Bitcoin Forum

hello everyone!!:D i am new here and my question is what hardware you recommended at start to mine crypto-coins ?? i think that GPU mining it's to old right now but i can be in mistake i think to make rig with only USB but can you tell me what motherboad,graphic card and supply power?? how much WAT graphic card and supply power have?? and what about RAM?? please help me ;3 thank you ;))

OP if you need serious advices on your next buy, you should state your total budget for the hardware.
 :)

What cryptocoin do you want to mine? It is certainly too late to try GPU mining with BTC.

The most important thing is the video card. For performance comparision (for LTC mining), see here: https://litecoin.info/Mining_hardware_comparison
Generally, you'll want to stick with a Radeon 7950, 7970, r9 280x or an r9 290x. Those will be the best performing cards. Be aware some brand cards, even within the same model lineup, can perform differently.

For the remaining components, it all depends on your budget and how many cards you want to run. Look for a motherboard with the most PCI-e connections (x16 -or x1, x4 and x8 will also work via an adapter).. quantity of RAM is pretty much irrelevant, so 2GB would be plenty. Most of these higher end cards will run in the 250 - 300 watt range at load, so; (# of cards) * 250 + (~100 watts to cover mobo/cpu/hdd/etc components) * 25% (for some headroom) = about the minimum power supply wattage you'll need.

Without asics hardware you should stay away from sha256 and search for scrypt based coins e.g. litecoin instead.

@WillMilk4coin hhmm the most effective;3(even if the calculations from Crypto-coin will be 1BTC per month i will be happy so much:) )  ..my budget can be 700-800dolars right now but can you tell me if i try to mine crypto-coin with USB(2.0 i don't have so money to buy 3.0 ) only like 2.2-2.7 ghs/s this can be a good hardware at the start ?? and please read this: I DON'T WON'T TO MINE WITH GRAPHIC CARD because they are so cheap right now..and usb price are lowest than graphic card

my hardware i can use:

supply power:OCZ extreme PRO 700W
Motherboard:AS rock N68C-s UCC
GPU:Geforce 550 TI
CPU:Amd Athlon 6400 x2
RAM:2x2Giga DDR2

I am not sure how you will be mining with a usb?? Are you referring to something like a block erupter (http://www.amazon.com/ASICMiner-Block-Erupter-USB-Sapphire/dp/B00CUJT7TO)?

yes i mean this but can i plugin this into my USB port??

Yep! You can plug those into any usb port on any online system. No other hardware is necessary. You can even get a multi-port usb hub and plug them directly into that. Their power consumption is very low, so you don't need any robust power supply.

Looks like we're coming to the end...xD so my current hardware:

supply power:OCZ extreme PRO 700W
Motherboard:AS rock N68C-s UCC
GPU:Geforce 550 TI
CPU:Amd Athlon 6400 x2
RAM:2x2Giga DDR2

with of course with this USB(2.2-2.7ghs/s) can mine crypt-coins with 24/per month ??xD so if i correctly understand i do not need change any components in my hardware??

Correct; if you are mining with a usb miner such as the one mentioned earlier, there is nothing with your system (PSU, RAM, mobo, CPU, etc..) that you need to change.

The only thing you'll be able mine with a block erupter, or any other usb miner right now, is BTC. These will not mine scrypt based coins.

good damn it;/ but if i by rigs like that http://coinreel.com/wp-content/uploads/2013/08/butterfly-labs-5-ghs-asic-bitcoin-mining-rig-the-jalapeno.jpg (5ghs/s) i am be avaliable to mine scrypt coin?? or what i need to buy to mine scrypt coin

In order to mine a scrypt based coin, you will need to run a GPU. There's no other way around it.

ffuu ;(( and what about altcoin?? i need GPU for this??


@edit1:if i have this USB's i can mine any SHA-256 coins??

