Topic: [GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher - page 57. (Read 365630 times)

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?

I plan on using a RasPI
bought this hub: http://www.amazon.com/MANHATTAN-13-Port-Hi-Speed-Desktop-161022/dp/B002ZU7HH2

a troublefree road ahead of me?

No problems here!
There are NO firmware issues causing disconnects!...in my GS5's at least.
I'm using cpuminer - works great!
Cheap USB hubs can be problematic but even they can run stably under the right circumstances.
Most that come in plastic enclosures are not shielded from EMI. This can cause issues.
Some are real crap. I'm using Inland 13 port and it seems pretty stable if I keep it away from the miners and power supply which emit a degree of EMI. Any electronic device that switches at high or low frequencies emits EMI (Electro-Magnetic-Interferance)

When my gridseeds were connected to ScrypGuild.com they were failing to find shares after being disconnected from their server - automatically - for what ever reason.
I've since moved to another pool and so far , no problems!

I see so many complaints and configuration issues coming up from cgminer and bfdminer yet, using cpuminer there are no such problems or issues! NONE! Why isn't everyone using cpuminer? I think, based on what I've seen and read, bdgminer should be called BFHminer (big fuggin headache) because it causes so many configuration and coding issues. Why bother with it then? I will say that cgminer seems to be a lot less buggy and most are having success with it. But I see few if any complaints about cpuminer from those who are using it. They seem to be simply hashing away with little to no issues.....me included!

No baby sitting here! Set and forget! Letter-rip and make you money! It's all about producing successful shares and converting it into money you can use! That's it.

While most here probably use cgminer I am still using cpuminer and batch files, very happy with the performance.  I did test cgminer out and it would only show around 20 of 30 gridseeds.
I have all of them clocked at 850Mhz and they will stay running for days without any issue, running 30 on WinXP host, 10 devices per 10 port Rosewill 10port usb hub.  I get a consistent 10.5-11 Mh/sec out of them.

Lets be more specific.  If running from the controller there are a lot of reported issues of hung devices and required device/controller resets.  

I've been running mine for more than a week on linux with 0 intervention.  I'll be racking the devices I leased out in a different thread later this week and will likely not touch them or the computer controlling them for another 3 months.

Currently I have 15 and 16 connected to two raspberry's with the newest scripta with cgminer, the crashpatch and autorestart on. So far one day without touching the thing. Hopefully after the weekend it'll still run.

Sadly yes... unless you buy some reset power devices to cycle them regularly...

I have had mine lock up and require a USB reset (unplug the USB cable) several times in the week since I started with it. Its a firmware thing that needs to be addressed.

do the gridseeds need alot of babysitting? (running scrypt only at 850Mhz)
expecting my babies next week, YAY!

?  Lightening Asic is the name of jacks company which resells the gridseed devices in packages.

sorry for the simple question but what purpose does the lightning asic serve?

in terms of having to be enclosed that is not really trueI have been dealing with hosting dot com for 10 years now and you can put whatever you want in your cabinet

however for co-lo'd equipment in a rack you are correct.

Lol.  As much as I love displaying random electronics in open air settings data centers prefer (require) to have things cased and racked.

16 for me, maybe mor depending on how shipping will be arranged to EU,
I don't want to be sponsoring customs

...but they were born to be free..not hidden in a cage!

There is ZERO reason to be concerned about airflow in scrypt only mode unless your ambient is well above 90 F. The ~8W you burn up in scrypt only mode doesn't even bring these things to a point where you can't touch them while hashing... not even close.

I would be concerned about air flow. how about an open front and  when rack mounting put one of the 3U fan kits in the front of the rack.

Monoprice 24-port hub has 7 ports at the first level, 3 of those connect to 3 internal 7-port hubs. The total comes to 25 ports (4 remaining at the first level, + 3*7 at the second level), not sure where the 25th port is though. Anyway, good news is that Raspberry Pi can access all 24 ports. I have not connected miners to it yet, but tested with a USB flash drive. Will follow up once I do a real mining test.

okay 500watt power supply roughly 25a rail 10awg wire to keep it safe. A power supply delivering at 41amps 12 awg.  That's a lot of gridseeds

15.0" x 19.0" x 3.5" 2U rackmount 15" Depth.



I think there is room for a Pi as well if I cut the power cords a bit shorter.

I could fit at least 30 in a 3U and 20 in a 2U long case based on this catastrophe.

These are designed to be power splicers for low current equipment..  You might be right though.  Looks like most of them are designed for 500ma at 12v power.  So they will likely melt.
