1GH/s, 20w, $700 (was $500) — Butterflylabs, is it for real? (Part 2)

Imma just leave this here for tonight...

Inaba, glad to see you're the first with one of these things; you put in a lot of your time for our benefit. If I may ask, what O/S and what mining software are you running it with (I think Fred0 was wondering about this as well)? I understand that ufasoft and cgminer claim bitforce support, and I'm not sure what software these will ship with.

I've been watching this thing ever since it went online. I noticed it quickly stabilized at around 830-850 Mhps, but once it submitted about 600-650 shares, its speed dropped to around 750-770 Mhps and it has remained at this low speed for at least the past 10 minutes (shares as I type this are 787 shares, speed 758Mhps).

Is this one of the prototype units, the one with the power problems, or is this a production unit representative of what will ship? Any idea why the sustained speed drop after 20 minutes or so of operation? Thermal throttling? It is worrisome.

EDIT: false alarm.

Yeah, an average hash figure would be nice, at least just for this first test.   Poor old Inaba, he's going to get pestered so much over this until the rest arrive

[simonk83]

at least people are now asking him reasonable question and not attacking him personally.

Yes, well hopefully he has those people on ignore.    Thanks for the link Inaba!

IT LIVES!!!!

Operation "replace the 6 GPU's in my office" might have to be undertaken.....

i hope he takes all the time he needs to reply, after seeing all the bullshit and abuse directed toward him since he did the initial testing.

[Unacceptable]

Awesome Inaba

Looking forward to your review

This is what I've been waiting for

We're down to 715Mhps @ 1308 shares now. Not looking good. That's even outside BFL's claimed +/-10% variance (I was hoping for +10% myself).  

EDIT: false alarm.

Depends when you look at it.  Right now it's 777Mh.   That's just the way it works unfortunately as the hashrate is worked out by the number of shares submitted within a certain time.  It's not all that accurate at the best of times.

That's why an average is handy.    

EDIT:  Now it's 858Mh.    Don't get all worked up by the displayed hashrate on a pool site.   Even cgminer is flaky like that with GPU's, but the average displays a more useful figure.

If Ianab has the start time we could look at total shares / total time to get more accurate "runtime" hashrate.  Of course anyone could it themselves by simply taking a time stamp and the share count and then check it again in 2, 8, 24 hours.

Now I can buy all your 5970's for cheap. You can spend the big bucks on these things..

2252 shares at 7:08 UTC. That's 838 shares in 4560 seconds, or 789 +/- 27 MH/s. Let's see what it is in another hour.

Man does not live by bread alone. And on the seventh day GOD created Half-Life 2!

I wish GOD would create Half Life 3, maybe then it will actually become a reality. But this may explain it: https://i.imgur.com/bUUke.png

Now for something more on-topic. Does anyone know if the current price on their website is here to stay or if they will raise it as soon as they smell the money?

update:

shares since reset 6748 @ 2012-02-14 13:42:12 (UTC)

So if my calculus is right.

7 hours, 49 minutes, 24 seconds later = 28164 seconds.

6748-1414 = 5334 shares
5334 shares * 2^32 hashes per share = 2.29094E+13 hashes
2.29094E+13 hashes / 28,164 seconds =  813426912 hashes / s
813426912.3 hashes/s   / 1000^2 = 813 MH/s

Right?  If so looking good for first 8 hours.

[bulanula]

Where is the RIG BOX anyone

[Inaba]

My home internet connection is being a bastard, so I'm getting some timeouts to the pool which is affecting the hashrate and the displayed rate it will be lower than actual hashrate,  In retrospect, I probably should have put it in the datacenter, but then I wouldn't have been able to get pictures and such.  

I'm calling Time Warner today to ask them WTF is up.

Numbers and other stuff will be coming tonight.

I have an older data point that I used. 02/14/2012 04:51:26 UTC was 741 shares. Using that point, I get about 803.5 MH/s.

Nice.  Will be interesting to look at 24 hour run.  Was hoping BFL would let Inaba do that 3 months ago.  Will be nice to finally see a solid 24 hours "in the real world".

[Mousepotato]

Power draw?

[SysRun]

Money to burn! Lets all show Inaba our appreciation by sending a BTC his way. Altruism is a good idea.
