RIG ON SALE HERE!! --> https://bitcointalk.org/index.php?topic=4500313

Hello guys! :)
I'm starting this thread because I want to keep trace of my work while building a 600 CPU cores cluster able to CPU mine VeriumReserve, render some works and other stuffs.

Concept of VRC/VRM is really impressive, especially the ASIC/GPU resistant algo and the unique binary chain, and I still think both are undervalued and only few peoples really knows what's going on with this coins.
(VeriumReserve main OP can be checked here --> https://bitcointalk.org/index.php?topic=1540023.2500;topicseen)

Initial investment, for me, it's huge. I mean, I work as an IT Technician and I'm 21. Pulling out 5500 € to build up something like this it's not easy. I'm not a rich guy, no rich family, nothing. Those are 5 months of wage spent in something fun, and maybe profitable too.

I've already have experience in this sector, my first mining rig was a 24 Odroid SBC's. Here's the reference, in the Italian channel.
https://bitcointalk.org/index.php?topic=1886674.0

Stop talking now! Those should be the final specs of "Sally". (Yeah, this will be her name)  :D

Sally will be encased into a rack, SBC's are odroids based on the XU4 model. (ameridroid is a cool website if you are searching for SBC in the United States!)

• 600 CPU CORES (downclocked at 1.9Ghz each)
• 150 GB of RAM
• 600 GB of space (8GB/sbc)

Internet connection will be provided by a single Odroid XU4 connected via WiFi to my router. Then, every other SBC will get wired connection from it.  ;)

Cool and useful references can be found here if you wish to build up something similar: https://steemit.com/@birty (Thanks to Birty)

Second little disclaimer: English is not my first language, sorry me for any typo mistakes in advance!:


I'll try to keep things updated!
Thanks!

There are 34 shipments incoming, 3 of them just arrived. For now is just a bunch of cables, ethernet plugs and a ton of Coolermaster fans.
Those little babies should be able to keep everything cooled and nicely going. :)
The plan is wire those fans behind the boards. To avoid cutting the 3 pin plug, some female connectors are already on the way for a custom rewire of everything.

http://i64.tinypic.com/73ovm0.jpg

For power, a single 12V 50Watts PSU should do the job :D
Also amazon was a piece of cake, offering me a network kit (even if it's a shitty one) for just 5 bucks...added to the cart  ;D

http://i64.tinypic.com/9qihl1.jpg

This is 75 Odroid XU4 8 core systems to give 600 core total? Why do you downclock to 1.9GHz?

Yes, we're talking abount HC-1 modules. Well, downclocking them helps against thermal throttling at first.
Second is just about power usage.

The Samsung Exynos5422 processor comes with 4 big cores and 4 little cores.
First ones are the Cortex™-A15, which usually runs at 2.00 GHz, second ones are the Cortex™-A7, running at 1.4 GHz each.

Basically is like this:


[8 total cores]

core[0] 2.00 Ghz
core[1] 2.00 Ghz
core[2] 2.00 Ghz
core[3] 2.00 Ghz
core[4] 1.40 Ghz
core[5] 1.40 Ghz
core[6] 1.40 Ghz
core[7] 1.40 Ghz

Downclocking the first four ones, will save around 1Watt in terms of power usage (per board). And with only  5-6 h/m lost per board.
If thermal throttling kicks in, well you'll have everything forced to be setted more lower, like 1.4Ghz + 1.2Ghz. Maybe it could be more setting a performace mode using cpufrequtils but..I think it's not worth!

Anyway, if someone needs to know how to overclock or downclock those xu4 based boards, here's the code:



Add those lines for 1.9 GHz



And the trick is done :)

Nice Jacko,

Looks like Verium CPU mining is becoming really popular, network hash rate keeps increasing and we keep adding pools to the network.

http://veriumstats.vericoin.info/

Pools

https://pools.bloxstor.com
https://beertendr.com
https://vrm.poolinat0r.com
https://vrm2.poolinat0r.com
https://vrm.poolsloth.com
https://vrm.mining-pool.ovh
https://vrm.poolium.win


Our network consensus is better then most coins like ZEC which is worth 100x what Verium is worth with less development and technology.

https://twitter.com/VeriumReserve/status/911660588698234880

With the new Verium Vault 1.1 days away, looks like things are going to take off!

Seems like a really nice and fun project! Keep us posted, really eager to see the final result! :)

All the best!

I'm curious about result ... good luck  ;)
i help
your hashrate will be 475 H/s = 5 VRM daily = 9$ daily if diff will be still same (i doubt,cos raise) = your ROI= 722 days  ::)  better option is give your € to VTC,VERIUM on marketplace  ;)
all this parameters/values is for free electricity

your rig = 1.2KWh x 24hours = 28.8kW for 1 day= 864kWperMonth

most customers in EU got 0.13€ perKW/h  = 112€ monthly for your rig


 ???

nice thread!  :) looking forward to results

Verium it's maybe the main purpose for this build, but not the unique one! As I've explained so far, this will come handy while doing render jobs for work.
Some of your calculations are wrong, and maybe too much "good". I mean, having everything working will cost almost 280 eur/month in electricity :)
ROI is far away, yes, but I'm not here talking about ROI, money, profitability and so on. (As you can read from the disclaimer).

