Making Ethereum or Zcash mining rig

[jenifive]

Hello! Im starting making a couple of rigs for mining ethereum and zcash and another hashimoto currencies.

Is there a problem when you making a rig with 5-6 GPUs on motherboard or not?
I heard that without a problem you can set up 4 GPUs on board. And after 5 GPUs or more there could issues awating for me to optimise system to make it working. Is this right?

So the question is what will be better and more stable.
1. 1 RIG with 4 GPUs on board
2. 1 RIG with 5 or more GPUs.

Or it does not matter they are working the same way okay without any distinctive issues.

If you have a motherboard that supports 6 GPUs and those GPUs are having the same exact characteristics and they are from the same vendor you will be fine

Great! Thank you!

Is there any differnce between choosing 1150, 1151, 1155 sockets?

[evakka]

for the mining purposes it doesn't matter at all

For the combination, mobo that supports 6xGPUs plus the CPU try to find the cheapest in the market

I strongly disagree if you are building only one  1 six card rig

I disagree if you are building only 1 or 2 six card rigs.

At 3 six card rigs I agree somewhat
At 4 or more six card rigs I fully agree.

Is there any differnce between choosing 1150, 1151, 1155 sockets?

all good questions.

let me ask a question or 2 from you.

do you plan on making 1 six rig?

do you plan on expanding to a lot of rigs?

there are downsides to 1 six card rig.  if the psu dies you are doing zero hashing

If you want to hedge and mine both zec and eth  you will not be able to do it simultaneously .

if you have only one rig with six cards trouble shooting it means all your gear is not hashing

I say go with newest mobo  the one below   will do four cards and is a new socket 1151

if you look you will see how I compare it with a six card newer 1151 mobo
what happens is as you scale  past 12 cards  the six card mobo makes sense.

but up to 12 cards the argument for using smaller four card setups is right there.

Below comes from a different post of mine :



this is the cheapest quality small mobo I know

you can start with 2 cards in the slots

and later add  more cards with risers

it can do 2 in slots = 3
it can do 2 in slots and 1 in a riser = 3 card

it can do 1 in one slot and then 3 with risers = 4 card

it is a great trouble shoot board

and it is a gigabyte 250m  so it is physically very small
 80 bucks

I put this cpu in it

http://www.ebay.com/itm/Intel-Core-i3-6100T-3-2GHz-3M-Cache-DualCore-LGA1151-CPU-Processor-SR2HE-/322490605689?

paid 91 for the cpu  it will take this one


http://www.ebay.com/itm/Intel-G4400T-Processor-2-9GHZ-Low-Voltage-CPU-Only-Socket-LGA-1151-NEW-/252844237292?

nice psu sale  so 109
http://www.ebay.com/itm/EVGA-SuperNOVA-220-P2-0750-RX-750W-ATX12V-EPS12V-SLI-Ready-CrossFire-Ready-80-/382026031239?

a stick of ram 25 bucks

http://www.ebay.com/itm/Kingston-16-GB-M-2-NGFF-mSATA-SSD-Chromebooks-Acer-/201888633168?

5 dollars for the m2 and smOS is free at the moment

so 80 mobo
    55 cpu
   109 psu plat evga 750 watt
     25 ram
       5 ssd/os

so 274  for 2 card
    284 for  3 card
    304 for  4 card  you need 3 risers.  

now do this with a six rig
85 but out of stock
https://www.newegg.com/Product/Product.aspx?Item=N82E16813138449


85 mobo
55 cpu
25 ram
5 ssd os
229 for an evga 1200 watt p2 or
189 for an evga  1300 watt g2
 60 for siz risers

so 394 for six cards x 2 = 12 cards at 788 with gold
or  304 for 4 cards x 3 = 12 cards at  912 with plat


so even with 2 six card rigs vs 3 four card rigs   the edge just tips to six card maybe not as the six card may run louder and hotter then the 3 four card setups.

you will save watts with the 3  four card card setups.

All goes by the wayside as you expand   but up to 12 cards it is very close

let me ask a question or 2 from you.

do you plan on making 1 six rig?

do you plan on expanding to a lot of rigs?

Im planning to buy 12-14 GPUs (470s or 480s) and gear for that. (mother, ram, hdd and etc.)
So im looking for an answer of what is better. More motherboard or less motherboards or it does not matter.

If you want to hedge and mine both zec and eth  you will not be able to do it simultaneously .

No im planning to mine what is profitable to mine at this moment. Not simultaneously.

