    I've been looking to get an ASUS P5LD-2 Motherboard that has a lot of nice features. I shopped around for CPU's of the Intel Core 2 Duo type and the best one I found for the price was an Intel Core 2 Duo Conroe E6750 2.66GHz.

    There's one thing though that I want to find out if this will be a problem or not. The motherboard in question has a FSB of 1066/800 mhz, while the CPU is a 1333 mhz FSB

    Will this make the CPU and motherboard incompatible?

    Typically, no. It just means the CPU will only function as fast as the motherboard will let it. This will reduce the processing speed of the processor, but it will still function in the board. Same thing goes with motherboards. You can stick a slower FSB processor in a motherboard, and the board will auto detect the speed, and run at that speed.

    Generally speaking though, you should always try to match the FSB speeds to make sure that you're getting the performance that's been designed by the MFG.

    Yes in this case it will be incompatible. The 6750 has to have a 1333 FSB or it will not run.
