Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules. 04-25-07 - tathor - This system can accept either 512Mb or 1Gb based modules, however they can not be mixed. If a customer is reporting a Crucial module
as recognizing half the amount, verify the existing module density (1Gb based 512MB module = 4chip, 1Gb based 1GB module = 8chip) and try to match.
