DGX very stubborn trinity

[faizy]

okay have been at this trinity for 4 days now .... have done 15-20 trinity systems and many coronas with no such issues .... this system is a pain ..... have tried multiple wire lengths for cpu_rst and post_out ...if RST length goes lower than 10cm the fan start clicking after 6-8 pulses ... if i go higher than that ... it glitches forever ... ive left it glitching for 30-45 minutes every attempt .. and ive checked the system on stock nand it still boots fine

tried the original points and alternates top side of the board and bottom ..... soldering is perfect .. have redone a couple of times ... any suggestions ? thanks in advance

Sometimes the veeery short cpu_rst wire can help (solder it to the trace near CPU).

Have you tried bigger gage wire(24 awg) for cpu_rst? 70+cm 30awg kinar wire for post_out?

yep tried the black GND wire for CPU_RST with 70cm kynar post_out .... fans start clicking after 2 mins .... tried unplugging and replugging for 2 hours ..
