Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Is it just random application/game crashes or does it not boot/shut down properly? To help you better, we need to know what your vcore/vmem is, and we need more specific info than just Windows "crashing." Not trying to be a dick but if you want help, you need to provide as much information as possible.
Dont take this the wrong way, but if you cant find the memory timings i think you still have some more thigns to learn before your overclock. They are in the bios, usually in the same place you would find your cpu timings and stuff, they should be somthign like 5 - 2 - 2 -2 or whatever.
