Hash wild and Hash_Fast,
QG

why to take one board out?

I'm curious why one board is out too.

[QuiveringGibbage]

i am building individual shipping crates for each board so I can post them off easily. Shipping the lot at 18kg was heavy, bulky and expensive.

The plan is to have 3 smaller, more manageable hashing units. Made from left over mdf, the hashing board is secured to the crate frame along with the radiator and fan. You can pick up each unit with one hand and also continue to mine in the crate.

It seems that HF will not send out Sierra or process refund any more...

I can confirm they are shipping Sierra's just had my fedex email confirmation, it should be with me by Monday.

seems like a good idea. i may do this with my Sierra that was delivered today. it seems like they had a lot of problems out of the included power supplies since the 2nd gen doesn't come with any power supply and requires a 1200 watt instead of an 850. So, do you notice any improvements using that Antec 1200 watt?

why ppl still want a 1.2T HF miner at the cost of 20+ btc or ~7K USD? There are a lot of 1T machines with price of around USD 2K only (e.g. http://www.lketc.com/engoods/show/580.aspx costs RMB 13800, and it is next-day shipping).

[Legend21]

Its that people have no choise, already order previous Jear. and now have no choise to acept this. its not their fault..

KEN is currently getting fitted for his shipping crate. in any case I only have the 2 USB cables to connect so KEN will need to piggy back of AL. If you plan on hashing your Sierra boards separately, you will need 2 more of these USB cables (left side in pic). 1 is provided (right side in pic) with the Sierra unit.

So, do you notice any improvements using that Antec 1200 watt?

I did not notice any better power performance running on different PSU but I wasn't looking out for it. I do not know why the 2 X-850 PSUs that came with the Sierra are not working with the boards. I believe the PSUs are fine but just can't get the boards to work with them. On a slave board it works fine, but if I connect to a master board I can an error in cgminer (can't remember exact error).

OMG. Hashfast is "as poor as church mice"....

Poor hashfast.

[fthisforum]

hey guys. i'm trying to get my sierra to run on windows 7. i'm having a hard time. for some reason windows isn't able to install driver. all it shows is M1 Module. when i run cgminer i get the following message.
see README.txt file included for help
hashfast detect (5:1) fail to initialise (incorrect device?)

[solarion]

cgminer + winblowz + usb asic = zadig. Are you using zadig?

[QuiveringGibbage]

so i've started tuning each board's Clock speed and the results are somewhat surprising:

My original setting and hash rate with the Sierra was clocked at 604MHz hashing a total of 1.3THs (~433GHs was expected from each board)

Now I am hashing each of the 3 boards individually with it's own USB cable:

Code:

 0: HFB KEN     : 700MHz  85C  81% 0.79V  | 725.4G / 860.0Gh/s WU: 12021.7/m A:  675079 R:  437 HW:  311
 1: HFB ROBERTA : 700MHz  85C  61% 0.78V  | 674.6G / 513.1Gh/s WU:  7170.9/m A:  270783 R:  366 HW:  73
 3: HFB AL      : 583MHz  82C   5% 0.80V  | 537.3G / 587.6Gh/s WU:  8209.1/m A:  564308 R:  688 HW:  626

Yes, that's a single Sierra board (aka BabyJet) hashing at over 800GHs (wall measured to be ~610w for this setting). So my total hashing speed went from 1.3ths to ~1.7THs. I am still in the early stages of tuning cgminer for the best hashing rates and I need to repeat these test results. But looks very promising to hash those board individually.

Anyone else planning on hashing their boards individually? I'd love to compare results.

cgminer has issues with reported speeds, so the results are inaccurate there. Each ASIC with all the cores enabled can do 768 Bitcoin hashes per clock, so if you are 700MHz your absolute maximum hashrate is 538GH/s.

i c i c.. as I did try the 700MHz again overnight to try to get KEN up to 800+GHs and yeah it only hashed around 500GHs. Will need more testing and will display results.

I did get up to a total of 1.5ths with the pool when all 3 boards were hashing at the same time:

thanks! got it working. that did the trick.

[kevin911]

so I have received my sierra but at least once or twice a day it zombies  and doesn't kick back in until I restart cgminer
does anyone know why this happens?

Are you overclocking it (too much)?