Those would be capable of mining other sha256 coins, but I don't know what might be involved in pointing them at another coin. It may just be some simple edits in the config file, but I haven't any experience with those usb miners.

ok i understand so the best way to main crypto-coins is buy better graphic card?? for example radeon 7990??(if i like to buy 1only) but my power supply can hold this card??

You won't be able to mine much with 2.2-2.7 Ghash/s miner unless you have hundred of them. Roughly speaking one R9 280x graphic card giving you some 750 khash/s at scrypt today can earn you as much as 15 Ghash asic at SHA-256. But for mining scrypt currencies you'd better also get more RAM (8GB should be enough for 4-5 graphic cards). The only not important thing here is CPU, old 3Ghz would be more than enough (unless you want to mine scrypt-Jane currencies, but there are not too many of them). Your PSU now is enough for  1 graphic card (1200w can handle 4).

HD 7990 or r9 290x is definitely the best card for today.

I have 3x R9 280x's and they work really well, and I'm only using a 1000 watt power supply.

But in reality, they're just rebranded 7970's :P

thank you guys for this PERFECT steps but my budget is not so big right now so if i correctly understand if i bought this R9 280x graphic card(only ONE!!) it will be good to main crypto-coin?? if i correctly calculate on this page..

http://www.coinwarz.com/cryptocurrency/?sha256HashRate=1000.00&sha256Power=500.00&sha256PowerCost=0.1000&scryptHashRate=750&scryptPower=300&scryptPowerCost=0.1000&sha256Check=false&scryptCheck=true

for example i buy this R9 280x graphic card if i must change something in my hardware??(remember only one!!) and please be look at my current hardware set-up

You won't need to change anything with your system using a GPU to mine - as long as you have the available PCI-e slot and enough power. You shouldn't need any more than 4 GB of RAM. I am currently running a 5 280x rig with 4 GB right now without any issues whatsoever. For a r9 280x, you should be covered with the power supply just fine as well.

thanks a lot a lot a lot a lot xD you are my sensei's ;DD and i am your beginner padawan ^_^ for example if i have ASIC usb 2.7ghs/s i mine with power like this?? and if i have 2xusb with 2.7ghs/s i have 5.4 ghs/s mine power?? i know that sometimes rigs gpu cpu can differ from ghs/s and rest of units like khs/s mhs/s

@edit:can you tell me i calculate correct how crypto-coin i can mine with 500khs/s??

http://www.coinwarz.com/calculators/galaxycoin-mining-calculator/?h=500&p=500.00&pc=0.20&pf=0.00&d=0.25496726&r=64.00000000&er=0.00002000&hc=0.00

@edit2:i know that ASIC usb can mine crypto-coins

Hey man as a consumer just starting up, I strongly advise you to mine scrypt. And if you do,use AMD GPUs. BTC mining is solely in the realm of elite asics now and unfortunately scrypt may head that way soon also.

The usb miner will draw the power it needs directly from the port in which it is plugged. They only draw a couple of watts, so there isn't too much of a concern in supplying enough power. However, be careful which usb miner you would buy as some require the additional power from usb 3.0. If you only have usb 2.0 available, you'll need to look for something that doesn't exceed 500mA. I haven't kept up with all the specs of the different usb miners, so you'll just have to verify the power consumption on the miner you're looking at. There is no loss from adding additional miners; so yes, if you had 2 that each did 2.7 Gh, then you'd have a total of 5.4 Gh.

Generally speaking, the standard unit of measure for BTC is currently in Gh/s, but that will be changing in the coming months to Th/s. For scrypt mining, such as LTC, the standard unit of measure is an order or two of magnitude back. One video card, for example, will mine in the Kh/s range while someone with even a couple GPUs will be bumped up to Mh/s. It all depends upon what currency you'd like to mine. Those usb miners will only work on sha256 protocols, but if you're calculating for hash speed in the kh/s range, you must be asking about mining with a GPU on scrypt...?

