Latest Optimized CGMiner Configuration for Gridseed Blades!

Well, just wanted to do a short update on optimizing the Gridseed Blades a bit more.

I found that you can actually run these Gridseed Blades at 850Mhz just fine, there’s some more hardware errors but hashing is a bit faster and getting around 2.879Mh/s per blade.

Here’s my cgminer.conf file:

"pools": [
"url": "stratum+tcp://us.clevermining.com:3333",
"user": "1NqW6oZ5bvLPjWfr6DrzUhLF8X9iLA7TVW",

"user": "DKvhL9zroRNV7D683ze1BRFQdWSw3KhXw6",
"pass": "123123"
"gridseed-options": "baud=115200,freq=850,chips=40,modules=1,usefifo=0",
"hotplug": "30",
"worksize": "1",
"kernel": "scrypt",
"thread-concurrency": "50000",
"lookup-gap": "0",
"gpu-threads": "2",
"queue": "0",
"scan-time": "1",
"expiry": "1",
"auto-fan": true,
"scrypt": true,
"api-listen": true,
"api-allow": "W:",
"api-port": "4028",
"kernel-path": "/usr/local/bin"

I found that these Gridseed Blades run better with 2 GPU thread and a high concurrency of around 50000 as you can see here. Not sure exactly why but they do seem to hash a bit faster with higher thread concurrency. If you have better optimized settings, don’t forget to share it with our users by using the comment box below!

      dtbartle doesn’t report the megahashes correctly for Gridseed Blades, JMoridca is the one that has it fixed.

    1. Max Lee Post author

      It’s great, the megahashes reported are usually right-on or slightly less but the payouts are pretty good, always above average. Highly Recommended. http://CleverMining.com Pays in bitcoins. Oops I sound like an ad.

        Cheers Max. Quick question. I have been running the above config for a couple of days. In the last few hours the M/he rate has drop to 4.6. Is there a way to keep it up at 5.2? http://clevermining.com/users/18psPZLRXvZwsyTS75vzutAE7ov8cEUyVL

        Cheers Jamie.

        1. Max Lee Post author

          Check your rigs and make sure you are getting full 5.2Mh/s, also check your WU rates on CGMiner also if you graphic rig.

  1. Mark

    Hi Max, what would I be getting for the WU value? im getting around 1.5/m is it normal. its showing 2.878 Mh/s per side of the blade but on the pool side its showing maximum 4.2 Mh/s. Do you think there’s an issue with the blade?

    1. Max Lee Post author

      Optimized, you should be getting around 4.5/m for WU value although it’s not super accurate. Raising it will def. help hashing power.

      Are you using the configuration on this page?

    I am currently running 3 gridseeds on a raspberry pi and just received a Gridseed Blade. I want to run the blade as well as the gridseeds on the same raspberry pi. Is that possible and if so, how would you configure the cgminer.conf file to do this?

    1. Max Lee Post author

      You will need to run two separate instances of two different CGMiners. It’s gonna be a bit complex to explain here but I don’t recommend that, just run them on two separate Pis as it will be more stable.

    Fan went out my blade after two weeks. I called about returning it and I’m not getting any feedback therefore I thought I would reset everything back up. I’m seeing 2.8Mhs on each blade. Accepts are staying at 0 and Work Utility is 0. I’m assuming the blades are fried. Does anyone have any comments with the exception of RIP?

  4. Mark

    I’m pretty new into mining and bought a G-blade. What should be normal WU rates for my blade running at 800 MHz?
    I’m getting values of about 2.2 – 2.7 per blade. Does this looks like normal values? I don’t use a config file just a bat file.

    First let me start by saying this has been a great help. I’m use to bfgminer and cgminer but my g-blades came with ready to use cpuminer from zoomhash. I can NOT stand cpuminer. “sudo screen -ls” “sudo screen -x xxxx.x” can not see all the screens on one screen. It was great to see cgminer for raspberry pi. I wish I found it sooner.

    I do have to say that cpuminer was getting me 22MH on a Multipool but when I got cgminer and used this config I was getting 16MH. cgminer stated that I was getting 23MH + but the HW rates where high. You stated this in this post. 850 MHz is what I’m use to with cpuminer but I just changed this posted config file back to 838 MHz and I’m getting 22MH with little to no HW on my multipool.

    Here’s what I change in this config file.
    Everything else is the same.

    Hey Max,

    Actually I owe you a world of thanks for putting this together in the first place. cpuminer was way too frustrating. It’s nice to be able to see all my equipment running on one screen again.

    Thanks bro for helping noobs like me get a handle on mining crypto currencies.

    1. Max Lee Post author

      Yeah exactly, I detest cpuminer, it’s a piece of crap software, cgminer is so much better you can actually SEE your hashrates plus more API features.

  7. VQP2000

    Just bought a blade on EBay. Set it up with the config you suggest here minus some api lines which seemed to cause an error for me. I can’t get more than 600Kh/s per board from the thing. I’m not sure if I got a dud or if there’s something I’m missing in the setup. any thoughts?

    high max!

    your step by step setup guide really helped, but now i a have a problem,
    i have 2 blades on my raspberry mining. but one of them has a power mod to get more m/h and now i need to config the Hz rate for every blade, can you help me ou

    hi there! , I really like a person’s crafting hence considerably! promote many of us be in contact additional approximately this page about AOL?
