k heres the deal, my mom has a C2D PC with 1 gig DDR2 667 mhz (2X512) I really want to use her PC for gaming as well so is it possible to mix DDR2 667 with DDR2 675 mhz? I want to make sure B4 i order some more ram

Unless that ram is overclocked then it is 667 mhz, and also if you can stick to the same brand of ram,

If you put in 1 stick of 667mhz and 1 dtick of 533mhz ram, it will underclock the 667 to 533. Thus lowering your memory bandwidth.

If the motherboard has an nForce chipset? Of course that'd be a big mistake.

Now, if the motherboard comes with an Intel chipset? Of course it can take it w/o a glitch.

A board with an Intel chipset can take mixed RAM, just as long as it works. DDR2 667 will work with DDR2 675 just fine and one can mix DDR2 667 with DDR2 800. Though that will never happen with an nForce based motherboard.

I did it with my XMS2 675 and HZ 800.

Now, that will happen and the default RATIO will be a 1:1 and the system will definitely be able to overclock, but maybe a max of 350mhz will be. Depending on how good is the 533mhz kit.
