Topic: [GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning - page 46. (Read 308807 times)

I'm still using this binary (https://bitcointalksearch.org/topic/m.5539257) for my Gridseed, every other try with a rasp cgminer binary gave me around 10% less hashrate ...

I tried out this ... but looks bad on the pool ... compared to the one I'm using

https://github.com/girnyau/cgminer-gc3355

Anyone else suffering from that?


I did compile the changed Blade cgminer, which works and shows hashrate accurate for the blades ... chips=40


Rasp Binary: https://drive.google.com/file/d/0B7L0F0oittD_cTV6Rl9OOWVLTzg/edit?usp=sharing


What binaries is everyone else using for the raspberry and Gridseed products?

I see that diameter of gridseed 5chipper is 9.5cm, but could someone please tell me the hight without fan. So i would know how many i can fit in to my tower case.

You can if you plug each blade to a different controller

Have a blade coming this week...can each of the two "blades" be run separately on different miners/pools?  I plan on using hashra with a pi or two.

Actually i am absolute certain its on usb 2.0
The usb 3.0 slots are used up by external drives and other real usb 3.0 devices (I mean by that devices which really deliver speed and do not dc itself on these ports)

On my 5 computers with kinda all versions win above 7 on them 7 ult x64, 7 ent x32: x64, win 8 x64, win x 8.1 funny enough also on the r.pi it acts weird
Changed hubs, changed pc, changed usb cables
I deleted almost all linux partitions because i hardly use them since most miners i had are having almost everything aboard (knc, ant) so almost no fuss power up and go.
Takes me 3 minutes for setup a knc box for mining on any pool, including installing the psu
Ants a bit more since they are a bit slow on the web interface, unless you want fixed ip's then it takes even more time

I am pretty sure its more then able to feed both boards on a blade they are rated to use 100 watt so bot sure what they pull for real since too much extra is needed to let them run

Hey Bronan...

PSU...:
8-pin PCI-E connector is rated @150W max...not 225W...You should be fine here...You could try 2 separate PCI-E connectors...1 for each board...

Software...:
cgminer NEEDS Zadig driver...installed properly...without it it will NOT recognize gridseed...
bfgminer is opposite...DOESN't need Zadig...just opposite...you have to Un-install zadig and put back STM driver...

USB...:
Are you sure that you are NOT using USB 3.0 port(s) on the back of your PC/laptop...Gridseeds are intended to work with USB2.0...they don't like usb3.0...giving us all kind of weird problems...Make sure that both USB cables go the 2 USB 2.0 ports...

Just my 2 cents...

ZiG 

bfgminer allways have report less hash then cgminer does, but i allways noticed that i got less errors with bfgminer as well on my btc machines

running 800 Mhz on the blade gives me about 3 Mh far less then the given 5.6 they posted so i am pretty convinced they started with higher speed as well
running 850 Mhz gives me near 5 Mh at this point, however knowing bfgminer it has to settle a bit longer
I will check the performance on a regular basis so i am sure its not going to pump out high % of errors although on scrypt i allways saw a higher hw error rate.
The problem i have is weird bfgminer sees both boards when i install zadig i get either no devices found at all or it finds only the second board
I can actually turn it off but since the fan is connected on that board, this is not a wise idea. Even though they stay pretty cool i  think without the fan they die pretty sure of heat.
I pulled the cable out several times let it rest for 15 minutes plug it back in but it simply refuses to be found by cgminer
For the power well its connected to my 1200 watt antec on a pci-e connector which should be able to feed 225 watt at max since its actually a 8 pin
So the 140 watt it might pull or a bit more will not even make it sweat at all i think
And second feeding it off a pc psu is more efficient, but ill check it from time to time if things act up weird

I will try to run it on 800Mhz, because they are actually needing from 100W to 120W as they are not connected equally comparable to individual grdiseed miners. More: http://cryptomining-blog.com/1921-performance-results-from-2x-gridseed-blade-miner-asics/

