Want to ask, is it safe to run my Q9550 at 3ghz with FSB 353mhz and ram memory at 847mhz while maintain PCIE at 100mhz

or should i detune my ram frequency to 706mhz at 2.00 multiplex?

i think no problem.. if u using ddr2 800..

im still running 3325Mhz @1.25v and my ram at 802Mhz..
( still funding for CCF or RS)

how do i tune in BIOS to maintain ram speed of roughly 800mhz?

Cause if i follow one of the forum thread form lowyat.net, guide me to detune the multiplier for ram to 2.00 which i only achieve 706mhz. If i set auto, it will bump to 847mhz. That worries me if i screw up my ram.

Erm, unless you're using Nvidia chipset, else I think is not possible to unlink your RAM with FSB. In short, your RAM Clock is strapped to the FSB. You raised your FSB to overclock your CPU, hence RAM clock will be go either higher or lower depends on how you set your multiplier.

Your RAM probably won't screwed at 847Mhz, instead if your RAM can't tolerate the additional 47Mhz, it'll cause your system become unstable. For a simple and effective test, run memtest86 for at least two passes, and see if any errors, else it's good to go smile.gif

If errors detected, you can either put more juice to your RAM (of course you should know where the safe limit is), or lower the clock to 706Mhz and tighten your timings. Which to do is up to you.

What RAMs you got btw ?

Is it a wise choice to downgrade motherboard from P45 to P43 just to run cheaper rams which is DDR3.
