[GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher

thanks  2.5 mm plug or 2.1 ?

thanks  2.5 mm plug or 2.1 ?

both work, but 2.5 is the proper size

[miaviator]

So how would one dual mine BTC/LTC 20 of these using windows?

Is there a way to do it without the controller and just use a single pc? I hear you get better hash rates and less resets when you don't use the controller.

You would create 40 total scripts and a 41st to kick them all off.  I'll look for the post and put it in the windows section I know there are some people running 20 in scrypt only. 

[worldlybedouin]

worldlybedouin add --dual to the commandline of minerd and skip freq

Yep I had done that just copy/pasted the wrong line of minerd command syntax. 

I'll give it another try using the latest write up from miaviator just in case I am remembering things wrong in my old age

40 windows then right? This is the only way for dual mode mining?


And thanks for the awesome tutorial! 

[asiabtc]

thanks a lot for your setup guide.
great works.

[brioche]

Great setup guide, thanks soo much.

In linux I can do one cgminer to run all the miners and 10 cpuminer to run each scrypt portion.

So you may be able to get away with 21 windows

Actually I'm quite interested.  You want me to assist?

[miaviator]

Added more linux specs for single and dual mode.

Moved power supply replacements to the top.

Integrated more questions and clarifications into the OP.

My units are red - what are the practical differences - should I feel speshul compared to the golden peasants or just jump off a bridge?

Sometimes the units do this :

Code:

0: >>> LTC : 55aa1f2816000000
0: >>> LTC : 55aa1f2817000000
0: >>> LTC : 55aa1f000000000000000000000000000000000000000000000000000000c0ff3f00000009a1993dbcaaeb744a2f84d36bd2540e97e4df56486ff3ead1a12a70d0db998700000002d50931d314c0e2070a387b02a95ca2605c1e61b569d425fc9a34ac01588e7f0aecdc35f508449ec1eaf003bfa0a02374a6f0470e0b9719c94201c16e6941a0155313d8f31c08174500000000ffffffff12345678

for like an eternity , with pools not reporting any hashrate. Any magic tricks to make them do the YAY or is everything as it should be?

Miaviator or anyone running with RPi.  I have it running with each session but for some reason regardless of which USB Hub I run (using a 10port I use to use for USB miners) I only get about 150-200khs per worker at 800-850.  In Windows I had 5 running last night at 300-350KH/s per.  I am running the Scripta release on RPi with Drphranz modified version.  I am loading a second SD card to try out Minepeon (since its based on Arch) to see if it helps any. 

Also I know people talk about firmware but is that just for the controllers or is there firmware for the Gridseed units themselves?

There is some difference which I have yet to find.  The lack of yay usually means you are not submitting shares.  You could try another pool but it sounds like you are submitting shares as you said sometimes.

Firmware for the gridseeds themselves.

Can you try running just one device off the Pi and report back speeds?

I'll have to check the firmware again on the units.  I have the software Lightning has but it couldnt connect to the device (my guess the version I have was looking for the white button versions).

Installing Minepeon (since I am used to Arch) and configuring and soon as its done I'll swap USB's and try it out.  Thought maybe a latency issue due to USB hub, and maybe so.  Post up here in a few.

[Powell]

5 minutes of hashing...  The total shares are from over last few days of messing around.

Powell_2 = RPi running Scripta (850 freq)
Powell_5 = My desktop Cpuminer (the latest build that helps with power) at 850.

USB devices hate me LOL!

[chanberg]

Wow didn't even know scripta worked for 5 chip gridseed

[Powell]

In about 10 minutes (so they will have some hash time in them) I'll have a screenshot from my Lenovo X1 Carbon running the miners on the same USB hub.  Only issue currently is I'm stuck at 9 due to not launching with COM10+.  I'll read first page again because it may have been addressed already LOL!

Also .1BTC from me as well for the help!

[Powell]

#9 is the one unit I am not running due to lack of COM ports (10+ no worky ).

Still a HELL of a difference LOL!  Only thing different is the laptop (Windows 7 x64) instead of RPi.  The hub is a powered 10 port Roswill.

Maybe I should leave my RPi in the drawer

[Powell]

I left my Beagle Bone Blacks at the shop which sadly I had a build I was going to try but the crap USB Hub they sent was the problem (kept power cycling itself) but it ended up doing it on everything I have LOL!  I will grab it tomorrow since its 11:30 here in Houston and raining so not worth the 20 minute drive and me spending hours yelling at it LOL!!!
