Will a brand new rPI model B(eg. bought from element14 with standard Linux based OS on a 8GB SD card) work as well or I would need to make a few modifications in order for it to work?

You'd need the software from bitfury (so ideally their SD card image), but I believe that the RPi hardware itself is not modified (just plugged into the m-board via the GPIO pins). Bitfurystrikesback will throw in an RPi + SD card etc. with the starter kit anyway, so there's not really any need to buy another one (unless you are worried and want some backup hardware in case the original RPi goes down).

EXACTLY! Cheesy

Punin ,
Thank you for the  answers.
Today I got the sample chips by Regular mail and punin is going to refund me the express delivery cost.
In the envelope there were 20 sample chips (ordered and paid 16) , thank you Punin.

During populating the board and unwrapping the chips we find out that there are not 4 but 8 extra chips.
So 50% bonus..
Thank You Niko

Short update:

We're working on software updates. Chainminer v2 with new web GUI for tuning chips is in the works and should be ready by the time we ship.

We're getting plenty of chips starting 20th of september, so all of you planning on your own boards, go and order them now. The september chips have advantage over october chips in delivery time (they are more expensive).

We should be getting boards next week, so we're looking very good regarding shipping everything in time in october. We will start with preparing the 400GH units (as these require hand-picking of the cards).

I'm really busy on some other developments right now, so Lisa is helping out with communications. So please address your questions to support, not PM on forum.

Has the solder process been modified or is it still possible to get bad soldered boards with the october delivery units?

Punin - what about pricing for October chips?

Short update:

punin,

given bitmine.ch offerings for december... 2 TH/s 11.5K EUR, are you going to offer a november 5 (pack of) 400 GH/s units at a little higher price point? Smiley

Energy wise you should still be a little better than their announced 1.7 KW.

I can send the unit to different address provided it's in the same country, and you send new address before we ship.

A word of warning to those of you, who are working on your own case for BirFury: the 6-32 screws (used for PC case and 3.5" HDD) won't fit through the holes in the M-Board. You need instead to use the smaller M3-0.5 screw (used for DVD-ROM mounting in PC). It is very tight fit even with the M3 and because of that there is very limited margin for inaccuracy.  Undecided

Punin: it would be nice to have the holes slightly larger in the future M-Board revisions.

@Punin - I have a couple of questions if I may:

Are the reels of chips tested and/or speed binned, or is it pot-luck how many of the chips will work and if they do, how fast they'll hash?

Do you have any plans to sell quantities of < 1 reel at prices that would make buying chips rather than H-boards an option? The pre-order option of lots of 10 chips was rather nice!

Cheers.

Our chips have not been binned. Due to our design, we're seeing extremely high yields on our chips, and although there are differences in speed, we feel that binning is hardly worth the effort. Should there be a higher than 0.5-1% failure rate, we would consider compensating.

We will continue to sell small quantities to anyone interested, but at this time we have very few chips left in trays. The price will be adjusted shortly. It's a loss business for me actually, but I think it's important to have smaller amounts of affordable chips available for prototyping etc.

We should be getting boards next week, so we're looking very good regarding shipping everything in time in october. We will start with preparing the 400GH units (as these require hand-picking of the cards).


Hey punin. Great work and thanks for the update. Just wondering what amount of hardware makes up a 400GH unit?

We are aiming at 16 H-cards + 1-Mboard + RasPi, but this varies depending on the hash-rate we get from the cards. Some august units consisted of 2 M-boards to fulfill the promised 400GH performance per unit.

Anyone here with a Full kit hashing under 370 GH/s? Have you tweaked your unit manually?

Let me try (SSH) or try these instrucions:
0) Do not use fans or any other active cooling
1) Set the clock speed to 55 for every chip (xx aIfDSo 55)
2) Let it hash for 10-15 minutes
3) sudo nano /run/shm/.stat.log
4) Turn off (xx aifdso 0) all the chips that are hashing slower than 0.3 GH/s
5) Lower the clock speed to 52 for every chip that is hashing 0.3-0.7 GH/s
6) Lower the clock speed to 54 for every chip that is hashing 0.7 - 1.1 GH/s
7) Save it to /opt/bitfury/best.cnf
Cool sudo reboot

I've tried this with three Full kits and several Starter kits and it seems to VERY good way to gain some hashrate easily.

What kind of gains have you seen using the steps you have mentioned above?

MXRider,

Gains depend on how well you have already tuned your unit. This is just a general guideline to manually tune your unit without wasting precious time. I've got over 370 GH/s from every Full kit I've tried this with. So if yours is hashing slower than that, you might want to give this a try Wink

It seems to me that I have to revise my first impression

For me its like the less I touch, the better it gets. Seems to be a pretty self containing ecosystem, I like that, I'm a lazy guy  Cool
because
Anyone here with a Full kit hashing under 370 GH/s? Have you tweaked your unit manually?

a little fine-tuning à la MXRider indeed brought me an improvement of about 3 GH/s, stable. These chips seem to favor consistency over everything else. No autotuning, no draft, no fumbling around, constant settings are rewarded by what they were made for and like to do the most, hashing joy- and powerfull as fast as they can.

Amazing! My noncerate has just grown from 44 GH/s to 49.35 GH/s.