BTC has definitely gone pro when it comes to mining.
There is absolutely no profit to gain by building your own rig unless you are ready to invest a large amount of dollars to invest in pro equipment and rent to warehouse to keep the gear.
Even with pro gear you need make sure 24/7 that the gear is performing optimum, since the margin for profit with BTC mining are very slim, the difficult estimation in 3-4 month basis is also extremely hard to predict.

However when it comes to LTC, then is there still opportunities to make a profit.
But you have to carefully make a business plan and budget before you start, here are some key areas:

- What equipment to buy, obvoustly it must be a AMD GPU's, find a good deal for your budget.
- Where to store the rig, you wife WILL NOT be happy about the rig in the bedroom.
- What is the electricity cost, they should be deducted from your monthly profit.
- Make a budget, and make a conservative estimation of the difficulty change over the next 6 month.
- How much can you sell your gear for, e.g. after 6 month.

If your budget gives black numbers, then are you ready to go and invest in your GPU's, get them up running asap, time to market are crucial.
If the numbers are red, then are you properly better of just buying the LTC. 

@WilkMilk4coin woow you have google.com information in your head??XD dude you are AWESOME!!:D in another forum like bitcointalk.org one men told me that i can mine scrypt coins with USB but they must be from ASIC ONLY!! like this usb:
http://www.amazon.com/BPMC-Blue-2-2-2-7-Bitcoin-Miner/dp/B00GRJUE0Y/ref=sr_1_6?s=electronics&ie=UTF8&qid=1386953134&sr=1-6&keywords=asic+usb

how i can calculate 2 2.7ghs/s usb for khs/s?? and i would like to main crypto-coins like on this page:
http://www.coinwarz.com/cryptocurrency/?sha256HashRate=1000.00&sha256Power=500.00&sha256PowerCost=0.1000&scryptHashRate=1000.00&scryptPower=500.00&scryptPowerCost=0.1000&sha256Check=false&scryptCheck=true

i mean galaxycoin,spots,grandcoin and rest ..

Sorry, but the information from the other person on that other site was incorrect. At the moment, you cannot purchase any usb scrypt miners. The Blue Fury (ASIC) miner you have linked to on amazon is for Bitcoin only; or sha256 more specifically. You simply can't make that miner work on a different protocol as ASIC chips are hard coded to work on one instruction set. They're not reprogrammable, so the algorithm they are designed for initially, sha256 in this case, is the only use it will provide.

If you want to mine scrypt coins, like Galaxycoin; Litecoin; Grandcoin; any of them on that list you linked to, you will only be able to mine them using a GPU. USB miners will not be capable of mining those coins - for now. It has been announced that sometime in early 2014, we will have ASICs for scrypt, but we're not quite there yet.

so ... the forum(another not this) is for idiots and only idiots ;_; and.. this person is admin *.*("idiots idiots everywhere in the world:]")

BTW okey so i find this graphic card:

http://www.amazon.com/Sapphire-Radeon-PCI-Express-Graphics-11196-19-20G/dp/B00CPLI74S/ref=sr_1_1?s=electronics&ie=UTF8&qid=1386956147&sr=1-1&keywords=sapphire+radeon+hd+7950

and this card have 500khs/s and can you tell me i correctly calculated??

http://www.coinwarz.com/calculators/spots-mining-calculator/?h=500.00&p=500.00&pc=0.21&pf=0.00&d=2.33805056&r=49.00000000&er=0.00017565&hc=0.00

if i correctly understand from this website i can mine 1BTC in 27,01days??(i know that difficulty can change about every 12-14 days ;)) )

Dont be so pessimistic, I will believe it only when I see it. Preorders are scam, ignore preorders

I can't say from experience, but I would expect that card to get closer to at least 600-650 Kh/s on scrypt.

