Performance rating is whacked which tells me sandra or that version of sandra does not support i865 or i875 / p4c platforms....
PR6500's!!! I don't think so....I run faster speed and get same cpu marks (minus the mflops which is being helped by hyperthreading) and I get like 3400-3500 pr rating...DCDDR mobo and memory bandwidth like yours doe not make that big of a difference over my SCDDR chip running 450mhz ddr (3300's sandra)....
