My problem seems to be going any higher is going to require more customized voltages on things I currently have set to "auto".

If you could suggest voltages that I currently have set to auto, to their "mid-range" manual setting that would be great. I can easily bump it up/down from there.

Thanks so much for your help it is GREATLY appreciated and I enjoy learning from you.



I will openly admit that I have not tried "bumping down" my CPU vcore as of yet. I was hoping to leave it at the current setting, or raise it if need be when trying higher clocks. My temps are "decent" for now so it wasn't a priority. I wont know for sure until I get some good settings/advice from someone on what voltages to "try" for a 4.4-4.6 O/C.

The other thing worth mentioning is my RAM is only spec'd to 1600mhz, so I may have to set it to 13xx while running higher O/C tests and upgrade to a higher spec if I can't get these sticks to go higher.
My starting specs for overclocking are as follows...

BCLK 200MHz
Multiplier 21x
DRAM 8-8-8-24-2T (starting with this always, I tweak after; your DRAM will vary based on specs)
LLC Enabled
Vcore 1.35V (starting value, generally lowered at least 0.05V for 4.2GHz OC)
QPI/DRAM 1.35V
DRAM 1.65V
IOH/ICH 1.11V

Using "auto" voltages is not a good idea. Also, from my experience you will need roughly 0.06V per 100MHz extra past 4.2GHz. Achieving 4.4GHz with decent cooling is perfectly possible. Achieving 4.4GHz+ is much harder. 4.5GHz+ or even 4.6GHz will be very tough for 24/7 use completely stable on an i7 920 because the BCLK is getting up there (by stable I mean LinX stable, Prime95 stable, and able to use S3).
