[LTC] Seems GPU mining is getting difficult

[FreedomCoin]

I have two 6900s yielding about 900kh, using about 700w of power. With current power costs it seems i would be loosing a couple dollars a day.

With the price not rising and the difficulty rising is anyone else feeling this pain?

[mill0601]

I certainly am

What kills you is that your efficiency is terrible. You're getting 900kh/s out of your two cards using 700w, while a single 7970 can easily run 740kh/s using only 220w-250w. Much easier to mine with those kinds of numbers.

And 7950s provide an even better price/performance these days (I believe)

I just ordered a 7950. Do I need to voltage clock the card to turn it down to 220-250w?

Depends on the card, but usually, yes. Gigabyte and some others lock the cards at 1.25v stock which cannot be changed. This is very inefficient, especially when overclocked.

I'd only use either MSI TFIII or Sapphire Vapor-X 7950 cards as these can be software undervolted using Afterburner or TRIXX (under windows), or in some cases can flash with a modded undervolted BIOS which will reduce the power draw in Linux by between 20w - 40w under full load depending on your other clocks..

With BTC difficulty increasing so rapidly no one knows what the value of LTC should be, before it was pinned nearly equal to BTC and it's been progressively increasing in relative value GPU mining.  2nd gen ASICs that are soon coming out are 100+ fold the power efficiency of GPUs; we might expect that with the rising BTC difficulty, that LTC price may dramatically increase to keep it in line with the cost to produce in terms of electricity.  But this is all up to the speculators who play the market.

try to mine more profitable coins, there are many other coins that profity is 200% of LTC.
and ltc will certanly go up with price.
also look that btc is going up and will go up

[stickerzlab]

If you ordered a gigabyte I'd recommand you to read this very usefull post about firmware downgrading https://forum.litecoin.net/index.php?topic=2641.0

most of them are temporary profitable , not for always

I would suggest you use a multicoin pool like middlecoin, that is what i am moving on to.

Ah yeah it would seem my card is too oldschool at this point, are there any new video cards coming out with a good yield to wattage ratio? Last i checked the 7790 had one of the best ratios. But its a little underpowered for my taste.

Not only temporary....but ponzi scheme.  Get new people in so original starters get profit. What a scam.....


But yes, ltc difficulty is definately rising faster than profitability.  ASICS are pushing BTC miners over to LTC.  Hopefully LTC prices will rise to make up miner profits.  If not, BTC may be the only true coin to mine if you can get a hold of decent ASICs.

what if we can't mine BTC nor LTC? what should we do ?

[usahero]

Move to country with lower electricity cost / sell gpu / speculate on new coins and mine them/...

How about buying?  If you want to make money with crypto coins trying buying BTC or LTC.  Right now it seems like a better investment then mining them.  You could also try selling a service or product.


If you get caught up trying to buy one of the crap coins out there you might be the last one holding the bag.  Most are just a silly trap for all the newbies who come here looking to make a quick buck.

I invested a lot in mining equipments, now i dont have money to buy. I should mine something.

[hendo420]

I currently pay $0.08 per kwh flat rate. It doesn't change.
I have 4,000kh/s and mine about 3.5-4btc worth of alt coins per month.
I mine on middlecoin pool, but If I mined LTC my earnings wouldnt be much lower.
My power bill is only $100 over what it would be not running the rigs.
I know this by comparing my bill to my neighbor in the apartment next door.


So 3.5btc ~ $400 - $100 power = $300 profit per month.

Difficulty still has a way to go b4 I stop mining.

I picked up 2 more 7970s so I'm now up to 5,400kh/s so I should be near $400 profit a month.



Off topic but I supplement my mining income by reinvesting most of my profits back into btct.co, I make more and more in dividends every day. I'm at about 0.012btc dividends per day and have about 0.7btc invested. I plan to invest alot more.

Price is really not reflecting cost of electricity at this point IMO... LTC is low on market sentiment. It will rise long.
