Don't feel bad for taking MadScientist75 at his word, once. From this point forward, you should double check all of his starting assumptions, all of his data, all of his calculations and all of his conclusions. Those of us that know MadScientist75, know to do this.

I think the person who mentioned standard deviation earlier in the thread was doing so as a slight to MadScientist75. It is a #btcguild inside joke that stems from this little gem:
Jul 26 20:40:25 <sonicrules1234>    Mad7Scientist: Are you using standard deviation anywhere in your equations?
Jul 26 20:40:43 <Mad7Scientist> sonicrules1234, what is standard deviation?

Hilarity follwed. You can grep the online logs for #btcguild if you want the whole conversation. 

Anyway, Eleutheria already put this thread to bed with actual math and actual data. So I don't get to have fun with it. 

When the coins at mybitcoin are exchanged for dollars or euros, the identity of whoever converted those coins will be known to the exchange. Until that time, the coins from mybitcoin are exactly where they have always been. There is simply no way (at the moment) for their rightful owners to access them.

Nice setup! I know what you mean about "this should only take a couple of hours..." 

Do the PSUs draw air in from the top? If so does the motherboard block air flow to them?

Did you find a single rivet strong enough to hold the aluminum angle stock together?

You are touching Bitcoin.

Are you really paying .40 $/kWh? Ouch.

The differences I see between EGold and Bitcoin.

There is no central operator with Bitcoin. All transactions are visible, so nobody needs to get a subpoena. They only need download the transaction blocks. Also, bitcoin makes no promise to exchange into any other currency. Bitcoins are only tokens or chips and have no intrinsic value or backing by fiat, they are only as valuable as the need for a secure transaction is.

Very disappointed. I thought this was going to be a human centipede thread with all the ass/mouth talk. 

In an open case with good spacing between the cards, lots of air flow around the cards, and mild ambient air temps I haven't noticed a large difference in card temps.

In a closed case, the open style cards are a trainwreck.

I would like to be white listed so I can talk about the theoretical maximums vs practical maximums of parallelizing SHA256 on AMD hardware.

Also, at least one response to a thread in the Mining hardware section is to be expected. 

I have > 5 posts and > 4 hours onine.

This is the wild wild west. Expect the unexpected!

Yeah, I am not sure I want to stay logged in for 4 hrs

4 hours is a long time!

Packing that many cards into a small case will always run hot. I doubt you can keep them cool enough to mine 24/7 without doing heat damage to at least one of the cards.

Get a really big fan and blow lots of air directly on/between them. Leave the case sides off.

Do they have to be useless? 

Uninstall and reinstall is the recommended method.

The probably is most likely with your drivers. I had a 2 core CPU maxed out at 100% just running 2 GPUs due to a bug in the catalyst drivers. Which OS and driver version are you running?

I have 11.6 Catalyst + Linux working with <10% CPU util.

11.7 Catalyst showed the same symptoms you see.

I think mining rigs are still viable. Unless Bitcoin goes the way of Esperanto...

Is there any duty/VAT to be paid from ordering in Canada from the USA(used to be AAA but now just A)?
