Is anybody else's "Accepted Shares" on cgminer not matching pool data?

Hashra emailed me today:

11:20 AM (6 hours ago)

We are just about to upload a new img onto hashra.com/support in the next 12 hours.
This sorts out some bug fixes, maybe better to use that one if you can.

Also please make sure you update the firmware for when using for the first time.
Just click on "UPDATE CONTROLA".

I'm using standard cgminer.

Have a question...would it be possible to inline a small power switch to the black fan wire?

I was thinking of inlining this switch on the black fan wire so that I can turn the fan on/off as needed.  

https://www.sparkfun.com/products/9609

Thoughts?

Yes there's no problem with it, except that you need to safely isolate the switch pins since they will lie near or in contact with the aluminium fins

What about a lump of hot glue on solder points to prevent contact with the heat sink?

What would happen if the wires from fans do touch the "body" of the miner? Or are not isolated well enough after fans have been cut.

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
https://i.imgur.com/y2f1pwL.jpg


Here's the command line options to run cgminer:

--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...

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.

Yep that sounds exactly like what I have here. Will keep you posted if I figure out something.

I'm going through the same exact thing now.

Did the new firmware help?
Do I _have_ to use a power connection or will USB provide sufficient power?

Just flashes green with no accepted shares, DOA?

[maxzilla]

I could really use a tip here. I have followed the instructions or lack of and am still not able to view the interface. I'm sure I'm missing something . . .

I have the latest firmware for the raspberry pi. It boots up to a command prompt that prompts for

hashracontroller login:

then password.

I cannot find the default settings anywhere in the manuals or online. Can someone please help me out here? Am I doing something wrong?

Thanks in advance!

Fyi, using the controller I'm running at 3.0
3.6 would be nice

If i where you, i would use user:pi pw:hashra  

Thanks, I'm curious . . . Where did you come up with that? Lucky guess? Should I have known, lol?

Just trial and error.....  

  That worked! Thank you very much. I'm still not able to view the interface though after following the instructions in the manuals or lack there of. After logging into hashracontroller command prompt I see this screen. I have tried re-booting and removing the line from the text file that I added to change password.

What am I doing wrong?  

Do I need to install Raspian from Noobs before writing the hashra image file to the disk?

Thanks!

you have to go to the controller with your browser
or if you like ssh view type this in

Code:

 sudo screen -r SCRYPT 

to see the underlying miner running.

The Desktop is not installed on the img, to save space and performance

So, how exactly do you remove the fan wiring? Did you just cut the wires, or de-solder?
What's the best approach?

You running off the PC or Pi?

Would love to get the Pi working but it's unstable...at least for me with 20 miners

We have 44 running on one pc running Ubuntu currently. Running for a few days with no issues so far.

Obviously it's better to desolder the wire, you can sold back again when you want to use the fans or sell the gridseed.
If you are in hurry you can cut the positive, but instead of leave the two end isolated connect them to a switch

Could be an easy fix but keep in mind that hot glue over 45-50°C start to get soft...if the miner reach that temp could melt the glue

Anyone getting full speed out of the grids on windows with BFGminer?

Currently running 9 of them:

3.4 / 3.41 / 2.09 <-- this is the number matching the pool hash....



Thanks for any help

What's your definition of "full speed"?
Im running 5 at 850 Mhz on Windows and another 10 at 800 Mhz on Raspberry PI. Ive seen someone get 1000 Mhz in a picture, but had HW errors.

By full speed i mean is anyone actually hashing at 380 per unit....on windows/bfgminer   it seems the actual numbers are around 220khs  seems to me any sort of overclocking atm slows the process ....i went back to 850 and left it....now at 2.6Mhs for 9 units....

Hello.
I tested the results of my mods overnight and, so far so good!
I decided a couple days ago to go ahead and try modding one of my pods.
I made the first mod which is to jump the two resistors as shown with the yellow stripes. Done deal.
I got a bit better performance out of it @ 900MHz and 950Mhz but still pulled a red nonce every once in a while and at times they would fill the window (cpuminer) for a short birst then go away.
I thought "how strange, what is causing this? Could it be a timing issue?"
Bingo!
The guy who did the mods and had his GS5 running at between 1000 and 1100MHz stable but with a few red nonce's gave me the tip...
I thought, let me try the pencil mod.
So I tried lowering the PLL voltage first to around 1.01V. Seemed to stabilize running at 950MHz so well that I only saw a red nonce every great once in a while over an hour or so of operation where before it was about 3 times as much.
Okay, so changing the resistor was next.
I changed out the 36K for a 38K 5% resistor.
BINGO!

