configuring 2 RAMs of different frequencies

hi
i have a 128mb 266MHz ram & i just now upgraded it to 512MB 400 MHZ .. now i want to add these RAMs to my Mobo.. so tht i can get 640MB .. but what do i need to do to match the frequency of both these RAM Sticks??

yes..@sam9s is ight.You cant modify the RAM frquency.Infact you cant change feature of any hardware.

so u mean it will work @ 640 MB but both of them will work @ 266 MHZ..if yes then will it hamper the speed of my comp in anyways, or spoil my 512 MB ram ??
i just want to add this 128 mb ram as i can use it for the shared memory of the onboard grafix..

It won't spoil your RAM. You will get more space w.r.t to RAM, but your frequency of both the RAM will be same, i.e., 266Mhz like the others have mentioned here.

*technically* you can adjust the ram speed through BIOS, but like everyone else has said the max speed you can go is as fast as the slowest, which looks like 266. if you want you could change it to runn at 133, but why bother? plus I wouldn't recommend it, cuz the computer may not boot, and if it does would take longer.

but my 400Mhz ram working at 266 with the other ram gonna be slow?? or the frequency doesnt matter mutch ??
