|U should configure ram settings according to manufacture specs.|
there are settings u need to set before overclocking
-lock pcie @ 100mhz
-lock pci @ 33.33mhz
-disable spread spectrum
-disable EIST aka speed step
-disable cpu enhanced halt CIE
-disable cia 2
*don't use any overclocking profiles*
c2d e4600 2.4ghz 800fsb cpu multi x12 and (1.162-1.312v).
We are going to use ratio 1:2. Set ram to run @ 800ddr aka 400mhz, pumb fsb to 333 (1333 fsb) and reduce cpu multi to 9, now ram should run @ 1333ddr aka 666mhz. Save settings and restart the system. If system unstable try to increase cpu freq slowly. Eg. 200-220, 220-260, if the system unstable to 260 pump cpu voltage (1.162-1.312v) make sure to stay in range, increase 0.1v each time until u reach 333 stable.
Use prime95 to stress cpu.
