It only consumes about 100 watts while mining :| Literally any 250w+ desktop PSU can run it with a single molex connector

Ignore what the box says, that's just an extremely cautious recommendation for the entire system
it even says on the 6990 you need a 750W psu when it consumes 375W

Maybe you didn't realize there are tens of thousands of other people with tickets and issues as well. The site also deals with about $1 million per day in volume.

I only withdraw via wire transfer from Mt. Gox, never used other methods.
My longest transfer so far has taken 10 business days, and the shortest one 1 business day.

Received 2 transfers yesterday (Friday) that were initiated on Monday.

Considering people on other topics report getting their money at the exactly same time always, it's 100% certain they are sending them out in batches
(i.e. they have a certain time of the day when they send out their max. amount of allowed transfers by the bank)

The money can come from Sumimoto Mitsui Banking Corporation or Macaraja SAS but I only got money from Macaraja which is prob. slower.

In case someone is still out of the loop, dummy plugs are now redundant.

AMD is fixing the issue with the 11.7 drivers so GPUs will be detected without being plugged into monitors (or dummy plugs being used).

You can already download the 11.7 preview drivers online.

FireMV/FirePro is AMD's equivalent.

Nvidias workstation cards are superior to AMD cards in general distributed computing by an order of magnitude. Nvidia Tesla cards cost fortunes (up to $20,000 dollars) but have up to 9-30x better performance with up to 4100 gigaFLOPS (4 teraFLOPS) per card.

Compare to a radeon 6990 which has 5.2 gigaFLOPS of single precision compute power. They are 2 entirely different markets.

Workstation cards are phenomenally fast, they just happen to be bad for bitcoin mining.

BBC and Al Jazeera are the best as far as mainstream and investigative journalism goes. They also have a large following in foreign countries regardless of culture and religion.
Deutsche Welle is also neutral and is available by satellite in all countries.

Unbiased, balanced and fair news, even on sensitive subjects which wouldn't be touched with a 10-foot pole by Fox etc.

Voltage adjustments upwards increase energy consumption in an exponential scale.

I'm trying to tell this to people volting their cards to 1.2v (your power consumption will go up about 150-200 watts & you will gain maybe 30 mhash more) but nobody seems to care or they get 'free' energy.

Install AMD Catalyst 11.7 preview drivers, it removes the need for dummy plugs in distributed computing tasks.

I.e. apps will detect GPUs without being plugged into monitors or using dummy plugs.

I'll sell at $16 if you take http://BTCrow.com. You deposit funds, they get locked in.

I send BTC to your address, and your funds get released to me only if blockexplorer shows a successful transaction. If I fail to send, you get your funds back from the site.

It's foolproof both ways, I can't dispute because I get your funds, and you can't make a dispute because the proof is already in the block chain.


There isn't really any reason to decline or make excuses about how untrustworthy escrows are, if you're honestly trying to buy coins.
This method will work 100% and is risk free for both parties.

Meni Rosenfeld or someone else on the forum came up with the idea of SMPPS, or Shared Maximum Pay Per Share system.

You should read up on it, it makes smaller pools practically scam-proof and gives incentive to keep mining even during bad luck streaks. Your share value doesn't depreciate the longer the round becomes, like in a proportional system.

Arsbitcoin and a few other medium sized pools already use the system. The idea of a share buffer means you get paid exactly for the amount of work you do, even if there isn't currently enough BTC to pay for it. In other words, it gives long term immunity against variance unless everyone suddenly stops mining.

Pure PPS is rare because it takes thousands of bitcoins from the pool op as a safety mechanism. I don't know of many sites besides deepbit that have it, and they take a 10% fee for the zero variance you get in return. Tycho can only afford it because his pool has 4-5000ghash/s.

I'm seeing the positive change already, site estimate shows hashrate increase of ~15% and stays stable.

Will this old domain still work after you switch to the new one?

Just rename the file to 'Roller coaster tycoon 1: mac guide', maybe even change or remove the extension, encrypt it & upload to Dropbox.

