My 6 bucks E2160 arrived today (that was really quick!), so i couldn't resist doing some more test annnnd SUCCESS!!!! My CPU was toasted, i think the guy in charge of assembling my pcb was short on thermal paste .... never saw so few and considering those machines are up like 24/7 this was short term suicide. It only took one automated reboot to be greated with CMOS clear screen!
So here is my complete procedure in case some people are in trouble:
1- unplug power from wall
2 - remove battery
3- put jumper on pin 6-8 on FP (do not use the jumper next to the battery, it's a trap
)
4- plug back new battery
5 - plug power
6 - let it cycle : fans should spin for a few seconds then stop , then start to do it again until cmos clear screen appears (see attachment)
7 - unplug power
8 - put the jumper back to its original position
9- plug power
10 - Enjoy
Additional notes:
- I used a single 2GB DDR2 800 stick on slot 1 and it works like a charm
- I did the whole procedure above with geforce plugged in and output on its DVI0 port
- Dipswitches were all off except dip 5.
- No JVS IO was plugged to the mobo during the process
Final note:
Thanks to everybody who helped me during my troubleshooting journey, i really appreciated you kindness
