can anyone tell me what I could use to connect 8 Gridseeds to 1 connection of the powersupply
it's the questionmark on the diagram

does it matter that the load is not spread completely even? 9 gridseeds / 9 gridseeds / 8 gridseeds ?

Also: if any stupidity is found in that diagram, please let me know  

thanks

We still haven't had anyone test these to see if they burn up or not: http://www.amazon.com/gp/product/B004EAHJAG/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=AXGABATFHDOZ

EDIT: THESE WILL BURN FIRE BAD IN DUAL MODE.

So the outside of the plug should be connected to the white cable, which in turn should be connected to the -V of the powersupply

so normally putting one probe on the outside (sleeve of the connector) and the other at the end of the white cable gives me a reading on resistance
putting one probe on the inside of the connector and the other at the end of the white cable gives no reading
?

Technically it should be "ground", not "-v". There is such a thing as negative voltage. But, if there are only two options: "+" and "-", then "-" is correct.

You are testing for "continuity". So, when you say "no reading", you have to be more specific. If the probes are touching nothing, then what is the "reading". That should also be "no reading", or no "continuity". If you touch the inside (which should be +) to the white (which should be ground), and you get no change to the reading, then that means there is no continuity, or that they are not connected, which is what you want.

If what you mean by "no reading" is that you are getting zero ohms, then that means there is continuity, and that is what you do not want.

I test continuity first - to make sure the cable is constructed the way I think it should be (the component is correct). Then I attach it to the PSU (but not the miner), and test voltage at the plug. That confirms the "system" is correct (did not wire it incorrectly to the PSU).

miaviator set me straight with powering my gridseeds with one CORSAIR Professional Series Gold AX1200

and cables ordered from startech

I'll be able to power a whole bunch of these little buggers...

Do you have the link for the cables on startech site

Found it but from Amazon directly (free 2 day shipping). Just getting the PCIe 6 pin extensions and a bunch of barrel plug adapters.

CX600 only has two PCIe connectors, so can power 6 gridseeds there

That means I need to get some molex connectors too

Question: I know CX600 can run scrypt only safely. What about SHA only as well combined mode (pushing my luck )?

How many gridseeds?

A total of 10. I know I really should use RM1000 or AX1200 (have both, but they are running me ants :p)

Don't do dual mode or btc mode with 10 on a  600w supply: look at  Part 6: Power Usage & Temps https://bitcointalk.org/index.php?topic=494625.msg5448817#msg5448817

I guess with my 1,200 watt unit I should be ok then.

as long as I don't overload any of the 6 PCEI plugs

can anyone tell me what I could use to connect 8 Gridseeds to 1 connection of the powersupply

The ? is a "bus bar". Something like this:
http://www.amazon.com/Blue-Sea-Systems-DualBus-Terminal/dp/B000K2K6M0
The wire from the PSU to the bar should be heavy guage (low number, 12 should work, 14 might) to carry all the current.

Or, you can use a heavy gauge wire to the "?", and join all the wires together (soldier them). If the joint is getting too big, then daisy chain off the heavy gauge wire (connect two pieces of heavy gauge wire and, say 3 gridseed wires, at one connection, then repeat - with one end of the heavy gauge wire going to the PSU (or prior joint), and the other end of the wire to create a new joint. Kind of like how a PSU puts 3 molex connectors on one wire.

does it matter that the load is not spread completely even? 9 gridseeds / 9 gridseeds / 8 gridseeds ?

9/9/8 is close enough for balance.

bobby is using a similar bus bar to do the same thing:

If "no reading" is zero ohms, it's a short, in other words your "inside of the connector" is connected to the white wire. That's probably not what you want.

To test it touch the multimeter probes together, you should get 0 ohms (or very close to 0), that's what you are looking for in your wiring.

Some multimeters have continuity mode, which basically is a beeper/buzzer for exactly this purpose. Use that if you have it.

Thanks, going scrypt only for now...

I hope someone can help, so I have a problem with cgminer that I cannot find the answer to anywhere.  I want to install two versions of cgminer on my raspberry pi, one for my dualminer usb sticks, and one for the gridseed 5 chips.  So the problem is that whenever I compile a different version of cgminer, the other version stops working.  If I open one version, run the miners, then compile the second and run that version, everything is fine.  But when I have to stop or reboot cgminer for either, only the latest version of cgminer that I compiled works?  It is probably something dumb that I am missing that is causing the problem but I can not find the answer anywhere.

Any ideas?

Try running them as different users?

Cgminer makes a ~/.cgminer directory which does something while cgminer is running.

Is there anyway to designate a different folder for cgminer so they do not screw each others settings up

Use
cgminer -c /path/to/config.file
to specify the correct file for each cgminer.

In the config file use
"usb": "1:1,1:2,..."
to specify usb devices to use for each cgminer.

Use
cgminer -n --usb-list
to see the device numbers you should use (Bus 1 Device 6 means you'll add 1:6 to the config file)

So if anyone else is having this problem trying to run different versions of cgminer, I have figured out the solution to the problem.  How I went about it was changing the name of cgminer in the /usr/local/bin directory.

Code:

chmod 777 /usr/local/bin

Then change one of the cgminer files name, I named one cgminer1, then in your .sh file instead of the first line saying cgminer, change it to whatever name you gave the file in that directory.

Code:

cgminer1 --scrypt -o URL -u USER -p PASS

So everytime I hook more than 100 gridseed 5-chip devices to ubuntu 12.04 using the forked cgminer 3.72 (for gridseed) I get errors in syslog about usb.

Some look like this: err (28) No space left on device usb

Others look like this: unable to enumerate USB device on port

I tried another PCI-e usb card and could only get 22 on the extra usb card.

Is there some type of bus limit I can increase to get past 100?

Thanks for any help!

[kbocek]

It's positive center. Use a multimeter to check your wiring, don't rely on colors.

+12V is center. Got it. Good point, don't rely on colors. I know they'll buy and use whatever. I can definitely meter out the cable before wiring it up.

Thank you suchmoon.

If you have enough for a 100 units, get some more controllers... Its better anyways since it gives you another point of redundancy...

Get 5 Raspberry Pi's - 20 units loaded on each one, that way if one miner is down, you'll atleast know where to look instead of finding a needle in a haystack

This doesn't scale well though. I'll have 1000+ of these miners soon and won't be able to manage that many raspberry's..

Any other ideas?

Not exactly that difficult if you know what to look for...

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.

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:
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!
Peace

I take this isn't like the old GPU limit thing and it's an unkown to a lot of people?

If you don't have any automation software you shouldn't run 100 of these.

It's just idiotic to think that you should run 30+ mhash or 100+ devices on one system.

Spread the control out to 10-64 per control system and develop some automation tools or use the ones I post all over for linux.  



chanberg - it's easier than groups of 20 if you label the equipment.


jmordica - Stop being an idiot.

If you are really really planning to run 1000+ of these devices with no automation, no labeling, and generally no clue I hope they catch fire.

Stick 10-64 per control system because that leaves room for a margin of error and for known statistical events of computational error.

LABEL the cables (power/usb) and the gridseeds with the serial number.

Run reports continuously on which devices are up and which are down.

It's just like IBM doesn't make a datacenter and just throw computers into it. They label the rows and cables, and computers.

What's wrong with you.

Code:

./cgminer -n --usb-devs

ls -la /dev/serial/by-id/*

ls -la /dev/serial/by-path/*

lsusb -t
