8 cards is a major speedbump in multiple GPU systems.   Usually requires driver/bios mods.


They are giving good info.   I suggest you read others' threads on multiple GPU systems.   Theres LOTS of good info and things to learn just by going through what they did first.

Also,
They also make connectors that link the motherboard power cables so they power on at the same time.   Its smart to have identical power supplies so they turn on at the same time or problems arise.

Yeah, one of the things I hate about new product purchasing.

I will admit; the small thin form factor is going to allow a LOT of people to upgrade to a beefy gpu for once, and I think that's a huge reason why they are going to be popular...

glad it got you sorted out.

If anything major happens, don't hesitate to ask here or send me a pm.. but most answers are in those links =)

For profitability calculating:
Since you are running a mixed density rig, you just gotta go for the overall rig hashrate and multiply it against the 24hr average for that algo... and you will get a rouch idea +-20% (as the profitability fluctuates and the accuracy decreases in turn)

For pool auto-switching profitability, we call it normalization and its in the links above.  Id suggest use normalization for the 1060/1070 with the values my batch has in the password field;  should be fine.

As for the RX480;  I have yet to buy ant ATI cards for mining, so I do not know what app/versions are best for each algo, so more searching or some other members here will help... but AFAIK, eth is still one of the most profitable for ATI, they are more suited to that type of task.  The nvidia cards really scream on the different algos once the miner app is optimized to the chip generations features.

FYI, I am unsure if its in my sig link (batch) post, but for the nvidia 10 series cards, I suggest trying ccmineralexis78 first.  Minerx117 compiled it, and you can download just that .exe from his mega link if you do not have the ability to compile the github source yourself: By clicking here.

get a wallet for the algorythm you want to mine.   Set it up, update the blockchain, then connect to the wallet and mine like any other coin.

There are lots of how-to's on starting mining a single coin.

Yeah, I am in the Bay area cali... quite a swing of issues to deal with each season...  Especially being in the cuts like I am.  Indoors sometimes it seems like it probably is dustier in my house than it is in phillip's shed... lol

Did you mean CNNC?

Ill say this;  the 1070, and 1080 make a killing mining skein...

http://zpool.ca/?address=1kLsGT9egk3utSKZH46ydTbKj5oMnmBoN 6x1080, 1x1070 and 6x1080 (i think 6x is the last count);  idk if he returned one or not.

Also look into using something like zpool.ca for a pool.  I have been using them since they started the site in beta.

if you get a gtx 1060... you would make some decent returns on the skein algo.... I've been doing quite well with it in the past few months, and even more with the optimized ccminer alexis78 build.  The nvidia cards have better resale value, and are proving to be more efficient in many ways.  My 3x 1070 equivalent test farm turns out 0.420BTC+ every 2 months mining only skein (based on last 2 months).

With zpool it's as simple as using a BTC address as your username, and your password is just to tell it what your payout coin is (c=BTC is the shortest password I suggest).  Just download the miner app, connect to the address/port, and wait for returns.

I have written profit switching and manual switching batch files for zpool.  Also have many tutorials and info for getting started via the batch link in my sig.

for the avalon and antminer style miners, I highly suggest heat/insulated ducting for the exhaust portion.

Not only does it reduce the whine/howl, but it allows you to precisely control the airflow from it.  I just used the aluminum air duct tape to seal it to the end of the miner's fan.  It worked like a champ.   Not only that, but if you got an air filter for a big diesel engine;  you could have an easy to clean/change filter on the air inlet as well.

The ducting cost was worth the investment in my opinion.  I was able to route the exhaust to an outdoor vent directly, and run an antminer in a closed space smaller than a closet without temp problems.

With 400W, put one GTX1080 in a microATX board and have it mine altcoins on a pool that auto-exchanges for bitcoin.  Easy peasey.  It will earn much much more than any SHA or scrypt asic.... WAAAAAY more.  And be UNDER the 400W allotment.....

IMHO, power is lower on the list because everything should be designed with a 20% tolerance for reliability/safety... if you have to go over that, upgrade...