Sorry to read that  good luck with the coin you pick.

if you are a kind of computer person , and know a few things about pc , and you know how/what you doing then go for a 6-7 cards setup . I never has a problem with none of my rigs , my builds mostly are 7 cards setup ...

if you are a NOB to build computers, and have no idea about fine tuning your bios , your cards, your rigs then go for a 4-5 cards setup .
YES , you can read a lot of posts here , like omg windows can not see my 6th or 7th cards . Those ppl dont have a basic knowledge how to build computers.

Make sure you know your future system total power draw at the wall , not from gpuz ... make sure you get the right psu for your setup , make sure you get powered risers ,then you should be ok

Dont be cheap on your psu , get a brand name with 10 years warranty

Cpu socket really doesn't matter

If you have a motherboard that supports 6 GPUs and those GPUs are having the same exact characteristics and they are from the same vendor you will be fine

really doesnt' matter , but much easier to fine tune the cards if they are the same model from the same manufacturer

Im planning to buy 12-14 GPUs (470s or 480s) and gear for that. (mother, ram, hdd and etc.)

i would go for a less mobo more cards setups

and... you can mine zec and eth simultaneously on the 6 cards setup :)or any setup with more than 1 cards

So for now im planning to mine either Ethereum os zcash until its avaliable to mine.
After than i will be mining something else.
Thanks!

Why would you need a good i3 instead of intel Pentrium or Celeron?

nice psu sale  so 109

Is it enough such small watt PSU for 4 GPUs? (470 or 480)

and... you can mine zec and eth simultaneously on the 6 cards setup :)or any setup with more than 1 cards

How could you mine zec and eth simultaneously?

[xxcsu]

and... you can mine zec and eth simultaneously on the 6 cards setup :)or any setup with more than 1 cards

How could you mine zec and eth simultaneously?

very simple ... 1 card for zec and 1 card for eth or 2 card for zec and 1 for eth ...

[jenifive]

How could you mine zec and eth simultaneously?

very simple ... 1 card for zec and 1 card for eth or 2 card for zec and 1 for eth ...

But what is the point?  You either choose to mine ether or zec. Or is there some kind of reason?

[jenifive]

Am i understand this right that the best GPU choise for mining ethereum right now is
Sapphire Nitro OC Radeon RX 470 1140Mhz PCI-E 3.0 8192Mb 8000Mhz?

Its cheaper than 480, making 20% less power consumption, and almost the same hashreate as 480 (3-4 MHS).


Also what is the better choice:


Sapphire Nitro OC Radeon RX 470 1140Mhz PCI-E 3.0 8192Mb 8000Mhz

or


MSI Radeon RX 470 1254Mhz PCI-E 3.0 8192Mb 6700Mhz

THE POINT IS ... SOMEONE TOLD YOU ITS NOT POSSIBLE , THAT IS NOT TRUE
THE POINT IS ... YOU ASKED A QUESTION , AND YOU GOT A ANSWER

That extra 3-4 MH/s /cards with a 6 cards setup is generating for you a extra 24MH/s hash rate , with today difficulty and usd/eth price is around 55$ extra  for you / months , or 673USD / year

TPD on 470 is 120 watt
TPD on 480 is 150 watt

Thats + 20% to electrivity cost


2-3 mhs is around 11-12% to profit gaining.

So its reasonable to buy 470 8gb

The TDP is not the actual power usage.

Oh i didnt know that.

How can i compare power watt consumption on 470 and 480?

What is the best 470, 480 GPU manufacturer to buy?
MSI, Sapphire, XFX?

What is the best 470, 480 GPU manufacturer to buy?
MSI, Sapphire, XFX?

Msi gamer red led = good I owned 50 of them rx 470 8gb, rx 470 4gb, rx 480 8gb, rx 480 4gb all four models  purchased them since last august .  0 failed in my usage I sold off 48 of them the last 2 months  1 failed in someone else's hands.

so 49 of 50 still work  they look good with all the leds and they are quiet. I was able to do an rma for the dead one.

sapphire = some good some bad. 2 failed  I had 6 or 8 of them  the failures happened after I sold them. I was not able to do an rma it was denied

xfx = some good some bad  I had about 10 sold them all none have died.

asus strix 480 8gb = good  I still have 4 of these.  I had as many as 7 of them.  1 died it shorted It may have been my error
i got an rma for it.

to me if I was still buying rx 470's or 480's  I would want the best price on 8gb models  I would no longer buy any 4gb models

unless the price was stupid cheap like ½ of an 8gb model.