Anyway, don't worry, every single thing you'll see, every cable, every microSD, was very,very,very well preventivated and calculated

I wanna try keeping this as a "building up" thread as much as I can  :)

600cores=75xu4= 75x16w=1200W=1.2kWh  ;)   your xu4 is any special?  ;D

Holy cow! Once you're done, please let us know how it all went.

Well, those are not XU4, the xu4 is the boards which those are based on.
A user already tested those boards, in terms of power consumption, comparing them into multiple cases, even when downclocked.

This is with 2.0GHz
http://i64.tinypic.com/zvejbd.png

Reference, thanks to JagDoc: https://www.planet3dnow.de/vbulletin/threads/428622-Odroid-HC1


ps: a XU4, on full load, doesn't reach 16Watts. My initial 24, were around 13-14 watts each.

:)

then your 600cores is how much SBCs? classic 75 pieces/8cores?
1 SBC how much hashrate= .ca 380 h/m?

1 SBC 12.2 wphour?  im think about 16 wphour

thx

1SBC is 1 odroid HC-1.
It's xu4 based, so it will do 380 h/m.

I expect 13W/each, no way a single one use 16W  :D

then consumption will be better 75*13W=  91€ monthly for 75pieces=600cores

but ROI is massacer

you need electricity from ENEL  ;D

As I wrote, ROI is not the main point of this thread, but will come. Verium and vrc are two bombs ready to explode. :)
Tomorrow rack and components should be delivered, finger crossed.

600 cores ? am i reading this right?

Yup!

600 cores with a 600 watt PSU is pretty amazing. I'm looking forward to seeing your final rig and results.

I wish I had a machine like you´re building. Good luck!

 75 machines of ODROID HC1   8cores x 75 = 600 cores  :-*
my opinion is better way build 15x Ryzen 1700 .. better for mining CPU coins+sharing STORJ  ;)

Well, buying 15x Ryzen, will cost  around 4100 eur in Italy. Then you should buy motherboards, hard drives, and psu. It will definetly cost more. Also the power draw will almost double :)

Hashrate comparison for almost every CPU be found here --> https://docs.google.com/spreadsheets/d/1O-hyFS-bqsopttmql6NgYWlWej9rZk_lm5MWivnehXg/edit#gid=0

450€ for complete machine in .SK ... your odroid is oldguy.....ryzen 1700 with hdd sharing will be better choice,trust me,i know what talking about

Well I think everyone is free to do whatever he wants, I've decided using SBC's for this project. You could do something similar with Ryzen and create another thread. Could be interesting!

:)

Interesting! I'll be waiting for your result.

jacko!  ;D

i hope you 're doing well ??? please submit your hashrate when you have done.

but i think its better to mine with others things. there is no roi. you have just burnt your vrm wallet  :-*

My vrm wallet?  ???

Edit: seems like the biggest delivery is 1 day delayed. No other pics for today  :-\

Received TONS of eth plugs, cables and accessories for today. Unfortunatly my shipment from Poland will take two days more.  :-\

What is your expected power consumption for 600core machine?

Hi, please note those are rough calculations, we'll see the total power consumption only after I'll plug in the cable!

900-950  watts for SBC and controller
50 watts for the fans
then, add another 50-60 watts for the network switches, PSU dispersion and more..

Should be around 1100 watts at the wall, more probably 1200.

:)

so what profits do you expect from this?

1,3 years for ROI at the moment, you can calc it  :)

Hi,

nice project, keep us  informed and share some nice Pics, really looking forward to see updates! ;)

Finally the first batch, including rack, power supply distribuitor and more is here!
Was a bit tricky without any manual, but yeah, the rack is done!
Now is time to add some nice fuses holders to the psu boards, in order to have a more fast way to replace fuses if they blow up.

 :)

Okay this was literally "the most long day".
To make sure everything works well, I've added 100 fuseholders on the power supply distribuitor, with 100 4A fuses. Replacing fuses will be more easy now.
Fortunatly a friend of mine helped me in this crazy thing! Here's a couple of pictures.

http://i65.tinypic.com/2zjg960.jpg

Now I'm just came back, and found three nice new packages at home! Here you can see tons of MicroSD  ;D

http://i67.tinypic.com/21mhs8g.jpg

Also three 52 port network switches were delivered!

Time to go sleep now !

Interesting topic, I would say it is a good idea to use ARM cpu to mine Verium. Looking forward for your mining rig.

At first i thought this was just another spam topic but wow, impressive build.
1100w for a 600 core build is not bad.

Can you share your profit calculations? How long do you expect ROI?

Will keep checking back for updates on your build. In the meantime i'll look into mining vericoin as well. I feel like i've been living under a rock only finding out about vericoin now.

8 cores with only 2 GB RAM. Good luck mining Verium with that.
Can't find any specs, any SIMD instructions? Cache size?

Already mined more than 4k of vrm with odroids. Atm those sbc are the only way to mine verium without spending tons in electricity. Comparing costs/hashrate, there's nothing else better than those boards.  ;)

with hashrate 475 H/s = 4VRM daily = ROI over 1200 days for 110€ monthly for electricity = premise for constant diff on 0.00925004 : but diff raise

Waiting for more hardware photos. I like projects with monumental approach. And of course Good Luck with the project, will follow

Interesting build!

