BFL Little Single 30GH/s Firmware upgrade/tweaks/overclock

[poon-TANG]

I think there like 45 cfm   ...  I wouldn't worry bout it too much if you leave the covers off the temps will go down.

[monstrs]

Hi to all.

I am looking for this kind of information (how to oc ls) too.

BTW maybe anyone can tell how long with standart shipping order from BFL comes to Europe? I have been noticed that at 17. august it has been shipped, here is the tracking number:

https://tools.usps.com/go/TrackConfirmAction.action?tLabels=CJ422490240US

but it seems not to go further, sometimes that happens when its already outside of USA, any have experience with Little singe orders to Europe? Thanks

Might want to make some phonecalls or check your mail... I saw this on track and trace for Latvia:

So no tweaks and firmware optimizations for ls yet?
does trick with the freezer works on little single?

I'd imagine it would, the firmware they run is virtually the same it seems.
I'd like to hear if anyone attempts to reflash one the way I reflashed my jalapenos

There's 2 temps in BFGMiner,the first (I'm assuming) is ambient temp.The second is the chip temp.

My 30GH'er runs 69C also,so I don't think your reading the correct temp TheSwede75.

I'm intrested in OC'in as well,only if I can get my temps down first,I'll be watching 

Honestly I am so damn lazy that I am just mining through Easyminer (private pool of course) with BFG. Temp was just easyminer output.

Easyminer is only showing ambient temps   Well thats not good!! Try BFGMiner by itself & let us know what your REAL temp is 

Easyminer blows. Doesn't even show correct hash rate in graph, only in BFGminer logs.

BFGMiner was really easy to get going,as I have BEs running too,just follow these instructions 

https://www.btcguild.com/index.php?page=support&section=blockerupter

Heres a sample "target" shortcut:

"C:\Users\pcname\wherever\Eruptor stuff\bfgminer-3.1.1-win64\bfgminer-3.1.1-win64\bfgminer.exe" -o http://stratum.bitcoin.cz:3333 -u username -p password -G -S all --icarus-options 115200:1:1 --icarus-timing 3.0=100

is it much harder to get it work on cgminer?
or LS working only with BFG ?

I too am interested since mine just came in today. Anyone have suggestions for quieter, but still efficient fans? This thing is louder than a 5970...

I mounted my board in an open Mini ITX case and replaced the stock fans with silenx fans (one 120mm and one 100mm). The system has been running virtually silent @30 GH/s for the last 2 months without issues at ~68C. The power brick is now the noisiest component in my setup. http://www.silenx.com/quiet.fans.asp

For me BFGMiner was easier 

BFGMiner uses FDTI drivers,which work with more devices,IMO,instead of Zadig ones.

You can use a bat file like this intead:

Here is a semi blank batch file for bfgminer   
1)Copy the text to notepad and modify what you need then save it as bfgminer.bat.
2)Put it in your cgminer folder and & double ckick to run it.

bfgminer -o http://poolurl:port -u user -p pass

There's more "commands" you can add,even though this link is for cgminer they still work:

I have gpus in my rig already and they are mining scrypt.

So i guess that would be minimum to write -nogpu comand aswell. Can anyone put the piece of code here that they are using with they LS ? In cgminer and BFGminer. Currently i am using only cgminer.
Also does Cgminer uses more CPU resources? Thanks for answers. I just want to run that LS as soon as i get it.

Does anyone tryed to put them under cold like someone was doing with japalenos to get low starting temp for greater performance?

P.S. i would want to configure and see .bat file only for little singe, not using gpus

P.S.S. Would these lines could work:

CGminer:

cgminer-nogpu.exe -o http://poolurl:port -u user -p pass  --enable-bflsc

BFGminer:

bfgminer -o http://poolurl:port -u user -p pass

[monstrs]

could get it work only with BFGminer, anyone can share the cgminer comand line?

Got my LS a few weeks ago and it works OOB with a raspberry pi running MinePeon.  Currently using the MineNinja BeagleBone Black; had to recompile cgminer 3.3.1 (NOT 3.1.1) with the --enable-bflsc flag before it would recognize the device.

Stable as a table @ 29.8 GH/s and 61-65 C

[Red_Wolf_2]

Congrats on getting the unit monstrs!

[monstrs]

My LS is running stable so far with 68 celsius, 29.69GH/s

Do enybody expirienced that if they turn on LS, that has been in cold for a wile, does it mines faster? I have red something about it regarding jalies.

I've restarted my LS from full load (just restarting cgminer) and from a dead stop (room temp and just powered on) and it always seems to average around the same speed.  I'm not sure if it just has better airflow when it operates or a different type of system check on the chips.

It should be common across all the Bitforce SC range. On power up (in the open source firmware) the unit runs a series of self-tests to determine a good operating frequency for a chip and whether the engines in it are working correctly. If they aren't it disables them. Cooling the unit can cause engines to be more stable and clock frequency to be set a bit higher, resulting in a higher hashrate while the unit runs, although there might be more hardware errors.

One thing I have noticed, the power-on self test for the open firmware takes a lot longer than the stock firmware did. I am wondering whether some sort of calibration is run beforehand during burnin and fixed values are set on the various units based on the burnin results. Doing it this way would allow the faster power up time and also a more consistent hashrate irrespective of environmental changes.

To anyone who cant stand the noise, take off the side plates that cover the fans. My temps dropped from 69-70C to 61-63C. You will have exposed fan blades but the noise that almost sounded like a vacuum is now gone and temps are better. Considering the amount of air these fans are pushing BFL totally put a ridiculous type of fan cover which contributed to the whine before I removed the plates.

So is there a custom firmware for LS ? Are you using it? What are the max speed ?
Also das anybosy tryed to put that 100mm fan otherwise, when it blows air on the cooler? Temps are better?

Yup, it doesn't make the unit much faster but less noise and lower temps. I also flipped the top fan 180 degrees, now it blows down into the heatsink.


Temp 52C (27GH)

is it possible to connect it to PSU 6pin power adapter? How much W does it need?

[Unacceptable]

is it possible to connect it to PSU 6pin power adapter? How much W does it need?

Yes,it works    About 130 watts  

My Kingwin 1000 watter does just fine  

Each 6 pin SHOULD be ok to near 140-150 watts,so its just under the theoretical max.

[crazyates]

Mine sometimes bounces between 30.5 and 31.5GH/s, and each time I turn it on, I don't know which I'm going to get. I tried putting it in the freezer for an hour, and I got 30.5, so I'm not sure what causes it to get the higher number.

And ya, I'm using CGMiner. For those saying it's easier to run BFG because of driver issues, that's a non-issue. It literally took me 15 seconds to run zadig and install the new drivers. Then I run the cgminer-nogpu with a basic config file with just my pool info, and it picks it up no problem. Very simple and hassle free setup, and I was up and running within 60 seconds of first plugging it in.
