Some further interesting observations.
Originally I was running the modified cgminer on my big beasty Windows machine for the unmodified gridseed. This seemed to work fine, and setting the clock to 850 resulted in low to no hardware errors. Setting the clock to 900 ended up usually on par with 850 after HW errors and such.
I've now been running it on linux on an old netbook I had lying around. Strangely enough, the gridseed seems to be doing better on linux. I have the clock set to 900 and it has been rock solid. At 950 it still generates too many HW errors to be useful in my opinion. The pool also verifies the better performance.
Has anyone else noticed this with their gridseeds/miner combos?

Has anybody tried desoldering the fan in PSU? I think it's useless if PSU is drawing for scrypt only mode (70-100W out of 330).

Not really sure what I am doing wrong with CPU miner I am getting no accepted shares. Stratum is detecting new blocks. It does say it was unable to open the comport "GetLastError=2". The miner is on com4 and that is what I have the bat set to. Same issues with CG miner. Think maybe I have the drive installed incorrectly, any insight?
Depending upon which Window's operating system you're miner is on, try restarting the comm port that your miner is on. Start/Computer/properties/Device Manager/Ports (Com & LPT)/'your comm port driver'/disable/enable..
No change?
Go back to comm port properties/Port Settings/Advanced/ Receive Buffer 8 - Transmit Buffer 14.
'OK' out of there, then restart that port again so the new changes surely take effect. I am not sure if the settings will adjust and reset while live or not, but I doubt it.
These settings helped my miners to stop crapping out often like, every 20 mins' to a few hours.
Now they only randomly to mass crap out after more than 24 hours! Woo Frikkin Hoo! Yes, it's a good gain but I still have to re-pain!-in!-the!-ass!-start them often! I want there to be no need for me to intervene!
These are machines. They can be programmed to do what they are told. That's all they do anyway!
They also handled no shares being submitted 'yay' . Lots of yay's 99.95949993233% of the time at 850 clock. Seems to still be the optimum clock speed in spite of over-clockers efforts, up till now. Oh well!
Okay....
Try mining again. Happy hashing!
Worth a try! As usual, try diss stuff at your own risk
Gewed luck!
Lemme know.

Had the same thing, I thought its DOA. Play with power, if it's not hashing - it doesn't receive power from PSU. Unplug-plug, try to re-wire it to PSU. Helped me.

Sorry can cgminer control more than 10 gridseed? Whenever I add an 11th, it does show up in cgminer with hash rate but never accepts anything?
GSD 10 is the one. I added them one by one with cgminer running
Here's the command line options to run cgminer:
--scrypt --gridseed-options=baud=115200,freq=850,chips=5,modules=1,usefifo=0 --hotplug=1

--scrypt --gridseed-options=baud=115200,freq=850,chips=5,modules=1,usefifo=0 --hotplug=1
change --hotplug to 5
Yup, tried that. Narrowed the issue to one of the 11 units. Tried cpuminer as well as bfgminer aswell. They can detect and start hashing but this particular gridseed never gets any accepted shares. I'm thinking its a DOA. Since its now isolated, I'm going to try to see if its possible to flash its bios or play with clock freq
Unlike the others, only a green
light is blinking...
Thanks!
Please do keep us all posted on your progress.
Sounds important enough for others to know what can or can't be done with DOA's.

Will a standard AC adapter work for powering gridseeds? I have around five 12v 10a laying around and it's silent unlike standard gridseed PSU. Will they work to power 8 units each? Won't fry them or something?
Each GS miner requires about .75A for scrypt and 7A for dual mode.Any regulated 12v supply should work...
Im using a combination of wall-warts and 12V @ 100A HP server PSUs from old G5 servers...

In scrypt-only mode, do you really need so many fans... I'm thinking of using standoffs to connection two gridseeds to one fan. Does anyone see any issues with that?
I took my fan off since I only use scrypt mode... and it doesn't get hot. It actually seems to be hashing faster...

be creative - you can probably set it up lots of ways to get the lowest amount of power and cooling used for scrypt only mode
I'll be toying with 4 of my 20 to figure something out while the other run with their fans for now

Yes, was going to suggest you run it on it's own to isolate which one it is. Let us know if you get it to work! I also had one like you that would not get any accepted shares on scrypt. SHA worked though. Tried everything I could from different mining software to different hosts/controllers and freq's. Tried running it on its own for well over 12 hours but it would never get any accepted shares....and of course the pools wont show it since it is essentially not doing any work.

Try changing the USB cable and/or position on the hub. Plus wiggle a bit with the powercable

GetResult error 7 in debug. Any idea what I have wrong? It is also saying it is looking for a particular block but finding a different one.

you need a monitor initially because it's IP address is unknown and even a scanner cant't find what has not been set.
If you have access to your router you can find the IP on it. Alternatively you can ping around in your IP range, it will respond. Scripta runs SSH on port 7722.
March 19, 2014, 02:51:31 PM
can it be run nohup - so that it can run even when I don;t have an ssh session?
Use screen:
Code:
screen -S miner
"miner" can be anything, it's just a name that you can use later to get back to it. This will give you a new shell. Start cgminer there.
Ctrl-A, then Ctrl-D will exit the new shell and will keep cgminer running.
To verify that it's indeed running in the background use this:
Code:
ps auxwww | grep cgminer
You can now disconnect SSH etc. To get back to your cgminer:
Code:
screen -D -r miner
Or conversely you could just edit the miner_start.sh script in /opt/minerpeon/startup/ folder and replace the existing cgminer string with your path and custom commands.
With the updated info saved your config will be retained and automatically loaded everytime the RPI starts up (which can be handy if you experience a power loss or the RPI crashes/reboots on its own).

I grabbed a TV and hookup it up via hdmi and had it running in about 45 minutes then it went to my always cool and dry basement where the mining equip is located. I give mine a static ip so after a reboot I always know where to find it.

That is incorrect. By default the Scripta image uses DHCP and its actually quite easy to find the device using angryip scanner (http://angryip.org/)
Be sure to use the proper SSH port 7722 when connecting!

Ah cool, that sounds straightforward. Thanks
