Just got my new P5W-DH with 6600 and 2 X 1G or Crucial DDR2 PC8000. I'm trying to figure out the best DRAM settings for a 3.2 to 3.4 overclock. I'm somewhat confused as to what DRAM Frequency I need as I increase the FSB. Should you target 1:1? if so, how would I get there with the PC8000? What FSB would you recommend, and what DRAM Frequency? More questions to follow and thanks for your input.

your not gonna get much over 425 1:1 with that mobo
try 400X8 set dram to ddr2 800 (1:1)
3200 mhz
see if its stable
run orthos 8 hours
come back
that board doesnt work well with 4:5 divider either so dont get your hopes up for 400x8 with 4:5 (ddr2 1000) cuz it probly wont happen.
you got the wrong mobo for over 800 unfortunately

you dont have to but if you wanna OC the memn as much as possible you might even try 7
but i just 9 on this mobo since my chip does 3.6 with ease
its in the cpu setup section
first setting, enable it

I tried lowering the multiplier to 8 and bumping fsb to 400, but never succeeded. Any suggestions on what type of CPU/Memory voltage that would take. My Crucial PC8000 is rated for 2.2v.
I'm currently running the fsb at 350 with the DRAM Frequency at DDR2-875. Is this good, bad or ugly. Any help is greatly appreciated. I'm just trying to maximize this machine. Thanks.

i would top out the cpu 1:1 first
you may need more volts dude
kill hyperpath
and the 2 settings underneath it
leave cpu at stock volts but try these
fsb term 1.3
MCH 1.55
ICH 1.05
try 400x8 ddr2 800 on the dram set timings to 4-4-4-12
if that dont booot
set cpu volts
to 1.35, if that dont work try 1.4

The vcore is actually reading 1.40v from the bios monitor.
Anything less and it will not boot. PERIOD.
Would I be better off running at 350 FSB with a 9x multiple and lowering the vcore to 1.325? DDR 875 is showing PC2 - 6400 when it boots with these settings.

yessir
everything that works in xp works in 32 bit vista except for riva.

Well it seems like the 400 fsb with 8X multiplier is the sweet spot so far. I'm forced to bump the vcore to 1.415 to achieve stability with this. I'm still trying to understand 1:1 versus 4:5 on the timings. My DDR2 is rated as PC 8000. It's crucial Ballistic so I'm not sure how to get the most out of it.
With the FSB set at 400 I achieve 1:1. So is it safe to say that moving the fsb to 415 I negate this and lose performance? Thanks again.

on another mobo you could go 400x8 with ddr2 1000 (4:5) with 5 cas. this mobo hates it though, I never had success sticking it orthos stable.
