The only place we might be seen to be at fault in my view is finishing our bitstream and not getting the Icarus replication quite perfect. The bitstream is a couple of weeks behind schedule but does have great promise.
All I can say is that we sold this product as a concept going into a development program and it is exactly that. I don't think we could have been clearer on that to potential customers ...
I think you could have been a bit clearer on this. I may have been a bit rash in buying this, but it was described as a board 'specifically for Bitcoin' - and I guess it wasn't in my expectations that I'd need to closely follow a 68+ page thread on the forum to know the state of things. Perhaps because I have only been checking a couple of times a week - I'm still not clear about what the board is currently capable of nor how to achieve it.
Currently I'm running mine stock at around 100MH because the processes for eeking out a bit more looked pretty problematic, and nowhere near the target 800MH yet anyway as far as I could see.
As it stands I don't know if I'm supposed to be monitoring the page at http://www.enterpoint.co.uk/cairnsmore/cairnsmore1.html
, this thread, or some other thread for a completely 3rd party bitstream solution (??)
The very first post of this thread has this and I don't think this has been materially changed since the thread started..
We have listened to your comments on Merrick6 (see other thread) and are going to create a board specifically for Bitcoin with 4 XC6SLX150-2FGGG484C FPGAs. The price guaranteed until the end of June 2012 is GBP £400 / USD 640 / 520 Euros (plus tax and shipping). We are selling at the cost to manufacture price until we do the work of benchmarking it and check it working with the Bitcoin interface software. After we complete the benchmarking/software work the price will increase by 50% to cover our costs in doing this work and general support.
To get the initial price we need to receive an order before the end of June. You price and order will be confirmed to you by email. We may extend this offer at our sole discretion. Payment will be by PayPal or by bank transfer.
Prices are based on current exchange rates or staying within 5% of current rates.
We will accept pre-orders on the basis that no money will be charged until your board is ready to ship. We reserve the right not to sell to any person or organisation and/or to ask for more information in respect of and for export control. To pre order send an email to bitcoin AT enterpoint DOT co DOT uk with address and contact details.
UK shipping cost is £8 + VAT. EEC 32€ + VAT, US $40. Please ask for other places.
Local duties and any applying taxes will be charged direct to you by courier. For UK and EEC we will charge UK VAT unless you are VAT registered in your country (not UK).
We expect to complete the design for this board by the 1st of May 2012. We will show some CAD images of the board then. First production boards will ship towards the end of May although some lucky people may get them earlier. I will announce image availability on this forum.
The spec of the board is as follows:
FPGA - 4 x XC6SLX150-2FGG484C
Heatsinks - stick on or clip on supplied with single 12cm fan(with mount pillars) to blow over all
Size - approximately 15cm x 15cm.
Programming - with our Prog3 cable (£50/$80/65€) or similar. We may add this interface into board as standard.
Data transfer - FT4232 USB interface. Each FPGA has a port.
PCB - 4-8 layer
Power input - 12V from Jack or disk drive (Molex)
SPI Flash - We will have local FPGA image storage so you don't need to JTAG load every time.
Clock - single oscillator or clock generator.
Core voltage - 4 regulators each 12A
There is no performance specification on the Cairnsmore1 website pages as far as I remember or every has been and all we have talked about in terms of performance that we expect to attain is somewhere in this thread.
As to your specific performance issues have you sent an email to Enterpoint outlining the problem. If we have missed that I do apologise and do send it again to us. We can't fix what we don't know about. You might have a hardware fault or there might be something else causing you an issue so tell us about it. We are slowly working our way through support items as best we can and we will take action based on a custom need.
There is something about 700-800 MH/s and the price switch somewhere in this thread. I probably said also at our discretion. I'll struggle to find that now and by all means do quote what I actually said. But it's a fact that it is our choice what we sell a product at and when we change prices. It's not like we didn't warn that there would be a price change. That was said on day1 in the first post.
