Looking for some advice, I'm a little confused on how to best cool a farm of open air rigs on shelves.
With an open-air rig of non-reference GPUs, should I be pushing cool air over the rear of the rig and pulling hot air from the front where the GPUs are? Or is it the other way around?
fan >>> rig - gpu >>> fan >>> @ talking dreams xmr on the cpu and zec on the gpu check your watts used vs your hash rate |

Maybe it goes up |

I haven't bothered to run the numbers lately but, it's panned out fine as greater returns than converting lektrik. |

I usually pick a shit coin 2 or 3 times a year and buy a few hundred in usd worth of it. Say buy something at 0.00000050 btc list it at 0.00000500 and look at it every 75 days lets say it went to 0.00000100 Id' sell it for the 0.00000100 and take a 2x profit,but mining any shit coin on the cheap getting a few hundred coins and listing at 10x the price can work too. |

Recently; I don't spend over 10 sat.... unless the short and long term graph is promising (movement both ways). I have before, but I don't anymore really.
I'm not in it for the short term big gains, I am long-balling it.
If I see a coin for 1 or 2 sat; Ill look at it; see what the exchange's traded supply is; (If there's a 40BTC wall at 2 sat, never will I ever touch that for example)
And I will also look into the premine and coin supply of what I want to buy (when spending over 0.001BTC). If I am just spending 0.0001-0.0003 Ill take it on chance without doing research past looking at supplies on the exchange and trade prices/volume.
So far I have done surprisingly well; No giant profits, but then again, no giant investments either, as I have only started to divert my signature funds, to use on yobit's exchange instead of xfer to my main wallets.... so no loss.... ever.
I have made two bad purchases; one was a coin that just has slowly fallen off (5000sat at time of 4mbtc purchase), and another that is slowly dwindling to this day. The first one I got paid back (break even) as it got a pump again one week after dropping... so (hopefully) the next pump, I should sell off those coins for an order that i'm almost sure will go through.... long term, and the other, if I loose the 0.001btc, oah well.
No huge loss.

Even fan-type cards exhaust a LITTLE air out the back of the card, just not as much as a blower-style, so you want to work with that flow and bring air in from the front and exhaust it out out the back. |

You're touching on why I don't really try to mine like you, and continue to trade instead. I have 'shit' coins that were worth WAY less than a fiat US cent on my original buy. I traded the waves so many times that I now have several with negative cost basis and more coins than originally, one pressing bitcoin daily volume now. Ignoring the fun math problem I'm up WAY over 10x on one that is nearing bitcoin daily volume now. I'd love to build those rigs like you, seems like great fun, but I'm trying to buy my freedom now and retire way early, that's my priority. Crypto trading does take a risk-taker\restraint mix for sure though, to watch the wild swings down and right back up that can occur daily and not react when it would break your trading strategy. I wish I'd started earlier though. I'd been looking for my 3rd career for a year when I started trading daily, it was way down low on the try list, unfortunately. Learning to hobby mine various coins was a great way for me to learn more about how cryptocurrency works though. |

