Install Sisoft Sandra and look what it says under motherboard info when you have that memory stick in there. It is usually able to read the memory timings off of the DIMM.
Personally I think its CL3. Usually 7.5ns PC133 memory is CL3, while CL2 usually has 7ns memory.
Husband:Hmm, aparently when you die you can come back as something else
Wife:Really! I'd like to come back as a cow if I die
Husband:No, you're not listening to me...
