Processor with higher FSB then motherboard

Hi, my main computer broke so I was trying to figure out what was causing it problems. I tested the RAM and it wasn't that, the PSU was good, the hard drive was fine, etc. So I wanted to move onto testing the processor: I have a q6600 processor, and my secondary computer has a socket 775 motherboard as well. However, the motherboards FSB is 800mhz, and the q6600 has a FSB of 1066. Is it alright to test the CPU in the motherboard?

(The motherboard is from a Dell 4700, it's a OM3918 motherboard made by Dell. The chipset (I dunno if this is important to the question) is Intel i915P/i915G.

Sorry for confusion, I was just looking at CPUZ, I think it's an 800mhz board because the CPU in it right now has a FSB of 800mhz, but I can't see where it explicetly says the motherboard has a FSB of 800mhz.

I hope this is enough information for people to help,

Thanks ahead of time,

I doubt the CPU will work in that Mobo.
And it's more likely that the fact it is a quad than the FSB.

Often the CPU will downclock with the FSB.
However, since those boards know nothing about 4 cores, they will be confused as all get out.

So sounds like no.
Other then finding someone with a motherboard that supports my CPU, is there any way to test it? Also, could using a bad processor on another computer possibly damage it in any way? My dad has a work computer with a motherboard that supports it, but he's afraid using a faulty processor could break it or some other component on his computer. Is there any danger in that?

Thanks again,

Yeah I'm pretty sure it's the mobo because my last on broke (it's a 780i...) and I got a refurb RMA one which booted and then crashed and then never worked again. The tech guy wanted me to try testing everything else before I applied for another RMA.

thanks
