i have a ram frequency of 166 which it says in cpuz could some1 tell me how the ram frequency works, does it depend on wat cpu u have or is it just the type of ram u buy i was going to buy a stick of ram from the shops but it says its frequency is 333mhz but my current ram is 166 mhz :S Presscot 2.5g @ 533/133 2x256mb Samsung Pny geforce 6 6600 GT 40gb seagate HDD i845GE

Basically speaking, the figure CPUZ gives you in the frequency box under timings is half the effective speed. Thus 333MHz (PC2700) is what you want. That is why DDR is called DDR (double data rate) Hope this helps ps. presumably you have 256MB not 248.

o i c ty for ur help yes i have pc2700 Presscot 2.5g @ 533/133 2x256mb Samsung Pny geforce 6 6600 GT 40gb seagate HDD i845GE

You may have PC2700 (aka DDR333), but your CPU's FSB is running at 533MHz (4 x 133Mhz), correct? Regardless of what speed your RAM is "supposed" to run at, it should be running in dual channel mode at 133MHz (DDR266) to balance the equation. CPU bandwidth @ 533FSB = 4267MB/sec DDR266 (133MHz) @ dual = 4267MB/sec If you run your RAM at 166MHz (DDR333) in dual mode, the RAM's bandwitdh is 5333MB/sec & the system is out of balance.
