with only 1 H-board in place drawing 45W, can I only use 1x 6pin PCI-E power cable instead of 2 of them? if so. which one, left or right?
With a fast look to the layout i think it should be okay to use just one, no matter which one. Because the layout join this two power cable.

Ciao

Added:


4. How to fix an empty miner File?

NOTE

Due to my personal epic screw-up the SD image does not contain a working binary. And on top of this some orders were shipped without instructions also Tongue We have whipped ourselves vigorously here over the weekend and will try to improve our process so these bloopers don't happen in the future.

Here's how to get your miner working:
1. Check your router for bitfury IP
2. SSH into the raspberry pi (username pi password raspberry)
3. Run following commands:

Code:
cd /opt/bitfury/chainminer
sudo make clean
sudo make
sudo killall screen
sudo /etc/rc.local

You should now be mining. You can check the web interface of the miner with a normal browser and setup your pools there (use the IP that you used for SSH).

For people having hashrate drops - borrow PSU from friend and check.

In my case I had malfunctioning PSU (400W). It works perfectly in PC but it turn out connecting it to miner (2 H boards) I had strange fluctuations with hashrate. It didnt drop to 0 but instead went form ~50GH to ~10GH after some time. Again - that PSU works fine in PC. Finally Ive put another PSU - cheap 350W, 20$ chinese one and it runs perfectly - 58GH rock solid.

I think some PSU have some kind of regulator (whatever thingy...) and dont push full power. Or, they simply are a lazy bastards.

Interesting, this is definetley something I need to check out as I have been having some stability issues at ~500w pover drawn trough a 750W PSU.

Since I filled each slot in my miner I'm having also ... problems to maintain ... hashrate of each board over 30 GH ... I'm unsure if it's because of the heat ... or the heatsinks ... that are blocking airflow, ... a PSU issue? .... some how I've some boards that work on one slot better then on an other one ... does anyone has a good approach how to get ... the best postitions ... ^^

also I'm seeking good heatsinks ... for the regulator part the arctic cooling stuff is to big ... something around 5 mm ...

Seems a PSU problem ... as soon as I pull to random cards of the mboard ... I get all cards hashing well again ...

... Im using ...  Club 3D CSP-X1200CS, 1200 Watt, 80 Plus Silber



I'm unsure is this PSU limiting wattage on 2 PCiE ... to 2 x 255 Watt?

Looks like you have a multi rail Psu have you tried plugin one pcie connecter in from 2 diff pcie sets ?

Yes, you'll need to figure out which connectors are on which 12V rail. If you're using two pcie connectors from the same 12V rail then the total power will be limited to 480W (if the details from your PSU manufacturer about the different rails are to be believed). These PSU manufacturers are sneaky though, sometimes their rails are not configured in the way that they say! A good site to look at is http://www.jonnyguru.com/, but I don't think that your PSU has been reviewed there.

In my experience it's a big problem when more than 3 slots per bank are used and to have >30GH/s per board. I think it's a software issue. Any hints from the developers would be awesome. I have even tried soldering power cables form each H-board directly to the 12V connector, but no fish.

OK, so with 80A max on the two non-modular pcie cables this should power the miner with no problems at all. I guess the problem does lie elsewhere, as goxed mentions. Good luck finding the solution!

Part of the problem for me atlest is the undisputable fact that some of my boards require different cooling than others. The rev 1 boards do have problems starting up when too cool. Before someone goes a head and dismisses this as absurd or tries to refute my point: stick one rev 1 board in the freezer, untill it's at 0c and see if it starts mining at anything above 8Ghs. My current physical setup has the capability of feeding sub zero celcius air to the fans during nights... and getting cooler by the day. Sadly the sweet spot where everything works is not as big as I'd hope it to be.

I found some sweet 35x35x6mm heatsinks. 4 of them work great per board and leave room for airflow between slots.

as for 3 slots per bank, i beleive its related to the 30A limit of a texas instruments chip mentioned by intron a while back. Its got 10-14 pins and there is 1 per bank. Most likely it simply cannot handle more then 3 overclocked cards or 4 cards at 25GH

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe

I'd like report the contrary, this is my most stable bank:

Can you please post the log file of these chips? It would be helpful to mod the chainminer software.
Also what voltage are the cards at? Thanks

I dont/wont measure voltages, as it requires disassembly and has the accompanied risk of breaking stuff, I dont have very steady hands, sorry.
The resistances on R02F's vary between 1.67-1.62k Ohm.

Do you got all banks filled ? ...

How about the other banks ...

That is the only full bank I have, the remaining ones have 3-2 cards.
