This is the nLite Description "Kernal and related files will not be paged (Disable Paging Executive). This speed up the machine if you have at least 512MB of RAM by reducing the hard drive activity and utilizing more RAM instead. This tweak is kind of a tradeoff: More RAM is used to speed up the system for games but applications may also hand when the available RAM drops too low." Iv'e got a Dell XPS M1710 laptop with a 2Ghz C2D and 2gigs of RAM. I checked off this option on my latest install. Im also using a new set of non-WHQL drivers. I often play C&C 3 with a friend over a gigabit LAN, we play 8-player maps and take on 4-6 computers so the games last a long time and get pretty intense. Since my last format, about 45min in my game has crashed back to desktop twice now (no error message, just shuts down to desktop). I dont think its heat related, im thinking its either the new videocard drivers im using on this option. What do you guys think?