I like the concept of building a large miner of many smaller energy effecient units. I wonder how the odroid XU4 compares to an Intel Atom X5-Z8350? These small boards are based on Z8350: http://www.up-board.org/upcore/

Alternatively buy many cheap Z83II miniPC on ebay.
But maybe they are not so good at mining, I have not tried.

The problem I see with this build is that IF mining becomes unprofitable, then it becomes a massive task to sell off the parts. I'm assuming the ordoids will be harder to sell than "normal" Intel chips.

What's good for CPU mining is RAM and cache. Most CPU friendly coins can't fullly load a desktop CPU due to memory
and cache limitations. Each Verium thread requires 1 GB. Any SBC with more RAM will do better, 8 cores is overkill.
Idle cores don't use much power but what they do use is wasted.

600cores used just for mining???

am i the only one here thinks of using public equipment or misusing from not very own cores?

1 of my friends told sth like this way before mining got popular, after some time we noticed that he was using his university computers to mine which cost him losing education opportunity


hope you are doing this legally ans in this case wish u success.

also some recommendation, for such electricity consumption, u can really consider green energy solutions ;)

I've sold 25 odroids in 3 days, those are easy to resell ;)


False. Atleast not on ARM architecture. Let me explain.

1 Thread use 128MB of ram. (this is called 1way mining)

If the miner and your processor is capable of some special instruction, you can use 3 way.

1 Thread --> splitted in 3 little worker using 128MB each.

On my I7, it uses 8 cores with (128MB x 3) x 8 -->3072MB

On ARM, you just use 1way and the trick is done:

8 Cores --> 8 Threads --> 1024MB of ram


There's no public equipment, I've buyed all those components on my own :)

http://i63.tinypic.com/15hhd7s.jpg

in this case im very happy for you that you could follow your love and build something like that, wish you success and really consider solar or wind electricity if you live somewhere you have access to free lands.

in such cases, even a small farm can help you decrease bills heavily in a small window time ;)

You're insane, but I'm glad to see that and I admire your hard work. A compatriot that know those things and do the best everytime. Your 600Gb hdd s nothing compared 600 CPU Cores and 150 Gb of RAM

@jacko0088, can you release your mining stat?

im curious if you can kill pools with your hash rates :D

Thank you boys,
no stats to share yet, I'm still waiting for the boards to come.
Also I've just finished creating a configuration file which allows me to share wifi over eth0. (This will go to the main controller).

I've succesfully a stable WiFi connection in my basement (4 meters under terrain).  5Mb/s downlink, 0.5Mb/s uplink.

:)

wooow man you are really something

wish you luck and also success, im gonna use my own PC's for mining too, few 1050ti and 970
, lets see if i can beat you on total hash :D


actually i think you are working better than most of so-called dev o token board with much more better road map ;)

I was a dev too..in the past.. :)

Daamn, that ROI is a SOB, but hopefully the price rises, a lot. :)

This is great project hope to see the result soon. I am a verium miner myself and searching for the one using ODROID

Network plan  :)

http://i63.tinypic.com/2zdncdw.png

Way to go! What I like more here is that you have a side use for all this power, it somehow resembles the beginnings of bitcoin mining

Nice network plan, I'm excited to see your full setup  :)

are you kidding? his hashrate is very poor  ;)

Haha! "render some works"
What are you going to render? The entire world?
Just joking. You have something in mind and the informational thread you've made is awesome. I'd really love to see more from you and your works. Hopefully this whole thing pays out at the end. Good Luck, man!

Well sometimes we have to compute jobs for work, this will come really handy with mpich  :)
Slovakia, yeah, maybe, buy you cannot beat power consumptions advantages with SBCs:)

Impressive, I am following this thread. :)

Wow - sounds interesting and ambitious!

And here I am - planning to use my old Core i3 laptop for mining VRM!  :D :D But in my case I do have free electricity :)

Your project is interesting - it has more ambition than commercial purpose.
Have you written the mining software for ARM by yourself or built it from open-source repositories? Did you try to make ARM-specific optimizations?
Did you try to run other mining algorithms on ARM? Having a mining alternative, if Verium fails commercially, is paramount. I have done a little research about mining on alternative CPU architectures and found that SPARC architecture does not offer any advantage against x86 for most existing algorithms. Glad to hear that at least some algorithm is competitive on ARM.
I consider that your Internet connection is the weak spot - you would better organize a wired connection between the switch and Internet gateway.
Those AC-DC converters you using are LED drivers? I have read that such converters have huge ripple voltage and a server 12VDC PSU would provide much stabler output voltage.

I really love your pictures and install

Thanks for sharing !

PSU just arrived, a bunch of stabilized 5V 30Amps. Each one should keep up 10 sbc :)
Still waiting for the boards.

Any benchmark data of any trial working unit that you have? How much hash power would each core get?

Eager to try as well, awaiting full synchronization with network.

https://i.imgur.com/CBwYNoL.jpg

We normally think about ROI, but it's really not everything.  What's the ROI on a TV, boat, or fishing pole?  None  ;D But they're all fun.  This build is really cool despite that and I'm glad you're having a good time building it!

I am very curious to know hashrate per core too !

This is just a crude test on one of my machine, tested on single core and several more core. Didn't show ideal scaling, but single core give like 300 Hash/m, did not properly optimize for remainder of the core addition test.

