You saying they use the hardware for their own enrichment instead of shipping to customers?
That is not very nice at all...

Nothing new, when you order something with october delivery and you know it's gonna be the end of the month and don't like it, don't order.

Hi,

I want to buy one starter kit and 2 additional boards. On the shop there is marked "October delivery".
So if I order now, when should I expect to have it at home (Czech republic)??
Any real estimate will be very helpfull.

Thanks!

End of October, they're currently busy with 200TH farm.

Is there a logfile for each mining startup? I think its much easier to have such a logfile instead of 5 minutes samples to find the best settings.

A workaround cronjob has been gradually progressing for two days, but is not working yet.

Yes, there's been some long distance debugging going on (thanks to Isokivi for trying stuff out on the real miner) as things are not always working as expected on the miner Sad

. I'd have thought that we'll have something sorted later today.

what is fastclock for?

how can i disable single chips?

Fastclock is something that doesn't exist in the chips, though it was planned to exist.
You can disable single chips by changing AIfDSo to all lowercase in the config (/opt/bitfury/best.cnf)

For example, Chip #1:

Code:

1 AIfDSo 55

to

Code:

1 aifdso 0

Hi,
Niko
I've send you a few Emails asking about bulk chip order prices.
Is there any problem ?

Sorry Marto, I'm drowning in emails, just had someone take over the communication for me. We will introduce new chip pricing on the site this weekend.

Can't wait!

C'mon guys - the competition is pushing : https://bitmine.ch/?p=882 (and https://bitmine.ch/?page_id=863)

So @cscape - where can an average guy go to purchase a 1.5K 0603 resistor in onesie-twosie quantities? I'm sure we can buy them for 0,01 somewhere but the shipping is going to be 1.000 times more than the part...

Actually your H-board is using 1K5 resistor.

tuning best.cnf now.

false nonce and spi/miso err have to be minimized wright?

I just went after the general errors, but I've had very low spi/miso errors all along. Basicly I rose chips that were showing 0 errors and lowered ones that had 10% errors (of valid shares).

Hi, where in the rPI logs do you find valid shares? is that the same as nonces/round?? can I use nonces/round as a proxy for valid shares?

Both are working on eligius, 60gh @diff 128, 45gh @diff 64. I tried 256, but it fell down to 30gh for 2hours tonight.

diff 128 too much for 60gh i think ... 8-16 is nice.

for 60 GH , 32 diff is recommended

BitFury and punin did a great job. They are heroes in the bitcoin community.

The bet is long over. Just confirming that a UNIT is whatever fits on a single M-board connected to a Raspberry-Pi.

And of course I have integrity. If I didn't, I would have created a second account to ask the question. I have nothing to hide.

your account has 16 posts, most of which focus on arguing/asking what constitutes a bitfury 'UNIT', which directly relates to a bitbet you lost.
(the bet was that bitfury would deliver on their promise to deliver units at 400Ghash and under 400w, by the end of august - They did, albeit adding a little extra hardware to compensate a rushed manufacturing process that wont occur again

If they wanted to they could of OC'ed the units and then send us 450+ even with bad manufacturing due to rush order rather then higher quality.

347 Watts @120v

58 Watts @120v

Edit Update

368w @ 120v

60W @ 120V

C) the stat.log is a log thats being rewritten every 5 minutes, the best.log is the best results that autotune has reached. I started off by copying the best.log to /opt/bitfury/best.cnf, which is loaded when the miner starts.

how to copy the file? step by step please.

can anyone give me a description of what .stat.log shows exactly. first 3 colums are clear, 4 and 5 are hasrates (?) and the rest = ?

thanks!

When you measure them off the board, then R02F = 10k, and R01F = 1.0k or 1.5k. When you measure them in-circuit, you also measure part of the regulator IC. The resistance will then depend on polarity of your probe, and measuring voltage used by the multimeter.

The 1.1k - 1.3k people are referring to is not an accurate value, but it can be used to judge the effects of the pencil. Also, if you have multiple boards, measuring before/after gives you a reasonable shot at some consistency.

Measuring in-circuit is always a bit different than measuring the part itself - it's for doing "quick hacks". Otherwise, you'd need to unsolder the part, measure /change/mod it, then re-solder it back onto the board. When you measure in-circuit you are also picking up alternative DC paths through everything it connects to. This doesn't always work so well when the circuit is designed to deal with AC or for parts other than resistors - inductors have much differerent AC characteristics, for example, but would measure at zero ohms...
