This system needs BIOS 1.1.11 or higher before it can use 4GB. /klindahl 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. 03/10/2010 - This system accepts more than 2GB if the onboard video adapter is used. If system is equipped with a 3rd party PCIe video card, BIOS will see the memory, but will only allow 2GB to be used. /erivas
