It's unprofitable with a single GPU alright.

However if you happen to have multiple ones sitting idle, you may still find mining profitable for quite a while.

When earnings drop to under 1 BTC per day at 5ghash/s+, then the vast majority of the community will prob. stop mining if the price doesn't keep up. At these hash rates there are maybe a few hundred miners at best, and a lot of those are semi-professional ops.

IMO price is everything when difficulty increases. It will determine the total hashrate of the network. If price just plummets or stays at $20 then yes there will be much less miners in 3-4 months when difficulty is 7-8 million.

The hashing power doesn't come out of charity or goodwill, to keep it secure. Miners have expenses too and blocks are meant to be a reward. If it spreads out too thin and the value doesn't go up, people will find they are wasting their time.

You don't even need a dummy plug.

1. Start miner on 6950 as usual, make sure it's running.

2. Plug monitor cable to 5770 and start miner, make sure it's running.

Then just re-plug it to your 6950 and do whatever you want. The card will keep running despite there being no monitor now.
The client only needs video signal for the initial start.

He does have one valid point though in the 'others' section: Prices tend to historically go crazy during weekends.

Probably because depositing and withdrawing is made harder, or some other inexplicable reason.

It uses max. 525 watts of power, costs more than a 6990 and is essentially as fast as a 6990 in OC mode.

Don't really see how it's going to be useful for mining unless you get one for free. It even requires 3 power connectors.

Well, you are overclocking a laptop circuit above 100mhz it's base frequency and running it at 105 celsius. Maybe the hash rate really is possible.

I'm thinking that's a big waste of a laptop though. Most people don't like to run their hardware at even past 80 degrees due to long term damage.

Meh, I'm not a racist. I just mine as long as the cost outweighs electricity expenses.

If it ever goes below that point, difficulty will adjust downwards most likely.

1. There is no laptop gpu capable of outputting 166mhash/s. Radeon 6970M is the fastest one and fully optimized it yields 110-120mhash

2. 100C 24/7 will kill your chip within weeks

3. A single rig with 4ghash/s would require 12 gpu's = 6x radeon 6990. Not possible by any other combo, even if your mobo has 8 slots, filling them all with 6970s would give about 3200

There isn't even an XL-ATX motherboard that can accomodate 6 dual/triple slot cards without using a bunch of extenders (you'd then be drawing 450 watts from the motherboard power connector just to feed the PCI-e slots which isn't very healthy)

Use Clearcoin or ask one of the forum moderators or Morpheus to act as an escrow especially if you deal in larger sums.

1. Both send their end of the bargain (non-reversible currency) to moderator.

2. After received, moderator sends BTC and currency to respective parties.

Yes. Tianhe's current computing power is made up of 7168 nvidia tesla 1070-series GPU's which would equal about 1 terahash/second, or only 1/7th of the network capacity.

So the bitcoin network block chain can't be attacked by any (known) supercomputers in existence and a 51% attack would require most of the supercomputers in the world.

Also, the bitcoin network is growing in computing power exponentially. Tianhe-1 will most likely stay at it's current limits until they build something better.

So you think $200 dollars justifies a 40mhz overclock you could perform in afterburner in 5 seconds?

The world needs more customers like you; No more recession. Call Bernanke.

376 to 395$ AUD, lol.

Not really, at least anything as profitable. Then again, if price does keep up with difficulty, bitcoin mining will be with us for a long time.
If it stagnates at $20 while difficulty goes into 8 million, then yep, it's going to die until diff. goes down again.

If you want to go in the grey market though, a nice BTC cluster could be useful for cracking MD5 hashes or various passwords.
Some people will pay for consistent daily performance.

The Bilderberg conference isn't some freemasonic league of evil like certain conspiracy nuts like to believe.

Hell, most of the participants are ordinary ministers and elected officials who have next to no wealth and live normal lives besides their work (or even had no power at all before their work in business or politics).

Sure, there's Bernanke and some billionaire tycoons. But most of them are quite plain. There's even a few guys from universities.
The attendee list is completely public and can be viewed online.

Yes, but they didn't seem to work as promised when I first set up rigs ages ago.

For example Phoenix with those flags doesn't produce even near 830 mhash/s overclocked (415 per core), yet the guide claims it does.
Well, not a big deal.

It's a home operation, not a "real pool" in a data center.

However it's good variety when the bigger ones are down.

Wow.
You sound exactly like one of those middle-aged drill sergeants from Vietnam.
Sure you weren't in the marines?

Do you go online with a large pocket calculator and 28k dial-up?

Sent you a few bitcoins.

Those 4 are funny as viral meme videos, but become stale as background music. Thanks for the effort though.

3 of my rigs have a 6990 each, and they're pulling about 730mhash/s each on OC mode for about 3 months now.
From what I gather though, some optimization can put it higher.

Ideal flags/windows client?

I'll send a few bucks worth of bitcoins to best answer.

If it says none, then you really had 0 shares that round. If you recieved even a small payment then you had at least 1 share.

It's very common if the round lasts only some seconds, no matter how much hashing power you have. It's a luck of the draw.

This makes sense. While hobbyists will probably have an easy time swapping pools, for people with multiple rigs it's a pain to reconfigure all of them.

Just add a hidden server address to people on the member page after their hashrate is 1.5- 5ghash/s or more.
To prevent it's leaking (or rather the effects of leaking), require past 24 hours hashrate to be over 1.5 to 5 ghash/s+ in order to connect to the server.

Because top contributors lose significant money during downtime.
