6990 is off by a wide margin.
For 760+ mhash/s you would have to OC past 900mhz so power consumption just for the card itself will be 450-500+ watts

They are buying hardwares and selling internets on the tubes.

The problem is liquidity. Every single other exchange is small fish.

Consider that Mt. Gox got more volume in 3 hours after opening than all other exchanges did in a week.

2 days after opening Gox volume will already be much past the 1 month average of Tradehill.

I can push some of these to about 920mhz, after that they tend to freeze even if I just look at Afterburner with remote desktop for 5 seconds so I don't deem it very stable.

If you are also using the PC for general stuff like surfing or reading forums, about 870-900mhz seems ideal, and you will get at least 320-330mhash/s

Temp of the core doesn't indicate a stable card. The VRM will melt if you overvolt 30% and push clock frequencies +250mhz for 24/7 use.

There's a guy on the forum running 6990's super oc'ed in a ventilated cabinet. He refused to believe the cards could die at 60c. Electromigration and decay of the voltage regulator will still accelerate the card's death massively.

The BTC community is/was largely made out of extreme tech geeks.
As such, there will be a large proportion of people with asperger/autist tendencies, social insensitivity, irritation and other "flaws".

However, were it not for those pioneers, Bitcoin couldn't exist.
They are the few people in the world who, despite their quirks, are capable of sustaining, developing and spreading something like Bitcoin.

I don't know a damn about Linux or command lines despite having a big mining farm. But I realize those people are still valuable and smart.
Of course, if 'we' want to make Bitcoins "presentable" then defensiveness and elitist attitudes would have to fade.

Knowing how money hungry politicians are during campaign time, this might not be an entirely dead idea.

Considering the prospect of hundreds of thousands in potential additional funding, some candidates might be willing to deal with the scrutiny that will fall upon bitcoin after they accept donations in it.

Then again, it could be political suicide at this stage.
How will they convert it to fiat currency to buy ad time etc.?

Reporters will most likely refer to it as money laundering or evil drug schemes based on Silk Road.

Paid, thanks again.

Nice service.
Though, only platinum offers monitoring for 6+ workers so it's not really worth the ~$400 per year IMO.

Eclipse pool for example offers free SMS failure notifications. Still, I'd probably pay around 10 bucks/mo for all the stats you provide for ~40 workers

You just had $10k dollars lying around on Gox before the hack?

Income dropped to under 10 bitcoins per day for the first time on my farm but it still far exceeds the price of electricity.
Don't see a reason to stop until about 6-8M difficulty.

When income is less than a bitcoin per day at current prices then I'd say it's not worth it.

But if you run a small cluster then yes, there is no sense in selling at current prices unless you really need the USD. The obvious thing to do is to wait for a bump to $20-$30+.

Precisely. The vast majority of all sold AMD/Nvidia graphics cards are low to midrange cards for OEM computers, such as Radeon 5450, GT 420, Radeon 5750, GTX 460 etc.

They are also used as dumping pits for excess VRAM chips, so you may see an absurd amount like 2GB of memory on a GT420 for OEM use. It's a very profitable business.

Consider that these 2 companies sell tens of millions of graphics cards per year. Bitcoin users buy maybe 20,000-30k GPU's top
(which is still optimistic, seeing as most people use their pre-bought rigs, and some still mine on CPU's, few people actually build farms).

Ok, miners tend to buy high end cards which is a plus for their bottom line.
But it's still a drop in the ocean for them to care. Gamers and Eyefinity users still buy the majority of those.

If they were really to stabilize at $100, obviously few people would be purchasing or selling whole BTC for their small purchases or daily needs.

You'd probably buy 10 bitcents, or 25 bitcents etc.. Just like you buy an ounce of gold, or a 40 gram silver bullion.

You don't go and buy the whole troy ounce or even a kilogram if you're an average person.

It did already.

You're correct, in reality illegality will deter widespread adaption, at least in the country in which it's been made illegal in.

North Koreans are using tons of smuggled black market US dollars and Chinese Yuans for regular purchases like rice and other food items.
Even though they can face labor camps or the death penalty if caught.

Their own currency (devalued in 2009 and inflating rapidly) is more or less useless so they are willing to take the risk rather than starve or commit robberies.

People in western countries still have relatively stable currencies so gold, bitcoins and other stores of value have no wide appeal yet
(except in Greece which seems to be collapsing soon and might be expulsed from the Euro currency, people are hoarding silver & gold bullion)

I'd also imagine other states with failed currencies (like Zimbabwe with their 500 trillion dollar bills) could be interested in bitcoins regardless of legal status.
Not at a state level but among the part of the population with internet access

Very impressive, professional site. A few questions:

1. As mentioned above, will you add physical information about the exchange's whereabouts? Mt. Gox is known to operate from Cerulean Tower in Tokyo, but they do not list any address or phone number in public.

2. When (or, if at all) will you accept wire transfers as deposit and withdrawal method ($USD, Swiss franc, EUR, JPY)?

3. Do you have an automated system for instant withdrawals and deposits of bitcoins from/into the system via unique, 24 hour disposable wallets like Mt. Gox?

Cogent also spent extensive time on proving how he is legit and how he's not "rickrollin".

Turns out he scammed AmpEater out of the price of two 5850's that never arrived.

If I were AmpEater I'd arrange local pickup for these "two rigs with 5850's" and ask if he knows anything about his "friend".

Because you owe him "rick". And there is no "friend". It's just you under multiple aliases.


Then accept ClearCoin or local delivery/pickup.
Or even better, send the guy his 5850's he paid you for, without making excuses about how you know nothing about your "friend" who has suddenly disappeared from the face of Earth.

My apologies then. That explains everything.
(My 11th birthday is just coming up so I didn't expect any adults to be using Bitcoin,
I'm just mining to buy Lindens for a pet Pikachu in Second Life)

Cablesaurus' brand new PCI->PCI-e adapter comes without a Molex. It's just an extension board you install in a PCI slot.

Maybe you are thinking about the PCI-e x1 to PCI-e x16 adapters.


You can't use PCI-e x16 cards in normal PCI-e x1 slots without buying extender cables/adapters.
Unless you want to break the slots by sawing off the ends in which case the board loses it's warranty and resale value.

Yes you can.
My biggest rig is running a 6990, 5850 and a 5870 all at the same time (total of 4 gpus).

You don't need to crossfire anything & everything will be detected as long as you have enough monitor cables or dummy plugs.
