Yay got my 20 Lancelots! In 6 boxes! Took over 2 hours to unbox and assemble.

PROBLEM: Blackarrow, your pci-e ports are wrong! I can only get 6 pins in, not 8! You seem to have used EPS sockets. What is the remedy? Will there be shorts or problems with only 6 pins or were you expecting EPS and I will get shorts? I paid extra for a PSU with 2 8 pin pci-e and this is frustrating.

Yay finally assembled and wired up!

PROBLEM: After plugging in 15 lancelots, any more and windows will say usb device unrecognized and the hub shuts the port down. It's not the boards because when I switch them out, they work if I stay below 15 boards. I don't think it's a Windows problem because even the hub refuses it.

Help! Cgminer, ever heard of this? I'm using 2x10 port hubs, uplinked to 1x7 port hub uplinked to one usb port on the computer.

Great pics Bitpop.

I wouldn't have thought you would need to plug your PSU into every connector on the adaptor board.

Your using Windows on that old IBM of yours?  3.11?

Try Linux. cgminor on a USB stick.

[bitpop]

Yeah trying to pull 600 watts off only one connectors will melt it. You have to use them all.

I don't want to use linux :/ I have a windows server 2012 that I use for everything.

Where did you get that thing?
Is that still available?
What wattage does it handle?

My power break out box from Black Arrow had a 24 pin ATX connector on it. I used that one and only that one. Working fine for me.

So, all 3 of them contributed to both projects

Somewhat incorrect.

Apologies, didnt know the full history.

From blackarrow. 600 watts to 20 lancelots.

Damn I spent a lot of time and money finding my PSU with all the right plugs.

CGminer: How can I use more than 15 devices?
How do I increase the window size? I can only see 14, hoping there's one more but the window won't resize.

I don't know if your joking or not but yours has it too and your ATX power supply has that same connector.

The limitation is in the windows dos box, not cgminer. Open a command prompt window without anything running in it. If you right click on the top of the command prompt window you should find something like settings, and you can change the window size to include more lines every time you open it.

Alternatively you can start cgminer in the --compact form which will fit any number of devices but only give you the summary, not the details of every device running. A small text display was never designed with so many lines in mind

[bitpop]

No I was serious. Took a while to find a psu with 2 8 pin pcie and turns out the splitter has it wrong.

Thanks. I ended up adding a second computer anyway due to usb problems. 128 device limit is bs. Mine couldn't handle 20. Or these serial chips suck. Wonder if prolific has the same issues. Ftdi Has always been a Bitch.

Get yourself a raspberry pi. Cheaper than running another PC.

[bitpop]

True, I had a pi, unfortunately hated it and tossed it.

Install cygwin and run cgminer in its terminal program, which has a properly resizable window.

Cygwin is standard equipment on all of my Windows instances.

Okay, been mining for about 30 mins now, with power from the PSU and going strong, updated my earlier posts too as It was my fault that I didn't notice the not working green light on the power brick

Use  --icarus-timing short for 400Mhash performance.

Thanks mining away perfectly ! and sending out about 5 diff1 shares per minute

Thanks!

The connectors that we've used are not PCI-E because we couldn't find PCI-E as we've wrote everybody who've ordered ATX converters. We've delayed few orders for 3-4 days because we're waiting for the right connectors from the factory. We got the wrong connectors from the factory but we've discovered that you are actually able to fit the PCI-E connectors in these ones and they work without problems, so we've shipped them this way.

If you want the right connectors at the moment we need to place an order for 25000 pcs. Would you be willing to purchase this amount of connectors? :-)

Quick solution: just plug the PCI-E in using more force.

P.S: Imgur.com is blocked in China, I cannot see your pictures.

I disagree. On our testbench we've been testing 50 Lancelots on a Linux computer at the same time.

Now we've got 12v 62Amps power supplies (will post them for sale too) and we're planning to up  this number to 100 lancelots or more.
