Watercooling the world of mining

Hello,
to add some math to this disscussion i would like to advertise my new

"Bitcoin mine or invest spreadsheet & mining rig comparison spreadsheet"
https://bitcointalk.org/index.php?topic=56475.new#new

Please use it to find your very own answer about how your minig rig will perform.

I hope it is helpfull to you all

Looking forward to the new firmware.

Also, your continued support of the previous board (X5000 - only very few boards made) should give any potential customers confidence.

I tested the software against ABCPool and it appears that it's replying with no data to most of the long-poll requests. I have no idea why that is. Does anyone happen to know if ABCPool does something quirky there? I'll do some more debugging...

Thanks for reporting the stales you guys have seen. I'm really not sure why they're so high. Definitely need to do some more work here. For what it's worth, Eligius usually reports between 4 and 6 % rejects, and a number of those are supposedly duplicates, so I'm not exactly sure what that means or how that could be happening.

In other news, we're testing out new firmware! fpgaminer was able to incorporate some of ztex's open source HDL and it's now running at 175 MHz (350 MH/s for the X6500). We need to do a little more testing and update the copyright notices and we'll release it to all of you. Sorry to make you wait!

350MH? pretty nifty.

243.94 MH/s | 0: 9305/772/0 7.7% | 1: 9282/836/0 8.3% | 4d2h45m

before the LP support i had around 10% stale, now i hab 8%, also V0.11 is stable for me

Okay, I was getting like 10 even after LP at ABCPool, and I am getting like 6% at BTCGuild now.

looks good at slush's pool

I always get 'Long-poll: Value error!' followed shortly by a long poll connection string.

It seems to be working though (no stales or anything).

This is at ABCPool.co

Actually, stales are actually pretty high still. What are other people getting for stale rates.

I can try another pool for now!

Very strange... I'll run one against ABCPool myself and see if I can figure out why that is.

The other two available fpga bitcoin boards have an open design - I can reuse them for different purpose, re-program or sale them as fpga dev kits if I decide to stop mining with them.
I would at least like to generate my own bitstream with your board, will this be possible? Will you release the schematic?

Yes, you can certainly try your hand at developing a new bitstream, or develop different applications for the board. You just need to tell ISE the part and the clock pin. It's the Spartan 6 LX150, -3 speed grade, FG484 package. The clock pin is K20 and 2.5V. All communication including bitstream loading is done over JTAG, and handled by the FT232R over USB. If you want to bypass the FT232R, the JTAG pins for each FPGA are broken out to a pin header and labeled on the board. I think I'll write all this up in a separate document and post it on the website. Let me know if you think any other info would be helpful!

The board is now mining for some hours at Bitcoins.lc pool.

It mines at 250mh/s and gets some few RPC upload errors.

My earlier error was i got the wrong phyton version.

@fizzisist:

Maybe for windows users the complete executable for 2.6.7 might be handy
to be found at http://www.activestate.com/activepython/downloads

That's great! Sorry, I hadn't noticed that the python site only has the source for 2.6.7. It makes much more sense to link to a compiled version, either your link or 2.6.6. I'll update the guide.

By the way, another user and I finally solved a problem he was having with x6500-miner on Linux. It turns out that FTDI put out a new Linux version of the D2XX drivers which is incompatible with my hacked PyUSB solution. If you installed libftd2xx version 1.1.0 and having problems, please download v1.0.4 from the Software guide.

Err, it looks like those are shipping from Hong Kong though. Can someone recommend a good AC adapter that ships from inside the US?

EDIT: Ended up ordering one of these: http://www.ebay.com/itm/270728205788?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Looks like a good find for the price. The only problem I can see is that the current output is almost cutting it close. 18W is not a lot of margin over the 16W I've been seeing during testing. I would just keep an eye on it to see if it's getting really hot or something (the wall wart, that is).

In other news, I now have a crude implementation of long-polling in the latest version on Github. So far it seems to be working, but I really need more testers, especially on different pools. Please try it out!

Just ordered one of the X6500 boards. Looking to grab a barrel connector to power it. Will one of these work: http://www.ebay.com/itm/AC-100V-240V-Converter-Adapter-DC-12V-1-5A-Power-Supply-/320749488518?pt=LH_DefaultDomain_0&hash=item4aae28c986 ?

My focus this week will be to get to higher hashrates and implement long-polling, but please everyone let me know if you come across any more bugs or have any ideas for new features. Thanks!

I think absolutely everyone will agree that long-polling would be the most important feature you could implement!

Any word on the barrel connectors you said Cablesaurus might be getting soon?

I received one and tested it out this weekend, and it gets my stamp of approval. Cablesaurus should have them in stock soon. I'll see if I can get an ETA.

Do you have the D2xx drivers and the right version of pyusb installed for your version of python?

Watercooling the world of mining

Hello

I just got my board an am trying to get it to work on windows 7.
I installed the software parts according to the guide.

But wenn i try to run the program.py i get the following error:

Code:

C:\Users\O_Shovah\Desktop\FPGA_x6500\fizzisist_x6500_miner>program.py C:\Users\O
_Shovah\Desktop\FPGA_x6500\Bitstreams\fpgaminer_50mhz.bit
Traceback (most recent call last):
  File "C:\Users\O_Shovah\Desktop\FPGA_x6500\fizzisist_x6500_miner\program.py",

ine 22, in 
    import d2xx
ImportError: No module named d2xx

It seems there's a problem with the FTDI driver but it should have installed correctly.

Any ideas where i went wrong ?
