  1. It's for my motherboards sake!
    Okay, what if i put a 1333 fsb CPU onto a 1066 fsb motherboard (P5VD2 VM-SE).
    Are there any consequences? :confused:

    It will work fine as long as the CPU is compatible with the motherboard. The motherboard will adjust the FSB automatically

    But is there a decrease in performance of the cpu?

    OK ruuga, this is obviously an extension of your other thread here; https://www.techspot.com/vb/topic126107.html

    You should probably have asked this question in the original thread. But since you asked here I'll answer it here.

    Generally it's better to install a CPU in a motherboard that won't require a BIOS update. Given the choice I'll always take a plug and play install.

    I suggested the E8400. That really would be the best choice of those 3, if it were going into a 1333Mhz FSB board. Into a 1066FSB board, meh, not so much.

    This is the latest BIOS update available for your board that mentions new CPU compatibilities added;

    P5VD2-VM SE Release BIOS 0506
    1. Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx

    Note that it's dated Jan 28, 2008 The E7400 would NOT be PnP for you, if it worked at all.

    In researching your board, I ran into the situation where they asked me for which OS I had. I didn't had none, so I told them 32bit XP.

    It's actually time for another motherboard, if you want to run the latest CPUs. Here's a new MATX Gigabyte P31 for 63 bucks; http://www.newegg.com/Product/Product.aspx?Item=N82E16813128356 Runs memory @1066 runs FSB @1333Mhz

    Dude, that BIOS update is months before the E7400 was ever released.