Hey that indeed exact how i did it on the win 7 x64 machine
Win 8.1 seems to have a problem with usb access somehow

I did change the speed to 820 before but it had a weird effect the boards ran slower

bfgminer.exe --scrypt -o stratum+tcp://us.multipool.us:7777 -u me.s1 -p x -d gridseed -S gridseed:all --set-device gridseed:clock=800

Now after i changed the speed to 850 it now runs at 4.6 Mh nice

Anyway thanks for posting the instructions anyhow seems to run ok now

however the bfgminer still does try to start the gpu but since its only a 5450 low profile fanless its not even capable of mining at all XD

does anyone know the command to let the program skip detecting the gpu ?

later i will try to get it running with bfgminer from a pi image but for now i am glad it is running

Hi!

If you are having problems with mining on bfgminer, then you'll will need to do as follows:
1. Go to Device Manager
2. Then Go to Ports (COM & LPT) or Universal Serial Bus controllers - depends what drivers you have installed
3. Delete STM32 Vritual COM port driver (or something simillar) or STMicroelectronics Virtual COM Port (COM1-XY), and choose "Delete the driver software for this device" if available
4. Download http://www.st.com/web/en/catalog/tools/PF257938 drivers
5. Install drivers
6. Download BFGminer 3.99.00 from here: http://cryptomining-blog.com/wp-content/files/bfgminer-3-99-0-windows.zip
7. Run bfgminer with LTC_ONLY.bat in the folder with the following flags:
-d flag to turn off the GPUs
8. Wait 10 minutes to miner really warm up - third row is the responding pool hashrate

If you want to run cgminer, you have to do as follows:

1. Go to Device Manager
2. Then Go to Ports (COM & LPT) or Universal Serial Bus controllers - depends what drivers you have installed
3. Delete STM32 Vritual COM port driver (or something simillar) or STMicroelectronics Virtual COM Port (COM1-XY), and choose "Delete the driver software for this device" if available
4. Download Zadig from here for the correct OS: http://zadig.akeo.ie/
5. Run Zadig and choose Options - > List All Devices
6. Choose STM32 Virtual Com Port (only one)
7. Under drivers choose WinUSB (v6.1.xxxxxxxx) etc
8. Click Replace Driver or Install Driver (probably the second one will be available after deleting drivers under 3.) and wait a few minutes
9. Download cgminer from here: http://cryptomining-blog.com/wp-content/files/cgminer-3-7-2-gridseed-windows-alt.zip
10. Turn off the HUB or eject all the miners
11. Run the cgminer with LTC_ONLY.bat in the folder with the following flags:
correct the chip number on the G-blade to 80
12. Wait for the main window to popup, then plugin (or turn on) the hub with the miners
13. The cgminer will detect the miners and display the hash rate after it warms up - 10 minutes

I think that the latest versions of cgminer and bfgminer is not appropriate since this one is custom build for LTC mode only. If you have any questions, I do have a lot of work and research about Gridseed miners and you can write me also an PM. Everything what I described was run under Win7 64bit.

Hope you will get what you want!

I'm using the gs cgminer for raspberry it's working like a charm except ... having wrong hashrate .. displayed ...

there have been some forks to adjust that issue ... I haven't tested them ...


haven't tested this ...

https://github.com/siklon/cpuminer-gc3355

Short summary:
* Added hashrate statistics
* Added auto per-chip frequency tuning
* Added JSON API at port 4028 -> send {"get":"stats"} to get stats for each miner/chip
* Input any frequency you want


It should work on Rpi, but I haven't tested it yet.

