Topic: [GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning - page 55. (Read 308847 times)

I am using win 7 64bit with the cpuminer fixed power usage (running through a 49 port BE hub), I am running core at 800MHz (some are wobbly on 850)

My question is I can only get between 275-305KHs with each unit? I thought stock was this speed and clocking to 800 should yeald 380+

Is there something I can change? Is this right? I just want to get the most out of a stable unit.

i think its better period. i have much better results

hey guys just want to update i switched to bfgminer and now im running sweet! just have one thats spewing out hw errors.
im over 6MH/s actual nonce (3rd hashrate) in bfgminer. thats with 18 running at 850mhz.

if anyone is having trouble with cgminer i suggest installing these st virtualcomport drivers windows 8 64bit (im using them on windows 7). they seem to work nicely.

Im not having much luck finding the pcie mail sockets with crimp pins...
The molex sockets are easier to find, but still looking for the crimp pins.
I didn't really want to hack an existing cable and have a bunch of electrical tape, looks kinda crappy.

Anyone know of a source for the ATX PCIe (and molex) to barrel plug adapters?
Seems CabelZ is no longer making them...

i saw some guy posted a script to monitor usb ports on windows+cgminer and reset them if one of miner dropped. but i cant find the post now, someone please help me to find the post.
thanks.

For those of you running Windows and CGminer for Gridseed ASICs:

Long time lurker, but new member here.  I usually just sit back and read to solve my problems. I registered here today just to make this post.

I noticed when using Gridseed 5 chip miners with Windows/CGminer that miners would randomly drop off. When you close CGminer or reboot, this was especially true. The fix? Unplug the USB cable to your miner or hub and set hotplug to a higher number than 0 (most seem to like 5).

Great, but I have a job/life/kids/wife/car/hobbies/etc and can't always be next to the computer waiting to unplug/plug a USB connector.

I did a little experimenting and found out that disabling/enabling them in device manager brought them back without having to physically unplug them. This got me thinking...

I was able to use devcon.exe (from Microsoft) and write a quick batch file that enables/disables the miners. Then I scheduled the batch file to run ever 60 seconds (maybe overkill). The good part is that devcon.exe does not disable devices if they are in use, it waits for a reboot. So, your active miners never go down they just get "flagged" to be disabled on next boot and your inactive miners get disabled/enabled and start working again. This also requires hotplug to be greater than 0 (I used --hotplug=10)

It's quick and dirty and by no means a great solution. But it works. If someone wants to take this and expand on it, be my guest.

To make sure its working:
Run CGMiner, make sure it works and miners start.
Close CGMiner.
Run CGMiner, no miners (or less miners) are found.
Close CGMiner.
Run batch found below.
Run CGMiner, all miners working again.

You may need to edit the batch file to include match your miners hardware ID (*5740* is wildcard-part_of_hardware_ID-wildcard). I'm not sure if all hardware IDs are all the same, but all mine are. I just shoved it in the root of my C:\ drive. It's very basic and self explanatory.

I hope this helps some usb plugging, nail-biting, BCTer get out and grab a little sunlight instead of hiding in the basement waiting for that inevitable USB failure.

It is not difficult to make one yourself. Just need to find a molex cable that splits input to 2 output, then cut it and attached to the barrel plug..

Ive been running 20 gridseeds on a single Pi running Hashra Control set to 850mhz hashing at 352kh/s for the last week and only 2 hardware errors so far.

I was one of the earlier Hashra customers (20 pack with accessories) - review --> https://bitcointalksearch.org/topic/hashra-overall-experience-and-some-thoughts-524363

Tonight I was able to try the Hashra Controla flavor RasPI image.. very nice and easy to use.. (I also updated the firmware with ease just two clicks).  I think the only thing missing is some fail over pool options..

I also have been testing out the Zoomhash image on a couple test miners.. not really impressed, but it works. got to utilize heavy putty action tho -   I heart me some Web/GUI interface (Controla/Scripta types)..

My original 20 are running on two RasPIs with a scripta version from last week (10 each).. no issues... I tried to run all 20 (10 per hub both plugged into the pi) no joy.. about 4-6 miners would stop a random times and then the whole thing would freeze up.

I will be attempting the 20 count on the Hashra Controla when I have some more time.

Anyone try it yet?

(if Hashra would have given me the heads up I would have ordered their new 20 pack, but spent the extra 20 bucks and did it through ZH last night (w/coupon code).  I really want to test out the new Hashra shipping speeds...  (edit: looks like a $150 shipping charge is added... that doesn't beat my ZH deal after all)

Why are they pulsing? Are they some sort of cyborg gridseeds?

Never use psu (adapter) from China .. blown a few already.. use PC's psu.

Not sure what's the startup amp .. but your psu is 12v 10a? it can only support max 2 GS in dual mine mode.

Are GridSeeds really this fragile, I purchase 10 and 6 are defective do to a PSU short ? ( is this possible)

Hello Gridseed users.

I purchase a 10 unit GridSeed package that came with a Raspberry PI and 10 port USB hub and two 10A 120 to 12 VDC PSU'.

I connected all the 10 GridSeeds to a the USB hub and powered it up,  then I connected a 1 group of 5 gridseed to a 10A 12 PSU (XHY PV-12012000) using a fan out 1 to 5 power cable supplied with the kit. The other 5 GridSeeds were connected in the same way.  I powered up one group of 5, and when I plugged the second PSU I huge spark was seen on the 12 VD DC line of the 1 to 5 fanout cable all the fans started and then stopped.

I unpluged the PSU and tried it on only one GridSeed and the PSU was dead. It's green LED was no logner on and my voltmeter showed no 12 volt reading.  I then tested each of the 5 Gridseeds and not one would power on, Could they all have died, I though impossible but I got out a better quality 120 to 12V transformer made for CB radio and the 5 devices no longer powered on, and when directly conntected to a USB port no led.  The continuity tester on my volt meter shows a short on all of them !.   

So I powered-up the other 5 Gridseeds left the room for a few minitues, when I returned all of the units has stopped and the fans where vibrating a making a whining noise.  I noticed that the PSU's green LED was flickering.  So the second PSU was no longer able to power the load of 5 Gridseeds not even mining.  I later discovered that the second PSU was only have to operate a Gridseed for a few minutes before apparently dieing out. 

I purchase this kit from Zoomhash.com, and I opened a support ticket.  I've played with electrical gadgets for a while and have seen my fare share of cheap made in china power supplies die. But never have I seen damage on this scale occur so fast; Out of my 10 GridSeeds only 4 work after this "incident", 5 don't even power-on and the 6th powers on but the USB circuit appears dead and the internal LED never come on.

I am really regretting that I did not take the time to test each unit one at a time on my PC to determine that each was working properly as I was so excited to and wanted to get the devices working fast.

I'm still at a lose as to what might have cause this chain of events ?  Could a short in one of Gridseed has caused a leak of the 12V dc in the USB circuit and back in the USB Hub and back in the other GridSeed's ? The USB hub also is dead.
 

Picture of PSU that I suspect was the cause of all this destruction.
