overclocking ram timing questions

I read in this thread:
Quote:
When 1FSB:1RAM is overclocked above the rated frequency of your RAM use the following values
Timing: 5-5-5-15
vDIMM: 2.2V

e.g. DDR2-667 4-4-4-12 1.9V operating at ~400Mhz will need to be set to 5-5-5-15 2.2V


I ordered the 2 gig kit of Crucial branded "Ballistix" DDR2 with the following specs:
Quote:
# Module Size: 2GB kit (1GBx2)
# Package: Ballistix 240-pin DIMM
# Feature: DDR2 PC2-6400
# Specs: DDR2 PC2-6400 • 4-4-4-12 • UNBUFFERED • NON-ECC • DDR2-800 • 2.2V • SLI-Ready • 128Meg x 64


I'll be running the q6600 on a P5B deluxe and wanted to start out @ 9x333. Since this RAM is DDR2-800 @ 4-4-4-12, I'm assuming I don't need to drop the timing down to 5-5-5-15? Is this merely a starting point for ddr2-667 or what?

Also, what would recommended settings for the other memory parameters in the BIOS be? Here's a screenshot from vr-zone showing more info than I see in my current Athlon machine:

    YES & YES :)

    Set first four parameters, leave the rest as it is, disable Static Read Control. Don't do both OCings simultaneously, CPU & RAM. Start with CPU, as you'll achieve stable & satisfactory OC go to OC RAM.
  2. Cool, I'll probably put the machine together this weekend and just for the hell of it, report back :)
