LightningAsic usb miners based Gridseed GC3355 Tech Support Thread

[Andareed]

If anyone interested I've modified Andareed's version of cgminer a bit to let you better finetune the gridseed units. There's a big variance in the resistors they used as voltage references so every unit has a different maximum frequency they can run at.

https://github.com/girnyau/cgminer-gc3355

New frequency table: 800, 813, 825, 838, 850, 863, 875, 888, 900, 913, 925, 938, 950, 963, 975, 988, 1000, 1013, 1025, 1038, 1050, 1063, 1075, 1088, 1100, 1113, 1125, 1138, 1150, 1163, 1175, 1188, 1200

You won't need the ghz ones however unless highly overvolted

You can also define a base frequency as usual, then set per device frequencies by the units' serial number if you want:

--gridseed-options freq=888 --gridseed-freq 8D74488A4949=900,8D96227B5449=900,8D7357785355=875

Factory units running since ~48 hours without any hw mods but the fans desoldered:

Cool! Not sure that the resistors are the reason for the variance. The four I measured were within 0.1% of spec. I assume this is just silicon quality differences in the actual ASIC chips.

All right, the new frequency table is:

700, 706, 713, 719, 725, 731, 738, 744, 750, 756, 763, 769, 775, 781, 788, 794, 800, 813, 825, 838, 850, 863, 875, 888, 900, 913, 925, 938, 950, 963, 975, 988, 1000, 1013, 1025, 1038, 1050, 1063, 1075, 1088, 1100, 1113, 1125, 1138, 1150, 1163, 1175, 1188, 1200

Would someone kindly provide me with a compiled version for the raspi? Even better would be a complete image... I grew up using dos and windows... but I'm not good @ linux :-/

Anyway. Some people were talking about the raspi version with scripta getting stuck over night. Even with the changed line someone supplied it crashed overnight. I found a donation cron job running every night for a short time. Just deleted that thing and the raspi works very fine now...
But would love to implement the latest frequency setup.

Best Regards

Should not write about the raspi... just yesterday night it stopped working and I had to powercycle. Maybe I should lights on during the night?

Any one else has this problem or are all just fine now using the raspi + cgminer + scripta?

There is an issue when using the Scripta image.  It works for some folks and doesn't for others.  The devs are working on this.  Until then I suggest you just run RasPi + CGMiner only...I've been using that and it's incredibly stable.  Along with the tweaks to cgminer that Girhes made, I now have more fine grained control over overclocking them and it's working out quite nice.

Sounds really nice. I feel I don't need the scripta thing...
Would you mind doing a backup of your sd card and sharing it?

Just to play around I'd try to use scripta on a dedicated raspi to sum up all my miners... but that's later... first of all I need reliability on the process.

Sending donations to the Scripta guys and Andareed

[Ofenkaese]

Very cool, thank you very much for sharing the link. Will also go to donate.
Do you also have an image version containing the detailed frequency setup? Would love to test that.

Please don't forget to donate to him as well if you like the modified version he's made!  Donate to Girhes here:  https://bitcointalk.org/index.php?topic=477709.msg5752544#msg5752544

Once you download this version, you'll want to backup the existing one by renaming it to another file name.  Then take this version and change it's name from cgminer.girhes to cgminer instead.

Also, don't forget to change permissions on this file so you can execute it.

Awesome work, 988 works really well with 1.26v

[flounderella]

Hi Quick q: Is v2.0.2.zip still the recommended firmware to use?

Where can I download this?

Edit: you mean the wiibox or LightningASIC firmware? Wiibox is up to 2.0.7, but it changes your SHH password after 2.0.3.

Sorry, meant wiibox. Thanks. Ahh I see. Oh well ...

[Girhes]

We have a few units where only a single chip holds the other 4 back, so I'll brobably also include per-chip settings in the near future. You can verify this by adding Andareed's per_chip_stats feature to the options, running cgminer from ssh and maximize the window so you'll see the stats at the end of the line for each device. HW errors are displayed between brackets for each chip:

GSD 0: 8D74488A4949  900 MHz | 382.0K/381.9Kh/s | A:344128 R: 256 HW:64 WU: 1.3/m N: 303[62] 264[1] 310 238 284[1]

I wasn't aware of this feature in Andareed's version of cgminer...

Is the "per_chip_stats" a command line option for running cgminer?  
Ex:  

Code:

./cgminer --per_chip_stats

Or is it a compile time option?  
Ex:  

Code:

./configure CFLAGS="-O3" --enable-scrypt --enable-gridseed --per_chip_stats

Edit:

Figured it out!

It's --per-device-stats from the command line:

Code:

./cgminer --per-device-stats

[Girhes]

You just add it to the gridseed options: --gridseed-options baud=115200,freq=850,per_chip_stats=1

My version also has it as I forked from the original repo, so you can use either one to check it out.

Unfortunately I don't have the tools or knowledge on how to compile this for windows, else I'd do it for you.

I'm getting very nervous about setting up my LA3M having read this thread. I was thinking about using Raspberry Pi, but I have no technical acumen whatsoever...

What are the honest chances of a noob getting this running in an evening?

You can still just run it with the supplied TP-Link controller. A lot of people have switched to avoid resets and optimize performance, but I've read that there's an updated firmware for the TP-Link coming from Lightning Technologies that will resolve a lot of the issues.
