And I tryed a Cloud http://www.cloud.hu/hu too It need at home a very little place And no risks And scalable

You're all doing it wrong. 

I kid, I kid.  I've actually taken down my 3.8GH/s setup and sold off most of my parts, after which I built:






But of course it wouldn't be worthwhile without the sexy lights:




This is definitely a game-centric rig:

3x XFX 6950 @ 845/1325
Phenom II 1090T 6-core @ 3.9ghz
Gigabyte 990FXA-UD5
8GB DDR3-1600
2x 120gb SSD in raid-0 (1GB/s!)

I don't do much mining with it, but it'll get ~1.1GH/s all spun up.  At < 40dB.  At < 50C. 

[fizzisist]

Here it is, 16 x X6500 FPGA Miners for theoretically 4.2 GH/s. With rejects, it looks more like 3.8 GH/s. 258 W measured at the wall.




This whole system is quiet. I have 4 120 mm fans cooling the whole thing. They're all running at full speed, but could probably even be slowed down a bit.

[cicada]

That is pretty frakkin' sweet.

Have you had any issues with the OS addressing that many USB devices?  It looks like you've got a fairly good hub which probably presents itself as such to the OS, I've had some crappier hubs that start to complain when you multiplex >4 devices..

[pazor]

hello,

become fpga mining reallity?
tell us your  experience with this type of mining please !

...and you spend a lot of money for your equipment...

Thanks, and no the OS seems to handle it fine. The worst I've seen is that the bus is a bit bogged down, but that could probably be fixed by polling the FPGAs for nonces a little less often.

Yes! This system is built using the boards that we (fpgamining.com) designed, produced, and are currently selling. https://bitcointalk.org/index.php?topic=40058.0

An honest review of this type of system should probably be written by someone other than me, since I'm far from impartial. Hopefully some of our customers will write about their experiences. I'll also try to write up some of the things I learned, so that others can learn from my mistakes.

The price is $580 per board at single quantity. There are bulk pricing discounts, though, which you can find in that thread.

Can you please tell me how much do you estimate this setup cost you?
It's quite magnificient and quite a job!

  And yes, very sexy. =)  eventually I will get around to posting some pics of the few cards I housed in Capri Sun boxes.

Cost for you to build this system today:

16 X6500s at $550 each: $8800
Power supply (I used this one): $65
4 120 mm fans at $15 each: $60
Various Molex splitters and adapters: $20
16 USB cables: $50
USB hubs: $30

Total: $9025 / 4.2 GH/s or 2.12 $/MH

A lot of those extra things you probably have sitting around already, or you could find better deals.

The next price break above that is at 25 units. You could still run that many boards off of a single supply (400W) so your overhead cost would only be slightly higher.

25 X6500s at $535 each: $13,375
Power supply: $65
Fans: $90
Various Molex splitters and adapters: $30
25 USB cables: $75
USB hubs: $40

Total: $13,675 / 6.6 GH/s or 2.05 $/MH

You will also need a host computer to run the system, but you most likely already have that and the performance requirements on that computer are quite low.

Note that those $/MH are based on 266 MH/s for each X6500. I have every reason to believe that we will reach higher hashrates with improvements to the software and firmware in the future.

Great, I love you to start out FPGA clusters, there is only one possible criticism, it is wasteful to use a USB cable when two cables are only useful around the connector, I mean the input and output data, it may reduce the cost with the use of two simple normal pins and wires between the PCB and the hub.

Off the shelf is usually cheaper than custom.

If you create a custom wiring interface then you need a custom built hub.  It is unlikely to be cheaper than a usb hub and usb cables.  A 12 port hub is <$2.00 per port and usb cables in bulk are less <$1 ea.  So cost becomes <$3.00 per unit (likely <$2.00 if you look hard enough).  Maybe it is wasteful/overkill but it is unlikely any custom solution no matter how spartan will be cheaper than $3.00 per unit.  Even if it is you are splitting pennies when you look at total system cost.

This seems like a work in progress, is that card in mid-air secure ?

Tip: You only needed one resistance for dummy plug and btw they are not needed anymore. (with updated drivers)
Tip2: Try raising your 5830 to 960-975 mhz

Yes, it's secure, it won't fall down unless an earthquake occurs.

Thanks for the tip about resistance, but if don't use dummy plug then I can't set frequencies with afterburner, I'm running 11.11 version driver.

5830 @950MHz reaches 300 MH/s, but GPU Temp#2 will be 73~74ºC, not 68~69ºC like now which is confortable for me.

To improve efficiency you should raise your clock as much as a given voltage allow.

Below 85c there is nothing to worry about long term.

[Turbor]

Below 85c there is nothing to worry about long term.

Hmmm for me it's more like below 70C and 50% fanspeed. But to each his own.

Temperature variation is the real card killer.   I'd agree with anything < 80-85C, but some cards just don't stay that cool even standing alone with good ventilation and room-temperature ambient environments.

It's more important to make sure your temperatures aren't swaying significantly on a regular basis, the (small) expansion/contraction will eventually stress the metals in your GPU, leading to reduced life.

A stable 80C is far better than swinging between 60C and 80C every day.
