"AmazonGlobal Shipping   +   $17.77"

I know Amazon gets it's shipping for real cheap (some claim below cost) but just as an example of more expected shipping cost on an item like this.

I've been having reoccurring
on Ethash for some weeks now and i use a epools.txt (Claymore 11. with the contents:
Swapping adress makes the connection work for some time and sometimes it starts to work after a minute or two.

I have another rig on the same router (so same DNS etc) using europe.equihash-hub.miningpoolhub.com:20595 (BitCoin-Gold) which have no issues whatsoever, so I do not think it's my side that is at main fault.

The Etherium dashboard says it hold >10% of the net hashrate so there might just be a overload of the server accepting requests (so it actually is closing the socket).

My ping time to the europe.ethash-hub.miningpoolhub.com is about 60ms (not bad for shared 3G)
when I get connection to asia.ethash-hub.miningpoolhub.com its about 350ms
and just for fun I'm not able to ping us-east.ethash-hub.miningpoolhub.com now.

Am I on the right track here, that the servers are struggling with handling the Etherium traffic and I just need to scare others away to other pools to get more MPH power for myself?
I'm unsure if a faster network on my side would help that much here (the optofiber will not be installed until next month), faster clients usually give servers more headache (at least at work).

It will stay in the custom clearance area (in the destination country), but that's pretty far from the Mineority farm, and reasonably close in time to the goods being shipped, not 1-3 years before.

And if the value of the thing have dropped (old, being used etc) the Import charges and VAT will be lower of course (shipping used cars in containers is commonplace).

So why pay EU VAT on "machinery" that stays in the US? If I invest in stock on Nasdaq I don't pay any EU VAT.

Hosting the card can be seen as a service, and I don't think that there are (EU) VAT on services you place in the "third world". I have never paid VAT on e.g. web hosting services (but that is not proof that I shouldn't).

VAT on imported goods is due after delivery to the full value (including shipping and whatever import charges there will be in these trade war times). Tax on earnings is also not due until they arrive into EU.

I don't have a clue about B2B taxes for cards shipped to Mineorety, but being US it should be a lot less than 20% (or I've got the wrong idea).

Buy a used rig with some small cards (1050ti, 560s etc) to get some experience without blowing to much cash.
You will not earn noticeable coins but you will get experience.
If you think it will be more fun with bigger cards, sell the small ones.
A 6x1050ti rig should be (a lot) less than $1k.

Staying on the 1060 track (9 of them in my rig, on risers of course), would a CLE-215 only make one 1060 double it's hashrate, selling 1.5 1060 to afford the CLE-215 sound like a daft deal.

But if a CLE-215 + 3x 1060 (in the mobo slots) would hash like 5x 1060 it starts to make some sense (complete guesswork). But for me that would mean build two new rigs and 3x CLE-215 to reach 15x 1060 hashrate.
Adding a 6x1060 rig to my current would be about the same cost (using $300 as a low end for an empty rig).

But if a CLE-215 could add some meaning on a 9x1060 rig with all GPUs on rises it would be an interesting experience, but so far I think that is a no-no due to poor bandwidth to the GPUs, the cheepo CPU is probably also a limitation.

In for decent examples of rig setups for the Acorns

Personally i don't care about the power efficiency since I can make use of the puny power (about 1KW) to heat my basement and thereby add to the house heating 8 months on the year.

It will be interesting how this will make me split up my puny 9x1060 rig. 3 rigs with 3 cards (directly on MB) + acorn each I guess, since risers does not give enough bandwidth.
"the SQRL Dual M.2 + USB-Based PCIe Riser Host Board (Coming Soon)" sounds interesting?

The classic 12GPU rig build appears to be different with the Acorn in the mix.

Focused inlet with filters make an over-pressure in the whole building, and all the outlets can be whatever gaps etc.
Reverse things and you will have unfiltered (dusty) air seeping in everywhere, not very nice in the spring with all the pollen in the air.

It looks a lot tidier as well with the cabinet closed 

Are your rigs oriented with the backplates of the cards pointing up?
Any pictures of the cabinet open?

