I´m just foolin´ around with the socket7 stuff, and this mobo shows me a 473MHz of my 4.5x100 setup of K6-2 450 (Chomper eXtended). Just all of a sudden. The only sudden change is a crappy PSU with high pitch noise, so I think its dying, but the mobo runs fine - till now. The previous PSU borrowed from my friend just died 🙁

Just want to ask if there might be some overcurrent or overvoltage phenomenon of something that might cause this effect.
