Maximus Formula X38 w/ Q6600

[vivek_kothari92]

I have a maximus formula x38 board with a q6600 (VID:1.325) on a noctua cooler. My current settings are:

Q6600: 425x8=3.4ghz @ 1.4625V
4gb pc6400: 850mhz (stock voltage and timings:2.0v & 5-5-5-12)
X38 NB: 1.65
CPU PLL: 1.6
VTT: 1.36~1.38 (not sure exactly)
CPU GTLREF: .63x
NB GTL REF: .67x

How much should the voltage on the north bridge be? Is 1.65 to high for a 425mhz fsb? And secondly, what should the voltage be (estimate) for the pc6400 ram to run at 850mhz?

I would keep it under 1.6 for long term operation
