2nd Ryzen 7 1700X killed by my Crosshair VI Hero - Unfounded

[Fottemberg]

Hi All!

I'm here to inform you that my Asus Crosshair VI Hero has killed the 2nd 1700X in 3 months (The CPUs were @ default).

First time, 3 months ago (After 3 months of service).
My rig was:
Ryzen 7 1700X
BIOS 1701
2x4GB Patriot Viper 4 3000 MHz
SSD OCZ Trion 100
Chieftec ECO 600 Watt
Powercolor RedDevil RX480

Second time, one week ago.
My rig is:
Ryzen 7 1700X
BIOS 3008
2x8GB Patriot 4 3400 MHz
SSD M.2 Intel 600P
CoolerMaster V650 650W
XFX Fury X

First time, error 08. Second time, error 02. I have a Ryzen 1500X as backup, and it works (Also, I have 2 other Ryzen on Gigabyte boards and these CPUs work perfectly 24/7)
After first 1700X dead, I noticed it to AMD Italia, and they replaced my CPU with a new one. I thought was a defective sample. But even the new one died after 3 months of service. So, the problem is 99.9% the mainboard: there are huge vCore peaks, even in idling. :\

I think I'll sold my CH6H. I can't change the CPU every 3 months.
