Yes, but you could using these have more than 5x7970 on single rig

But mostly they are just curiosities

Those coolers somehow looks epic on that board! *thumbs up*

Nice results

So USB3.0 device to connect 2x PCI-E devices?
On another thread there was just talk about this, i thought i had seen something like this but thinking it had to be a joke or something ...

Anyone know who has these actually on sale and at a price?

Slush luck: 78%, 112%, 101%
1day, 7day, 30day
but it's been a really bouncy couple days.

Most i hate about Cisco switches is that every single model has somewhat different management commands/configuration ffs! :/

Indeed, and they told me that any orders done in March would receive that version.

oh ffs, any forced TX fee will be top the detriment of BTC. Let the market decide!
Market forces are incredibly strong, you guys are not giving it enoug credit.

Forced fee of 0.01BTC today would be 5$ cents, ok that's not much for MOST of us, but how about africans? Indians? In Africa 36.2% of people live with under 1$ a day! GDP per capita is just 1200$ while in US it is 48147$, so that 0.01BTC works about 40 times higher for africans relative to their income, now would you pay 2$ per transaction? (Adjusted by living standards would probably be more like 5$)
Whoops, you just closed down 922 million people market from BTC by introducing TX fees! :O

TX fees will happen, no matter what, when block rewards go down, and more people see value in BTC. Bitcoin is still very small and niche. How many Bitcoin users are there currently? Not that many!
Market cap for all BTC too is very low still.

People will start paying TX fees overtime, introducing now any rules to stop 0 tx blocks, forced TX fees etc. would hinder bitcoin, maybe even to the point it never becomes widely adopted *oops*

The protocol is not broken, there is nothing to fix, 0 TX blocks are not an exploit or an attack.
Want TX Fees? By all means increase the required TX for Your blocks.

Eventually ppl will start including more TX fees. Last 24hrs was 6730 transactions which is extremely low when thinking globally. Now when we start reaching 100k transactions a day, which is still very low, if 0.1% includes a TX fee of 0.01, that is 1BTC a day - still very small by any standard. When we are close to having all 21million BTC in circulation, and active userbase of 100million, we are talking about something like 50million+ transactions a month. At this time even if just 25% miners adopt a minimum of 0.001BTC fee, people will be incentivized to gve TX fees, say 2% choose to include them at the minimum level that is 1000BTC a month already, still for smaller user base than PP has!

Average PP account has about 40$ on it, so at this point BTC has to be *at least* 19.04$ each (see my post in economics), but as BTC people tend to hoard them as investment etc. and no sane person keeps much money in PP, we can safely quadruple this to 160$, meaning each BTC is atleast 80$ worth -> 80k $ worth of TX fees a month with still very small adoption!
And to be honest, i see more like people having BIG balances as their savings etc. So we could probably increase that still *10 fold*.

If Bitcoin becomes a true success, to which there is currently no objections, we are going to see more like an user base of *2 billion*.
With same ratios of 2 transaction every other day per active user average, with 2% paying TX fees of 0.001BTC, that all of sudden becomes: 20 000BTC or 3 200 000$ a month in TX fees. More than 100k $ a day, more than 4k $ an hour, something like 700$ per block!

And you want to be greedy now, and slow that day from happening? (Greedyness is one of the biggest reasons new and inexperienced companies fail, hell, even i have fallen to that bear trap with a very popular site making hundreds of revenue daily!)

FYI, transaction fees has to be voluntary and arbitrary, so we can allow people a way to transfer cheaply very low quantities also (there is currently some forced fee for very tiny transactions tho, isn't it there?) for micropayments etc. other things which cannot be done with today's money gateways.

Think about a situation where BTC replaces Paypal ... And that is just the beginning!
TX Fees will happen, people will see value in that, especially if the benefits of including TX fees are heavily advertised by miners: Be included faster, support the strength of the cluster etc.

Yeah but in question was USB to PCI-E
notice how that netstor product looks a bit like BFL Rig Box? XD

ehrm... don't tell this anyone but .... Bitcoin mining is bruteforcing it! *looks shadily around hoping no one heard that*

XD

there might be, i saw some article for external vidcards for laptops once ... Seemed vaporware tho. or maybe 1st of April joke.