Your calculations should look more like this: http://goo.gl/7gdf2B
Power consumption will be about 250 watts;
Looks like the card is retailing for $400;
I included a 2% pool fee if you mine with a pool - this will vary with pool choice, though with Spots, I don't even know if there are pools or if it is only solo mining
I left the power cost at .21$/kWh - you'll need to adjust that according to what you pay

That would be how long you've mined the equivalent of 1 BTC in Spots at the current exchange rate. That could certainly change with any changes in price for either coin.

hhmm that nice ;)) (1BTC per month..not bad right now) what you prefer to start mining?? it's better to mine in pool or just solo??

and can i plug this card to my motheboard??
http://www.asrock.com/mb/NVIDIA/N68C-S%20UCC/?cat=Specifications

Yep, that motherboard will work just fine.

That all depends upon which coin you'll be mining; the difficulty level and the availability of pools for that coin. You can choose to solo mine any coin, but the higher the difficulty, the more luck required to find a block. I've heard that solo mining is not very feasible if you have less than 1% of the entire network hashrate. However, some coins may not even have any pools setup, so you'll be required to solo mine. Once you decide which coin you'd like to try, look through the Alt-coin sub-forum to see if anyone has setup a pool for it: https://bitcointalk.org/index.php?board=67.0

ok thanks for help now for example i have 1BTC from exchange crypto-coins and i know that not all crypto-coins can be exchange at "cryptsy.com' and if i have 1BTC on this page on my account how i can send them to my main BTC wallet??

I don' think you cant get that card to mine SPT at 500kH/s

why u think??.. in other screenshots and forums people write the khs/s on this card differ from 500-650...

BTW what card should i buy?? sapphire radeon hd 7950?? or R9 280x?? what is difference between these cards??

I was mistaken, sorry, I tried mining a few spots to see the hash rate, but I forgot to set the intensity up, so my hash rate was ridiculous low.

What pool are you planing on using?

no problem mate ur welcome ;)) i don't know ;(( i am new in mining and right now i planing to buy GPU(only 1 right now) and what pool you prefer?? or just solo??..

I am only mining LTC at the moment.

wow so your PC must be a beast ;PP LTC difficulty is high ; ))

Not at all, some old scrap:  I have 2 x HD7850 ~ 600 KH/s

*not bad emot* xD i have question 2u my supply power(ocz modxstream pro 700w) can hold Radeon 7950HD or R9 280x??; ) (only 1GPU right now)

Yeah, that should not be a problem.
I run mine on a corsair GS600.

Look at this one, if you not already know it, good for comparing cards, and some of them have powerspecs too:
https://litecoin.info/Mining_hardware_comparison

This page is good too if you are planning in investing in gear:
http://bitcoinwisdom.com/litecoin/calculator

Edit: Just remember that GPU mining is another game than bitcoin asic mining, since the GPU still have some value when then can not generate a profit in respect to electricity cost, then can the cards be sold used, and if you have already reached ROI by mining, then is the sell all profit.

thanks ;)) this pages can help me a lot :)) so if i correctly understand with this card i can mine even 1BTC in 31 days?? of course with power cost and difficulty can change ;))

btw can u tell me i correctly calculate kh/s?? http://www.wheretomine.com/ type 650kh/s and take earnings for top (you should have MEMcoin as first coin)

I cannot say anything about spots, I have absolutely no experience in that.
I tried spot for 30 min, when I saw this thread, i could not mine anything descent.

There are many variables to take into consideration.
1. How much time will it take get the gear up running.
2. Can the gear run 24/7? (dont take it for granted that you can plug it in, and then it will run for 31 days, without some kind of tweeking).
3. How much the gear cost.
4. The electricity cost.
5. The difficult change.
6. The exhange rate on the scrypt you are mining.

If you can earn 1 BTC in one month with a 200-300 dollar investment, then would I say that you have found a sweet "spot".

Remember investment is always the game of risk, there are no sure thing and absolutely no guarantees.
You have to evaluate the risk vs. the opportunity for profit yourself, before making an investment.

