Title: 4x gridseed blades and bfg miner only mines from one gridseed unit Post by: misterblobby on January 19, 2018, 06:08:51 PM Hi, folks, tried to sort this out myself but no joy...
I have 4x gridseed blades using bfgminer, linked by a 7port usb hub on windows 64bit laptop. It to only mines from one gridseed and I have tried different hubs, laptops and bfg versions and all though all the gridseeds register on bfg, it only mines from one of them. They are all working and I've tried different ports and different units yet only mines from one of them. See enclosed picture. bfgminer.exe --scrypt -o stratum+tcp://litecoinpool.org:3333 -u xxxxx.1 -p 1 -d gridseed -S gridseed:all --set device-options=baud=115200,freq=850,chips=40,hotplug=5 Is it a windows problem? https://imgur.com/2jKrRH3 This is freaking me out.. TIA Title: Re: 4x gridseed blades and bfg miner only mines from one gridseed unit Post by: misterblobby on January 20, 2018, 01:09:19 PM anybody help please?
Title: Re: 4x gridseed blades and bfg miner only mines from one gridseed unit Post by: integrale on January 20, 2018, 03:40:24 PM 1.) freq to high for the 40 chips blades , would recommend max 700 , because there is a difference to the 5 chip device in the Voltage regulating section. (own expirience and research on the web).
2.) try not to use hubs , some of them cant handle the amount of data wich want pass. 3.) some info in the link below. https://www.eyeboot.com/how-to-setup-gridseed-dualminer-scrypt-sha256-asic-usb-miner (https://www.eyeboot.com/how-to-setup-gridseed-dualminer-scrypt-sha256-asic-usb-miner) or ask Mr Google hope it helps you a bit Title: Re: 4x gridseed blades and bfg miner only mines from one gridseed unit (FIXED) Post by: misterblobby on January 21, 2018, 02:04:03 PM Many thanks integrale. You are a gentleman and a scholar. The problem is one of power supply. I independantly wired each power cable to 12v supply and that has cured it... they are still set at 850mhz. Hashrate all boards around 2.4mh/s I will change to 700mhz and see if any difference....

powersupply should be at least 6Amps@12V works fine with , per blade of course on my devices i have set to 725 Mhz runs stable for weeks Happy mining Mate |
