    640ht backwards compatible?

    hi, does anyone know if a pentium 640 hyperthreading would still work (without the hyperthreading bit) if I put it on a motherboard that doesn't support hyperthreading? I was gonna replace a pentium 4 2.66 GHZ with the 640 ht and hope that it would just run like a 3.2 GHZ chip, would this work...

    Can I upgrade a p4 640HT to Pentium D950

    Hi, I have a dell dimension 9100 with a pentium 640 hyperthreading, and the 945p chipset. Can I upgrade this to a pentium d950? Is it as easy as just swapping the processors? Thanks for any advice.
