Hi guys,
i got 2 sticks Kingston Value Ram 1GB ddr2 Pc-4200, put them in my xps 140, The memory only runs at 266Mhz as opposed to "promised" 533Mhz PC2-4200 - below is what I got from cpuz - The bios does not allow me to reset mem speed. does it mean that only dell memory works at specified speed? is twice as ex*****ve...does that missing 200Mhz really matter?

DDR=Double Data Rate. Multiply 266 x 2.............

BTW: is it just me, or did the post format go really wonky in this thread?

CPUZ only shows the actual frequency at which the memory is running which is nothing but 266 Mhz for you.... But since DDR = Double Data Rate the memory controller actually is able to transfer data twice per clock and hence the effective DRAM clock speed is 533 Mhz
