is that your queue or your ordee number??

if its your queue then you have a long wait

You'll have to wait for December and January deliveries first - the are still lots of batch 1 (December delivery) orders that have not yet been filled.

I have two for "Feb 1st week delivery":
# 337x
# 353x

whats your queue

Guys
Who received the miner today/yesterday? - what was your order number? - I try to estimate when is my turn...
Thanks!

didn't i warn about this back in November ?  seems like bitmine didn't listen.

Just curious (hopefully not long before I find out for myself) but what kind of PSU did the 600GH unit come with?

Also how long was it between getting notification that your order was 'completed' and receiving tracking info?

Thanks

The host SPI clock must be lower than the intra chip SPI clock, which is derived from the system_clock and a default divider of 64. For the nominal clock of 800MHz the intra chip clock results to 12.5MHz. With that, 8MHz host SPI clock is safe for system clocks above 550MHz and should be reduced otherwise.

What is the significance of the SPI clock values used (4MHz vs. 8MHz)?

In Russia it is exactly 99% of people do not buy!  

with our money

hey we should not insult him or he sued us

can anyone post the height, width and depth of the desk device in cm?

do the desk devices fit into a server rack?

Why this rag giorgiomassa silent. It is generally a man responsible for his words. 

its a kind of magic http://www.youtube.com/watch?v=NLxN0wpFoP8

i think brian may plays on a desk with TURBOMODE

The question was related to his last sentence

I've already experimented with it by myselfe, but as you mentioned, the HW errors went up and in the end I got the same amount, if not even less valid shares than in normal mode.
So, there's no turbo mode at all...I wonder how they wanna fix this with a firmware update...even with an auto-tuning feature...

nothing at all!
if you do look at the list of Zelek Uther

I am the only customer with a decrease of 14 so as peta-mine equipment for private buyers

what the hell ? -> no shipping date , no miner for you at the moment??

What updates are you looking for?

The parameters are well explained: the boards use a ref-clock of 16MHz, you can enter arbitrary values for system clock (which is the A1 clock). The three clock rates used (600, 800, 1000) are those we performed long-term tests in the lab. At 1000 MHz and an ambient of 25°C, the 1.5kW PSU is at its edge - it will shut down if you go far beyond that value. Even if it does not, there is a sweet spot for the clock rate depending on various factors (environment, chips, PSU, etc.) which needs to be found out individually and is useless to go beyond. Your best take is to start at nominal (800MHz) and do long-term measurements with continuously increasing clock by 50MHz.

At some point you will notice that increasing clock will slightly improve your cgminer hashrate, but not that at the pool. This means that the increased processing rate is eaten up by HW errors. Since ambient temperature is a major factor for this sweet spot, it can not be pre-configured. It is also difficult to automate, due to the large number of depending parameters. If someone is eager to work on auto-tuning, I can provide information on how to access the sensor data.

Generally about over-clocking, do your math before you try to squeeze the last MHz out of the box: at nominal (800 MHz) a fully populated Desk gives 1THps for a total of ~960W at wall. At 1000MHz you get around 1.2THps for 1.5kW - you buy 20% more hashrate for 55% more power (and heat). With even higher clocks this non-linear relation gets worse - up to the point where power cost eat up potential gains.

No!!
but we have a new difficulty getting 3,815,723,799
production runs and supposedly even the 70 miner at the peta-mine went about 40 regular buyers are about 110 miner and the 200% increase of staff formerly of much bitmine 2 people?
just ridiculous and then wonder why customers are angry
sorry guys but what would benefit us a news board on the bitmine hompage when everything they have written so far is a lie
or equivalent thereof bit of truth?