Now I have stable 'no red nonce' operation at 1000MHz!... It's been running stably for over an hour now with ZERO red nonce's! Perfect!
I'm going to let it run overnight and see how things are in the morning. I have a good feeling this is the trick I was looking for.

Thanks to the author of this mod!

I'll save further congrats for later on if I see stable operation over time.
Oh and one other thing. I decided to go ahead and test my theory that lowering the voltage of the cooling fan to 5V was not a good idea due to the usual problems associated with magnetic DC motors.
I guess the drive electronics of DC fan motors has come a long way since I last farted around with them years ago.

I'm driving it with 5V now without any problems so far. Runs just fast enough to keep air moving at a good enough rate to keep the unit cool to the touch! I mean below 90*F. More like 79^ to 81* currently.
And man, it is quiet! Music to my ears! The pod was cooking at 115 to 120*F at 1000MHz which is understandable. That's crankin, for this little bugger!

Not running hotter or pulling more current like I thought it would, at all.
Sorry for scaring some of you guys out of trying it but I guess I get to make up for it by risking burning up my fan etc.
I'll let you know how that went overnight too.
I will also attempt to run it off of the 5V USB power next and see if it screws anything up comm wise or power wise.

It's pulling less than 75mA running. Pulls 140mA start up for a quick second before it calms back down.
I think it would be easy enough for most folks who end up doing this mod, provided mine works out okay, will be able to compensate for the additional load it puts on USB power. But it's a short cut method I really don't recommend in general. One should use a voltage regulator to drop from 12V to 5V. There is more headroom on that rail too in most cases.

Today I'm going to monitor the performance of my 1000MHz hasher for stability and expected increase in pool results as well as connect the fan to the 5V rail of the USB port and see if it causes any problems.
I don't think it will but if worse comes to worse, I'll use a 7805 voltage regulator to drop to supply the 5V from the 12V rail.

Onward!
Peace

And a stupid question - what do red LED's mean? (green are power, correct?)

[wolfey2014]

And a stupid question - what do red LED's mean? (green are power, correct?)

Hello everyone!
This data will definitely help with Tuning your GridSeed 5 chip USB miner/s.

I just received this data from GRIDSEED via HASHRA.com today. 3-13-14
I'm paraphrasing for general clarity.
I've also added some of my own observations based on direct experience with my own GS5's.

GRIDSEED GS3355 5 Chip USB Miner - Flashing RED and GREEN LED's - What They Actually Mean.

All timings are either approximate or exact, if not darn close!
Your clock speed may vary slightly. Wink

GREEN flashing LED means - 5V is ON / drive electronics are powered up.
GREEN LED is ON for 1 second, OFF for 1 second.

RED flashing LED - ON 3 seconds / OFF 3 seconds / Flickers:
Miner Is Hashing / Processing Data.

RED flashing LED - ON 60 to 70 seconds - OFF 60 to 70 seconds:
Miner is Not Hashing / Processing Data.

If Fan is OFF and RED LED IS STUCK ON or OFF i.e. not flashing:
12V is OFF - 5V is ON.

FAN is ON but no GREEN OR RED LED's are flashing ON or OFF:
12V ON - 5V OFF.

When first powering the miner on, the best sequence I have found is:
First, turn 12V Power ON
Second, turn 5V USB Power ON
This will enable self test to occur in correct sequence. (I'm guessing)
If you do not use correct power up sequence, various hash / no hash / no shares reported type problems may occur. (I'm guessing here too)

A few seconds after 5V USB Power is turned on, the GREEN LED's will start
to flash ON/OFF as written above.
After 12V power is turned ON, in about 60 to 70 seconds,
the RED LED's will start to sequence ON/OFF as written above.

Hope this helps!

Depends also on the pool. Which pool gives You 2.09?

BTW non-moded (yet) gridseeds pushed to 850 frequency...
....and yeah, I allways loose at least two Dualminers during weekend because I'm not near them to replug. I should consider using scrypt someone prepared for "soft replugging" Gridseeds. Actually, Dualminers are crying for something like that, not Gridseeds.
