Making a profitable rig for altcoin

[btcrich]

Electricity at 5 cents ker kwh is quite cheap and you can probably be profitable at that rate.

In regards to temperatures, from November to February, you look to be fine.  A few rigs will even keep your home warm during the colder months...just have a couple fans moving air away from the rigs.  In the summer, when temperatures in your house get above 25 degrees C, you're probably going to want to clock down your GPU's or run an air conditioner. 

Keep in mind that some cards run cooler than others, even cards of the same make and model.  I ordered 30 5870's last year.  At 100% the cards ranged from 54 degrees to 120+ degrees with ambient temperature of around 20.  I returned 15 of the cards that ran above 80 degrees and only kept the cool ones.  Then again, I ordered these cards directly from a factory here in China and quality control is not a concept that the Chinese quite understand yet.  Hardware is cheap, but close enough usually cuts it here.

Also, back when I first started mining, it took a lot of tweaking over several weeks to get the systems stable and be confident that they will mine 24/7.  I'd often wake up to find several rigs crashed over night, sometimes from silly oversights but other times for no apparent reason.  Eventually you iron these small issues out, but still today a system might halt after a few days and I still don't know why.  Some people have scheduled in automatic restarts every x hours for this reason.

For the mining, multiminer auto-restarts .

FTC has been the most profitable for me for the past few weeks.

What pool are u using atm for FTC? Anyone recommend a good pool?

Now that would mean I would need to invest 1100$ As I need to just upgrade my motherboard and GPU's? Or is there a more efficient of mining to get 20000 INR at least a month, as I need to start earning ASAP.

Sell yourself into the sex trade.

Mining is not a profitable venture.

what he needs is obama in his country.
but since there is no obama i take it he wanst the rigs to get him the money..
get a  job   buddy..  and support your grandparents

[The Goat Master]

I don't think it is profitable anymore

[aetos]

How much do you pay for electricity in India?  What's the average temperature in the room where you'll be operating your rigs?  You will not be able to run your cards at 100% if you can't keep the room cool and the air flowing.

1st question: $0.05 KW/h but it is ok because if it ends up too high, i have a house which is connected to Golden Temple (I am very lucky to have such a ancestrial house right next to it) and that had (im not joking) free electricity, but i prefer having it in my current house, which is also powered by Solar Panel
2nd question:
Here you go:
Also please do tell me how to keep it cool, because I dont want it to go bad, or not work at 100%. Currently year round, the rig is at 66 if idle, and 74 when mining (celcius).

Thanks for the advice

if its such a privileged to be next to that temple than there must be tourism  exploit that aspect

1. I am 14 years old.
2. My dad is a diplomat overseas, and I stay with my parents, but my dad hasn't been helping my mothers side parents so that is the reason why
3. We have a man called Narenda Modi who is equal or better than Obama, and he will win elections next year
4. This will get me more money than a job, provided I can get a lot capital

For ur reply above, it is a privilege, but it's on the backside, and we never were interested in such business.

sorry kid. i love your enthusiasm in easy money.. but having told this to many  .. education is your way out.. do not learn to depend on the easy way and  get rich quick schemes..
in india with the capital required to start your rig you can  start a consulting bussiness and making rigs for other people..  or fix pc something but educate yourselffffffff

by the way if you think and  comparing your guy to obama you are in for bankrupsy..

GPU mining is not profitable anymore, I am waiting for ASICs capable of doing scrypt.

[nwoolls]

MultiMiner can help you on the software side.

• It can be configured to automatically mine coins based on profitability, difficulty, or price
• It supports GPUs, FPGAs and ASICs
• It can act as a Stratum Proxy, allowing you to monitor and control (and automatically mine using) Erupter Blades, Raspberry Pis and more
• It allows you to monitor and control your mining from your smartphone (using MobileMiner)
• It runs on Windows, OS X and Linux
• It supports any Scrypt or SHA-256 coin and any pool
• It can use either bfgminer or cgminer as a backend and automatically updates both (and itself)
• And it's Open Source

Would this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150671 run at a faster hashrate?
Its a XFX Double D FX-795A-TDKC Radeon HD 7950 Black Edition 3GB 384-bit GDDR5 PCI Express 3.0 CrossFireX Support Video Card
Its different to the other ones it says its 'double d' and compared to the normal one:          
                                   Normal                                             'Double D'
Core Clock:                   900 MHz                                      Core Clock 925 MHz
Effective Memory Clock: 1250 MHz (5 Gbps)                       5000 MHz
OpenGL                        Yes (4.2)                                     No
DirectX                          Yes                                             Yes        

EDIT: or should I just take one of these:

($199 and also 5000 MHz, but refurbished)

 (Does not include crossfire cable, $200, and is also 5000 MHz)

XFX cards run really hot and in my experience are some of the slower cards on the market. The warranty is the best, they never argue when I have a problem and it is lifetime. I had a fan go out on a card, they sent me a whole heatsink with fans, they said I can use the 2nd fan if one of my other gpu fans goes out. lol

Sapphire/Gigabyte are going to be your fastest cards, I do not have experience with MSI but I have heard they are right up there with Sapphire/Gigabyte in performance.

You would be very lucky if you found one for sale new with unlocked voltage. If you don't mind not having a warranty you can get a good 30-40% off of the retail price buying used at auction on ebay and depending on how old the card is you have a better chance at getting one with unlocked voltage.

If you go with MSI get the 2nd one since it has dual fans.

Calculations
However when I mine worldcoin on 100 KH/s, for about 1400 minutes (23.33 hours) it only gave me about 25 WDC which is about 0.00275373 BTC at current exchange rate which is about $0.4 at the average rate of $156 / BTC, meaning I do get more than what it says on wheretomine.com So, that would mean that if I was mining that long at 3250 KH/s I would have gotten $0.4 * 32.5 = $13 a day x 30 for 1 month = 390$ x 61.13 for INR = 23140!
I am not taking electricity into account, because in my locality it is dirt cheap  

Your calculations are absolutely wrong. And there is not such thing as "dirt cheap" electricity when the income is so low.

Okay well it is very little as we use solar water heating and he have 10 solar panels generating 230 watts each so dont worry

I think i will go with MSI, if I dont find a good deal for a voltage unlocked one. Thanks a lot on that, I was tempted for the 1st one since it had cross fire cables and was cheaper and was refurbished haha, but you are right, it would be better to have dual fans to keep it cool.

If you go for MSI, get the Twin Frozr III. It's the best card, runs the coolest and hashes the fastest. It's also voltage unlocked, unlike Gigabyte's garbage.

If I get a good deal then I will take that
