It's called atmospheric pressure/air density.
At higher altitudes there are fewer air particles per cubic centimeter.
Thus, more is needed to cool the same amount of hardware and the fans will run faster to achieve the same amount of cooling.
The whistle from bitmain devices is normal. These aren't meant to be quiet, they are meant to be efficient.

Ignore the "Stick to the big 3" concept when considering what coins to mine or multi-mine.... too many people are closed minded on this nowadays and only follow each other like sheep in a flock. This concept people constantly spew also only tends to point people at AMD cards; which; honestly... I haven't seen a reason to personally invest in any of them as of yet after quite some time.
You can mine almost the entire list of algos on zpool without using any 3rd party monitoring/mining apps; The pool will switch your algos for you if you set up your password string properly/use my batch (modified to use with your miner app of course since you are running AMD). The pool will auto-switch based upon many factors, and they also payout all coin rewards in your selected payout type (such as BTC, or any of the alts that the pool mines).
If you wish to get help setting up an AMD specific script like my nvidia one that I have in my sig; I would only need you to provide me with a basic list of information to make it happen... it just takes time to get the hashrates for each algo.
Nobody ever worked with me on making an ATI side of my batch, so it never happened. Most people were always lost anyways when it came to the Nvidia side which I know pretty much like the back of my hand.

so heres the numbers i found for Lbry
rx 470 - 80mh/s
rx 480 - 105mh/s
gtx 1070 - 290mh/s
750 ti - 50mh/s
if numbers are correct well nvidia got upper hang.
although dual mining with rx cards is possible.
Also for reference, here's a zpool benchmark of my Asus GTX 980 which i have seen recently on CL for as low as $200 ea: ASUS GTX 980 SM 5.2 HWID: 1043:8518 Hashrate: 177.884 MH Intensity: 24 Freq: 1278 Watts: 179 ccminer/1.8.3 win64 CUDA 7.5 369.09 sorry, i didnt take any wattage readings. This reading is from 3 months ago. The wattage reading is computed through the miner via knowing device TDP I believe... or the CUDA device can return a value.. (i'm unsure which) |

Hmm, I have some old RasPi's courtesy of the now defunct AMT dating from early 2014, prolly version-1's. Will the software run on them?
A solid maybe? Try it out and leave feedback here. I believe that all versions of raspbian works on all version of raspberry. working with RPI's enough, i'd have to give a solid "yes". Just install a fresh Raspbian image, run: sudo apt-get update
sudo apt-get upgrade
sudo raspi-update (might need to apt-get this one, sometimes its not included, it wasnt on my latest RP3 image I downloaded) Should work just fine IMHO =) The builds of raspbian have usually been pretty consistent across models and versions of raspbian. |

Yeah, I figured it was some sort of DB error or something that caused this to happen. Was mainly curious if others have the same sort of errors happen to them now and then.

 That number made me laugh right now.... yet still pending. It's only 22 min old, but that many confirmations already?!?!?!?? |

xevan is pretty good... there's a few coins that use that algo as well. I have been using it on my CPU's for a while now.

FWIW...
If you ask me, the PNY brand has always been sub par...
I've always had issues with their products, weather it's build quality or whatever else. I don't buy em. Keep it in mind.

Excellent!
Might I suggest adding a note for Raspberry Pi users that is is EXTREMELY HIGHLY suggested to use a powered hub and not the Pi's USB ports directly.... They have trouble even supplying enough current to a portable USB self-powered HDD... let alone a stickminer =) I don't want to see people with unnecessary troubles related to this =)

Me personally, I don't do any coin trading.... soo unreliable..
I also don't like holding wallets and bunches of blockchains for them to be able to spend when they need spent.
I always work with autoexchange pools. It's simple, and effective. Now and then I feel the pumps by an increased exchange value, and other times I find myself looking at the profitability of other algos with 24 hour tests to see if the payout is more consistent or greater. The estimates shown on sites are just that; estimates. They tend to be pretty far off off in many instances due to exchange price fluctuations.
All in all; I love being able to have a single payout coin that is stable and reliable, while at the same time I am mining multiple coins over multiple algos with machines; using auto-switching pools.
For instance since I use Nvidia cards heavily, I did do the early lbry mining, and decred as well. Turned some good profits; but when they died off or pool hashrate got too low for network diff, back to Lyra2 I went. Much more profitable. Then people started switching to ZEC, ETH, and XMR... and the lyra2 pool hashrate took a dump. Block payouts were less prevalent and thus less consistent; So I went looking at other algos and, to my surprise still keep on turning about the same amount of profit/day that I was months ago.
Relatively close anyways when converted to USD.
When it comes to GPU mining; just remember, they are versatile. Very versatile. And if you want to expect to sell and upgrade; take your purchase selection into account. Nvidia's seem to hold value and keep a higher resale value. The market towards gamers and such is much more present than for the AMD equivalents.
Seeing $200 980's on CL makes me tempted to build a new Maxwell rig... but that extra $100 will bang in a 1060.... which is far more hash and almost half the power.
Choices... choices...

