Hi all,
TL;DR;
My Gridseed works erratically.
Works with GiveMeCoin always getting Accepted shares, but with low Hashrate (max of 70Kh) running for 8hrs
Works with WeMineLTC intermittently. sometimes my Gridseed Accept shares, but a lot of times, it's not doing anything
I have tried CGMiner as posted and to the letter (with Zadig) but crashes
I have tried MultiMiner, but it wont detect Gridseed
More Detailed Description of the Issue and Troubleshooting DoneI am having some problems with Gridseed 5. I got one for test drive and have created an account at WeMineLTC, and downloaded the wallet at the official site, and has fully synced. I've had my Gridseed for a day now. The GridSeed is directly connected to PC USB2 port (i.e. no hub)
At first, I followed this guide to try dual mining SHA and Scrypt:
http://cryptomining-blog.com/1711-updated-guide-on-how-to-mine-both-btc-and-ltc-on-gridseed-5-chip-gc3355-asic/I can't even run CGMiner because it says I need to install a USB driver. Which I already did, using Zadig and double checking using Zadig "List Device" and also under Windows Device Manager. Mine is STMicroElectronicVirtualComPort(COM5). I made sure I took note of the COM port (COM5) and edited the batch file and made sure that COM5 is reflected. But everytime, CGMiner will crash and will not proceed. I have tried 3 versions of CGminer and downloaded the latest versions (as found on the first post). Note that I have tried CGMiner both at the native STMicro driver and Zadig WinUSB driver.
So I ditched the idea of dual mining and just focused on Scrypt mining.
So I used MultiMiner, but no dice. Even if MultiMiner can detect my AntMiner U2, it can not detect Gridseed (I have seen posts in Nwool's GitHub about how the gridseed works). Asking and posting at GitHub has no reply. And just like with CGMiner, I have tried MultiMiner both at the native STMicro driver and Zadig WinUSB driver. So...I ditched MultiMiner.
I went to BFGMiner 3.99 and lo and behold, it detected my Gridseed FINALLY, and it went to work. Since it's my first time using Scrypt (and a week in Mining BTC), with DOS-based utility, I struggled to understand some of the display. But eventually, after checking WeMineLTC dashboard and looking at my DOS status screen, it dawned on me that my Gridseed is NOT accepting any shares. Bfg will send request for work update on the server, but it just won't get anything. So I have to, again, use both Zadig WinUSB and going back to STMicro driver, but only the STMicro driver works. So I stick with STMicro.
I checked everything, from username to port to URL. Then for some reason, my Gridseed started to accept share, out of nowhere. I started getting KH on my dashboard. But, there will be a lot of time lapse where I won't get any share (I figure I'm just getting bad pool) but nope, I waited for 8hrs and my hashrate went down.
A few reboots, and a few reconnect later, I get random share acceptance so I decided to try joining GiveMeCoins.
Now this new pool (GiveMeCoins), I get regular accepted shares. I am ALMOST happy. I let it run for 8hrs, but I noticed something odd on my web dashboard and my BFGconsole dashboard. My Hashrate never goes beyond 70Kh. I'm supposed to get more than 100Kh, heck, almost 300Kh. With frequency set to 800 (I have seen others set it to 850 and higher), I was hoping to get higher. So I dabbled with it and noticed that Gs0a is being used while Gs0b-Gs0e are not (from the BFGconsole).
I am baffled by this. I can't really tell for sure if my unit is defective, or the pools I am joining are really bad. WeMine won't give me shares, while GiveMeCoins gives me shares but with such low KH.
Any help will be appreciated. I am at the end of my wits here.
System Specs:Windows 7 32bit with all the latest service packs, no bangs, no whistles, plain old OS
No other software, no antivirus, no firewall except for Windows default firewall (no Essentials)
I have 2 AntMiner U2 connected to it, via USB Hub, working and hashing happly, using MultiMiner (CP uART driver)
I have 1GB RAM
Atom 2Ghz CPU
Gigabit Internet
45Mbps Comcast Internet (speedtest on mining rig shows close to it)
64GB SSD for storage/boot/applications
Gridseed directly connected to USB2 port of the PC
My BFG for WeMine is written as:
bfgminer.exe --scrypt -o stratum+tcp://power.wemineltc.com:3333 -u weminedead.1 -p x -d gridseed -S gridseed:all --set-device gridseed:clock=800
I also tried other pools at WeMine
bfgminer.exe --scrypt -o stratum+tcp://usa4.wemineltc.com:3336 -u weminedead.1 -p x -d gridseed -S gridseed:all --set-device gridseed:clock=800
bfgminer.exe --scrypt -o stratum+tcp://usa4.wemineltc.com:80 -u weminedead.1 -p x -d gridseed -S gridseed:all --set-device gridseed:clock=800
As for GiveMeCoins
bfgminer.exe --scrypt -o ltc.give-me-coins.com:3334 -u weminedead.1 -p x -d gridseed -S gridseed:all --set-device gridseed:clock=800
I also tried adding stratum
bfgminer.exe --scrypt -o stratum+tcp://ltc.give-me-coins.com:3334 -u weminedead.1 -p x -d gridseed -S gridseed:all --set-device gridseed:clock=800
If you guys have any suggestion or seeing what I am probably missing, pls let me know. I haven't tried running the Gridseed on other computers though, so I am still not ruling out my slow CPU as the problem, I never tried on other PC because I have seen others run Gridseed with much simpler host (rpi, etc).
