[GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning

[Andareed]

wtf I can use CGMiner now?!

I am going to donate now kvclivas or whatever it is

not ckolivas, some one forked it for gridseed, as ckolivas said he wont work on any other except sha256 after 3.7.2


I am getting HW errors running 6 gridseed miners in cgminer.
Anyone getting HW errors?

At 800MHz clock I get maybe 2 errors in 24 hours. Higher clock rates produce more errors and although cgminer reports higher hashing speeds the speed seen by the pool goes down. I think 850 might be the optimum but I need more testing.

Both cgminer and cpuminer will report errors if they lose connection to the pool, e.g. if the network cable is unplugged. I noticed that while doing some rewiring around the house. So at least some of the "hardware errors" might not be related to actual hardware.

cgminer, after I twice unplugged the network switch shows two hardware errors for each miner:


cpuminer, after the same, shows a bunch of invalid nonces upon resuming:

If I had to guess, I would say that the miners are returning work for a previous hash.

Has anyone been able to get the cgminer 3.7.2 (for gridseed) to work in linux instead of windows like what is shown here? http://cryptomining-blog.com/1262-download-cgminer-3-7-2-for-windows-scrypt-mining-on-gridseed-5-chip-gc3355-asics/

Yes, even with 10 miners. If there are some interest, I can add the forked cgminer to coinst (https://litecointalk.org/index.php?topic=15312.msg121778#msg121778).

bfgminer 5 chip: https://bitcointalk.org/index.php?topic=168174.msg5600687#msg5600687

Possible to update to this version on minepeon somehow?

I did remove all the fans ..

and so far working well ....

I have the same freezes with cgminer on Raspberry as reported, but I also keep connecting and disconnecting miners and after a while cgminer crashes due to Segmentation Fault. I'm afraid that means I have to format the SD card and reinstall (and make an image of the status at that point.

Due to travels I'll have to let these alone for a while so I'm thinking about buying the cheapest laptop with windows and connecting them to that as there's at least a working version that doesn't crash on windows (and I don't have the 2 levels depth maximum hubwise that the Pi has.
Plus I'll have easier remote access than with a Raspberry and a few controllers from LA.

Step by Step Raspberry SCRIPTA Installation:

• 1 - SD Formatter (link) clean up your SD Card. At least a 4GB SD.
• 2 - Download the SCRIPTA Image (link)
• 3 - Win 32 Disk Imager (link) and write the scripta image on the SD Card.
• 4 - Put the SD Card into your Raspberry.
• 5 - SSH access on port 7722, user: root / psw: scripta
• 6 - Use WinSCP (link) to move over the latest rasp cgminer for gridseed (https://db.tt/UygLkqwd) or Use PuTTY (link)

Code:

wget https://db.tt/UygLkqwd -O cgminer

• 7 - Go to the location where you copied over your cgminer and do "chmod 777 cgminer"
• 8 - Go to the SCRIPTA Web GUI, under Miner hit Miner commands, STOP
• 9 - Go to the location where you copied over your cgminer and run it from there using these commands:

Code:

./cgminer --scrypt -o <miningpooladdress:port> -u <user> -p <pw> --gridseed-options=baud=115200,freq=850

Stability-Fix:

Code:

sudo nano /boot/cmdline.txt

Add the following code at the end of the first line (on the same line as the other text, DO NOT add new line!)

Code:

slub_debug=FP

Thank you darkfriend77! this is a great guide!
We will try to release a new version of scripta where people don't need to do all this... Ideally Scripta should be able to discover different hardware devices (gridseed 5 chips, dualminer and others) and associate each device to a cgminer and a set of parameters, along with the pools the dev should mine on. We have posted a TODO file on github about this and if someone wants to join the team (also for other aspects) please feel free to send me a PM or play with the Git!  https://github.com/scriptamining/scripta/blob/master/TODO
P.S. Apologies if slightly off topic, but I thought it was relevant...

Edit: Some stability issues have been reported and qiqiji on the litecoin forum has suggested to make this small change to the file cmdline.txt

thx, I added the stability fix to the guide.

I did remove all the fans ..

and so far working well ....

Nice layout.
One fan cooling all 10 pods. Nice.
I'm cooling 5 pods with one pod with fan in the center and 4 pods without fan surrounding it.
Running at a decent 80* to 91* F in Scrypt only mode.
The cool air that the center fan throws is enough to circulate some air around the other 4.
They're all within 1* of each other.
I'm testing their temps with an infrared temp sensor gun.
So far, so good.

so u guys run 2x cgminer to once us for scrypt onc for sha or how do u actually us this hardware ?

[deadmilkmen]

Reused a gpu miner frame i was building for a couple 7850 i would going to order.

https://i.imgur.com/5bb5629.jpg

can hold a total of 18. 8+8+2 , 1 psu, and space next to the psu for usb hubs. Was short on material but it will have another rack on the top .
total overkill, but material was cheap.  im sure i could find a way to fit more if i turned them on the side but, 15-18 of them will be just fine for now.



Anyone Come close to 400kh/s yet? Looks like most people are running about 361kh/s .

I just stripped one 5 chip down, removing all fans and heatsinks.  I then proceeded to start mining scrypt with it at 850.  I let it run for about 15 minutes, and using the touch test to see how hot the 5 chips get. 

They don't.  Basically warm to the touch.  I don't think these need cooling for scrypt only.  I'm definitely taking the fans off all of mine, and if it ever gets to the point where they take up too much space I'll take off the giant gold sink and put the little per chip heatsinks meant for asicminers/vram. 

I understand why gridseed has the cooling on them for the SHA side of it, I just wish there was a cheaper option for scrypt only with no fan and small sinks.

Maybe one of the resellers can convince gridseed to just sell the boards, I'd buy some that way.

Anyone have a good source on USB cables that actually fit correctly? I am tired of cutting the ones I'm getting with the miners down to size. I had one from an old HD that actually fit perfect so I know their out there.

This one looks promising but way too expensive:

Do these from monoprice fit?

I bought the monoprice ones with the ferrite core and the connector is just barely too big, very snug fit.  However, you can just bend the fins on the heatsink out of the way, right above the usb port, and then they fit great.  I also have some of the monoprice ones without the ferrite core and they fit fine with no modification.

Why so difficult? My USB cables fitted fine. Just push a little harder, so you bend the fins of the heatsink a little if there is not enough room.

I am getting HW errors running 6 gridseed miners in cgminer.
Anyone getting HW errors?

I have one that has HW errors and the other works fine... Maybe it is a Gridseed thing?

Hi all,

does anyone know if it is possible to have the Gridseed Miners do scrypt-N or scrypt-jane? A new firmware would be needed I suppose.


regards,

P.

Anyone tried to flash the firmware of the miners? I've read the manual from LA but it looks like something I wouldn't want to just "try" for fun

So far I can't find out which firmware is on the gridseeds anyway so can't see if I can upgrade anything.

I'd be willing to give the firmware flash a go. Gota link? I've looked everywhere and have not been able to find any info on a firmware update for these things.
