on cpu-z it says my ram is running at 200mhz freq it should be running at 400mhz, both of them and my bus speed is running at 255mhz should be 266mhz :P not much but yh and i want my ram to run at 400mhz but i cant overclock my bus over 280mhz because my mobo is poo so is there anything i can do other then get a new pc to get my ram to run at its max. if anyone can help would be great i have been looking around google etc i probz didnt look hard but had a little look tom get help couldnt really so i came to this website. also im new to overclocking :P so i dont know much.
oh and this is my cpuz info.
asrock 4coredual-VSTA
intel core 2 duo e6320 1.86ghz
geil ram 1gb ddr2 PC2-6400(400mhz)

Your ram is running at 400mhz(200 x 2)but you should be running your ram at the same bus speed as your cpu and it is not.

o ok ill change it but im sure my ram should be running at 400mhz per gig not 200mhz per gig which it is at the moment

With a Core 2 system, you should keep the RAM frequency in sync with the CPU frequency. So even though your DDR2-800 RAM is rated to run at 400MHz, it should be run at 266MHz to match your CPU. Try manually configuring your BIOS settings.

Your ram is ddr so 200 is 400mhz effective, follow Jams advice and set it to 266 which would be 533 effective.Your ram is not running 1:1...this equals a performance penalty

The difference is that normal ddr ram goes as fast as 400MHz (real 200MHz) and your ddr2 ram is build for up to 800MHz (real 400MHz).
The others are right that you should run your ram in sync with the cpu. The problem is to know the right frequency.
For example, if your intel core 2 duo or quad cpu has a fsb of 1066MHz then the ram should run with 533MHz (real 266MHz). Two ram sticks together in a dual channel ram setting give you the 1066MHz to run in sync with the cpu.Yes, I know it's not totally exact to add those ram frequencies but that's one of the ways to figure it out! ;)
