Title: CM1 Quad Spartan-6 FPGAs reserve 3 BTC
Post by: Entropy-uc on March 26, 2013, 05:16:42 PM
I have 6 Cairnsmore boards that hash, but not up to standard.

Two of the boards kick out 50% hardware errors, resulting in an effective hashrate of ~400 MH/s
3 boards have one pair operating below standard for hash rates ~600 MH/s
1 board was programmed with 170 MH/s bitstreams, so it is running at ~680 MH/s

All of these are less than one year old, so the Enterpoint warranty should apply.  I don't have the time to chase returns so I haven't pursued that option.  It is also possible that re-programming the boards with HashVoodo, or Makomk's faster bitstreams with give you substantially better results.  I haven't had the time to try.

All boards are up for Auction sale.  When the auction closes I will ship the boards from best to worst in order of the highest bids.





Terms of Sale
Payment in BTC only
Escrow with John K.
Orders of 2 or more will ship stacked for side cooling and include up/down cables
Buyer pays shipping 0.3 BTC within USA, cost plus 0.1 BTC international
Auction Closes Sunday at 12 PM Eastern time Escrow payment due within 24 hours, shipping will be ASAP from confirmation of escrow payment

Is shipping a flat 0.3BTC for any number of boards?

is the reserve 3btc for all the boards?

Shipping is flat for any number of boards.

The reserve price is 3 BTC.

Escrow fees should be paid by the buyer.  I recommend 0.1 BTC / board

Do some of them stop hashing and then do you have to manually restart them (unplugging power and/or USB)? How often?

the bids are per board, so you have been out bid long ago.

The CM1s have very sensitive on USB.  By discarding USB cables on any boards that drop out, and using good, powered USB hubs, I have reduced the drop out incidents to ~1-2x per week on the 140 odd boards that I have.

I will ship these units with the known good USB cables they are running on now.

Thanks.

Sorry about that.... everyone in this thread has bid for all so far...wasn't clear if the reserve price was per board.... makes more sense though :)

Whats the power usage of such board. I searched but didnt find the numbers not even on distributor website. Or i dont understand their tech language.

Can i bid on the fastest hasher only too?


Title: Re: CM1 Quad Spartan-6 FPGAs reserve 3 BTC
Post by: kinder112 on March 30, 2013, 08:34:39 PM
It should be 40W per board not sure if the low hash rate means lower power consumption but anyways this is nothing compared to gpu rig. I you want to bid for fastest you need to offer highest bid per board since they will be sold in highest bid gets highest hash rate fashion.


Title: Re: CM1 Quad Spartan-6 FPGAs reserve 3 BTC
Post by: SebastianJu on March 30, 2013, 08:54:57 PM
Thanks for the answer. 40watt doesnt sound bad. I wonder is this really for the quad-version? I mean these are 4 fpgas in one right?

How can such transaction be made securely? I worked with john as an escrow together already but when will he release the btc? Is it when the buyer has the fpgas in his hands? That would mean a risk to the seller because the buyer could claim he didnt get it or something. So how will this work securely for both sides?

I ship with tracking.

45 W is my typical result.

The highest bidder gets the best board, and I work my way down the chain from there.  18 hours left.

Will the buyer of the 2 broken fpgas get the bill so that he can contact enterpoint to get a replacement? Will it be possible for a new owner anyway?

I am interested - but is there a guide for step by step setup ? If yes, I will place a bid.

You would have to talk with Enterpoint about that.  The serial numbers will make it 100% certain to them where the boards came from.

Yes, I have been sending out a guide to getting started.

I bought all 6 boards, other bidder resigned.

I fixed boards by flashing them with HashVoodoo bitstream.
My results so far:
4 boards running 827, 835, 840, 840 MH/s (that's because bfgminer limit 210 MHz per chip, I will increase it later with cgminer)
1 board running 622 MH/s - 202MHz, 210 MHz, 210 MHz, OFF (one FPGA chip is dead)
1 board running 620 MH/s - 200MHz, 210 MHz, 210 MHz, OFF (one FPGA chip is dead)

Entropy-uc estimated it as:
Quote
Two of the boards kick out 50% hardware errors, resulting in an effective hashrate of ~400 MH/s
3 boards have one pair operating below standard for hash rates ~600 MH/s
1 board was programmed with 170 MH/s bitstreams, so it is running at ~680 MH/s
That's 400+400+600+600+600+680 = ~3280
I already have ~4564 (no less than that).

I am very happy with the results. Thank you again Entropy-uc! :)

I am very glad for you that this worked out so well!  It's fascinating that the boards work so much better with HashVoodoo.

Sounds good. I hope you get your investment back. It could be hard.