Single core test
https://imgur.com/a/e9LXg


More core scaling test
https://imgur.com/a/3euCe

Cool, the verium vault 1.1, recently released, improves the avg hashrate, despite the old one!

Little pro tip: if you have less than 10khs, solo is more profitable in the long run ;9

Hi,

I've been thinking about building something like your project and currently working on a little rig with 14*XU4s in to test things out before going big. I'm in the same situation as you, not very rich, but want to build something to learn and have fun, and maybe even make a profit :)

I noticed you bought the HC-1 machines, and I was just wondering if you've asked Hardkernel about the upcoming MC-1. If you missed this I feel sorry for you since they seem to be exactly what we Odroid-miners want. Or perhaps you have a reason to go with the HC-1s instead?

The info I've found online mentioned MC-1 release in September but it seems like it's been delayed. I haven't contacted Hardkernel about it yet since I still work on my "standard" XU4 cluster. Check this article out:
https://magazine.odroid.com/article/odroid-hc1-and-odroid-mc1/

Yeah, I've asked them directly. MC-1 will not get released soon, everything is delayed and they don't wanna tell us anything. Probably is canceled. HC-1 because of less noise and more stakeable.

Also, HC-1 are moooore easy to resell, who atleast they have a sata plug :)

I had 24 xu4 in the past. Sold in 3 days  :)

Ok, time for update. Sally today got the power!  :)

SBCs were shipped in two batches, no sign of the first one (where the controller is). The stupid USPS tracking is showing "pre-shipping" since 18/10/2017, but I'm sure it's on travel..maybe on a tortoise.. The second batch, sent with UPS, should be here in three days. But I can't do nothing until the first one arrives. Configuring the controller is a pain, and will probably take a whole day. I still have half of the OS to flash on 75 microsd. That will take some more time too.

Power supplies. two switches and the other 60 fans works flawlessly! 110 watts at the wall. Waiting for the boards now

Nice project you got there...been following this. I am a small scale verium miner too and very much excited to see the outcome of this project. Thanks for sharing.

used xeon cpu same cloud vps server?

Not worth the price. Also by further calculations the final power usage should be around 850 watts :)

jacko, you know, i think we are more eager than you to see results :D

this is the only thread that i check daily for your update ;D

i am specially thanking you for making more ppl join the crypto world ;)

Well, thanks!
I'm still flashing the OS images, 75 do to and label. It's not fast. New "real life job" takes me basically all day, so things may'll be more slow. But don't worry, this will be always updated when i can!

nice job cabbage I would like to do with 10 seconds and maybe or too few?
what's wrong with them?
I'm Italian I wrote to you in Italian
Hello

55 boards, just arrived, waiting for the others to start working on it!  ;D

Creative plan  :)
so is there any chance to mining individual ?

Atm, if you are here for the long run, solo mining is still a go. Little miners are paying tons on pool/withdraw fees.

Those are the boards arrived yesterday, first package still missing.

http://i65.tinypic.com/24xkxaa.jpg

Okay boys, it tooks almost three days, but the network bridge is working!

WIFI --> XU4 --> WLAN0 <--> ETH0 -->MINERS

A friend of mine, lent me a normal Odroid XU4 to start with. When the XU4Q comes, I should be able to switch it just by switching the MicroSD (I hope).
Meanwhile I've ordered a 128GB MicroSD in order to have more space on the controller. It should be easy now to set up, especially because I've writted down every single command launched :)

Also both the managed switch are setted up with a static IP. Now I just have to create a custom image to use for HC-1 SBCs.

http://i67.tinypic.com/30m97k8.jpg

Great passion to see a man building his dream even if it wont be productive today who knows what tomorrows bring :-)

For me personally I am not a IT pro but my dreams manifests in a same vain as the work in this thread by the op and ofcourse the legend @birty! I used to mine LTC on GPU's but packed my rigs up years ago now but I ahve returned to CPU mine Verium using hardware I can find in my dusty shelfs, what can be scavenged or salvaged or bought second hand! Right now I have a farm of 37 old intel atom boards up and running and this number will soon double within weeks its just a matter of letting the skin on the end of the fingers heal so that more wiring of power leads and ethernet cables can be performed lol and i have found that I can power 3 micro atx boards from one 250W PSU, granted its sill not odroid effecient but its better than standard PC CPU mining I can run 12 boards of 4 250W psu and the power draw for '12 on 4' is only 160W Max as measured by an inline socket meter from lidl a long time ago lol...
But my proudest achievement in this little project to date is getting veriumMiner complied and working in Tiny Core linux so now the bag of 130Mb USB sticks I found can be used to run the boards cos the system image is a whopping 68Mb it boots in about 15b seconds and mines straight away in screen session:-D

mostly looking forward to the Gemini stage being completed so that VRM >>> VRC conversion can happen locally within wallet and ofcourse the full implementation of the binary blockchain. I think Verium and vericoin are one of cryptos best kept secrets but given the difficulty is on its way to doubling since i started about 7 weeks ago one has to conclude the word is out lol.... Next stop moon..... :-)

I would be interested in seeing videos of this.

What is the ROI on this rig? and how many VRM are you earning ?

Well, today i've found out that the network bridge wasn't working. After hours of trying, switching, rebooting and bla bla bla, I've found the issue!

