Topic: [GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning - page 41. (Read 308807 times)

OK, looks like im going to stay on Sandor cpu miner with my 80 miners.
I wonder how is the most efficent way to run them. Perhaps 10 per miner and worker? Or is there any difference at all running 10 per worker/miner or 20 per worker/miner?
Perhaps someone has more experience to share regarding this?

I haven't seen this anywhere but is there a benefit to raising the 'baud rate' of the gridseed port above 115200?

OMG, LOL! How'd you catch that before I deleted it...

Here are my results of using sandors cpuminer. You can see a much lower (perhaps over half) DOA/stale rate:

Cartman is right. cpuminer is superior to cgminer, obviously, as it forked from cpuminer in the first place ;p!  

No, really. I have only ever stated how much I LOVE cpuminer and anyone using it will surely agree, especially now since Sandor111's recent upgrades to it at the request of several other users on here who also feel it is the best of all the other programs.
I am entitled to my opinions and assertions etc.

It is clearly up to each individual to make up their own mind, of course! I mean after all,  it's only a natural inclination, anyway! Right?

But, in my opinion, if you decide to just trust and go with cpuminer, you will have made a great if not perfect and totally 'safe' first time decision! Especially if you are a noob! Trust me on that!

As to the rest of Cartman's comment, 'why, what ever do you mean?' ;p

Yes, thanks. Looks like my previous download was somehow falty.

Oh yea, forgot. Heh...keep up the good work!

I see nothing wrong here, are you using the latest build (https://www.dropbox.com/s/ttqa9p851siz8oi/minerd-gc3355.zip) ?
Could you post the full command line?

I love CGMiner, but the main intention was to build a Gridseed miner for Tp-link 703N/Wiibox, it had to be faster and consume much less memory than CGminer and able to run many (100+) miners on a single instance to combat the limitation of 32MB of RAM, but I ended up adding a lot of stuff to it that I hadn't planned for, for the better.

cgminer works great with gridseeds on Linux! It's the way it handles USB on Windows that is the problem. I switched from Windows because of this. Resisted for years but am glad I did. The learning curve is medium to high though.

cgminer was forked from cpuminer. It has advanced quite a bit and I too feel sandor should be building off the latest version of cgminer with scrypt added back in. He's not kidding when he said he feels like he is reinventing the wheel

That being said I have been using sandors cpuminer for the last day with great results so far!

If you have it compiled then I think you're 80% there. You need to start it:


I'd suggest to use a config file, i.e. cgminer -c config_file_name

If your cgminer is not in the cgminer-gc3355 folder obviously you'll need to adjust the command above. For gridseeds you'll need at least:



Adjust frequency to your liking. Once you get that running, try:


This will run cgminer in the background. Use the following to look at it:


Ctrl+A, Ctrl+d to disconnect

Then if it's all working add the startup command to /etc/rc.local to start it on boot.

I think that's it. If you run into any issues - ask.

Awesome cannot wait to try this out

Yo Sandor!
Your latest cpuminer single pane version (pun intended) / auto freq', is working great!
I finally figured out the cryptic explanation you sent me re: what everything on the green line means which is cool. But based on the order the pods have been assigned their comm port number, it's hard to tell right off the bat which pods are working and which ones aren't. Not without squinting and scrolling a bit.
Could you add a line at the top that shows, 'in order' installed, the pod number that is working in green and the ones that aren't in red ... A line like pod 1-2-3-5-8-6-7-9-0-4... In real time of course
Looking forward to further cpuminer updates and improvements!
Thanks pal!

I have never used linux from terminal, so this is way too complicated for me without guide. All guides i have seen are old and aged.
Somehow i got cgminer from gridseed git compiled but im clueless what to do next.

I haven't tested it with a G-Blade yet, but it should work if the firmware version is the same for all.

Nice work Sandor, when I have some spare BTC I'll send you some to take a beer or two

Support for individual chip frequency is added. It’s possible to run regular USB miners and G-Blades on a single instance, because the number of chips is now auto detected.
Binaries (Win, Rpi) have been updated.
I'm still working on a summary like cgminer, almost done, but it feels like I'm reinventing the wheel.

Trouble switching from CGminer to CPUminer?

I think I figured it out.. thanks to some advice from Pete @ Zadig.

Problem: After running Zadig to get CGMiner working... I couldn't get my Virtual COM ports back to a "virgin state", i.e. to appear under "Ports" section in Device Manager, show a COM number, and allow changing COM number and disabling FIFO buffers etc....

Removing the COM ports from Device Manager and even ticking "delete driver software" when doing so wasn't having the desired effect.

Solution: If like me you'd had the gridseeds (via USB hub or not) plugged into more than 1 USB port at any one time.. then you need to uninstall the STM32 driver (Add/Remove Programs), then plug the gridseed back into every USB port of your PC you ever used them in, systematically, and go to Device Manager each time to uninstall the COM ports that appear (usually under "USB Devices", if you had used Zadig to set WinUSB as the driver). After you've done them all, plug the gridseed(s) back in (I think they still appear under USB devices at this point..) then install the STM32 driver... and voila... back to normal, and CPUminer works.

p.s. with both CGminer and CPUminer I find that I sometimes have to unplug other USB devices from my system (mouse and keyboard lol) before they will find the gridseeds and start mining. Only sometimes however. I can plug them back in after mining starts, without problems.

p.p.s. it would be really great if CPUminer could be improved to show stats at the top like CGMiner does. Also.. as it takes ages to fine tune the chips.. is there any way to store that info or does it have to restart the whole tuning process every time you restart the software? Sandor?

With that number of miners I would strongly suggest Linux and girnyau cgminer. I did a little roundup a while ago, it is a bit outdated now (newer versions of software have been released) but most of it still stands:

I need some help please.

I have 80 5 chip miners. Going to run them on powered hubs and a single PC.
Whats the best OS and miner? Need to be able to remote control over internet (either web control panel or RDP)
Theres lots of guides in forums but i failed to find any guide which has all the info needed. All guides are incomplete in that sense.

If you like cgminer, then try BFGMiner instead (made by the same devs and looks and can be configured exactly the same way), there is a windows build 3.99.0, which runs good
