@ Chef - don't worry about the RAM. If you'll notice, a lot of us guys run the ram at lower speeds, but with tighter timings (lower # the better). The RAM can always be manipulated to run at or around the stock speed (just under stock speed is always more stable than just above stock speed, I think).
In terms of your goal of 3.8Ghz, here's what I'd do.
1 ) Download and install CPU-Z (please double-check the version you're getting so it reads i-series architecture accurately). This will get your stock voltage for your chip running at stock speed (otherwise known as your VID - the minimum amount of voltage your specific chip requires to run @ stock).
2 ) Write that voltage down. Now, boot into your BIOS and set the vcore (or cpu voltage, some BIOS' phrase it differently) to that number. You might not be able to get it exact, but get it as close as you can.
3 ) Now, start messing with your speed - with your i-series chip, the only way is increasing the bclck (base clock). I would turn it up by small increments to start. Save your settings, reboot. If all is well, repeat this process - WITHOUT changing your VCore. The goal here is to see how fast your chip can go without manipulating it's voltage.
4 ) Once you finally blue screen: this is the sign that the chip can go no further without increasing the vcore. Now you can increase that vcore 2 wee notches, and hit more speed (same wee notches you've been taking in step 3).
5 ) Incrementally repeat 3-4 and you'll be on your way to overclocking your chip. Sure, there's a fuck-ton of other settings you can mess with, but that's more so the fine-tuning of hitting a hard number to hit for a given chip. Take the basics first, I'd recommend.
6 ) During this entire process I would monitor temperatures fairly closely, at least once you start raising the vcore. I always use (and tend to recommend) CoreTemp, as I've noticed it's fairly accurate. Free download via Google.
Post any questions along the way, I'll try to check often and reply back