Both the DLink DES-1210 -58p!
Those are managed switches, this means you've to configure them a bit, even setting a static ip to get them working. The issue? On reboot, they just lose the configuration! so they factory reset everytime I unplug the power.

Seems like the "save button" saves the data just in the RAM. After reboot, everything disappear.

How i've solved it:

- logging in via telnet over port 23
- insert user/pass
- opening the web panel and insert and "save" the configuration
- force a save via telnet (save command)
- reboot.

FIXED

Now everything is ready to host the miners ^^


Cool! ^^



Atm 0, not even started yet!

Just want to chime in with more applause, watching this thread with fellow tinkerer's excitement (I have been toying with weird GPU ideas, like using them as water heaters or installing inside metal casings inside walls, etc, but this mega CPU concept fascinates me to no end)...

How many hash are you expecting from this BEAST of a system? I assume you have done your homework and it won't overwhelm the network (give the network WAY too much hash than it needs- which will SIGNIFICANTLY decrease the ROI of all miners on the network). A coin this small is very easy to overwhelm and could cause some terrible effects to the efficiency of the network until everything stabilizes.

Good luck! :P

OMG it's stunning, please share the results too

Not so much, around 30,000 h/m

Everything arrived! Time to work!  ;D

Make it so!  :D

we should sue þe shipping company for making lots of users waiting for package :D

but good news, we will see some actions sooon,

wish you more hashes jacko ;)

Don't worry, my custom kernel will suck 600 h/m from each board ;) But don't ask me how! :D

Cable time! Now that i've flashed the os on every board, I "just" need to plug in everything. An install.sh script will do the rest!
It will be a looong weekend. Probably I'll not even finish!

http://i67.tinypic.com/wrc2mq.jpg

damn, jacko you are killing us :D

bring the monster online faster so we can see your ROI and profit ;D

Just finished the number 40! Believe me, wiring is a pain.. >:(
I'll try to post a picture tomorrow. Still not mining!

http://i67.tinypic.com/2dqkf2q.png

Today got power issues. Seems like the cables going from the PSU to the input of the power distribuitors were causing a bottleneck, with consequence a voltage drop.
Miners hangs due to undervolting and simply stop working.

The lesson I want to share today is this: if you're mining, with custom things, a multimeter can literally become your best friend  :)
I've fixed one line, so i've not started to mine yet. I'll try to fix the rest by tomorrow, and hope to get everything up and running at sunday. Real life job takes all the time from me  :P

Impressive, can we get along the way the cost for components and the amount of hours spent on your project and what values are you getting ?

Also I'm really interested in the rendering part, If I understood correctly these are ARM SoCs so no X64 X86 right ? so you must be running some linux distro, can CFD or other numerical simulation software run on those ?

Looking forward to the development of this project and the results

WOW, impressive ! I'll follow this thread too

Man, you're a beast ! you should sell some professional rigs like this, you'll become rich :)

Good luck for finishing all this

woow, too much technical points, i feel like i am a kid stuck between 2 professors of university :D
you are not alone buddy, in last few days, i am just coming here to see ho jacko is doing :D

Your equipment is impressive. I think many on this forum would like to have such a set of computer equipment. You have more resources. I wish you success.

Should I quantify? Flashing each one takes 20 mins/each. Wiring? Tons of time. I've spent 5k on materials, but feels like i've spent 10k only in "manual work"  ;D

Yes this is what I'm getting at, sounds, like a lot of work but if it is a hobby you are enjoying and you have the time to allocate, I think it's really worth it even if the ROI is not there this project can have many other use cases other than just mining

"would like to have" ??

I'll die to SEE it in action :D

Well!
I've found out two of the 40 miners were hanging with no reason. I'm reflashing both, hoping to fix the issue. I don't want a broken board now!

So i've added some fan on the right panel. Also because, as everyone knows, RGB gives you 30% more of hashrate  ;D

Considering the frequencies you are running at, the architecture you are using you shouldn't even need those, are there any components specifically overheating ?

I mean the SoC them selfs use a Watt or two at most tree but like you said better safe than sorry also, the cooler they run the better they run and no trottling risk

PSU are warm, and pulling out hot air from a flank, it's a good idea.
Number 75 flashed! Sally will b up and running by tomorrow!  :-*

Oh I thought the PSUs were exhausting outside, now I understand, 75 great news, 525 to go, you are getting faster at it, I think in a couple of weeks we will see a full 600 machines results good job !

Read better! 600 cores, not machines!
Machines are 75! :P

I'm sorry when I commented I wasn't under my dose of caffeine I didn't get enough sleep in the last 72hours, Yes those are 8 cores SoCs so You are basically done, with the installation now is time for some fine tuning to get the best performance out of those core, by the way what OS/distro are you running on them right now

ubuntu minimal, i have just to wire them up tomorrow morning  :)

Alright, really looking up for tomorrow and hopefully we will get some results, also if you don't mind, can you try some CFD software later on or any numerical simulation software you might have ? for the sake of benchmarking

I can simply create a script to calculate the prime numbers from 0 to X, run on a single one, then run in parallel. For a fast test.
Time is running low, not only for this build, but also because in some days i'll not have much time to dedicate. The goal is getting this running "on is own".

