Topic: BFL Little Single 30GH/s Firmware upgrade/tweaks/overclock (Read 16066 times)
Just had mine arrive, not sure if I'll keep it or sell considering how long it took to get here and current difficulty. Still would be interested in any tweaks for the unit.
Has anyone built an optimized firmware for this one yet? I have downloaded and compiled many of the ones released from BFL through Luke-Jr but 1.2.6 and 1.2.8 didn't even run. It was apparent from right after the flash that they did not work because the fans did not spin and LED4 flashed continuously. Versions 1.2.7 and 1.2.5 worked but my hashrate was like 15-17 Gh/s. I only have a supposed 25 Gh/s device since I didn't pay for the upgrade but in reality it came hashing only at 21.5 Gh/s (that's right "2 week Josh" who never told a lie in his life, a full 14% less than advertised not the +/-10% you promised) anyway though I have tried GenTarkin's firmware from here https://bitcointalksearch.org/topic/ann-custom-bfl-firmware-tested-5-7gh-pool-meas-improvement-on-60gh-singles-310196 and it did raise my hashrate significantly but it also raised my HW error rate from about 2% to 8% so the hashrate increase is basically a wash. My suspicion is however that something optimized for an LS might increase hash without the increased error rate.
I'd hope it would be easy enough to flash the device ... but not many will be willing to risk voiding their warranty.
Considering the 30GH LS is only half populated I wonder how hard it would be to add more BFL ships to bring it up to 60GH?

Anyone know of any attempts to reflash it yet?
I've received my LOUD little single today that was ordered 12th Dec 2012, seems to be built September 23rd and has written on the board 'using firmware 278' if that means anything to anyone.

BFL have only shipped about 10 LS's so there's not much of the community out there who can experiment. "No Little Singles shipped today" - Jody's blog. It's the new "2 weeks" comment.
I have my LS already almost 3 weeks. And i preordered it at september 29 2012. Do you think, that it was only 10 LS between june 23. and september?

Bump... because I'm interested in trying an overclock as well.
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.

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.
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?
I'd assume there is, but only having Jalapenos I haven't seen it myself. I have however browsed through the source code and it contains defines for all the product lines, you just need to comment or uncomment each lot as required before compiling.
Has anyone tried flashing their LS or S yet?
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.

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.

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.
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)

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.

Congrats on getting the unit monstrs!
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
