do you guys run your different nvidia gpu classes (ie 1070 class, 1080 class etc) on different algo or switching strategies? like 1080tis are better/worse than 1070tis at some algos? i have 2 470s and 460 that stay at eth on mph, and at the moment my 3 nvidia (1070, 1070ti, and 1080ti) are lumped together as one worker and all mine whatever i choose at mhp. should i split the 1080ti out and run it as its own worker and let it run independent? whattomine seems to suggest that but it varies and from what i gather its not the most reliable thing there is. jeez life was easier when i was all amd  but i retired my 380/390s and i must admit playing with the nvidia stuff is kinda fun. I just got my 1070tis and I intend to run 1080ti and 1070ti differently. 1080tis are dedicated to coins that show linear scaling with cuda cores like vertcoin, skein. Occasionally switch to equihash if there's a pump. 1080ti just don't scale well with equihash. 1070ti probably equihash because it's way more efficient and better price perf in that algo. Though I will switch it to 1080ti's coin if there's a shitcoin pump. yeah thats the way im leaning too. the 1070/1070ti as one worker, the 1080ti as another. the 1070s for their efficiency, the 1080ti for its grunt. thanks for your thoughts on this. |

Another question.
I got a 2400W server psu along with a 750W psu for a 12GPU rig.
When my rig dies for some reason, does not happen too often, but when it does, the server PSU keeps the GPU's running.
Im looking for a way to get around this problem, any ideas?
depends on how good you are at diy electronics. one way is you can use a relay to control the 2400. a 12v output on the 750 powers a relay that the 2400 is plugged into. but relays that control that amount of power may be hard to find? you would want something that can switch 3000 watts at 240v (i assume the server relay is on 240v). so 15+ amp 240v relay with a 12 volt coil would do it. make sure you use a big safety margin. another way is maybe the server psu breakout board has an on off toggle switch? much easier to use that as its low power. same deal relay powered by the 750 opens/closes the power switch on the breakout board (NOT the switch on the server psu itself). that can be a much lower powered relay as the switch on a breakout board hardly handles any power. but check with the maker of the breakout board. a slightly modified add2psu style relay might be able to be used it this case. the add2psu would connect to the server psu breakoutboard switch contacts. |

Are we rich AGAIN?
Yeah. *sigh* i know. boring isnt it? |

you can use the multi-algo ports so that MPH can choose the most profitable coins for you - this was you dont have to check whattomine all the time. From there you can also select what coin you want to be paid with - using MPH auto-exchange feature.
I wish MPH had a better page where I could monitor my rigs if I'm mining different coins unless I'm just not seeing it. Been using MPH for a while, don't think this exists. im on mhp also, still playing around with it. for different cards it looks like i will fire up different instances of ccminer (or whatever) as the 1070/1070ti will be better at different coins than the 1080ti. i guess i pick the algos the card is best at from the autoswitch drop down for that card series. |

the red foam protects mobo from static I like this idea as my winter humidity drops under 30%
isnt that red foam anti static? if it is then its mildly conductive, which gives it its anti static properties. not really recommended to be in contact with actively running electronics, although lots of people have done it. VERY mildly conductive, commonly measured in megaohm / square inch ballpark. Probably not an issue as isolation for a computer motherboard. probably not, but i always tried not to. i usually used pizza boxes for temp setups always meant to grab the fluke and measure some of the anti static foams i have saved as some may be more conductive than others, but never got around to it. take like 10 seconds. its on my bucket list.. |

having a background in medical, i think that something like secure decentralized medical records is a good idea as one of the problems in healthcare is letting practitioners access records as right now there are so many proprietary storage systems that practitioners cannot get the info they need as its on a system they do not have access to. even then sometimes formats are not compatible with a practices existing software so examining it can be time consuming and problematic.
but if this takes off the storage requirements could grow to staggeringly huge numbers as imaging (mri pet ct etc) in particular gets more complex (ie file sizes grow). so forgive me if this has been answered but is this actually realistic? how much storage can this scale to? not the blockchain that stores the hashes but the storage of the actual patient data.
The actual volume of storage is not a limitation. Storage is cheap and it's only getting cheaper. sure its not a limitation in theory. the hardware for the storage is doable. but where is it stored physically or is that not decided yet, ie have any datacenters or whatever been chosen. whats the game plan for expansion, backup, throughput? any testing done? |

Know what massive wealth doesn't protect you from? Toothache.
Memento mori.
just buy a dental practice and the staff to keep it open for you 24/7. |

Decent card other than the JUNK fans. Cooling isn't noticeably better than the 2-fan EVGA SC model though. i plan on running it at a fairly low powerlimit so hopefully the fans wont need to work too hard. we will see. |

i used some plastic washers from the hardware store to lift the mobo from the wood frame, then used wood screws through the mobo mounting holes to secure it. i do need to figure out a better way to secure the psus instead of zip ties though Most hardware stores have some fairly small "shelf reinforcement" right-angle brackets of some sort. I think I've even seen some usable ones at Walmart. I've also seen "clips" apparently intended for automotive use, that have a "threaded" hole one one side and a small non-threaded one on the other side - the "threaded" side tends to be fairly large, #10 on the ones I'm planning to use, but the other side hole is suitable for the #6 screw to pass through and go into the PS itself. Try Ace and possibly other larger places like Menards, Lowes, Home Depot, for those. perfect, thanks. |

