With the arrival of the Intel Santa Rosa platform, memory manufacturers have released new SO-DIMM memory with 400MHz running speed (DDR2-800). In either one or two gigabyte modules, upgrading the memory does improve performance, especially under the VISTA operating system. Since most currently sold laptops come with one gigabyte of memory and usually at DDR2-533 running speed, upgrading to the newest and fastest DDR2-800 SO-DIMM looks a good way to improve overall system response.