Hey everyone... I am planning a re-build of my first mining rig. Currently, it's 4 MSI 470's on an ASRock x99 mobo with an i7-6800k & 16GB of RAM. Obviously, those higher end components are not not being optimized by my mining opereations, so I am going to use that core Mobo/CPU/RAM to build a new personal/music production PC.
So, i have a Biostar TB85/G3258 CPU/8GB RAM + 1200W Plat PSU ready to go and 2 more MSI 470s arriving tomorrow for this re-build.
But, here's the issue... this rig with 4 GPUs is not able to dual mine ETH + DCR. Since it runs ETH only and XMR flawlessly and there is no power headroom issue (1KW PSU), it seems likely that there is a "problem" GPU that can't handle the extra stress of dual mining. I have a good idea which one is likely as it has never been able to do more than 1850 clock speed, while the other 3 can easily do 1950. What I would LIKE to do is identify for sure which one (hopefully only 1) is causing the problem and move that to my new personal/music PC since I will only be single mining ETH or XMR on that overnight or when I'm not using it for music production.
So... the question is... how best to prove which one is the "bad" one. I think the best way is to do a negative test, meaning running 3 of the 4 cards only and seeing if it can dual mine without crashing. But, I am not sure how to do this, other than literally unplugging the GPU, which I would prefer not to do if possible.
I thought I remembered that Claymore's miners allow to turn off any single (or multiple) GPUs but i looked through the instructions and didn't see this mentioned anywhere. I could have just missed it but wondering if anyone here knows how to do that? If so, is it something done within the .bat file?
yes in the .bat file let me look for it. this post: https://bitcointalk.org/index.php?topic=1433925.msg14501372#msg14501372-di GPU indexes, default is all available GPUs. For example, if you have four GPUs "-di 02" will enable only first and third GPUs (#0 and #2).
Use "-di detect" value to detect correct GPU order for temperatures management (requires non-zero "-tt" option); note that it will not work properly if you do not want to assign all GPUs to miner (add "-gmap" option to fix it).
You can also turn on/off cards in runtime with "0"..."9" keys and check current statistics with "s" key.so first do -di 0123 should crash then do -di detect figure order out. then pull away a gpu at a time. to figure the bad one. -di 012 no crash means 3 is bad Hey Phil.. thanks for this! I was able to identify the "bad" card... luckily by just de-selecting it at start-up in run-time... so i didnt have to mess with the bat file at all. Sure enough, when i turned off my suspected bad card, that rig ran fine on ETH+DCR for quite some time, so that that was indeed the bad one. I have it set aside now to use in the build if my new personal/music PC and got the new Mobo/CPU/PSU/RAM up and running now with 6 MSI 470s. Still having a bit of trouble getting it to do ETH+DCR but it's been running ETH only solidly now for most of the day. So, that now puts me at 24 GPUs with 24 pushing 640 mhz ETH, plus getting about 12 Ghz DCR with 18 cards, hoping to push that to 15 once i get things figured out with that re-built rig. I've got 1 more new 470 coming tomorrow, so will have 26 total 470s in the end. I will either mine ETH solo or XMR with those most of the time as they will be in a full tower chasis and I don't want to push them too hard and keep the heat down. I know i've said it before, but this will really be the cap for me. I had a good test run heat wise last week and my A/C couldn't keep it comfortable with 4 rigs running... not even close! I need to get someone out to do maintenance on it and assess if it can be fixed or if I need to go with a bigger unit. Hopefully that wont be the case. |

I am heat capped at the moment. 2700watts is all I can do when it is 55f but 55f for may is great. on June 1 the power goes up I will be moving gear around. to the solar array coins are over 1700usd! |

Sorry, trying to catch up on the thread...
Did we figure out whether there's a way to strap/mod the memory timings of 1070s/1080s?

Anyone ever faced GPUs dying due to risers ?
Since a month, I had 3 GPUs died on two rigs. The two rigs are identicals.
I changed the PSUs and the GPU's after 2 death , and the only remaining parts were Mobos and risers.
And then the 3rd died.
So I think the risers could be the cause.
These are risers with PCI-e 6 pins power. (1 month old)
What is weird is everything is working perfectly, and some time I notice the rig is down, and after reboot I see one GPU not working (not recognised , no fan spin) ...

Phil, Gabry, if y'all can do this comp tech build stuff you can likely get your freon card for AC to buy legal and check and top off\service older residential units with freon (R-12 or 14 I think) and add a gauge purchase and vent thermo, metal tape, and bathroom scale and learn to do your own AC top-offs maint DIY. It isn't hard, open book test, little study to do it <good enuf>. I remember something silly like 25$ fee and cert never expires. I check and sometimes top up 4 every year, very small leaks that add up and decrease efficiency, and thus AC power costs overall. Mainstream Engineering Corp, section 608 Type 1 cert I have this book https://www.ebay.com/p/?iid=262969633057 You can read some there and read the HVAC forums full of asshats and build some simple estimation rules that I have on a 4x4 yellow sticky. We get hot as hell here in summer hundredish or more in July. I can almost alway score 2+ degree decrease vent temp every year when I do it. Makes a big difference, as does cleaning indoor outdoor coils\evaporator, but inside coil is kinda hard so I just run better quality return filters mostly on that . My card is 23 years old, now, think I've had an HVAC guy out once or twice in all that time. Sent one away for trying to sell me a $500 squirrel cage fan install that I did myself, overnighted for like $100 and 2 hours time replace. The outdoor motor units that blow heat off the compressor are as cheap and even easier, I actually keep 2 backup new now as they fail most often. All units are over 14 years old, cool 2000 sq ft for avg $220 month lektrik yearly (half duplex). Other north side half with 2 units barely runs as I keep it lots hotter unoccupied. Crap insulation too, 1975 and flat roof. I can provide some more info if you are interested, I'm smack in the middle country hot zone. But 4 am here is a skosh past my bedtime. Night for now. |

lower clocks you dual mine if I recall stop it on 1 rig and see if the risers last. |