Phil - can you show how the fans are secured on the wooden rail? Thanks
Fans attached a long wire tie in the back of the 2 fans then up and over the center gpu  heres another way, drywall screws through the mounting holes straight into the wood.  |

Inspired by crazydane I built this last night
uses a 21 by 21 inch plywood board.
the red foam from the mobo packing to lift board and prevent static discharges
some stainless steel brackets to hold the corsair hx1200i psu
two scythe fans for cooling the three center cards
I have asus 1080ti ----msi 1070ti ----evga 1070ti --- msi 1070 ti ------------- waiting on a msi 1080 ti

yes and no (heh)
by that i mean when i did sell, it was cool because when i did it was usually for a good enough reason, toys i really wanted, vacations, gifts. and years ago it was to promote actual use of btc.
but.
when i look at how many btc i had vs what i hodled.. well.. damn. spent many millions of usd worth of btc at todays prices.
oh well, no regerts.

Ok, Litecoin has just surpassed bitcoin for the 24 hour total dollar volume on worldcoinindex.com
We are officially fucking nuts.
yeah i pulled up my coinbase dashboard this morning and had one of those "wtf??" moments. i wonder if part of it is all those new coinbase accounts buying ltc "because its cheaper" things? or perhaps now that btc has futures and big wall street money is now in so the old btc price manipulators cant compete with the wall street deep pockets.. so now ltc is the coin to manipulate for "regular" crypto folks? |

That's a very good idea and a cheap solution too - to ensure that cards are lined up standing correctly and with 3 fans mounted like that.
Whats the dimension like -- I will do some experiments this weekend. Thanks for idea.
The aluminum angle stock is 1/16" thick by 1/2". 3x 120mm fans measure 360mm across (duh) (about 14.25") so that would be the length to cut the aluminum stock at. I cut mine a little short since I was only going by what was needed to support the GPU brackets. To precisely mark the holes for the GPU brackets, I held the aluminum stock in place underneath the GPU bracket lips, and then used a permanent market to mark for the holes through the oval holes in the GPU bracket lips. I did a similar thing for locating the holes for the fans. Btw, I never did shut down the rig while doing any of this. Did want to loose the hashes, lol. It's a nice way to straighten up the cards... but the fans don't do much for airflow, as they're placed just in front of the GPUs' exhaust fans. Ideally those 120mm fans should be placed behind the GPUs to help blowing cool air onto the backplates, I reckon... i wound up putting 3 140 mm Noctua 133 cfm fans along the back of the gpus. i also added a 4th fan, an old antec low airflow 140 because i had it and just stuck it inline with the cpu. not really needed. the fans are hooked to a scythe fan controller, i wasnt sure how loud the fans were and i want this build to be as quiet as possible. its in the basement so noise isnt a problem but i just wanted a quiet build, well, just because the cards run very cool but the basement is around 65 F. heres pics of my setup, for no real reason.. i used polplar wood for the initial frame to see how it all fits, ill probably go with metal at some point.   and the hash rate etc. still dialing in power and stuff. on ewbf gpu0 is a 1070ti, gpu1 is a 1070.  . |

A big thanks Storx. I started out with DDR3L 1600/1333MHz 1.35 volt as that's what Onda states on its website: http://www.onda.cn/MotherBoard_Specifications.aspx?id=373I then went to DDR4 SO-DIMM DDR4 2133 1.2 volts. It's the same one vapourminer used - but only 4 GB instead of 8. I can barely read the etching on the RAM slot but it looks like: DDR4 ST12V P (or D) R (or 4) 1710. Cheers I actually had this exact question thought I had the ram I needed but I definitely don’t @phil what ram are you using for the onda This is for the board you sent me Anyone have a link to ram that will definitely work?   What connections needs to be powered and what doesn’t? // all these sata and molex? for the pictured board, the onda B250 D8P ver 1.0, here is the exact ram i bought, runs great. https://www.newegg.com/Product/Product.aspx?Item=N82E16820232153G.SKILL Ripjaws Series 8GB 260-Pin DDR4 SO-DIMM DDR4 2400 (PC4 19200) Laptop Memory Model F4-2400C16S-8GRS i also plugged in all power connectors: the atx mobo and 8 pin cpu (duh), 3 molex, 3 sata even when i just had just one card in setting it up initially. card was in 1st slot closest to cpu. other stuff was standard: G4400 cpu, 128 gig msata. |

I have a couple G4400 CPUs on other MoBos. I'll move one to the ONDA and start over.
Fingers crossed.
Well changing to the G4400 didn't make a difference. Just like before, The fans on the GPUs and the CPU start spinning and nothing else happens. Not even a light on the Ethernet port. So, I'm giving up and sending it back. Am looking at alternative boards ...but likely have to go with risers. crap.  i never really had problems with risers, but i like the simplicity of these onda boards. very clean setup. |
