Overclocking E4400 to 3.0

I have a system on the way and am looking to OC my processor a bit, and I have some questions.

First, it'll be a E4400, and I want to go from 2.0 to 3.0. I'll be using an artic cooler 7. I want to overclock to a safe/conservative # and from reading it sounds like 3 will be fine with that cooler. I also want to do this without increasing voltage. Is this likely? Is this safe?

I also have some 800 corsair ram, 2 x 1 gigs, and want to go from 5-5-5 to 4-4-4. Can I likely do this without a voltage increase? This ram was only slightly more expensive than 667 ram, but as an afterthought.. will I see any benefit from this system with the 800?

The guides out there or mostly for the 6xxx series, so I wasn't able to get a whole lot of info on the 4400, since this is just coming out.

Oh, and I'll be using a Gigabyte 965P-S3. Thank you!

Well, it does do 1066 fsb, that won't cut it?

Should I get a different board then?

Those other boards aren't much more expensive.

The reviews on newegg for this board say they can get to 400, why would going to 300 be a problem? Is there something about the 4400 that I'm missing that makes this a bad motherboard for it?

im interested in your setup. I have an e4400 @ 3.0ghz with a DS3, but it's auto vcore bumps it up to 1.4 volts. i was able to get it down to 1.2 volts, but it was unstable (stock 1.325 volts). I really want it to stay at stock volts.

What mobo did you end up using, and was your stock voltage 1.325 volts?

Also, do you mean 59C under full load?