Sadly pulling and pushing them back in did help once .... on my win 8.1 machine but it never found the second board, no matter what i do it simply did not start the second board
Power it down/up plug usb plugs in/out nothing helps

I had the crazy idea to change the usb cable to a shorter one and since that i can install the stuff as long and often as i want it won't find the boards

When i put the miner onto usb hub for the pi i instant lost them and now unplugging/plugging in any port does not make them work

However that weird 3.8.5 version saw the blades instant as btc miners that was the most odd i ever notices it went up to 10 Gh/s and was building up speed, but i do not want them to mine btc

Does the cpuminer support the g-blades ? how to get it to find all 80 chips

I got it now running with the bfgminer 3.99  at around 3 Mh on the same usb hub and cables connected to a win 7 htpc

Installing zadig end again in cgminer not finding the devices
You guys using zadig 2.1.0

Run cgminer 3.7.2, and when it says no devices found, unplug the usb to the miner, wait a few seconds, then plug it back in.  It's no secret that cgminer has this problem.  cpuminer doesn't seem to suffer from this issue and it doesn't require the stupid zadig process to replace the drivers either.

Hmm i think i never buy usb devices ever besides stupid mouse and keyboard.
Been 4 days busy to get anything working at all

What a freaking pain in the behind again to get anything running as it should
I got a G-Blade 80 chips but this far i only got it running on my win 7 box with the bfg 3.99 GS version
Which btw runs only 3 Mh not anything near 5.2 Mh
And it constant wants to start the not able to mine ati gpu ....... could not find a command to disable the gpu from the command line in the non existing help files

I tried the cgminer but guess what i does not work ... Sigh
Freaking zadig installed (BTW I hate zadig) , with the latest blade compatible cgminer 3.7.2 to get YES you allready know "devices not found"
I remove the crap zadig by reloading the driver for the board
started the cfgminer and its running again at its half speed pace.

I looks like its simply not able to run normal on windows, i got a pi and that is also not working besides the very old GS 3.8.5 version which starts mining yes ..... BTC .... sigh
When i try the new 3.7.2 i get YES no devices found .....

If copper shrims are 1mm thick and cheap then this i think will be better than the pads since they are rated HIghest in w/mk then u add some good thermal paste on the shrim and close up.

Also is anyone aware of the development of cgminer seems some rushed ths gridseed version + oc version as there are soms bugs ...quick example of 2 bugs ...

1. In between the listing my accepted shares I get the repeat lines that show the same bit as the  batch file showing 5 chips and baud115450 etc etc . This doesn't happen everytime i start cgminer.. usually  it only shows the pool information and the      accepted shares.

2. The 2nd one I noticed Crashes when i close the lid of my laptop. Instantly cgminer crashes.

Very annoying

If there's any warranty on it consider returning it.  If no warranty then you could check that the screws aren't too tight.  There have been a few comments recently about over tightened screws potentially causing problems.  It looked to me like the fan wires had been crimped during assembly on the one I returned because of the unrecognized device USB error. I thought maybe that caused a short.  Just a guess on my part though.

Still Unknown Device for me with both of those installed.
Thanks for the effort though!
Maybe a bad device, might have to try doing the reset switch or something.

You can get the drivers from EastShore Trade's site here: http://eastshoretrade.blogspot.ca/2014/03/driver-important-reference-gridseed.html

Right under where it says " IMPORTANT If the driver not works, you can also try the drivers below". The first is CP210x and the second is STM32.  Once Google docs open click one File then click on Download. Do that twice; once for the CP210x drivers and once for the STM32 drivers which happen to be named LIGHTNINGASIC Gold miner USB driver_V1.3.1. I use the second one.  All of my pods are STM32.  I think all newer ones are. Probably from early March is my guess.

Thanks for the reply!
Where do you recommend I get the drivers?
How can I tell which chip I have?
After a while of having it plugged in idle, the red and green lights seem to cycle very slowly between on and off.
Maybe about a minute or so, but not in sync as I powered it on then plugged in the USB

I tried a second USB cable I know works as I use it on my wifi dongle, and got the same unknown device error.
Tried uninstalling and reinstalling the drivers as well, though the install goes so fast I assume it's not fully uninstalling them.
I'm plugging it directly into the computer's USB 2 and 3 ports.
Is a powered USB hub some how required over motherboard USB?
