I very rarely visit this subforum, but I decided it was time to ask you guys for some help.
I've been running my sig rig for well over a year now, and at one point I decided to try my hand at overclocking. Overclocking on the X58 chipset seemed a lot more complex than on my previous Socket 775 setup, but I know most of those new settings have been figured out by now. At the time, I just searched for P6T overclocking guides to see what those guys were doing, but there were a ton of settings that were never really explained and while I eventually reached an overclock of ~3.7 GHz, I never really felt like I understood everything.
I updated to a newer BIOS a few months back and have been running stock clocks ever since, because I wanted to try to beat my previous overclock and do it right. I would like to ask for some assistance this time because I know there is a lot of experience in this forum and I'm fairly new to overclocking (my first experience with it was when I got my C2D E6600 and P5B Deluxe, and my first computer was a 486 DX2 66 MHz back in 1996 or so).
Before I reset my mobo back to the default values, I wrote down the values that I had been using. I'd like you guys to take a look at those and see what I could have/should have done differently, and I'd like to start at step 1 and get this baby as close to 4 GHz as we can. It's the earlier i7 chip (C0? The newer ones are D0, right?) and as much as I'd love to get to 4 GHz, if we can't safely do so then I'll be happy with the overclock that I had previously. The system was very stable with the settings I'm about to list. Stability and a safe overclock are priority #1; I'm not interested in a bleeding-edge overclock.

If there are any more settings that are relevant that I need to post, please list them and I'll include them.
I do have a few initial questions, and might have a few more during the course of this thread (if it gets any replies, lol). Should I be using memory profiles, or is manual the way to go? What's the maximum safe voltage for a long term overclock? I was never able to achieve much more than a BCLK of 175 with the above setup, but I wanted to keep CPU voltage as close to stock as I could to minimize heat and CPU degradation.
So - where to start?
