The answer is yes. In fact, if you want to put in a 256MB stick, your only option is a low-density PC100 module because PC66 tops out at 128MB. These low-density modules have 16 chips, with 8 chips on each side. To ensure compatibility, look for part numbers 33L3069 or 33L3070.

BTW, there is no need to ask the same question so many times. See this thread and this thread that you posted about half a year ago. The answer won't change.
