Hello Smiley

I understand that a NVidia card is of course not optimal for mining due to it's inherent lower MHhash/s speed, but if you are stuck mining with a 560 Ti (bought it for gaming, then decided to go mining later, whatever), here is how I increased my hash rate from 90MH/s to 108.2 MH/s:

In NVIDIA Inspector 1.9.6.5 (http://downloads.guru3d.com/NVIDIA-Inspector-1..9.6.5-download-2612.html), click "Show Overclocking" then confirm that you understand the risks.
After this, set your:
Memory Clock: 1382 MHz (could go lower if you want)
Shader Clock: 2053 MHz (much above this and it is unstable)
Voltage: 1.050 V

Click "Apply Clocks & Voltage" and start up your miner and see if it is stable. If not, adjust the shader clock down a tad until it becomes stable for more than a minute or two.

Don't have much time right now, but later I'll go through and see if I can't push it to ~110 MH/s, I'll update this post if I am able to.

P.S.: At this clock my GPU stays at around 70C, so I think I have still a fair amount of headroom for chaining settings.

the question is electricity.  your probably paying to mine bitcoins.


You should really put a killawatt on the rig, you sound close to breakeven or even negative profitability.

This calculator says your loosing, even at 200 watts.

Care to share your secret for the benefit of mankind ?

Are you using permanent magnets or antigravity ?

This is ethically and morally reprehensible.

You are in effect just stealing from your parent's wallet.

Exactly. Since you are stealing electricity indirectly why not become the power company for your neighbours and / or neighbourhood and get the dough REALLY rolling it.

Hint : if somebody is paying for it, it ain't free !

No, I am sharing my bitcoins with my parents (just split the purchase of a bitforce single with my mom, they are perfectly aware about mining.) I guess technically this means that I am in essence paying for the electricity, but the addition of a 5970 that is all mine to my system doesn't cost me extra and my parents support my venture.

I'd agree that it was stealing if they were unaware of it or I was using massive quantities of electricity for a mining farm, sure, but one 5970 plus a bitforce single, both that they know about, not, in my mind, is stealing.

If you continue mining with the 560 you will be losing money. Period.  You'll make more money from it sitting on a shelf.  @ 200 watts, you can run a 7970 and get ~600 MH/s  6x the output as the 560, yet half of that income is paying the electric bill.

example.  It costs 3$ to run either a 560 or 7970.

560 will yield 1$ return.

7970 would yield 6$ return.

Net profit?

-2$ with 560
+3$ 7970

Go buy yourself a can of monster instead of running that card Smiley

Bullshit

His parents give him permission to use the computer and he just does that: use the computer. The computer use electricity? Omg, is it a breaking news?

Alright, purchased a 5970 Smiley.

I know you have.

If you run both, you're paying to run the 560 with the money you're making off the 5970.

Think some more.

You may profit a dollar with the 560 and 5970, but if you only ran the 5970, you'd have three dollars.

one dollar < three dollars.

(example of course)

now for mafs.

560 produces 110mhash/s using 200J/s --> 110mhash/200J = 0.55 MH/J (actual load is 0.38MH/J, but we'll ignore that)

run for 24 hours...

0.2kw * 24h = 4.8kwh

I pay $0.13/kwh --> 4.8*.13 = $0.624

Current difficulty--> 1733207.51385

calculator from http://www.alloscomp.com/bitcoin/calculator.php gives us 0.06BTC/day which is .... $0.32

You may pay more or less, if so, redo the calculations.

You let someone barrow your brand new 'shiny' lawnmower that uses 1 gallon of gas per hour.

That someone mows 3 lawns for $15 each in 5 hours and runs the tank dry.

I bet you're pissed, because you lended it to him filled with 5 gallons.

you've lost $20, while he gained $45.

Although, in this case, he's made $15!  Try getting $20 out of him now!

Next time ask him to pay you the fuel he uses

It's like giving a lift to your friend with your car, you can divide the fuel expense with him instead of paying all yourself

That is irrelevant.

Your friend takes you to a bar.  You offer to buy him a drink (using the computer).  You do.  The rest of the night, he sneaks behind your back and orders 5 more drinks on your tab (running a gpu farm).  He walks away drunk (bitcoins) while you are forced to pay (electricity)

My parents are perfectly aware of the mining. They are aware of the power consumption. I even asked them, they said they were fine with it.

BTW I am going to get the 5970, stop mining BTC on the 560 Ti, make the 560 Ti used for gaming or something.

Sorry I opened this can of worms...
