Short question about OC q9300

Sorry if my question wasn't cleared/sounded stupid but like I said I'm really new to all of this.
My CPU-Z is showing a RAM frequency of 333 MHz (eventhough my pc2-5300 are supposed to be 667 MHz?).

In the BIOS my current CPU settings are 7.5 x 333 MHz = 2,5 GHz. Now is there a way to increase the CPU fsb with my current RAM?

First, if CPU-Z is displaying an FSB:RAM ratio of 1:1, your RAM settings are all right. CPU-Z makes a distinction between RAM frequency, which in a Core2 system matches the FSB freq, and RAM clock, which is twice the FSB freq (DDR2 transfers two chunks of data during each bus cycle.

You should be able to push the RAM a little higher. Take your RAM settings off Auto and at stock FSB freq, set the memory clock to 667 MHz. Increase the RAM voltage to 2.2 volts if it already isn't. Then relax the timings to 6-6-6-18.

Now you can do the usual overclock stuff - increase bus speed, test, increase CPU voltage, repeat.

While you are at it, take a look at our generic C2 OC Guide:
