i got myself a complete Antminer T17+ with 3 dead hasboards for a very good price.... for parts i bought S17PRO boards.... i replaced all missing resistors and changed some asics because they were bad... but wihout a tester... i used the miner instead and changed firmware to awesome miner firmware for better and faster diagnoses via miner log and lower fan speed...
for my understanding and what i read on the internet these asics should be interchangeable in one chain but in my case i´m getting no more communication to none of the asics on all 3 boards. 2 of the boards weren´t in...
HI EVERYONE
is the IT8689E BXA EQUIVALENT OF IT8689E CXA can i replace IT8689E CXA WITH ANY IT8689E ,
someone replaced IT8689E CXA WITH IT8686E CXA he mentioned after replacement don't found in bios cpu temp and fan speed but the motherboard works fine .
I have this board no boardview no schematic :'( , first 5V chip was heating 100°C +.
We found 6 ohms on 5V (5V_SUS i guess)
After injecting on this line we found that a 8pins QFN chip was heating. (Marking " jwfun " " 3a3vy )
After removing this chip 5V chip stop heating.
After some diging i think i found a partial match replacement (JWF6 instead JWFU) from a chinese brand "H&Msemi" >> HM3413D
Pinout match perfectly.
But i can't find this chip...
Any idea? for an equivalent...
