hi guys,
i recently bought a pair of DDR2 hyperX 800 Kingston brand.

the problem is, im using CPU-Z to check the MHZ of the RAM but the top MHZ i saw were like 444mhz only
is that normal?

and 1 more thing, my CPU got 4 RAM slot and i already got 2 slot of value 1G ram installed on my CPU ( this value ram showed top 333mhz ) and coupled with these new hyperX ram it should be total 4G of RAM.
but the system said it were only got 3.5G of RAM??

please anyone kindly explain this to me since im a super noob on this part >_<