 :)

Yes I understand, if you can at least run a linpack benchmark or geekbench if possible, and those mining numbers It would be fun to see how those SoCs campares to your average CPU, I might be inspired by your work and do something similar and smaller scale at first and scale up afterward

It's finished. I'l post a picture tomorrow  ;D

It is very amazing post and updates. Did you cluster all odroid into one? I was wondering clustering should save hassle in management, but wondering if it is possible to mine.

Thank you for the good work, I'm really looking forward for it, and Hopefully not A picture, but pictureS so we can get our nerdgasm


I believe it is possible to mine without any issues, since each SoC is an independent worker and doesn't rely on the other.

when is tomorrow :D

and inform us about the network u will free your beast there, wanna to see hash changes there  ;D

jacko, you are few hours late buddy,

come up, show us your monster ;D

Yeaah

We need photos and datas

Please !

A bit busy! But i'll upload something in the next hours!
I've found out that my psu are not enough, and 5 miners don't receive enough power to mine!
I should buy 8x 5v 40A :(

Great news, well with 70 of them it should be pretty representative ! looking forward for the pictureS and some numbers and results

It's not a good new! Because i have to buy 8 new psu!
Here's a first picture! But i don't like it now! Full pics and details when the new psu will come. I'm basically running everything with seven cores each, can't keep up :(
http://i65.tinypic.com/2w3ri81.jpg

I know but what I meant is that you are basically done, with all the wiring the flashing and everything and you basically need the power supplies to run this baby full throttle.

By the way did you try to rush with the current power supply configuration and downloading all cores to 1Ghz or a little bellow. is it possible, or is it to much work especially if you need to go trough them one SoC at a time 

I have to ssh into each one to downclock properly. I have new psu on the way, it should take another week..

What a bummer, we have to wait another week to see the results of this project, nevertheless the bulk of the work is work is done and I think it will give you the time to work on the software side and optimize the mining software and co

I know, it sucks :(

But meanwhile, i've started this topic too, where you can see sally's final look :)

https://bitcointalk.org/index.php?topic=2485396.0

I don't know anything about this coin, but you sure do! What a really cool looking rack of electronics., Ill have to read this thread again... Good Luck!

Yes, I've checked the thread so far people are posting some awsome builds there, btw, your scrypt^2 mining was it a default choice after doing some benchmarks, or you just arbitrary to choose to mine with that algo ?

Any updates on the project ? we didn't here from you in while, did you get the PSUs? starting mining at full power ? any numbers? please keeps updated, we are looking forward for the numbers

Scheduled delivery on monday  :-[

Well package arrived...but amazon fucked up!
They've sent me some honey tablets by mistake.
Never happened with amazon, now I've placed the order again.

Should I say "I'm getting angry?"  >:(

hey!.. just chanced upon this.

i recently setup my own odroid farm as well... small one... 5 x MC1.. 160 cores .. MC1s avail now btw..
about 7 days in so far... hasn't mined anything while doing solo... am wondering if verium mining favors heavy duty machines that churns bigger hash rates rather than many small ones...

Hmm, you should've hit at least one block in all that time. Lots of us Verium miners use SBC rigs and I've never heard anything about higher h/m machines being more suited for the job. Have you joined the Slack? https://vericoinandverium.slack.com/messages

looking forward to see it up and running

PSU arrived today, testing things up tonight  :)

This is awesome, can't wait to see pictures of everything and see some results.
Bravo sir, bravo.

That is definatly an epic project! Good luck! :)

And...
...have patience! ;)

Ok new psu is OK, solution is buy 10 new PSU. DAMMIT!

..order placed

This is a very interesting project.
It inspired me to also investigate in this area too.
So I have bought the cluster version of the your boards which is available now: Odroid-MC1 (http://www.hardkernel.com/main/products/prdt_info.php?g_code=G150152508314)

This thread inspired me too

I try to mine VRM with a ryzen 1950X.
No block found during almost 7 days mining :(

The author is a real maniac :) I'd really like to see real photos of the finished farm

how do i join?.... it says i need an invite from the owner of the workspace..

yea i hit a few blocks just a few days back... and wow... the network hash rate doubled these few days...

Pretty ambitious. I wonder what speed you can get moving at. If you are not careful the tech and hardware that you start with will be old school to mining before finishing the project. It will be a nice thing to watch. I like the fact that you back down the CPU's, rather than try to push them the other direction, that has a good effect on your longevity. Seems you will get a good bit done before there will even be a glitch or oddity to run down.

It seems pretty dead to me... Since 17th Dec. no update from the OP... Pity..

Just waiting the PSU's and enjoyin vacations..  ;)

ooh jacko you are still waiting for packages x_X
how can you be so patient with shipping companies, if it was me i had been killed few of their staff till now :D

was out for few days, but i am back and will wait for your updates

Does someone know how to setup an Odroid XU4 to mine Verium in a Pool?
thx

it's crazy, looking forword your hashrate.

Clone and compile veriumMiner from github, then launch it. Its linux

Glad you did not abandoned this project! Looking forward to it! Good job!  :)

Hi jacko,

Have you brought your monster online?
I see many hash changes on some altcoins, thiught it may be you ;D

Not yet, delivery at 26th...  ??? >:( >:( >:( >:(

Ooh so you have some silent competitor, will try to find where it was from
And still wish you success on your project

I agree that the Vericoin/Verium combo is very interesting project. Dual blockchain cool concept. Very under-valued.