And lastly;  the biggest for a lot;  dev's abandoning coins, or market prices tanking.  Those are heartbreakers for some.

Go with the rosewell if you buy a premade rack, or are handy with some metal scraps, a hacksaw and a rivet gun....  Only basic tools/skills needed.

In my eyes its extremely optimal.  You can route air from the front to the back (or vice versa) which makes airflow across the cards very controllable; and feeding a filtered air source, or funneling hot air out to a ventilation point....  Most open racks and such are efficient;  but they get dirty; and quickly depending on circumstances.

I literally took a slide in mesh screen from an old pc case, and pushed it flat up against the fans in front.  Mainly to catch the large dust and debris that causes the biggest and fastest airflow problems.

There is tons of room in this case for the larger GPU's....   You can easily fit the EVGA GTX 1080/70 ACX3.0 style ones in there;  they are the cards that are super large, overbuilt power phases, etc.  I love the case.  Its robust, plenty of room, good mounting room, you could even fit a second PSU if you wanted to squeeze.

The upgraded fans are a must with over 2x GPU;  you need to move the air through the system to get enough convection cooling plain and simple.  They are in an enclosed space.  The OEM fans are low speed and don't move enough air for that amount of heat.  2X gpu stresses the capability of the original cooling fans.  A 960 SSC and a 980 to be exact;  I wouldn't put another GPU without swapping out the fans.

Its nice having a self contained unit.  I just have the back of it pointed towards the outward air, and the inlet towards the fresh air source.   My personal one is in a room that has a thermostatically controlled ceiling fan to keep temps in the room down, so that's one scenario anyways.

Better airflow through the miner makes a hashrate difference of 8-10%.  No joke.  Once I swapped for a free flowing mesh screen, in the same exact position/conditions, I get higher hashrates.    All cards on stock settings mind you.  Trying to keep it as static of a test as possible.   I bet if I upgraded the fans, it would be fine with the old filter and grill... but it would clog VERY quickly and heat right back up.

deep learning computing is basically the same at mining;  only the deep learning the algorithms change.

Their features are prime for mining if you ask me.

biggest problems for people with working miners:

Heat

Dust

Power


That's pretty much the stint of it.  Any other issues are related to quality of hardware, or how hard you run the cards and if you wnt to do anything past stock card settings.

These are the reasons you should read phil's threads... they are a goldmine... they will answer much more than just this =)

FWIW I have used ribbon risers before.

As long as they have their own power cable to power them, id say they are useable.

They aren't for systems that will see lots of movement or be taken apart a lot....  They are very fragile compared to the typical powered risers.

Volta is gonna kill the GPU mining scene.... this is intense.  I know what upgrade I am gonna save for =)

Hopefully they are smart with this GPU and are gonna leave the 1080Ti in its hotspot for a while.... since its gonna handle most gamers happy for a long while.

The price is what concerns me...

Then again;  the drop on all the pascal card prices will be interesting as well;  the fight will be between hashrate density and rig count.

I wonder how much more efficient they are getting at that point;  W/Mh percentage.....   like 20%?  or more realistically 5-10%?

you are going to have to read people's threads.   The Altcoin thread has links to all the previous ones... which give a history so you can look at what the future is looking like.

There are also several recent threads here from the past few days explaining the price and profitability of the new 47080 or 570/80 cards.

I have been using these.

They require making a framework/brackets to support the GPU's, and the front facing fans that originally mount to the bracketry you remove.  Other than that they are awesome cases.


You could also take the mid-bar of fans and put them at the front in the open hole to replace the specially mounted front ones;  We did it in one machine.  Works great.

But;  Replace all the fans with >120CFM fans.    Trust me.  It needs the airflow with more than 2 GPU.

Also;  if you are in a dusty environment;  remove the OEM front cover's filter and plastic housing.  Run filtration elsewhere, or at least something that flows better.

Im liking that board better personally.  Most of the time, if you go over 3-4 GPU, you'll want risers and better spacing anyways.

If I buy a newer generation board, I may go after that one....
