Overclocking problems with p5ql pro

Hi, i had just bought a q9550 and this motherboard. so i tried to overclock.
the problem is that i cant go over 333fsb. whenever i go over , it would says "overclocking fail"

My ram is kingston ddr2 800 2gb X2 . and i tink its my ram that may prevent me from overclocking

Any ideas?really appreciate it xD!

and i set my volts to all auto(dont really know wat to put)
My temps are 40(idle) ~ 50(load) .

q9550 at 2.8 (333x8.5)
asus p5ql pro
2 x 2gb DDR2 800 kingston

thanksss xD

  1. If your basic RAM setting is on AUTO, you may be trying to verclock your RAM and that is limiting your CPU overclock.

    Try changing the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in step with it. If you are at 3.0 GHz (353 MHz X 8.5), your memory clock should be at 706 MHz.

    Download CPU-Z to check your FSB:RAM ratio.

    Warning - confusion factor between what the BIOS calls things and what CPUZ calls things. What the BIOS calls "memory frequency" is actually the memory clock. What CPUZ calls "memory frequency" is half the memory clock - DDR2 RAM, remember? It transfers two chunks of data each bus cycle. What you want in CPUZ is a 1:1 FSB:RAM ratio.
