We were trying to add additional ram from 4 GB to 6 GB on a windows 2003 server and we were advised that the 2003 has a max threshold of 4 GB and it does not use or see anything above that . Windows 2003 has an upper bound of 4 on memory which means the OS does not see (or use) additional memory beyond that point.
Can you advice if this is a right statement ? do we have any specs supporting this ?
And do you have any suggestions advise to overcome this ?
