Yeah, I replace the chips but the problem always there. I change basicaly everything around the chip and nothing happened. Same error 24.
That's a deep dive, how can you sure that the chips you replace are defective/damaged chips? Where did you get the chips that you replace on hashboard chips? You might get the chips from another scrap hashboard or maybe you bought them online?
Replacing all chips is a deep dive unless if you are an expert on hardware issues. What I can suggest is better replace the hashboard or if you want to go in deep hardware solution you will need to get a hashboard that you know working and use multitester to check every line from the chips and use the working hashboard as your reference. This will be a good start to find the difference between damaged hashboard and working hashboard.
In case you can't find the damaged chip better to replace it with a working hashboard because replacing all chips will give you a headache.
I change the chip from the hash-board and yes they are replaceable. They're 114 chips.. so I run a diag to see where the problem is.
And with this one in particular, it say the the SPI is failing somewhere between those chips.
I tough it was the UT3 but it isn't.
The software won't tell you which one is damaged since your problem is related to hardware as I said above you will need a multitester to find those damaged parts.
