Hello! So I has a PC that ran with a C2D e4500 overclocked by 900Mhz with the memory (Kingston HyperX 1066) at 1110mhz. Since replacing the CPU, the memory will not clock to, or over 950Mhz without failing POST. The CPU was greatly down clocked (and tested stable) for testing the ram. I have tried changing MCH voltage with no luck.. So whats happeneing? D: The motherboard is an ASUS P5B Deluxe. Thanks.
