Ok, thank you for the hint. I'll see what I can find.

You're trying to run them without the heatsinks?

 You're lucky the WHOLE BOARD didn't overheat and blow up.


 I agree with the other reply that you likely have a polarity issue - but if you don't get those board reinstalled on the heatsinks and some sort of fan blowing air through the heatsinks you ARE going to have a "all the hash chips overheating and dying FAST" issue.





I've already confirmed that it was a polarity issue.

They didn't come with heatsinks, and I'm only in the middle of building my set up. Heat management is to follow. I simply need to confirm the boards are working and can hash.

At the moment I need now repair the damaged boards by replacing the destroyed components. What components have been damaged? And where would I get replacements from?

Just a quick follow up I've tested the last remaining Gridseed Blade using the recommendation from @PassThePopcorn and no explosions!

Thank you!

Now on to the task of repairing the damaged boards. What components have been damaged and where can I buy replacements from?

The gridseed orbs would pop if you hooked up the power cord improperly, I believe the original power cords that were supplied with the orbs had the wires reversed as in Red = Ground and White = +. This might not be the same issue you were having.

Right, I have one Gridseed Blade left to try. These are the original wires. I will test with the wires reversed.

You mention "The gridseed orbs would pop", am I able to purchase replacement "orbs"? If so where could I get them from?

I'm wanting to get into mining not so much for the mining reward but because I support the idea of decentralised currency and the power of peer to peer transactions.

However I have a problem with getting some Gridseed Blades up and running. Something on them is exploding. Please see the below photos.

This is my power supply unit.

I live in the UK so the voltage is set to 220V mode.

This is the front of the PSU wired up. My multimeter reads 12v coming from the output.

I'm in the middle of building a stack of blades but I need to overcome the problem of something in them exploding.

In this photo you can see there are three components that have exploded. What are these components? What would cause them to explode?

This photo is for comparison, this is a good blade where the components haven't exploded.

I've tried to look for a datasheet or a gridseed blade board schematic but I can't find one.

Every time I connect a blade to my power supply these same components explode. What could be causing this to happen and what could I do to stop this from happening?

Also I would like to repair the Gridseed Blades that have already exploded, is there a schematic for this board, or at least what are the components that have been damaged?
