please list ALL of your settings.

Multis and voltages.

Here is my hardware config and overclock related BIOS settings:

Gigabyte EX58-Extreme (flashed to F4m)
i7 920 3837B075
2x3GB Corsair Dominator 1600Mhz (white slots)

CPU multi 19x
BCLK 205Mhz
Uncore 17x
QPI multi 36x
Memory 8x  (1640Mhz) 8-8-8-24-1T

Performance enhance: Turbo

vCore 1.35v (1.296v load CPU-Z)

CPU PLL 1.88v
QPI PLL 1.3v

PCI-E Frequency 101Mhz

I've tried 203Mhz and 204Mhz BCLK and both times Vista detects 6GB of RAM and I'm running Prime Blend now without a problem. But once I start getting into the 205Mhz+ I start having issues with stability and Windows only detecting 4GB or less.

I called Gigabyte tech support earlier but the lady I got wasn't really any help. She said it was probably my CPU because of the memory controller and at 205Mhz it's pushing it past it's limit. That's kind of what I was thinking it might be but noone else seems to be mentioning Vista detecting less RAM when you clock too high. And going from 204Mhz stable to 205Mhz isn't exactly a quantum leap lol.
