Gridseed Troubleshooting

[ck]

Hey everybody,

Quick qn!

I've got 20 grid seeds connected to the raspi via a powered USB hub and its been hashing well for a couple of days. Just yesterday, the hash rate dropped significantly to around 2/3 of what it used to do.

Upon inspecting all the Gridseeds, I noticed that the lights were all flashing but when I did a screen into each individual miner, some were not able to find any blocks.

Any idea why this may be happening? Could the Gridseeds be faulty or is this caused by something else?

Very strange indeed...

Cheers

Here's a screenshot of what I am seeing in cgminer. The strange thing is that all Gridseeds are powered and chumming along, as per cgminer results. They're just not getting any shares accepted.... weird stuff...

Could be a power issue perhaps? Do you have 1 standard PSU?

Try changing the PSU, if you have a spare one.

WOW both of you were right, it was the PSU! I just swapped out the power brick for a new one and so far its been chumming along nicely.

Thank you so much!