It's all about airflow past the cards.
Not mine at all, but good summary of a lot of thoughts around cooling open air rigs with "hot" air.

Notice the comments about the improvements made related to the airflow past the cards.

My own rig is spaced up to have 8cm c-c between the cards and a 12 inch table fan circulating the air through the basement. It's only a 9 card 1KW rig and the cards are running below 60 C. The next experiment would be to baffle airflow past the cards using 4x140mm chassi fans (one sheet at riser level and one at the top of the cards), but it works so well already, getting the cards down to 50C will not gain much since the OC ability does not seem to be that affected by temp when they are this low.

The fan circulating the air dropped the card temps about 10C, so general ventilation is very important, as it also helps getting the heat out to the surroundings (It distributes the hot air in the air volume, improves transfer of heat to walls etc) even if you don't exhaust the air.

Remember that exhausting air menas it must leak in somewhere else, and doors suddenly slamming shut can be annoying to someone important in the family...

Apparently by raising to 120W...  



Typo I guess, it makes sense if it should be 1070 at 120W with 30.5 MH

I get 23.5 in average my 9x1060 with micron at 75W, so 1060 with Samsung would score high in the MH/W scale every day.

But 1080ti will have a decent resale value for longer (but 3x cost for 2x hashrate and close to 3x power??)...

Shutting (power) down or rebooting?

Since you have -r 1 for claymore, what's in the terminal before claymore runs the reboot script (connecting with SSH is convenient way to have a small trackrecord of the last entries on the screen)?

Have you tried adding the risers+cards one by one (my suspicion is that one riser or one card is to blame)?

Is this still max 13 video cards and the other 7 miner cards (with no video out) due to 16 Hi IO (PCI) lanes from CPU?

It appears so since the link tested with 12+8 (Video+Miner).

1. Because not windows
2. about 250 hours between restarts due to GPU being lost with SMOS on 4GB RAM (2GB free, no swap use at all, 32GB SSD)

This with Claymore 11.7 on SMOS using 9x 1060 3GB Micron

After changing to cheap 32GB SSD's stability over time improved a lot. No need to use USB sticks.
You just need to choose advanced mode in etcher to burn to SSD/HDs.

Hmm, you all make my Asus 1060 OC3G with micron (I suspect) memory which I payed less than €3K for (at the highest boom) as a steal.
9 of them average at 210MH/s ethash (claymore on simplemining.net, and memory dialed back a little from max, never tested plain values).
3GB is enough on Linux for etherium until it goes PoS, then do something else.
How I managed to get 10 (one died after a month)  with the same memory form 5 different suppliers is a mystery.

Interesting note about DC to AC conversion loss in relation to mining...
What Mining equipment uses AC?
Stack up on 12V batteries and feed them with the solar panels (yes, batteries are not free or risk free etc...).

But it's all about scale. If you can buy the Hoover dam and use all of that power to mining, it's a little bigger than a 2Kw 12 GPU miner that can be driven by 4 persons on exercise bikes (pedaling like crazy).

A normal residential Solar roof have about 30 year lifetime and a 10 year ROI here in Scandinavia.
In a high tax situation you don't pay tax on self-generated power.
In the summer we have surplus die to 18-20 sunhours per day, so we can use some to drive more cooling fans
In the winter we need some of the heat so the bought in power is not that costly (and the solar give some as long as you remove the snow from the panels).

There are two different typs in that image, both cheap. The one to the right is a card with 4 "usb" connections to 4 single risers, about $15-20 plus the cost of the risers.
The one on the left is a one "usb" to a card with 4 slots (and requires 5+12V on Molex no 3), costs $20-25, I have not had good luck with this type.

High pressure fans and controlled airflow (i.e the case) is the way to get control of things. Not as cheap up front as getting a bigger and bigger pile of sub-par stuff after constant upgrades.
But it is a journey up the ladder of experience. In the end, some convenience is worth the investment.

Then burn the image on an ancient little 2.5" mechanical SATA disk to get around the problem?
