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
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  |

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.

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. |

Porsches are fun I have owned a few and never regretted the purchase at all. Just don't buy a boat God forbid:)
Why not? Oh no, donīt start with "boats". Thats an endless story ! wait.. dont you need a boat so you can have a "boating accident" for tax purposes?  |

Is there a special trick to get the ONDA B250 BTC-D8P MoBo Ver.1 to work?
( Note: I'm getting the same symptoms Storx described on the 6 slot ONDA. I tried clicking the the button he used to resolve the issue. No luck)
Do I need to install a VGA driver or something else?
Is there an online manual ?( I couldn't find one of the ONDA website.)
Been struggling for 2 days with the ONDA B250 BTC-D8P MoBo Ver.1 MoBo. Ran all over Toronto to replace RAM and CPU. Sill not working.
Here's my set up:
MOBO : see above
PSU: CORSAIR HXi Series HX1200i 1200W 80 PLUS PLATINUM
CPU: Intel Core I3-7100 Kaby Lake Dual-Core Processor Socket LGA 1151, 3.9GHz
RAM: G.SKILL Ripjaws Series 4GB 260-Pin DDR4 SO-DIMM DDR4 2133 (PC4 17000) Laptop Memory Model F4-2133C15S-4GRS
GPU's 1 x EVGA 1060 SC, and 7 x EVGA 1060 SCC
I plugged it in the way Phil mentioned so that i didn't short it. I even tried what worked for Storx ( pushing the CMOS button) when he had trouble getting his D1800 to post.
not sure if this will help.. have the onda B250 D8P ver 1. G4400, 8 gig ddr4 sodimm (g.skill ripjaw ddr4 2400), 128 gig msata. dual psus, mixed amd and nvidia, 6 cards total. for initail setup: i booted with a single rx460 and got into the bios. in there i set the iGPU (to use the G4400 Pentium) as the primary video to use the hdmi port, then disconnected the 460 video (left the card in though) and rebooted. from there i installed win10. the iGPU came up as "microsoft basic vga" or something to that effect in device manager. then i let it search for drivers and it grabbed the intel driver from ms. from there is was a cakewalk, more or less. the board does some sort of self discovery mode on initial boot and any boot after a cmos reset. in a bios reset i think it expects a card in the 1st slot (closest to cpu) and doesnt use teh iGPU (if any), its kinda of a weird board until you get it setup, then its fine. its actually rock solid for me. i like it, cards have good spacing and cooling is good with 3 noctua 140s each pushing 133 cfm at them. EDIT: i have looked for documentation; cant find any Thx. I have a couple G4400 CPUs on other MoBos. I'll move one to the ONDA and start over. Fingers crossed. oh and i did have the 3 molex and 3 sata power connectors plugged in during all this, max of 2 connectors per psu string, even when i just had the one card. mobo atx, molex and sata, and 2 cards on one psu. used the other psu just for pcie on the cards. |

I have a question about using Miningpoolhub's auto exchange feature. If I am mining 2 different coins and having both auto exchanged into BTC, does it store all the BTC together, or are they in separate wallets? Basically, I'm wondering if I can withdraw the BTC all together or if I need to make 2 separate transactions.
i would be interested in this as well. i used nicehash, luckily i had been paid out a few days before so im only out 40-50 bucks. set mhp up with eth (amd) and zec (nvidia) but the way its set up there is not very intuitive at 1st glance. i think i transfer coins out of the eth and zec wallets to another wallet that then exchanges to btc? i havent found a spot to enter a btc addy, but maybe thats done when you convert? |

nice info, thanks. i am slowly adding nvdia to my onda rig, so this is a great starting point for me. |

Spending is easy. Just use the sweep option of a mobile wallet. In Mycelium wallet, tap the 3 little dots in the upper right corner and choose "Cold Storage".
This will allow you to transfer all the coins to your wallet app. If you don't want to spend all your coins immediately, you can transfer the remainder to another paper wallet.
This is why I prefer to keep my coins in many wallets. You can sweep a wallet with only as many coins as you want to spend or feel comfortable carrying in your phone.
with the mycelium mobile app you can also sweep from paper wallet directly to another wallet, not just into mycelium. for example i swept a paper wallet directly to my trezor with it when i was splitting bcash out from it. |

Needless to say I was pretty happy. Oh and Windows isn't sticky and unresponsive anymore. I've now created a system restore point. Tonight I'll proceed with the installation of the Vega's.
whenever i make a change and am sure the system is stable i make a full disk image using macrium reflect free. its saved me a few times when something goes south after updates or changes. its free, makes a bootable "rescue" iso that you copy to usb. boot the rescue usb, then just restore the image (thats saved on a different usb/partition/network share/whatever) and away you go. https://www.macrium.com/reflectfreei use it on all my rigs. miners, laptops, daily drivers, everything. |

Never never never never sell btc for paypal.
The buyer has 6 months to scam you no matter what you do.
I don't know why you won't use coinbase but if you have never used coinbase and don't have an account setup thats a reason.
With coinbase sells sell under 1000 usd two or three days in a row. You will be fine.
Never do a big coinbase sale send receive or pruchase. The ruling handed down this month for IRS access to coinbase is simple:
any 20000 dollar move of any kind
a sale for fiat
a purchase for fiat
a send
a receive and Coinbase has to send all your records to the IRS from 2013 to 2015 not sure about 2016 or 2017.
So to be safe do under 0.75 coins in a move and don't do 3 moves of 0.75 close to each other.
sales of 1000 usd are not close to the ruling.
i give my accountant my coinbase records every year anyway for tax purposes so i cant see the point of trying to stay under any particular amount in any given transaction or time frame (well aside from wanting to stay in a particular tax bracket). and how else can you easily cash out a large sum whenever there is a good price you want to lock in. legally i mean |

If you don't hit a block while solo mining, you're basically wasting your power right?

Just to clarify what are the ram options for the onda 8 gpu board ddr3/?
What all needs to be hooked up and what doesn’t
it varies depending on the board. the onda b250 d8p takes ddr4 sodimm. positive on this as i have one. the onda 1800 takes ddr3 sodimm.. i think. someone who has one will chime in. not sure what you mean as what needs to be hooked up and what doesnt. the various boards have different requirements as to power connectors and such. for the b250.. power: needs 3 molex, 3 sata, a 24 pin atx and a 4/8 pin cpu. for storage it has sata and msata sockets. cpu is socket 1151. ddr4 sodimm for ram. |
