Will higher speed RAM work in conjunction with lower speed RAM?

[Jamessiviter]

I have a few sticks of RAM here installing in my mothers computer, however, I have 2x4gb sticks of 333MHZ DDR2 ram, and 2x2gb sticks of 667MHZ RAM. If I was to put the 333mhz RAM in, will the 667mhz stuff slow down to work with the other?
Thanks.

Yes.

Yes, you can always mix rams of the same type. The fastest stick will always runs as the slowest stick.

It is called ddr2 for a reason. as the guy said 333 runs at 667 in dual channel mode. that being said mixing ram of different speeds and CAS ratings is not a good idea.

not dual channel, double data rate. DDR.
