Can I mix same brand memory but cas2 with cas3?

[stppetty]

I know you should try to match the same kind of memory you already have in the computer.But Can I mix Cas2 memory with cas3.I have a stick of 128mb PC133 Corsair cas3.I'm going to upgrade to 256mb.I'm going to buy another stick of Corsair 128mb PC133 but can I use cas2?They did not have cas2 available when I bought the memory when I built the system.Thanks for any advice.

Go for it! If your CL3 works, then CL2 also will. Honor the old stick by leaving your settings as they were.

BTW ~ There's no really good reason to get the more expensive CL2 unless you plan to abandon the older stick and explore overclocking above 133 with the new one.
