[pictures of my rig:]

I still got 3 rigs laying around with 28x rx580+ 8gb cards and don’t know what to do to be honest. Where would you place the value of this system? As I see it I got basically 3 options

options:
1. sell the miner right now dirt cheap and hope to find some enthusiast (but who would by a miner now?!)
2. try to sell each gpu / psu solely (would work but lot of effort
3. wait and hope in a couple of months prices are better in order to sell my miners

As I see it currently with the market, development, pos on the horizon etc. it will just getting worse. Hardware will just lose more value and hashrates gonna continue raising so I need to act now. Would favor a solution to sell all at once but would take a huge loss anyway. My PSU I could sell probably with a moderate loss, rx580 is overfloating the market. In my country (Switzerland) new card is retailed around 220 dollars, second hand you get them between 120 - 180.

Rig 01:
Board:  ASRock 110 Pro BTC+
CPU: Intel Celeron G3900, 2,8 GHz (Skylake) Sockel 1151 - boxed
RAM: 1x Crucial Value Series DDR4-2133, CL15 - 4 GB
PSU: 2x EVGA Supernova 750G2
GPU: 8x Sapphire RX580 NITRO+ SE (8GB, High End)
SSD: Western Digital WD Green (120GB, 2.5")

Rig 02:
Board:  ASRock 110 Pro BTC+
CPU: Intel Celeron G3900, 2,8 GHz (Skylake) Sockel 1151 - boxed
RAM: 2x Crucial Value Series DDR4-2133, CL15 - 4 GB (total 8gb)
PSU: 1x Corsair HX1200i + 2x Corsair HX750i
GPU: 7x Sapphire RX580 NITRO+ (8GB, High End)
SSD: Western Digital WD Green (120GB, 2.5")

Rig 03:
Board: Asus B250 Mining Edition
CPU: Intel Celeron G3900, 2,8 GHz (Skylake) Sockel 1151 - boxed
RAM: 2x Crucial Value Series DDR4-2133, CL15 - 4 GB (total 8gb)
PSU: 1x Corsair HX1200i + 2x Corsair HX750i
GPU: 13x Sapphire RX580 NITRO+ (8GB, High End)
SSD: Kingston A400 (120GB, 2.5")

/edit: what would be the price for the whole system? 4000 dollars? Well probably not even find someone who would pay so much to make it back I would pay only around 2500 hahahah. By the way stats: around 860 mh/s / 3850 watt.

Hi

I'm keen to know how you control your fans. I would like to optimize my airflow setup and therefore install a 6x fan row. They are all molex powered (some cheap china fans I guess) and chain linked to a single molex adapter. Sure I could connect it directly to my PSU but then I got 100% (too noisy, not efficient). I could use Speedfan tool but therefore I have to connect it directly to my board. Nothing happening when I do that and is it even possible regarding watt if I connect 2 rows à 6 fans (12 total) directly? How do you manage the fan speed of your rig fans? Or should I just buy an external fan adapter like this: https://goo.gl/DoKM67  and connect with an adapter my 2 fan rows? Maybe also switch the fans to those: https://goo.gl/wFZxpu

Hi

I'm currently running rx580 cards and would like to expand with a few nvidia cards. 1080ti is too expensive for me since I would like to add around 6 gpus. For RX cards it's an easy choice (sapphire nitro+) however I don't know which brand I should use for the nividia part? I can get my hands around those cards in my local store in a couple of weeks. Still expensive, but I don't believe we see any decent price drop in the next couple of months.

Power and efficiency is not a primary target (6,5 cents / kwh) it's rather a question which card does represent the best value for money regarding price and hashrate? Did read MSI taking a lot of power and also the Armor cooling (same model used by 1060)is not as good.. 1070ti also doesn't really outperform an 1070, but I think the Asus 1070ti would still be a good choice or better save some bugs and go with the msi 1070? Keen to read your opinion.

Hi Guys

Searched already this forum and also through the internet but it seems there are a lot of different opinions on this topic. I'm building my first mining rig with 6x Sapphire Nitro+ rx580 cards (I'll add more cards in the future but for now I'm running with 6. ) and got an issue with cable connection. I intended to connect 1 gpu and 1 riser with the same power cable, however it's not possible with the cable length (see attached img). So what is the best way to do it? Thought best way to do it is one cable per riser / gpu. I can connect those 6 cards with 6 cables (I only use the 8pin, not 6pin) but how to connect the risers? Should I buy more cables and then power 2x riser per cable separately? Or use a 6pin extension cable like this: /GY1Rpe]https://[Suspicious link removed]/GY1Rpe? Read a lot of different setups but anyway I'll have to buy more cables I guess since adapters shouldn't be used?.




And how to handle it when I'll run even more cards (switching corsair hx750 to 1200w then)?

Thanks for your advice

Hi there

It's just a theoretical question since I don't have the money to do it ;-) However if you would built bigger mining rigs (let's say 30 - 60 cards), is it better to run small systems with 6-8 cards (Asus Prime z270, MSI Z170A, Gigabyte GA-H110 etc) or 13 gpu systems with a ASrock H110 Pro / Asus B250? You're a probably more flexible with smaller rigs regarding cards and psu but need more time to maintain the system. So what would be overall better would you say?

Ciao Zusammen

Habe mich ein wenig durch das Forum gekämpft, bin ein wenig überfordert und wäre dankbar über eure Meinung.

Kurz zu mir: Sind eine kleine 2-Mann Webagentur und möchten primär aus Spass / Neugier einen kleinen Miningrig bauen, einfach um auch mal sich mit der Technologie etc. zu beschäftigen. Profit steht nicht an erster Stelle. Budget ist "offen" (3000 - 5000 Euro, je nach dem was Sinn macht) aber durch die Hardwarelimitierungen in den Shops ist wohl sowieso alles stark eingeschränkt. Effizienz steht aber auch nicht an erster Stelle (bsp. rx580 vs 570), da der Niederstromtarif bei 6 Cents und der Hochstromtarif 10 Cents liegt (Schweiz). Soweit ich es verstanden habe, macht es für uns als Noobs Windows mehr Sinn als Linux (einfacher für dummies, auch bezüglich undervoltage, Wartung etc.) und mit AMD Karten flexibel. Ziel ist es auch nicht BTC, ETH etc. zu minen, sondern eher unbekanntere Coins.

Was haltet ihr von dieser Kombi (bin auch nach Verfügbarkeit gegangen, deshalb fallen Boards wie Asrock 110 BTC leider weg). Gehäuse werde ich ein eigenes Rig bauen, aber geschlossen (wegen Staub, Lärm) dafür mit optimierter Kühlung. Was ich noch nicht ganz raushabe ist, ob es sinnvoller ist jetzt ein grosses Rig mit ca. 10 AMD Karten aufzubauen oder lieber ein Rig mit 5 Karten (hat sowieso überall Maximalbestellmengen) und dafür noch ein weiteres Rig mit Nvidia.

Hier mal, was ich rausgesucht habe, taugt das was?

GPU: 5 Stück bis 7 Stück (Bestellung eh auf 5 limitiert leider)

Karten betreiben?

Netzteil: Falls ich 5-7 GPU betreibe, lieber 1x NT gross oder 2x NT klein?