It's easier to sort with just devices, but yeah, it could be marketed as such.
Those terms are created so that we can still reap the important reward -> upfront ROI on the HW.
Dropping setup fees would mean that we are essentially donating money
In any case, 75€ is not much!

That is some BAD electrical rate :O

+75€ if you want to pay monthly.

Exactly, i will keep them mining if there is no takers, so opportunity cost is very low.

I also get the 7970s substantially cheaper than say NewEgg listing price, that helps too

515.4€ = 670.02$ so it's barely above the GPU price for the 1st year. I fail to see how that is NOT a good deal for someone short in capital?

Well, i bited and purchased my first 2 units.
Money reserved for next 5 after these arrive.

and i still got 7 new GPUs to setup too :/

From european individuals i have to charge 23% VAT
How much are you paying for electricity?

I was also thinking for serious miners a faster way to grow, as there is no serious upfront costs, just the operational.
For me the benefit would be from economies of scale and long term prospects.
That way you could get additional 6Ghash/s today instead of just 1Ghash/s for the same money paid today, as an example.

The 7970 1st year costs on this should be less than the GPU + Electricity cost even for most US based miners.

We shall see, a lot of this i have to setup in any case, and when it's all setup there might be interest all of sudden, and definitively would consider mainstreamers would be interested, those without know how or willingness to setup their own GPU farms, and those which just want to support Bitcoin and enjoy some profit at the go.

See if you pay 75€ setup + 43€ for the GPU to be brought online today for ~600Mhash/s, instead of paying ~450€ just to get the GPU, you can purchase full 2Ghash/s from me to have online TODAY. That equals the cost of SINGLE GPU. It leaves me to finance the remainder 3 GPUs + node + supportive/overhead hardware. Platinum cert PSUs are *NOT* cheap.

The difference is: 70$ or 280$ revenue on the first month.

First year 4xGPU Setup: 2060€ fees collected by me.
Cost of 4xGPU + PSU + Mobo + CPU + RAM @ Newegg is roughly: 1963€ excluding PCI-E risers, Fans, power cabling, electricity costs, space costs, CPU heatsink.
At 0.06$/kWh, if that system consumes 750W: 302€ for the year, combining for 2263€ costs for you (Plus what 100€ for the other HW, plus space?), meaning for 1st year you STILL get ahead.

sub'd

This is indeed rather curious. I guess no ne has more info about the mystery miner ...
Let's just hope if it's some über powerful ASIC rest of us will gain access to it as well.

GPUs still buy more Mhash / $/€/BTC, while having lower efficiency.
I see GPUs being ran side by side with FPGAs, those who have low electricity rates can operate GPUs quite profitably, while those with high priced electricity will opt for FPGAs.

ASICs however is going to be an killer application, a game changer most likely.

oh X)
Just thought variance would be smaller, but i guess not!

Same effect happens when you simply can pay off your electricity bills regularly without selling any BTC.
It's nothing special, just a matter of financial effectiveness.

During the turn from 14th to 15th there was 56minute gap in new blocks.
Only reason i noticed was because i was waiting for some transactions to go through.

Does this happen often, i thought it shouldn't? What are the odds of that just happening by chance ... Probably just chance but i would think odds of 1hr with only 1 block mined has quite low odds.

Who said i don't do both?
On another one of my locations electricity is billed annually ...
So if i don't mine today when rates are at $1, but when electricity bill comes and BTC is worth 10$ ... oops
Assuming i actually need to sell BTC to pay that.

Electricity bill always arrives at least month later, so if i mined at 5$ then stop when it's at $1 and then sell BTC to cover electricity while i were mining at 5$ ... ooops!

Only thing what matters is value at sale time - not anything else, absolute nothing else.
If i stop mining while value is low, it's equivalently more time to put off the ROI, 1:1 relation.
Some of us can afford not to dance at the edge of cash flow right now, in order to maximize gain.

Infact, i've yet to sell a single BTC of my mining profits. I used BTC to purchase some of my rigs last summer tho, when BTC was at all time high.

But, oh please, oh please, DO by all means shutdown your rigs down when value visits a little bit lower