If you have tons of coins or are just super-paranoid, make russian matroska-type shell container archives, each with their own 60-char passwords, each encrypted, requiring the previous pass to open the next archive which asks for another pass.

Then you can leave it even in your gmail account, memory stick, random upload service etc.

Mt. Gox is a registered company in Japan with a physical office in Tokyo (Cerulean Tower, Shibuya) which pays taxes.

So yes, they are regulated.

P.S. if I were you, I'd be very pissed off, but wouldn't waste a cent on a lawyer. Keep in mind the company deals with $20k+ dark pool orders and huge withdrawals/deposits daily. Their motive to snatch 4k from you is irrational at best.

What you want is money, not revenge. Keep bugging them about it until they send the money.

Or you can even send documents to Macaraja SAS in France and prove your identity; They'll have no choice but to send it. Remember EU anti-money laundering regulations are much stricter than american ones. Banks often have to report even sums past 2,500€ so it's natural they're just covering their own bases.

This is why I never withdraw more than $1000 at once.

Doesn't matter, IMO. A block's value is more than most small pool owners would ever make in fees during the lifespan of the site.

I've been in two small time pools that stole the first mined block & shut down their website. Not a big deal back then considering the block was worth just a few dozen bucks; Now the financial motive is $750 dollars for no work on your part beside hosting a half-assed site.

I'm not implying Sam is such a person, I'm saying the motivation is definitely there.
If not blatantly stealing & running away, then just taking the block & claiming you are undergoing an "unlucky round due to variance" and hoping the miners will just keep mining for you. You get 50 BTC and they'll never know about it.

Big site operators have zero motive for this because they'll make 50 BTC legit with their fees in the span of a normal operating day. They don't need foul play and will actually lose money in the long term if caught. Small pool ops have no reputation or business to lose. They'll make 2-5 BTC off pool fees in a few months if they're lucky.

Spend $164 after rebate and get full warranty & a newer series card, same hash rate.

Of course it's not in stock almost anywhere because it's a 2½ year old series card.

Why do all sellers here try to scalp buyers?

Really. It seems nobody here wants to do honest business. It's all about ripping off someone.

Stock is around 270-277 with POCLBM at stock 725mhz..

380 is a rather high average. I'd say most people can push to 340-360 before it starts bluescreening. At that point the clock frequency would need to be way past 900.

All cards will manage 750mhash average at the least.


Haven't had a single one that wouldn't go to 820 per card, 410 per core. 850 is prob. the max for anyone. Avg. 780 at the least for most people even with bad cooling.

Someone on the forum claims over 900 mhash per card, but I didn't find these results replicable.

Those other cards are spot on

Not really true. Since pool luck only evens out in the long term (after weeks, months, years), you might incur massive losses by choosing to mine at a small startup pool right now.
I made this mistake a few weeks back, joined a pool in which I generated about 360k shares. It turns out the round got into 3+ million shares and nearly everybody ran off.

There are only a few cpu miners left, and if the block is ever found my prop. earning is about 30% of what I'd have earned at a site like deepbit or BTCGuild.

Since there is no 'long term' for those pools (it will die after the first block is found & bonuses harvested) it's a ridiculous gamble. It doesn't pay off anymore.

Of course, I'm naive so I joined yet another pool about 2 weeks ago, btcpool24.com. Turns out the block is prob. never going to be found now that the pool owner removed all bounties & major miners escaped. Another 50k shares wasted.

Yes, it does use GPU if available. Even your video shows that.


Why would your ordinary CPU be 100 times faster than all the other 3 million similar processors in existence?
If it doesn't "seem" to heat up then the temperature diode is broken on the card.

Nope. I get about 405-410 mhash/s per core at 900 or 910 OC.
Had to point 2 table fans at the card to keep it cool, too.

Tbh I just don't see how you could get 450mhash/s with 910 core clock. I'm not calling you a liar by any means, but proof would be nice.

Since all 6990's are reference (they are all exactly the same except for the stickers of the manuf. on the front)
it can't be a hardware issue.
