One Motherboard - Two Processors

[Anttwerrp]

so i wasnt sure if this should go in the motherboard section or the processor section.


So this is the Motherboard that i have. Link

and my questions is... To have 2 processors, do they have to be the same exact processor or could they be two different processors of the same socket? I just cant find it in writing where it says either way. so.. if someone could help point me in the correct direction.
Thanks

I believe they need to be the same S Spec but it's been a while since I've messed with a true SMP system.

They should be the same ... while the separate front side busses would theoretically allow different speeds or even FSB clocks, your operating system will have a real headache trying to balance loads between processors of differing performance. Also, you are well advised to use processors of the same model and stepping.

Overall, even though it's technically possible to mix, there are many good reasons to use exactly identical processors. Go by the S-spec code (for Intel) or product reference code (AMD), for these guarantee that if it has the same number, then it's the exact same thing.

thanks for helping point that out. I will go ahead with two of the same.
