[WTS] 2 * FPGA Cairnsmore --- shipping now

[Cranky4u]

Due to spiralling utilities costs in Australia (elec = AU$0.27kW/h), I am looking to liquidate my two FPGA miners. I have qty 2, serial number 600 series, Cairnsmore 1 FPGA miners. Both have makomk's 220MHs bitstreams installed so they mine at 880MHs per board whilst consuming 80W/h. As a pair they mine at 1.6GHs whilst consuming 0.16kW/h which generates ~0.5BTC a day or 15BTC per month.

I am looking to change over my mining operations to LTC and as such the FPGAs are excess infrastructure. The funds from their sale will be put towards solar / wind power to run my LTC / gaming rig.

I am asking 20BTC + postage each. With ~4 weeks to go onto halving day, these babies should generate their new owner about 15BTC before reducing to ~7.5BTC. If you in a cheap elec zone or already have solar, then break even should be within 4~6 weeks of purchase.

Pls pm me for offers / discussions.

Regards,

Cranky

I noticed this message :

Request for help...

I have 2 CM1s mining in Australia due to high elec costs...Over the last few weeks I have noticed that they only mine for between a few minutes to a few hours (8 tops). Having said this, the best I have done is 2 days str8 mining.

They just appear to drop of the USB line with a "boink" then cgminer reports they are "OFF". I have been using cgminer 2.7.0 > 2.8.4 on a Win 7 system with the same reuslts...could I please get some stability help. (whilling to sheel out BTC for help)

Did you solve this problem? How?

yeah it is solved. I had installed "BOINC" for SETI, Search for Extra-Terrristal Intelligence, a few weeks ago then the disconnects started (hindsight is a wonderful thing) - just trying to use an idle CPU to further humanity. So a few days ago I uninstalled BOINC and it has remained stable since then.

I also upgraded to cgminer 2.9.0 --- not sure if this improved stability but I think BOINC was overloading my CPU as it was up flat out and then starving the FPGAs of data (my impressions).

I'll take both for 45BTC shipped to France with escrow (I'll trust juggalodarkclow for escrow).

sucks you're in australia and I haven't heard of this FPGA

not heard of CM1's...you must have been smoking some heavy shit the past 6 months. Check the mining FPGA pages in this forum for info or http://enterpoint.co.uk/products/spartan-6-development-boards/cairnsmore-1/

happy to be of public service

Okay I've heard of spartan. THese must be some multi use boards that have been made and not specifically bitcoin mining designed

My offer won't last for long. I'm probably losing at least 0.5BTC/day not mining with them if I'm waiting...

Additional questions do you have:

• USB cables?
• a stacking kit?
• a master/slave ribon cable?

With ~4 weeks to go onto halving day

More like 2 weeks and 2 days BTW.

sold to a PM pending settlement.