Was thinking of putting around $5000 into alt-coin mining with a gpu rig and I live in an area with pretty inexpensive electric. Wanted to know if it was still viable, even with electric prices around $.03 or something like that? Might be able to get it free with a family member who has solar panels on their roof, so yeah.
Thanks!
$5K into 2-3 rigs would be ideal. They will still turn a profit especially if you are going for RX400+ or Pascal++ GPU. Don't find yourself limited in mentality like a lot of others here: There are HUNDREDS of altcoins that PROFIT... you just have to configure to mine them (pool or otherwise), nd exchange or auto-exchange through a pool to something like BTC. Don't sit there thinking there are only 3 profitable options, because there aren't just 3 like the fanboys that seem to only follow each others' steps do..... I make a decent profit not mining XMR, ETH, or ZEC...... I have always shied away from them each time I did a profitability comparison between my multi-algo switching, or one specific algo for a period of time. |

im assuming you have one 110v 20A circuit at your disposal?
I suggest just buying enough second hand newer gear and building a 4-5 card rig.
smartest option right there.
One S9 and you would melt the circuit.
One R4, and you cant really run much else...
but hopefully you find an avenue as per all of the above.

Hi all, I am in the great situation that I have an electricity flatrate. But I donīt want to run loud mining hardware in my flat. I would like to use my GPU for mining. I soon realized that I can forget BitCoin mining. Then I tried Ether mining but found out that my GPUs memory is too small for the current DAG size. I have a gtx 460 with 1 GB video RAM. Is there any currency where it would make sense (=profit  ) to mine with my GPU? I am looking forward to hear your ideas! Thanks in advance. FYI the 400 series was the most power-hungry of any GTX series card if my memory serves. I used to have a GTX 480 running x11evo; would be 80* solid (liquid cooled cpu and GPU); and the machine (with CPU mining also) drew over 600W.... not something I let run for long... a $40 antminer S3 generated more profit and made a lot more sense since I could run 2 of them. Look into the "other" alts that you see on pools that do multiple algos/coins per algo like zpool.ca Link on my sig I believe. That's if you want to mine with your card regardless. The trick is getting a miner that's compiled with an instruction set that works on your GPU. I was able to mine X11 on a GTX275 not long ago... but I just wanted to see what the 240 cuda cores would do in relation to my 700/900 series cards. Took a while to find a miner that would see that video card. only expect a mind numbing trickle of profit from that card; it will most likely cost more for the electricity than it mines in the end. |

As a kid I knew the guy whom did the first pcmcia to isa/pci adapters.... A crazy mess of wires...
I would have to study the PCIE port hardware from the 1-3 splitter and find a way to interface with that via some sort of USB/TTL I would think.... Seems complicated since I don't know the hardware aspect of both well enough.
Might be an idea for a open source community side project of sorts... Lol. I'd be willing to do some research and put effort in where I can.

phil i was thinking a usb option to possibly try with a raspberry pi cause they do not have pcie
This was the ultimate thought here as well. But the universal nature of it would be sorta sweet =) If you wanted more bandwidth, just do multiple connections and split traffic. |

A true PCIE-USB would be ideal for universal compatibility.
Kinda like the pcmcia pci adaptors were a niche thing.
I wonder how many display adaptors you could 'data pipe' through a usb3.0 plug...
Imagine a USB miner with simple driver the. People use their favorite os/miners.
No hunting for 7gpu capable boards. Just a box with power and a USB hookup.

Baikal miners is made for pool mining not for solo mining.
If you want to make solo mining, create your own pool.
I responded to a pm with this info in slight more detail. It works the same solo or pooled. It mines. Share reward freq is what you are referencing; which is not what he's specifically asking for (solo). |

Presently on my dedicated miners I install the windows 10 freely available ISO, and install it, run DWS, and never activate windows itself.. I don't care that I can't customize my machine or disable that watermark; I don't even plug in a terminal unless I need to admin it for some reason.
Uptimes are impressive, like 7 was on my last machine....
I have had lots of success with 10; especially after getting DWS. Just make sure you un-block some of the domains added to the hosts list as to not nerf Skype if you use skype. Skype is now dependent on some IE/edge libraries/servers. I am almost about to switch COIP carriers because of this. I don't like leaving a telemetry port/site unblocked.

Try mining magicoin (XMG) , i used core i7 mining xmg perday get 10 - 20 xmg but rate now just 20 - 40K satoshis perday , or you can try using VPS for mining xmg
Ive had the best results with xevan recently. XMG didn't pull the same profits. (I use an auto-exchange pool) what pool you used, maybe i can try for mining xevan I use cpuminer-opt 3.4.11 There is a core i7 build that works well with those CPU's. |
