Download the latest cgminer 3.7.2 with Support for Gridseed GC3355 ASICs

13 May


There were some requests from readers to provide a compiled binary for windows of the latest cgminer 3.7.2 with Gridseed support based on the jmordica fork, so we have compiled it. The most notable difference from the previous compiled version of cgminer we have posted with support for the G-Blades (also present here) is the addition of support for NiceHash service where you can now also use your Gridseed ASICs to sell your hashrate. The supported frequencies range from 700 to 1400 with finer grain selection available, for the complete list of supported frequencies you can check the readme file. Below you can download the windows binary, you can change options by editing the config file.

You can download the latest cgminer 3.7.2 with Gridseed ASICs support on Windows OS here…

It says on NICEHASH website that:


Popular cgminer 3.7.2 is not supported due to the bug in the code. You have to use newer miner.

So does this work? I’ll try and see.

This is the latest version of cgminer for Gridseed you need with support for Nicehash:

It just rejects all the shares saying, “invalid extranonce2 size.”

Ok so I installed the WinUSB over the STM32 Com driver, but now it just keeps saying “Stratum from pool 0 requested work restart”.

Finally, I got it to work. I had to run cgminer, unplug the USB cable. Plug it back in, restart cgminer and boom it works.

I use this version to correctly display hash rates on my blades then I have a separate RBP to run my 5 chip singles. I know you can set it to 40 chip or 5 but as far as I can tell you can’t do both or set it per serial number like you do speeds. It would be great to be able to and I could literally just run them all together. I do know they will run together and work fine according to the pool rate but I’d like it to display correctly all together in cgminer.

Just keep in mine if the dev sees this.

Hi, I am using some Gridseed 5’s.

I have noticed that if I use dual mining mode, both sha for bitcoin and scrypt for Litecoin,
I can not change the frequency via the bat file parameters.

This line below is for 2 GSD’s on WinXP with cgminer-3-8-5-gridseed-windows

cgminer.exe -o stratum+tcp:// -u myusername.myworker01 -p –gridseed-options=baud=115200,freq=1350,chips=10,modules=2,usefifo=0,btc=16 –hotplug=5

It makes no difference if I put in 600 or 1350.

Is there anything around that allows me to change the frequency while I am in DUAL mode mining?

I have scowered the internet for this but you have to build it, here is a compiled raspberry pi image with CGminer installed config by pc, mining pools, logs, not perfect but been running for weeks. It is 8GB chrome://mega/content/secure.html#!RN5QmQxJ!AzeyJbz7gRLc4tWyVgnD_S6FMJ8iYvxLHQrCbqfvLCE If this is useful to you plz 16vW4zXwAtJqG5WsURYNhvGSSQRgD2c4dw btc thank you

I give up.. this is a hopeless machine and clearly flawed.

I cant seem to get more than 4 blades running?

I’m in trouble. Please help me. Thank you.
I have a Gridseed 5-chip GC3355
solo mining use the cgminer-3-7-2-gridseed-windows
The xxx.conf file >>>
A coin:rpcport=8333
B coin:rpcport=8332
The xxx.bat file >>>
A coin:cgminer.exe –scrypt -o -u a -p b –gridseed-options=baud=115200,freq=850,chips=5 –hotplug 5
A coin:cgminer.exe –scrypt -o -u a -p b –gridseed-options=baud=115200,freq=850,chips=5 –hotplug 5
When solo A coin, the cgminer works fine.
But when it comes to solo B coin, it’s an error “Pool 0 slow/down or URL or credentials invalid”
