BFL will tell you that the under performance was disclosed in the spec (+/- 10%)

Of course if you are KNC then your spec was 20% understated.

So the 60gh I paid for got me 57gh so lost 5% of what I paid for.

7Gh Jallys were 8.5Gh and 7.3Gh so I am almost even.

Today I took all my BFL gear apart, took off covers, flipped fans (boy these things were put together like crap) and only netted 2gh.

Flashed my KNC with the lasted Firmware and it is doing about 5gh better so 30 minutes invested got 7gh more net.

BFL Single blowing up? Be careful with the hacks, I'll buy the blown ones. :-)
https://bitcointalk.org/index.php?topic=343753.0

There was another user I pointed in your direction who was supposedly mining at stock speeds.  My original day 1 unit only mined at 53GH/s and failed after 7 days- I had a downtime of over 2 weeks costing more than 15 BTC.

Obviously people with stock units should try to RMA back to BFL and hope they can mine a little more afterwards or find a sucker to buy the little M80s in disguise.  People with hacked 30/60s have brass balls (maybe sparky ones shortly).

Had trouble opening a overheating mini rig, so my buddy Thad peeled it open...no miners were hurt in the making of this video.  Actually gained back 100ghs lost to overheating...


Is your BFL mini rig overheating? No problem, just give Thad a call. Watch as Thad peels open this mini rig as if it were a cardboard box.

My BFL SC finally arrived today.  I plugged it in and was only getting 26 GH/s.  So I unplug it, remove the power cord, and wait a few minutes.  When I hook it all back up, it now caps out at 15 GH/s.  Any ideas?

Wow, out of 45,000 units shipped, you managed to find... wait for it... 12 failures.

Now, I don't claim to be a math whiz or anything, but... I'm gonna say the failure rate is quite acceptable.

Lets be generous and say you found 1/100th of the actual failures, so that means there would be 1200 failures... a whopping... wait for it... 2.6% failure rate.

Holy hell batman!  Stop the presses!




If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

yeah Josh, the hardware is fine, thanks

hey, about the delivery schedule...

My brand new single lasted almost a whole month before dying.  I sent it back, and they sent a replacement fairly quickly -- just 8 days of down time.  We'll see if this one lasts as long.  Can't complain about hardware that only spends 27% of its time in the shop.

BFL outright lies about delivery dates and produces total crap for product.

Tips much appreciated! 1PPJHDawPvjh6MEzsvXrMYLgpLmyAaNXUc

PSA for EU BFL Customers: BFL single power supplies do not automatically switch to 240v power and will blow up if you plug them in before manually switching them. (fkn bfl cheapskates...) [did this] [loud pop sound] [quick trip to the computer store]

Its a shame you're having so much trouble. It could be overheating? I've read about ppl turning the fans around to blow ONTO the chip rather than suck hot air out. If you're comfortable opening it up, check which way the fan is blowing.

hugaddiction

it ran at 30 for a while and then just shut all the way off. now its trying to reboot. Normal? or do I need to send this fucker back?!
is it possible Im not giving it enough power? like I should try a different outlet? now I just sound crazy...

Sonoflopez

Can you post a picture? I kinda want to see it.

hugaddiction

I'll try http://i.imgur.com/cSwaTvq.jpg

It's a little single. I run one of those too.
The PSU they include with the unit is quite bad Imho. Try with a quality ATX power supply (400W should be sufficient with a little single).You'll need to install drivers on Windows, linux supports it natively, hence I would prefer linux.
I use the my device with bfgminer with the -s ALL parameter.

yeah, that last, I'd be careful with that, there are only temperature sensors in certain places on the board, flipping the fans may lower readings on the sensors, but other areas of the board may not get sufficient cooling. lots of threads.  The long term effect is unknown.