Me too, I plan to buy MC1 to soon. But my curiousity is jacko0088 mentioned he uses hc1, I noticed that hc1 is cheaper but without display output, then how to configure it? Any resources on net about this issue?

You go blind with linux console over SSH

 :P  :P  Oops... Thx... BTW, how's the performance so far? Any unexpected issue?

@jacko0088, first of all, thanks for inspiration you give to people.

As far as I understand, you are having issues with PSU's, and I think I know the solution.

I was (and I still) playing with SBC clusters and noticed with even powerful PSU may fail, if you will power up e.g. 5 units simultaneously.
The solution was an arduino-like board with some mosfets, which powered devices one-by-one with some delay.
After this power issues are gone and I could utilize some non-atx psu to play with cluster.

May be it can be useful for you.

Uhm..can you explain a bit better?
Now i have a 5V 40Amps powering up 10 SBC--> works flawlessly! I mean, all up and running from a month. Nothing goes down.

So i'm waiting for the 5V 100Amps to be delivered, so i can safely power up 20 SBC's in a row ;)

ATM, all stuck by italian customs.. so I have to wait a bit..

Thanks for sharing info about your cool project.

Imagine a bunch of SBC's connected to one PSU. When you power them all "at once" and each unit starts to do something - mining, whatever - it impacts psu.
Even if psu is powerfull, it may not survive start current for several SBC's simultaineously.
What I have done - I made a simple arduino-based circut, which powers up units not at once, but one-by-one e.g. with 30 seconds delay.
This helps PSU to "survive" start current of devices - load is increased smoothly and PSU works.
I used MeanWell PSU's to power 5 Orange Pi's
Result - one of five devices may not start.
When I added "delayed start" - PSU suffered much less, and everything started to work correctly.

mmh..cool! Will take surely a look  ;D

Okay Sally is slowly booting up. Almost 40 of 75 are working. Had to finish up wiring, but I'm confident for tonight  :P

Great! We all are waiting for the results. But why did you coose this altcoin? Is its mining optimized for this kind of CPU?

Because it's a massive project, and peoples still doesn't know! So there's a HUGE potential.

Binary chain uber alles!  ::)

It's not rentable, but it shows that sally is up and running! Finally! (and it's doing solo mining)

https://www.miningrigrentals.com/rigs/51397

So exciting to see her up and running!

finally, but hashes seems to not in full power mode, is it intentional or not yet optimized?

how much does it make a day ?

Wish you best luck. I like when people thinking out of box.

not yet optimized  :)

Can we get pictures please.

@Jack So I saw Sally is posted for rental on https://www.miningrigrentals.com/rigs/51397/ and was wondering if it was in fact ready for rental for the listed price? If so, I was planning on renting it out for use of some altcoins on N-Scrypt for a few hours. Or does it only mine VeriumReserve?

Actually "it should". And now it's up with my custom miner/kernel dedicated to vrm. So now it mines just vrm.
Price is setted high because i prefer none rent this until i start getting my first solo blocks :P (but yeah, if you rent it at this price for vrm, it switches for vrm)

wish you success there, but if you ever wanted to rent, you can count on me too ;)

Well it's on MRR now  ;D
Can change algo upon request if necessary, but you guys should let me know :P

If you're able to change it for Garlicoin let me know! Would love to rent it for a few hours! Can send a PM if interested! Or if you have discord?

As you wish, i prefer PM

That's it ??
After 10 pages of how you build your supercomputers... nothing more ?
Can you share with us your stats ? your profitability ?
What is your energy consumption ? :).
I know we can rent your supercomputer, but why do you have choose to rent it , why don't you use for yourself 24/7 ?
All the Odroid work great, no troubles ?

Thanks for all these information ! :) But after all your work on it, I think the end is too short... need more info !

 

In fact, I was just to write a message! :D
Well, how is going?

I've had to shut down Sally because of power issues. Again? YES. But now the problem wasn't the PSU, but the cables and the power distribuitors panels on my rack. Those boards were bottlenekking the ability of current to pass trough, causing an huge power dispersion in terms of current and heat.

Solutions was this:
- 4 huge blocks to distribuite the power
- 2 pairs of 20mmq wire in order to attach the psu

Current can flow nicely now. Just had to rewire everything from scratch!

Energy consumption was around 1300 watts. But now that should be rechecked again!
All SBC works always great! (but if the power is not good,they won't! :P )

I've run it stable from 01/02 to 9/02. Got almost 1 block/day.

Atm is on MRR just because i can switch pool/host and monitor stats while I'm away. Rent price is setted high. Just to be sure none will rent it :P

http://i68.tinypic.com/15pibro.png

What board you use to put processor? Any brand? Can you take picture board of cpu. I'm still cannot see how the setup is.

Wow ... just stumbled upon this thread.  Your old posts on Steemit got me into mining Verium.  I only have 6 Odriod, though, expandable to 23, LOL.  Still, it's profitable, just not getting rich.  But they are quiet and are not running up the electric bill.  Your new miner is amazing.  Best of luck to you.

Hola, I'm not birty from steemit, just a friend of him :)

Hey man any update ? Power issues already solved ? I was think about doing something similar but with S912 - 8 core - 2GB

Hi

Some news to share with us ?

