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.

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.

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.

I thought this was porn? What do you normally look at?? Grin

it is better than porn and is properly called 'Pr0n'.... there's a fine line between the two and it's tough to tell the difference sometimes but the properly spelled 'Pr0n' and always takes authority over standard 'porn' or 'porno'..... they are usually much easier to find on the net than this kind of stuff

This isnt quite true. Heat cycling is a small risk for haircracks in solder and underfill. This problem has become well known when a batch of nVidia cards suffered from a manufacturing deficiency that made them extremely vulnerable to this. These are the cards you can usually "fix"by reflowing them in an oven. This is something that pretty much never happens with AMD cards.

High temps otoh increase electromigration. Electro migration can be thought of as "internal wear" inside the chip. Its what over time leads to lower overclocks (if transistors in the critical path are affected) or instability and plain old dead cards. This is far more frequent, particularly with mining cards. Electromigration is a function of heat and the relationship is exponential.

Yep, and thanks for including the additional one-hole PSU bracket - I am getting read to build a "mini" version of the same frame with the same layout, but only 1 PSU, 2 cards, and a tiny little mini-atx mobo. Then I will have the 6-card granddaddy and the 2 card baby all set up and hashing at an estimated 3300 mhash/s and 1500 watts or so. Grin
