I believe what moa tried to say was that you have to use the Radeon BIOS Editor (under Windows) and flash them.

You can try making a file called /etc/rc5.d/S50bcminer and putting the commands in it. Make sure it is executable (chmod +x /etc/rc5.d/S50bcminer). The GPU miners require the X-server, but it is only started when the computer reaches run level 5. rc.local is executed at run level 3. Putting it in rc5.d with that name makes sure the script isn't run until the server has started and everything else has been loaded. The S50 part is there because the files are executed in sorted order, the rest (bcminer) you can change to whatever you want.

90 degrees is very close to the edge, I try to never let it go above 80 degrees by manually controlling the fan speed. If you're very close to the edge of where it will crash (20-30 MHz below) or you're over volting it should be even lower.

The CPU probably uses noticably more power when it calculates hashes than when it's just displaying pictures or transfering data. Even though it's not very much, it's unlikely that you earn enough from hashing to cover the extra power consumption.

The size of the economy does not increase because the value of bitcoins gets higher, it increases if there is more trade. People who hold on to their bitcoins do not contribute to trade. The value of the bitcoin compared to other things is just a reflection of how much competition there is for the coins that are available for trade, it does not say anything about how large the total economy is.

But then I didn't say so, and since this is a smartass reply to another smartass reply I'm not going to elaborate either.

If I'm keeping the currency to myself then I'm doing the exact opposite of providing liquidity.

You may already know, but the wish for a currency with limited supply and anonymous payments is driven mainly by ideology. For the followers of this ideology, no price is too high if they think it gives them what they want.

No, I really meant 155, but I was a little off. It's at 160. I start Afterburner, put it to the lowest memory clock, exit Afterburner, rinse, repeat. I noticed I got a little higher Mhash with higher memory frequency if I specify -v, but it's still a lot slower than with no -v. I use Stream 2.2 and 64 bit W7.

The amount of currency will be the same, but the amount of available goods will increase with (increase in productivity) * (increase in population). This will most likely make the value of currency increase more than you could expect in return from an average investment in production.

Just like there aren't enough speculators in the gold market to stabilise the gold price?

The reason why people preach diversification is that you can't really know for sure what will be valuable in the future. If you do, diversification is stupid. Of course, in any economy you would diversify a little, but if you expect the currency to increase more than everything else in value, the rational thing is to keep as much exposure to it as you can afford, and not trade it away unless you have to.

Unless they inherited their money, which is the case for about 3/4 of the wealth in the US today.

That's weird. On my 6950 I only get 150 Mh with -v -w 128, but 310 Mh with -w 64 -f 1 and no -v. You can save some power by lowering the memory speed. I'm running memory at 155 Mhz with no loss in Mh. Perhaps you have one of the new 6950s with 1GB RAM, or you haven't unlocked the shaders?

They could, but if the people who have the limited resource (the currency) were smart, they wouldn't. They know that productivity and population will only increase, but the amount of money will stay the same, so unless you come up with some unusually good way to produce something more efficiently, keeping all your wealth in currency will be the best way to get richer. Of course, people seeing this will make them over invest in currency, creating bubbles. At some point it will burst when somebody starts selling, the price falls and everybody panics. Then the same will happen all over again. We see this cycle in the gold price, and it will also happen to bitcoins.

Currency trading is a zero sum game. If anybody found a way to reliably beat the odds in this billion dollar market, do you really think they'd sell it this cheap? Unless you're very lucky you'll lose money after fees.

Many professional offsite backup solutions can be mounted locally, so all that would really be needed is the possibility to add a second location to save wallet.dat. This would be very helpful for most solutions. Personally I would save it to a home server, but even just saving to a different drive on the same computer would help in a lot of situations. I'd rather have the ability to password protect the wallet than built in offsite backup support.

You can log in using SSH and control pretty much everything, which means you can access all the functionality even from a smart phone with an ssh client. If you run your text mode programs using the program screen you can disconnect and reconnect later to the same session. Main drawback (for miners) is the lack of an Afterburner equivalent.

I've found 2 blocks and earned about 185 BTC (+10 unconfirmed).

ATI cards will undervolt by default when they run in 2D mode (lower frequency), so it's quite possible. Unfortunately the only way I can do it on the cards I have is by flashing the firmware. If you're lucky Afterburner can do it on the fly.