Thanks

Doesn't what? Still mining good so far :)

Goodmorning everyone

sorry my bad english google translate from italian.

congratulations for the work you are doing and the passion you are putting

I can not create the image of ubuntu 16XX is constantly restarting someone has suggestions?

I thank those who can help me

If the image isn't corrupt and was burned to the sd card properly, it is most likely one of two things (I encountered both with my odroids):

The sd card isn't fast enough (odroids need Class 10s in my experience, with Sandisk working well for me)

The power cables from your PSU aren't a high enough gauge (write the company you bought them from and find out, they need to be 18AWG or larger)

Have you tried a different image? One of the odroid or mining pre-fab ones perhaps?

Thanks for the reply

I tried with three different power supplies, one even with a modified computer power supply and 5V pickup.

I tried with different images 15. 16. 18. but nothing same problem

the sd was created with notebook and ubuntu operating system

now I try to change the jack cable

I have not been able to use it yet.

the strange thing is that sometimes he left and after a sudo apt update / upgrade started to reboot continuously

Can you test a completely different sd card? It may just be a bad card or a make or class that isn't working.

Also it may very well be the cable. Here are the ones I used that actually worked (went through two other sets before I found them):

https://smile.amazon.com/gp/product/B072BXB2Y8/

Also you may want to check the odroid forums as well, their support personnel actually respond to threads there...

thanks for the collaboration I solved:

I replaced the cable with the connector and it worked without reboot,

actually the cable files were too small.

Thanks again .

now I have another problem with cpuminer.

"scrypt buffer allocation failed"

I solved half of it but I do not like it by halving the threads at -t 4  :-\

Can you drop here the miner starting line? Also make sure you have enough ram available

Hello,

the command line is : ./cpuminer -o stratum+tcp://stratum.beertendr.com:3334 -O Weblogin.WorkerName:WorkerPassword -t 4

if I do not apply the option "-t 4" the following error appears:

"scrypt buffer allocation failed"

So then include it? Good call on beertendr, by the way, they're the only pool I've found that registers my hashrate correctly and pays out accurately. I earn 3x what n3rd3d was paying out on beer.

You will also get a better hashrate if you use fireworm's version of cpuminer in case you aren't already. It can up it as much as 20%.

before starting the miner.

apt-get install htop

htop

make a screenshot and post it here. thanks!

here is the screenshot

http://www.facilehosting.net/screenshot/image1.png

I need to see it before the miner starts...kill cpuminer.

Hello

the strange thing is that with cpuminer-multi all 8 thred work

http://www.facilehosting.net/screenshot/image2.png

mmh..armbian...uhm.. send me a PM with your skype/teamviewer account if you have one
;)

I can not send you PM for the option in your configuration

User 'spiritobiker68' has blocked your personal message.

I can't either  :D

120 VRM/month. Way more if diff decrease.

Hello

'jacko0088' I made a bit of mess with the settings, try now to send PM, even your configuration does not allow you to receive PM from newbies

Roger

Solved  ;)

@jacko0088

Long time lurker here on the fourms....

I gotta say bravo for this setup.

I am very interested in how you are managing this.

Are you using any kind of automation software (ansible chef puppet etc?).

Also one of the things that interested me in the Odroids is the ability to PXE boot them. Im a little surprised you hadn't done this, perhaps the HC1's dont support this?

How have you managed bad cards / bad boards?
 
Thanks,
Twisted

Atm I'use pssh and pscp for manage and send all the configurations scripts. But I've also a software able to do that.

Because I've really never looked into it tbh. And also because the PXE boot on those boards was introduced by hardkernel when i've actually finished buying/flashing/installing all the MicroSD.
 
I don't know, never got a bad one!

Hello guys,
heartbreaking "news".
Sadly neighbours got pissed about the noise: I have 4 weeks to dismantle everything  :'(

Seems like my mining journey has come to an end.
Accepting offers for the whole build (or all the machines), send PM's if interested.
I've just checked out also some other algos, seems like IRIDIUM Coin is ATM more profitable than VRM  :)
(Sally is still mining VRM right now, this rate at 4.8 VRM/DAY. So I'll still leave it mining until I possibily can.)

wow that sucks , is it really that loud? Is there nothing you can do?
p.s do u ship to usa,

I don't know what else I can do, surely the metal walls of my garage are not helping reducing the nois, but it's less noisy than an antminer s9.
I live in an apartment where garages entries are shared with 20 other peoples, if during one condominium meeting even one of these people says no, I have to remove everything.

And that's what happened, two peoples said they dont' want it. And my garage is my garage, is private area. This literally sucks, especially if I think about how much time i've invested in this.  >:(

you could buy soundproofing from amazon maybe? Im lucky my mining operation has not been shut down by my neighbors as well those exhaust fans are really loud

If it was just for the sound...new apartments rules now says none can have electric equipment running in the basement or a non controlled area. You know, fire and bla bla..Sally is filled up with fuses and check, there's no way, it can't burn. :(

ahh , your only option then is to sell or move then

Unfortunatly that's not an option  :D

Selling thread here --> https://bitcointalk.org/index.php?topic=4500313.0

Good project! 1.9 GHz. - strange choice. 600 cores how cool it is! Yes, and the power supply is only 600 watts. Bravo!!
