pumping it claiming BTC going to $10k-$100k, now claiming $200k!

His message is going out on RT and reaching 550 million eyeballs in 100 countries.  

Previously he was pumping "$500 silver if you want it" but it only got to $50.

Now somebody just needs to make it easy to use.

Bitcoin needs to be a phone app so simple even your parents could use it.  

You miss the point of bitcoin, it's goal is to replace national currencies, even if there were no exchanges, only Wall Street speculators would care.

Avalon is the only game in town right now.

Butterfly Labs is a maybe. It will be the more efficient product, if they can get it to work.

I don't see how they could drag this out another month without delivering something, a prototype to a reviewer at least.  

It's probably just waiting for the pool to send it some work.

They wouldn't use hashing power anyway, they would just attack the exchange rate, using the Exchange Stabilization Fund.
$105bn vs. 0.5bn

Reward halving ensures BTC prices will always go up. 

I suspect the bASIC funds went on buying something like this.
Not many people understand pre-order arbitrage scam = free equipment loan.
Try to refund in devalued dollars, and if they insist on BTC, you'll mine them in some time.  

2x 7850 is cheaper than a 7970 for the same 2048 of stream processors.
Crossfire dissabled I'm getting
Stock 2x860MHz = 500Mh/s @ 160watts
or
Overclock 2x1100MHz = 630Mh/s @ 200watts

A bitcoin price above your hardware and electricity running costs! http://www.bitcoinx.com/profit/

You won't be able to earn a living on transaction fees if your mining pool steals keeps them. Always ask your pool what happens to transaction fees. Eligius

There will likely always been another crypto-coin to mine when Bitcoin gets unprofitable, if your ASIC works with it, that's another story.

Some cards have cheap fans and heatsinks that are not suited to mining/overclocking.

I don't recommend cards with ring coolers as they don't have a large surface area.

It could just be driver related. Try a different catalyst version. I like 12.11beta.

At 81c I'd expect the fan to be higher than 62%. 90c+ is where EU lead free solder starts to get brittle.

NASA did some solder testing for Mars rovers from -120c to 85c and managed to break the solder in as little as 638 thermal cycles.  

Yes just report him to ebay for asking for payment outside of PayPal it's against their terms of use to refuse to accept it.

81c is pretty hot. Bitcoin probably runs hotter than your benchmark.

Make sure there is no dust in the heatsink.

You can turn the memory clock down to save a bit of heat.

I always recommend 5830s rather than 6770/5770 they run much cooler and faster for the same price.

Did you try reading this thread?

[FIXED] Avalon URGENT ISSUE: both of my avalon do not work any more

Makes no difference run what you want when they are not crossfired and using it for mining.

You can use LinuxCoin it's all been setup for you and it's small enough to run from a memory stick.

If you're gaming they have to be the same series and crossfired.

If not crossfired you game on the first card and the others can mine in the background without causing any lag.

Yes the coin will appear once you download all the block chain (takes days)

If you don't want the hassle of keeping an updating block chain choose a lite client wallet.

Technically you're supposed to use something with 6 x 6pin PCI-E Power

But you can get away with a cheaper 4 x 6pin PCI-E Power model and use a couple molex to PCI-E adapters

The video didn't show how they get the balls back on though, they just have a little pot of solder balls and roll them on.
Anyone who has this done should ask for the best grade solder balls with a higher melt point.
(you don't want more of that EU lead free rubbish that goes brittle after 90c)
