Hi everyone! May i put two different processors (same family) on a dual socket motherboard? My mainboard is D5400XS and my single CPU is Intel Xeon E5420. I want to do some work with dual processor development by adding another CPU. But i could not find to another E5420 to buy. So can i buy different CPU (same family, ie: E5430, E5440 or E5450) to make them work together?

Thanks.
