Can't... get.. any.. higher.argh!

[xyberfighter]

Okay so I can't my Q6600 G0 to O/C any higher on my DS3R at 8x400 (3.2ghz). I've read the how to overclock gigabyte xxx thread and the how to overclock C2D/quadcore thread.
A funny thing is that I can get to 3.2 ghz at a 1.35 vcore but I can't get it to 3.3ghz at like 1.375 or higher.


Here's what I've tried:

All power saving options off.
2.00 memory multiplier.
Used a 9x356+ (3.2ghz+)
Ram timings at 5-5-5-15
Overvolted everything by +0.1V and tried a +0.2V on the memory
Used 1.375 vcore and higher vcore.

Temps:
Idle at 1.3500 vcore = 34 C on all cores
Load at " " = 54 on all cores

Specs:

Q6600 g0 with tuniq tower
P35-DS3R rev. 1
4x1gb of G.Skill DDR2 PC6400 5-5-5-15
8800 GTS 640mb
Corsair 520HX
HD raptor

Use 1:1 memory divider.

that's what a 2x mem multiplier means... DDR2 at 800 FSB... a 2x mem multi brings it down to 400... which is 1:1 with my 8x400

up vcore some more.

Just to make sure terms aren't being confused here:

1:1 memory ratio means your memory is running at the exact same speed as your FSB, so in your case your RAM is running at 400, which when doubled for DDR = 800MHz.

If you're running a 1:2 memory ratio, your RAM is presently running at 400x2 = 800, x2 again for DDR = 1600MHz

Just wanted make sure we're all on the same page. Memory usually doesn't have a "multiplier" per se, but a ratio. There are steps in between as well (i.e. 1:1.5 ratio means @ 400FSB, it's 600MHz to your RAM x2 for DDR = 1200MHz).

Note that you may need to bump NB voltage to 1.35-1.45 if you have so so RAMs.
