Spread spectrum

I was wondering if spread spectrum needs to be enabled when there's only one computer in my house, and therefore, no other machine to cause interference to.
The only reason why I'm asking, is that I just want to see 3700MHz reported, rather than ~3696Mhz. :p

Correct me if I'm wrong, but SS slightly affects the base clock, right?

I have never found it to make much difference in overclocking but its impact on emissions seems to have decent industry support. Its your computer, until Apple owns your sorry ass you can do what you like to get that extra 4 Mhz :)

I'm not looking for a performance/e-peen increase. I just have a little OCD, when it comes to seeing a reported frequency of 4MHz short. xD
Would it create noticeable issues with cell phone reception, or other RF equpiment? If so, at what frequencies would I be seeing peak interference?

All it does is vary the clock speed of the buses slightly so that they are not in step with each other thus turning it into a somewhat more random noise rather than all being the same frequency at the same moment. I don't personally hear the computer in speakers/mobile phones at all these days. Its in there presumably because it makes a difference, but not that you will likely ever notice.

Ever since I started tweaking and OC'ing, I've never enabled SS. Don't have problems with other equipment -- anywhere in the house. And I think we're running on average about four machines 24/7 concurrently -- with "spread spectrum" disabled on all of them.
