Question about Corsair Vengeance RGB

Yes, at 2000 MHz FCLK with 1.4v (EXPO). It worked at first for 6 months before the BIOSes since 10/2023 which limit Voltages to avoid damage to the CPU.

Since then, with the Gigabyte Aorus Elite AX I can't reboot, only switch off and then separately boot the computer. I think it's the motherboard, because it works fine with Memtest86 and for all games.
