600 cores ? am i reading this right?

75 machines of ODROID HC1 8cores x 75 = 600 cores Kiss

my opinion is better way build 15x Ryzen 1700 .. better for mining CPU coins+sharing STORJ Wink

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

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

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

but ROI is massacer

you need electricity from ENEL Grin

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.

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 Cheesy

600cores=75xu4= 75x16w=1200W=1.2kWh Wink

your xu4 is any special? Grin

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

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.

I'm curious about result ... good luck Wink

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 Roll Eyes

better option is give your € to VTC,VERIUM on marketplace Wink

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

Huh

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

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.

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

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:

Code:

apt-get install cpufrequtils
cd /etc/default/
touch cpufrequtils
nano cpufrequtils

Add those lines for 1.9 GHz

Quote

ENABLE="true"
GOVERNOR="performance"
MAX_SPEED=1900000
MIN_SPEED=1900000

And the trick is done
