[DIY] - Reward $100 | Antminer S1/S3 Blade on Raspberry Pi

[idonothave]

I am running now 2 blades each with own cp2102 connected to easy usb hub with cgminer 4.7.0 at avg 92GHs / 108W (really not bad 1.17W/GHs) with 0.6% pool rejections.

what are your settings?

what are your settings?

sudo ./cgminer -c pool.conf --bmsc-options 115200 --bmsc-freq 0781

(nothing special in pool.conf)

blades are pencil undervolted (https://bitcointa.lk/threads/guide-undervolt-antminer-s1-1-19w-gh-at-the-wall.286480/)

...sorry for edit, I tried 0781 0881 0981 with the best results with 0781

are you running bitmaintechs branch?

if yes, could you try this:

sudo ./cgminer -c pool.conf --bmsc-options 115200:0.55 --bmsc-freq 0881

right now, if my assumtions are right, your running the timing at 100ms which means your not reading the chips fast enough, therefor loosing a few GHs, in the same power usage.

edit:

of course i forgot to order any solder paste... doh! so ill have to wait until it arrives...

yes, seems be better a little bit... 92GHs/106W 0.02% err
and yes, your assumption is correct, default timeout is 100ms

we need to read the chips fast enough for when the chips have anything to deliver, but not too fast to waiste time, and chip speed, so its a tradeoff.. the timings are the same as those found in the antminers config file versus speed.

edit:
on my test board with 200MHz and timing 100 vs timing 55 60 = aprox 5 GH lost if read to slow

even better with 0.44 - 93-4GHs/106-7W

seems like we need to make a speed vs timing list

sure, but as I have noticed, we use different blades, I have undervolted...

edit: it means I will have probably a litle bit different table... and at the moment, for me it is just fun, I have only 4 blades

mine is also undervolted with a pen, but im waiting for my solder paste to add a resistor in parallel to the other ones (i have 20 blades :-p )

i havnt done a decent job on my test board (74 watts / 52 GHs)

yep, I was also thinking about to solder it... would You share then how You did it? If I will be able to make cheap and easy box I will buy some blades and build unit, but only if get consumption low enough

edit: but it would be very difficult to get better then 1.17W/GHs... so...

impossible just happened... 104GHS/109W   0.44 0781

edit: pool rej. 1% ... and there is NO special heat sink, only it lies on notebook cooler simmilar to this: http://www.alza.cz/cooler-master-d-lite-d331897.htm

theoritical it should be possible to get 100 GH vs 90 watts but depends on resistor setting and psu

timing is critical

my undervolt isnt the best, im getting 1.34 (53 GHs 74 Watt) 1 blade at 200 MHz and timing 60

do not be afraid to go below 2.8kOhm... if You would see my multimeter which I used You would laugh... as that guy says, it is not rocket engineering

ive been thinking of trying 2.56 (4.47 + 12 + 12 kohm :-p )

prommising results with 0.27 0781 - 103/108 ... more tommorow

I thought I'd missed something you put out earlier! Thanks for the pointer.

I managed to compile having made the changes to driver-bmsc.c, aka
replace memcpy((char *)&nonce, nonce_bin, sizeof(nonce_bin)); with memcpy((char *)&nonce, nonce_bin, sizeof(nonce));

Then issued:
./autogen.sh --enable-bmsc CFLAGS="-02 -Wall -W -march=i686" --host=i686-pc-mingw32
make

I did NOT include driver-icarus as has been suggested somewhere else, and the device was detected albeit with some issues. Below are the two screen shots i grabbed:

EDIT: I run the executable with the options: --bmsc-options 115200:0.6  --bmsc-freq 0F81

Exactly the same result without zadig) if  zadig is installed -no USB device detected
