I just ordered an IWILL kk266 and a T'bird 266 for a new system. Here's my question. I plan on ordering a 256m stick of Crucial to go with it. They have CAS2 and CAS3 available. I already have a stick of 64m CAS3 sitting around. Will this MB run OK with the CAS2 stuff? Can I mix CAS2 and CAS3 memory ion the same board? Should I buy one stick of 256m or 2 sticks of 128m. Thanks for your help.
