Also since this is a 12 card rig can you guys remind me again about the way the card order goes? I currently have all slots populated except the last 4 rows. So if you're looking at the miner management web page like this:
Bank 1 1: 35.204GH/s 2: 37.366GH/s 3: 35.176GH/s 4: 0GH/s Bank 2 5: 35.562GH/s 6: 32.599GH/s 7: 23.365GH/s 8: 0GH/s Bank 3 9: 33.315GH/s 10: 34.145GH/s 11: 26.829GH/s 12: 0GH/s Bank 4 13: 35.204GH/s 14: 38.612GH/s 15: 14.03GH/s 16: 0GH/s
The last 4 slots on each bank are empty.
I am assuming this is the correct logic to apply to spread out the cards across all bank as punin suggested, but if any of you know better please correct me.
You're doing fine, the only other thing to do is to have the slowest/most error prone card as last one in each bank, and from the numbers it seems it already is like this. Try to put all the cards/chips at the same speed, I've found it is more stable than having speed differences between cards. spiccioli Glad to hear I'm not doing anything stupidly wrong. As for getting all the cards/chips at the same speed you mean actual hashing rate or the clockrate in the miner's best.cnf file? I currently have those card overclocked a bit. I tried to get them as close as possible to 1.70 ohm on the R02 resistor. It's a pain in the ass to do and there is no precise method so this results in some cards being pushed harder than others. Now as far as clockrate in the miner's conf file I tried my best to have them running at the highest clockrate that is possible without the chips producing too many errors but this once again is a bit tricky. Sometimes the chips run fine at a particular frequency for a long time and produce low errors and after some time they crap their pants and start producing errors. Like I've been saying all along I find bitfury gear finicky and not as robust as it really should be. But that is just my opinion.

But that is just my opinion. yeah, its definitely not robust equipment. its a beautiful and elegant design, but its not remotely robust Ive actually got my fastest card as the 3rd/last slot in my first bank, since it was the original from the starter kit with biggest heatsinks that prevented it from going anything but last in a bank. its still doing 37-38GH while the rest run at 33-35GH

new price is still too high, but less insulting. drop it to 200 and you can actually start moving inventory
$200 is unnecessarily low. I'd pay 0.40 BTC per card if shipped today, which is currently $325. So if the exchange rate were to jump up to $935 in the next couple hours, I'd buy more v1.2 cards. I'm more conservative in my hardware purchases than alot of people, so they definitely don't need to reduce the price any lower than $325 to keep sales flowing. if you prefer to spend more money than make then yes. card running at 33ghs would not make its .4 btc back I run mine at up to 39GH/card. But I pay over $0.30/kwh for electricity so the current prices (in BTC) are a bit too high for me. how did you get so high at 39Gh/s? 39GH/s is the average of the cards in my most optimized v2 rig. I raised the voltage to about 0.85v when idle. I never got around to checking when hot. And I spent alot of time finding the best speed settings per chip without overloading the VRMs. When the weather warms like in the last few days here, some cards' VRMs cut out until I tune down the chip speeds just a bit, usually just 2 chips at a time until it's stable again.

I especially like their Disclaimer: 16 Bitfury ASIC chips (all chips are not guaranteed to work) Individually tested for 25 GH/s (performance may vary depending on board position in M-board and your settings)

It gets repetitive and monotonous after some time.

Nice. Yeah tell me about it, some of my cards have as many as 6 fracking dead chips!

It takes one night of fine tuning, you save your best.cnf file for both warm and cold temps and when its too warm you just rename a file and its back to stable. My new half rig runs at 310, half of what my full does so I am happy. It took me about an hour to get it to that point because I already knew the tricks. Now I just need to turn it off one more time so I can put some stabilizers in and it may run even higher  new price is still too high, but less insulting. drop it to 200 and you can actually start moving inventory

I bought 3 October units. I cancelled 2 of them, still no refund. The one I did receive gets 100-200gh and that's if I restart and mess with the settings constantly. I would think twice about trusting these guys, they could care less about customers so long as they get your money.
Let me know if you want to sell some or all of the rig you have. I'm pretty sure the problem is with the cards. Everything else has been replaced. That doesn't sound like MBP at all. Dave hired Jason to take care of customer support. Have you tried to contact him yet? I don't know them all by name. I emailed them back again Monday but I have not heard back yet.

BitFury 55nm is in the same league as most upcoming 28nm mining chips IMO.

I meant that 28nm products are going to be commonplace in the next few months. Most 28nm dies are huge, and thus board manufacturers sell them with factory heatsinks, watercooling, etc. I donot know if Bitfury has plans to roll out 28nm chips of their excellent product.

I thought bitfury has a better W/GH even over 28nm. Also aren't 28nm more expensive then 55nm?

Any price drops on the 400+ GH/s models or introduction of higher GH/s setups (basically an addon master card/board)?

I see they are selling them quite good and overpriced of course. When people are buying them is there any reason prices to be dropped? The answer is......

I still don't understand why people are paying for overpriced miners to fund bitfury's private farm (currently at 200TH). Remember people: for every miner sold, bitfury adds a couple more to his farm so think twice before ordering. Stupid stupid people.

And do you honestly think that Bitfury doesn't currently have enough funds to support it's own private farm without the few pennies that we add to their coffers? Lol. Who's stupid now?
