I was running it over Google Remote Desktop. I will play around with settings some this morning. Forgot to bring the PSU with me. I'm only running one card. I was able to run the RAM up to about 1280, but it was unstable and caused the driver to crash. It SEEMED stable at 1233mhz RAM and 898 Engine, @1.1v, but automatic updates rebooted the machine about 45 min. after I went to bed last night, so I have no idea if it would have run stabile or not. More testing throughout the day today. The difference between 1280 RAM and 1233 is only about 1.5khash, so definitely not worth pushing it much harder than it is, if it will run solid with these settings. There also doesn't seem to be much difference in performance in going from 20 Intensity down to 19, except that it too may have contributed to the driver failure when it was at the full 20. Hard to say without more long-term testing. Thanks again for the help, you guys! I may give Linux another shot at home, before I drop $200 on a Windows 7 license. EDIT: Well, crap. It ran for about an hour and a half and the driver crashed, and CGMiner declared the card "sick" but kept running it while very slowly dropping hashing speed. I gave it 10 minutes, and it never fully stopped, or restarted, so I restarted it manually. Is this a driver issue? Any idea what might be causing this? overclocked too much? i've never had cgminer successfully restart a card |

never invite a cop into your home. someone may have left even a small bag of drugs at your place somewhere you don't know about, the cop may find it.
agreed but for the record, i did have two cruisers pull up at 1 am to my house, probably sometime in january or feb? i live in a rural area that's incorporated into a small town (pop 2000 roughly), so those 2 policeman were the two that are always on duty on nights. so the whole police force pulled up (ok, they may have had someone extra working that night, hah) appeared to be looking through my server window (it was like 30o outside or so and it had the fan in the window blasting in, etc).. so i opened the door and asked what the problem was, and apparently there was a 'chemical smell' wafting from my house, that they could smell from about 200 yds away (the main road) but i forget myself when they're actually there and present, so, yeah, i invited them into the house. they saw my computers and left. took about a minute. though in hindsight, i wouldnt have let them in |

liqpay is not an option right now, or I am a dumbass maybe both...
Yeah I don't see any way to use liqpay with BTC-e, and bitcoin-24 had their bank account seized. Anyone know of a way to use liqpay? well, i'm sure there are probably half a dozen or more shady exchanges that provide liqpay->perfect money services alas, i have no experience with any of them |
