i`ve managed to compile it, it runs, it detects all the gridseed devices, it seems like they are hashing but they don`t find any share at all

any ideas ?

Have you tried different pools? Some scrypt pools have different addresses for high diff and low diff (high is usually 1-2 MH/s) miners, and if you're at a "high" one you might not be able to get any shares.

I ran into this issue too. Don't use high-diff servers for a 70 or 300 Kh/s device.

Also from your output it looks like you only ran it for less than 3 minutes. Try giving it longer so luck has time to play out. Also try just one server. Trial and error will help here since it works well for others.

What server (pool) are you using or would you recommend? I am bring up 40 Gridseed (5 chip) miners up on Bfgminer tonight, want to be as consistent as I can.

Did you have to load any drivers for BFG to see the Gridseed units?

[ManeBjorn]

I use LTC Rabbit.
https://www.ltcrabbit.com/#afkun1

They have a solid pool with an altcoin bonus when applicable.
The other that is good is Scryptguild.com which is currently in beta.

I hope it helps and Happy Mining.

So no drivers to load on a Windows machine to have them recognized by Bfgminer?

Thanks for the pool list, I will try them tonight

if I plug the units in that crappy controller they spew couple hundred frames in 2 min mining on the same pool. Even that cgminer (which locks up the pi) spew shares almost instant.

anybody care to share the file (i`m runing arch linux on a Pi)

Windows found my DualMiner with no issues.  I did already have this driver pack installed though.  These are the correct base drivers for many USB ASIC devices that would be run on BFGMiner.

do you think overclocking the GS units is worth it? Do they get hot and could that be an issue re the non-acceptance?

Trying to work out getting my cube to work with BFGMiner instead using the proxy.

Read through quite a bit of stuff on here and figured out that I don't have the --http-port command available in my 3.10 build (windows 64bit). When I try to execute the command it says --http-port option unrecognized.

Cube is up and running fine with the proxy but like the display and statistics of BFG better.

Any suggestions? I hope I don't need to manually compile some version just for this as I thought it was built in as the ReadMe.txt file has it as an available option.

Run the 32-bit version. You don't have to run the 64-bit version on a 64-bit OS.

Thanks for your hard work Nwoolls and Luke-Jr

I am running the gridseed-dualminer-support branch on my Pi, and everything works great.  Only problem was cloning that branch I kept getting 403 errors, so I just download the zip from the site.  Compiling it I had to git clone the bfgmaster source, delete the files from the master, and move the files from the gridseed-dualminer-support into that directory in order to rund Autogen.sh.  After that it compiled fine and I am able to run my 4 gridseed 5 chips, and 16 dualminer usb sticks in one window.  I am not sure if the gridseed 5 chip I was able to overclock to 850, I used the --set-device gridseed:clock=850 ? It took the argument but the hashrate is about 10kh/s lower that with freq 850 in cgminer. 

Thanks again

[Eldoen]

on the Gridseed support, is the Scrypt only support turning off the Sha side of the chip.

The options I would like to see supported is
Scrypt only turn off the Sha part of the chip. when running in Scrypt only gridseed should pull no more than 7 to 9 watts.
I know the original CGminer SHA was on even though it wasn't being used.

Sha Only, which at todays difficulty would be a fools goal but to each his own.
Dualmode.

Will see what I can do to compensate.

Thanks El

Are you saying that when scrypt only mode is enabled the sha side is still on?

yes on the original build of cpuminer(sorry stated cgminer above) the sha part of the circuit was on and pulling power.
a new build that only runs Scrypt, turns off the sha part of the circuit and runs at a much lower draw

Haven't tried bfgminer yet since the 5 chip Gridseed has been added on a beta build?

I would assume it has to be... SHA2 is part of scrypt, after all..

When using 20 gridseed I was getting maximum of 2mhs, when using cgminer I'm getting 7.2mhs. Also noticed cgwatcher only reporting on 1 gridseed

For some reason there seems to be a huge difference in performance between bfgminer and cgminer-gc3355.


Here are 10 min runs, the only dif in setup is the miner used:
- watch the total accepted shares
- watch the HW errors on bfgminer
- watch the spamming message from stratum

Maybe a fairer test would be between CG 4.0.1 and BFG 4.0

You are missing the point of my post.

I`m trying to compile bfgminer-gridseed-dualminer-support for raspberry pi but it behave poorly compared it with cgminer-gc3355 (official cgminer removed scrypt support after 3.7.2).

Run the 32-bit version. You don't have to run the 64-bit version on a 64-bit OS.

Tried that one and it returns no devices found and "failed to start HTTP server on port xxxx"

Not sure on the other two but you cannot compare the A number in BFGMiner and CGMiner. CGMiner weighs their stats with the difficulty of the server. Try running both for the same amount of time (I'd say at least 30 minutes) and then hit Q. Both will report the number of shares submitted to the server. That should be closer, as long as they are both running against the same server with the same difficulty.
