i got an Z690 Formula since 11.11.21 it worked well in the last 2 Years .
i used an 12900k and 13900k Cpu on it . with 64 GB Gkill Trident Z 6400 . Bios 2802
but since almost 2 weeks i ran from one issue into another.
it started with a BSOD , after Restart i got an "unmountable boot device error . in Bios my Primary SSD an 980 Pro m2 , wasnt shown anymore . well i ordered a new ( i thought the 980 was dead) 990 Pro installed a fresh Win11. wich worked for 1 day . then after start next day i got into a booloop ( memory Detect ) i resettet Bios and removed 2 Sticks of Ram Testing one stick by another with memtest86 no errors were found . with 2 Sticks of memory at stock settings (no XMP chosen everthging on AUTO) the system starts and loaded windows.BUT 2 Hours later , maybe less or more , i got the unmountable Bootdevice Error after a BSOD again , that was enuff for me , i mailed the Dealer were i bought the MB , they sended me a Ticket for RMA (gladly 3 years Warranty)
when i removed the MB out of my Tower i noticed Green metallic Particles in my CPU block (whole cooling system is made of EK parts ) and the drained Destilled Water with EK additive . i googled about corrosion with Z690 Formula and found some Threads and Vids .
I also noticed corrosion in the VRM Coolblock trough the g1/4 moountings .
does anyone know how long the RMA wil ltake ?
