Since when is playing the BTC market (or any market, for that matter) some guarantee of this amazing profit you folks keep bragging about?  For every winner who buys low and sells high, there's some poor sucker who bought high and sold low.  And this whole 'buy and hold' thing... who actually does that?  Really?!  Every Schmo thinks they're are smarter than the next guy and they know exactly when to buy & sell and to hold.  And in reality, they are usually WRONG 50% of the time.

This argument is so very OLD & TIRED.  Why no take your unsolicited advice and 'sure-fire' investment theories and go right over to the Speculation subforum?  Seriously, no one here wants to hear it anymore.  This is the 'Custom hardware' forum and no one cares what you think.

My estimation is that you can make about 4.6 BTC extra with one upgrade, so almost 2 BTC profit, assuming your upgrade starts hashing at the beginning of next difficulty adjustment.

The fact that BTC is at an historic high price makes this deal very attractive—because the price of the upgrade in BTC is low—so it is a good deal if you plan to reinvest BTC you already mined.

You should compare this to the price AVALON is currently selling it's four module miner 5.5 BTC for 110 GH/s at 750 W (twice as expensive for less hashrate and around 4 times the power consumption)

I tried today.. had one too but the page just loops and never puts it into cart's next page

I agree with Mark there is a memory leak somewhere, on some machines at least.

I've had the best luck with running cgminer 3.7.2 manually after killing the one that comes with the knc firmware, but even then after 3 days free memory has dropped 100MB, from 250MB down to 150MB free, I haven't had it drop so low that it stops mining like Mark has, but I've seen it drop down to the 12MB free mark before I rebooted.

BTW, if someone wants to sell me BTC at mtgox price via paypal, pm me.

they canceled my order from Thursday last week without any information to me. it was wire transfer!

ohh man, will these ASIC producers never learn what customer/investors makes happy?

they are rich now, right? and where came the money from?

Our second wave of shipment has sold out faster than we expected. We had aimed to sell from stock. However, due to the recent BTC price activity we sold.

Heatsink, no, it's readily available, and not worth the shipping cost to you to have it globally couriered from Stockholm to country X. It's a heavy thing to ship for something that's approx £30 online.

Cables, PCI-E extension leads, screws, and that blank aluminium pieces that affixes the heatsink to the board, ya.

So what heatsinks can we use?
