Good work MusicIsMyLife.

A quick few things:

Your motherboard options and even some BIOS mapping values are going to vary from one board to another so be careful in what you name the guide (make sure you name the BIOS version you used as well as the boards early on because there are differences). For instance, MSI K9A2 Platinum doesn't have 0/1 for CPU/NB DID but divisor 1, 2, 4, 8, 16. 1 corresponds to 0 and 2 to 1 and so on.

The BIOS values for DRAM on MSI 790FX are:
1:1
1:1.33
1.1.66
1:2
1.2.66

Although in windows they will show up as 1:1, 3:4, 3:5, 1:2 and 3:8 as you stated.

Some boards (ASUS 790FX) have the CPU-NB voltage manipulation in the BIOS so they can OC the NB clock speeds too with better stability.

Yes, so far many users run 2.2V/2.3V daily on memory. I run this too without any problem. I did do on one 9500 for 2 months (upto 2.9V) and two 9600 too (upto 2.4V) as well as this 9600 BE for 2 days at 2.2/2.3V. You might have seen Sami of AMD running OCZ 1066 kit rated for 2.3V with retail Phenom 9600 BE on the MSI 790FX board as well, pretty regular.

And yep, 9500/9600 start to get unstable with higher than stock IMC speed (NB CPU) and thus require an increase in CPU NB VID/voltage. If you can't do this, you can't achieve much stability. Best overclocking is done with NB/HT at 5x/6x multiplier.

9600BE is a different thing altogether since it has unlocked NB VID/CPU VID control, you can run a 12x multi on the NB for sure. Higher hasn't worked for me yet (not a stability issue but looks to be a BIOS issue).

Higher NB DID than 0 has also not worked for me yet.

Disable Spread Spectrum Control and extra hardware/ports on your board before OC.

Keep MaxAsyncLatency (MaxReadLatency) and tRFC high when trying for high HT ref. OC.

Test the HT ref. limit of your board first, then your Phenom HT ref. limit at a low multiplier. It's best to proceed after this.

1. Manufacturing/core design issues.
2. Yes B2 revision of the CPUs have a TLB errata. Though no ones experienced it yet on the desktop level to our knowledge.
