My first batch of ten BFL singles arrived this week and finally gave me something to write about...
Delivery time was 12 weeks from date of purchase.
Out of the 10, one has a top fan that does not work, we'll be requesting a replacement today. BFL's customer service is pretty responsive and have kept me well informed so I suspect this will be an easy return process, but the timeline to get a replacement may be in question. Power draw at the wall for most of them was at the advertised 80w, a couple leaked over 1-4 watts, but most were dead on.
They are connected to a slim line Dell pc using two usb hubs and sitting in a climate controlled data center.
I'm using bitcoin-miner.exe from Ufasoft with the following params:
-a 10 (getwork requests every x seconds)
-t 0 (stops the miner from using the cpu to mine)
-o
http://name:password@pooladdress:8080 (username, password, pool address and port)
Performance: According to bitcoin-miner, I'm pulling between 6600-7300 hash, which is right in the wheelhouse of the advertised 830 +-10%, but on the lower side. I have not investigated if any of the devices are suffering from heat issues.
I'm going to let is run in the wild for a few weeks before I start tweaking with the experimental firmwares.
I'm going to also mount rack fans to force air through the rack shelves they are sitting on. Maybe add a thermostat to the shelf.
Oh, the hot-swappable feature of bitcoin-miner works as expected, you can plug in nodes to your desire and the software sees the new devices and puts them to work. Unplugging devices works the same, but an error message flashes across the console screen informing you the device errored out.
All in all, I'm happy to say that the products perform as advertised.
Post any questions you may have, I need to reach my 5 post limit SOME day to get out of newbie hell
