In two days i'm stopping GPU Mining !

[Roland68]

Due to the new difficulty coming in 2 days, my mining rig (3 x 5830) will cost more power as BTC revenue.

It will be cheaper buying the coins ...

for information:

Power consumption of the 3 cards 300 Wh ( about 35 euros / month)
With about 900 Mh I get (now!!!) 0.7 BTC /month = 60 euros *0.7 = 42 euros.

game over!

why not just turn direct it at something more profitable..... like litecoin, if i had a GPU rig i would have done this ages ago.... people like you are contributing to the ever increasing difficulty by not moving on

I don't understand people mining bitcoin with gpu 

Altcoins are 175% more profitable on average. Often reaching 200%.

When mining Bitcoin you can downclock your memory and save heaps of electricity. With scrypt coins you can't.

The game is not over! Bitcoin is not about mining! Mining is just there to secure the network.

If you got Time to point your Miner to the most profitable Coin, it still makes some sense
but you have to be up to Date with the newest Coins.

Wise move...move on !

You can undervolt the same on SHA and scrypt

But then your GPU overclock is very limited.

Rubbish! With SHA-256 I can underclock my memory down to 150MHz. With scrypt I have to overclock to get good results.

Especially for you (dumbass): underclock allows undervolt. overclock ... not.

May I suggest my front-end program, Crypto Miners in Tray: https://bitcointalk.org/index.php?topic=149442.0
It can check profitability data from CoinChoose.com and fire the most profitable miner in your configuration.

I tried ltc mining for a week, mined about 8 litecoins, sent them to vircurex and exchanged to fiat. Problem is how do you get your money out. Also, yes theoretically you can make more money with altcoins but I didnt see it, during the 5 days of mining ltc.

Now, I am back to mining btc, much much better and more convertible even with monsterous difficulty and downward orice.

You can change litecoin into bitcoin and then send the bitcoins to your favorite exchange.

[Nemo1024]

Mining an equivalent of about 0.7 BTC per 10 day period, when converted from LTC (2.1 LTC per day). When I stopped mining BTC directly two weeks ago, I was getting only about 0.4BTC per 10 days.

good for you buddy start bumpin it up!!!

You could always exchange them for BTC, then sell them locally on LocalBitcoins.com.

What is wrong with you ?

The main factor to reduce energy consumption is undervolting the core voltage. The core clock and the memory clock are something else.
Almost the same settings can be used concerning core voltage and core clock for SHA and scrypt. Only scrypt need much more memory clock.

You can undervolt AND overclock = reduce consumption while increasing hashrate. It is a matter of balance and testing.

Moreover, it doesn't matter that you increase energy consumption if your gain from mining altcoin is much higher.

You guys are talking about two different things, and acting like their the same.

BTC can underclock the RAM, while LTC needs high RAM speeds. This is known. However, this has nothing to do with undervolting, as no one I know of undervolts their RAM. I think only a few handful of GPUs can even do it.

For undervolting, we're almost exclusively talking about core (engine) speed. The lower a core speed, the lower it can be undervolted. BTC mining needs a high core speed, so usually undervolting is out of the question if you're going for max OC for performance. You can sacrifice performance by lowering your Core clock and undervolting, which is what most people do at this point I think.

LTC can actually get away with a lower engine clock, IIRC, as it's the relationship between the core and mem that matters most, not the highest clock you can get. If you can get away with a slightly lower clock and still get max performance, you could prolly undervolt and save some power. However, the increased RAM speed will add a significant temp/power increase that isn't negligible.

Now kiss and make up.

Does under/overvolting have any significant impact on the power consumption of a GPU mining rig, anyway?

did you stop?
