whats the highest ram rate for my mobo?

[chipbgt]

I have the asus p3b-f mobo from about 3 months ago, and I currently have 224 megs of pc100 ram....now, while at the moment I certainly dont need any more ram /forum/smile.gif, can this motherboard support the new pc-133 ram? and is it compatible with my old pc-100 at the same time? Thanks in advance

It acctually depends on the memory. Most memory can be used on slower machines but not all. You also have to be aware that you cannot use PC66 mem. while running a 100mhz bus but you MAY be able to use PC100 on a 66mhz bus or PC133 on a 100 mhz bus.
