T-shirts are not a service.

If mining dies, so does bitcoin. Mining will not die. If mining is no longer profitable, people will stop mining, and the total hashing power of the network will drop. If that happens, the difficulty will also drop at the next reset, making mining profitable again.

I get 2.5% stales with Phoenix, mining at bitcoins.lc

Do you have a website you would like to localize? An application? A book? An article? Or maybe you'd just like to say something in Swedish to your Swedish friend, without embarrassing yourself because Google Translate did a crappy job?

Welcome to my Swedish translation service!
I offer professional translations from or to Swedish. Being a native Swede, my Swedish is of course excellent. My English is almost on the same level as my Swedish. Hell, at one point in my life, I was using English so often that I started THINKING in English half of the time. I also have quite a bit of experience doing freelance translation.

Pricing is done on a per-word basis. The current rate is 0.001 BTC/word. Rate may be increased slightly for particularly complex texts, but this will all be decided upon before I begin working on the project.
Deadline is decided upon mutually. It is dependent on complexity and amount of words.

Also, no project is too small! I'll even translate single sentences for you, if you wish.

If you are interested in my services, simply post here or PM me. Tell me what you want translated, and I'll give you a price quote. We'll also discuss the deadline.

Looking forward to your business!

Thanks, just what I was looking for!

Most likely you will notice little to no difference. Even if you gain a few mh/s, you're likely to have lost more profit during the downtime while installing a Linux OS and a miner than you're going to earn from the extra mh/s.

Hi.

Is there a script or application that checks the temperature of the GPU, and if it rises above a certain temp (say 80c) the fans start spinning at a certain speed (say 80-100%) and then return to normal speeds once the temperature has dropped to a specified value (say 70c)?

If not, this should be pretty easy to do, right? I know some C/C++, C# and Java programming, but I have no idea how to interact with the GPU driver to get temp and fan values.

Thanks.

I couldn't find any ATI Graphics Power Settings, so I'm guessing that's mobility-exclusive. However, I turned off Link State Power Management. I'm not completely sure what this does, but hopefully it helps. My screensaver was already set to none.

I've done some experimenting, and I've discovered that:

1. Sometimes, although rarely, the downclocking will happen even when I haven't overclocked the card.

2. Running a GPU-intensive application, such as a game, resets the card to normal clocks.

I've done the registry hack that RyNinDaCleM suggested, but it made no difference.

Damn, I'm down to 0.3 bitcoins per day now. After the next difficulty increase, mining won't be worth it to me unless the price goes up to AT LEAST $25. But maybe I'll keep mining a while longer anyway, and just hold for a while.

So I've been mining for a while now with my two gaming computers, and I wanted to do some slight overclocking to increase my earnings a bit. I overclock my HD 5850 from core speed 725 mhz to 775 mhz. I gain ~30 mhash/s, and everything seems to be fine. But then after a couple of hours, I see my hashrate drops to 150 mhash/s. I open up the CCC and see that clock speed has been dropped to somewhere in the 400 mhz range. I try setting the clock back to default, I even try underclocking it, but nothing works. I then restart my computer, and everything works fine again. I try again, but the same thing happens.

Why does this happen? Is it a security measure when the card gets overheated? The card runs at between 75 - 82 degrees, overclocking doesn't seem to make much of a difference temperature-wise.

Thanks in advance.

Don't understand why everyone is raging on evlew when he's just cursing at the biggest hypocrite I've seen in a good while. Calling in to get his investment back when things turn bad, consider telling them what the hell is going on so that people won't be able to do the very same thing he is doing (why? Because it's immoral? Then why the fuck is he doing it himself?) but then decided not to do it just to save his own skin.

Why is everyone protecting this jerk?

No, it's fine.

You only have the one that you can see in the Bitcoin client. You may want to backup your wallet.dat, because if you lose that, you lose your money.

You don't need to create a new copy. Just run the miner a second time and select your other device (in this case GPU)

It'll go up again.

The number of shares you see on the site are for the last 30 minutes, not the total amount of shares.

Your shares will be converted to bitcoin when a block is found. You will then have bitcoin in Unconfirmed Funds, which will be moved over to Confirmed Funds after a while.

The address in the Bitcoin client is the correct address to give out when you want to receive payments, for example for pools. It is the only address.

As for the RPC error, that happens when the miner can't connect to the pool. I've never used GUIMiner, but make sure the URL to the pool is correct, as well as the port.

Sounds like you're making it use your CPU.

My brother's HD 5770 only reaches around 130 Mh/s. No idea why. :/

I doubt it will even reach $100. But then again, people said the same thing about it reaching dollar parity.
