Hey guys,

Im planning on building my first mining rig.
What do you guys think about my planned setup, any improvements needed?

CPU: Intel Pentium G4560 2x 3.50GHz So.1151

GPU: 6x 4GB AMD Sapphire RX580 Nitro+ (Samsung Memory) H/2xDP/DVI (im still thinking about changing to 6x 8GB Asus Radeon RX 580 OC Dual Aktiv PCIe 3.0) // any recommendations?

Power Supply: 1200 Watt Corsair HX1200 Modular 80+ Platinum

Mainboard: ASRock H81 Pro BTC R2.0 Intel H81 So.1150 Dual Channel DDR3 ATX Retail

Im getting the sdd, ram etc. from my old pc.

Thanks in advance!

Seems good to me, I have RX470 and RX570 and working great... But, if you have option I would definitely prefer 8GB version of GPU. 

Thanks for the quick response!
Ok, and whats the advantage of a 8gb one? I mean the price difference is around $50..

Do you think this rig will last for a long time until it may get unprofitable?

I bought last year 8GB RX470 and after few months I bought 4GB RX570 and I’ve got better numbers with 470 and its also better for future, RX470 run just smooth,, there are opinions that 4gb shouldnt be sufficient in future and also you will sell 8gb version for better money in future. But its only for your consideration, I have both and will definitely choose 8gb again if there is not too big price difference.

Alright, Im gonna go for the 8GB Sapphire Radeon RX 580 then..

BTW: when will they release new ones?

I don´t know, there should be some RX580X release as I read somewhere, but someone will be more informed...

dude, right now ethereum is the most profitable coin and the cards need to load the whole DAG file into the ram of the gpu... every 30,000 blocks the DAG file grows by 8,5mb so one day the 4gb ram will be too low to mine ethereum and you will be forced to mine other coins... so if its only 50$ then spend it on the 8gb ram gpus...

Nice plan rig mining. I can suggest / prefer please to take RX570 8gb version, that's more suitable for next future mining. And for the other hardware, i think that's enough for mining rig. And please to use minimum 4gb ram and 132gb ssd, for more comfortable your rig. Happy mining :)

Bitcoin is heavily dependent on this mining process. Due to the mining carried out by miners Bitcoin will validate every transaction, build and store the new block into blockchain. To save the new blocks into the Blockchain, miners must reach consensus.

if mining on Ethash algorithm like ETH still has the status "POW" and have Dag Size more 4GB then you still can mine ETH but if your GPU has 4GB (VRAM of GPU) then you can not mine it.

no one knows except just a prediction.

Good configuration, I hope it will mine 300 to 500 USD per day.

It wont reach it, this is purely a dream, and impossible as of the moment

current profitability for 6x RX470 is around 10bucks per day

Lol

As @leonix said

Are you a GPU miner?
If yes, of course, you have mining farm but i hesistate to get $300-$500 per day for the above configuration although "a hope" nonetheless, should see the reality (diff, hashrate, coin prices) for now.

Thanks for alle the responses! I really appreciate it!
Im gonna keep you guys posted.

One last question: The electricity cost in my country is really bad.. I need to pay nearly 0,28 USD/kw/h..

Do you guys think this should be a reason not do it? Ive done some calculations and right now it still seems profitable...

Any ideas?

if Eth 100x's all of a sudden you might get this for half a day lol

I'm sorry, but this is the WORST moment to buy cards

Asics
FPGAs
New gen Cards
Cards above MRSP
High Diff on all coins

 ;D ;D ;D

That motherboard and CPU are not compatible (socket 1151 CPU and socket 1150 motherboard)

This is the correct one:

EDIT: Also, if you re-use your ram is it DDR4?

No its not, the worst moment was 2-3 months ago. FPGAa are only rumors for me for now. They may become real players or they may not. Speculations. ASICs are real ofc, but my GPUs are still very profitable.
Hi diff on all coins? Exagerrate much?

GPUs are still the kings of flexibility. If you love mining you can earn good money still. But its not plug and play. It takes a lot of dedication, tinkering and research.

Even with electricity cost around 0,30$/kwh?

No, it is the worst time to buy new GPUs right now. There are some many threats to new mining operations that if you actually did "dedication, tinkering, and research" you would have found out the following:

1. The Equihash ASIC will result in decreased GPU profitability for ALL coins/algos
2. The Ethereum switch to POS will significantly decrease GPU profitability for ALL coins/algos
3. New ASICs are being developed for ALL coins/algos and this also decreases GPU profitability
4. New GPU versions are coming out in June/July. That is less than a month away and your new GPU will automatically decrease in value.
5. Etc, so much more, do your own research kid.

Regardless of how you see it, we are actually trying to help you. Although sometimes i wonder what for..

If you know what you are doing yes. I have 10 cards in 2 rigs and 2x R9 380 cards in 2 PCs. Those two only mine occasionally. In the righs I have 4x RX 470, 5x RX 580 and one R9 290x. With that setup I am getting around 20$-30$ per day on average. Some times more some times less. I pay around 5-6$ of electricity per day with 0.15$ cost. So yea you would still earn some but you earning will be greatly reduced. So your margin if prices go down is slim.

I am going for solar energy very soon. If you have means to do that its the best action as it gives you free electricity basically. In your case it would be especially sound investment.

Thanks guys, I just bought 5x Sapphire RX 580 Nitro +.

Now my question :D - whats the best way to overlock it? Just by using msi afterburner?

Mod the Bios

I beg to differ, there are already people running FPGAS. Just read the threads posted on these forums. FPGAs are already upon us. They will only be released to the mainstream public onnly once they are no longer extremely profitable and everyone will be buying hand me downs.



Ouch. You better start praying that you get more time to mine on those. GPU miners are on borrowed time because of all the threats of ASICs, ETH POS, FPGAs, and even the incoming new series of 2018 NVIDIA GPUs.

Can´t share your worries. I want to focus on XMR Mining and don´t see any big danger for future mining since Monero, as a example, already did a hardfork in order to prevent ASICs increasing the difficulty to fast..

I know that RX570 works for 4 GB, but it's better to 8 GB. 4 GB may be small. I read that there will be another RX580X.

that's a good argument to survive from ASIC sometimes you have to try to mine in Ethash algo (RX series) like ETH even though Bitmain release "Antminer(ASIC) E3, Batch 3" it doesn't have to worry about that.

It depends on what coins are you trying to mine. If you would like to mine coins that are using the DAG file size (like ETH, ETC) then it would be good to switch to 8 GB memory for it to still work in the future.

I would also go for high frequency RAM, this also helps a lot.
