I have wierd anomaly with one gridseed 5chipper. It seems that only one out of 5chips is working. It hashes 80khs, but gives no HW errors.
I checked its PCB and saw no problems.
Any ideas?

Did you do a volt mod ...and which one...?

yeah, basic 2+2 dots solder together voltmod. Only one miner out of 72 is having this problem.

Sounds like a RMA...back to GAW...72 Gridseeds kit...right...?

I got the same kit delivered yesterday...best bang for the money... Wink

modding voids warranty!

Ofc. Im not going to bother with attempting to RMA it.
Anyway. I undid the voltmod and still no improvement. Double checked all PCB components and found nothing wrong again. Going to wash it with toothbrush and cleaner. If theres some physical disruption then washing cleans it up. If theres faulty component, then i will probably never find it. So washing is my last hope. Cheesy