1.maybe 16hours?? in weekends of course 48H ;)
2.in the future yes...;)
3.hhmm i only need change GPU and this card cost me 400-450$
4.now in poland there is 0,61 zł so in dolars it will be 0,20$/kwh in 1day it will be 5-4,50$
5.i know that difficult can change ;))
6.for example emeraldcoin (calculate on coinswarz) 0.000129

i know that guarantees can change don't worry ;))

Better to use some stable currencies for planning profit.
For example, begin from LiteCoin.
http://www.coinwarz.com/calculators/litecoin-mining-calculator/?h=1000.00&p=500.00&pc=0.21&pf=1&d=2926.50971494&r=50.00000000&er=0.03476000&hc=400 (http://www.coinwarz.com/calculators/litecoin-mining-calculator/?h=1000.00&p=500.00&pc=0.21&pf=1&d=2926.50971494&r=50.00000000&er=0.03476000&hc=400)
It's your more predictable profit for next month.
After what, you can try something like WorldCoin. Also looks stable now.
http://www.coinwarz.com/calculators/worldcoin-mining-calculator/?h=1000.00&p=500.00&pc=0.10&pf=0.00&d=43.51582338&r=55.59973207&er=0.00070002&hc=400 (http://www.coinwarz.com/calculators/worldcoin-mining-calculator/?h=1000.00&p=500.00&pc=0.10&pf=0.00&d=43.51582338&r=55.59973207&er=0.00070002&hc=400)

So, you have good chance to earn about $300 to $500 next month with your card.
And, I think, it's also great opportunity.
Don't look at most profitable coins. It can be not correct calculations. And even if it happen - this happen for 1-3 days, later profitability will return to the Litecoin +- 30%.

Also remember, as another members noticed already. LiteCoin price is skyrocketed from 2 to 30 USD in 1 month. Thats why is so profitable now to mine scrypt coins.
But next months it can return back or difficulty increase and you will get 50 - 100 USD / month with your card.

I pretty much agree with all of this.

It is much better to budget with something stable like LTC.
More reasons:
LTC is well establish, the p2p network are extensive, software is mature (e.g. litecoin-qt). With prototype coins, expect problems with everything, even to transfer the coin from your wallet to the exchange bay.
There are many mining pools, the top5 are very stable, almost no downtime and great monitor interface.

Once you got the setup working and you got some experience with mining, then can you try to take your miner offline at try out some other coins.

The 1 BTC / month you have estimated was based on a spot diff ~ 2.3

Look at the spot difficulty chart the last 3 days:
http://www.coinwarz.com/difficulty-charts/spots-difficulty-chart

Try recalculate your budget ;)

so ok if i correctly understand if difficulty have 2.3 i can earn this 1BTC right??:P

Yes if you are mining spots with 500 KH/s and:
Electricity cost are $0.
Difficulty stay at 2.3
Your gear works 24/7
Your pool has 0% fee
Your pool has zero pool downtime.
The exchange rate for spots down go down.
ect.

 ::)

electricity cost are $0??XD not in this world ;DD ok thanks ;)) and last question if you have 2 GPU to choise R9 280x and Radeon 7950HD what is your choise??

electricity cost are not $0 from a net point of view.
However some countries has electricity included in the rent, also it is not unusual that student flats, dormitories ect has electricity included in the rent.

Personally I will go for the HD 7950, because of the availability where I live, you can find it used for a good price.

However I see many "pro-miners" use R290x, R280x, R270x.

I think both are good miner-cards, go for the cheapest you can get your hand on.

Good luck - happy mining  ;D

thanks dude ^_^ so i try R9 280x first :D

No problem, matey.

Please share your experience with the spot mining when you have some results.

which coin would you suggest mining? LTC? Or an even younger altcoin?

i think about MEMEcoin and later exchange them to LTC ;)

remember that coinswarz.com and wheretomine.com are sometimes outdated and they don't give you actually difficult etc ;)

BTW for example i how 489374823 on galaxy-coin how i can add them to www.cryptsy.com ?? and what site you recommended me to transfer BTC to paypal?? i thinking about virwox or skrill.com
