I just installed the ram. A 1 gig stick of PC3200 with timings of 3-4-4-8, single channel. Booted up the computer windows loaded fine. Tried to open a game to see if the system was stable and it wasn't. Game crashed and windows froze, rebooted and tried the same thing, again a crash but system didn't freeze. Then I changed some setting on my system.ini file. Modified [vcache] to include MaxFileCache=524288. Reboot and the same problems occurred. Then lowered "MaxFileCache=524288" to "MaxFileCache=524200" I did this because some people recommended lowering the last value a bit. Again same problems, games crash windows stays up and running. Lastly I checked [386enh] MaxPhysPage=40000 under the system.ini file. Reboot, same problems. I am running windows 98SE modified with UNOFFICIAL Windows98 Second Edition Service Pack 2.1a from exuberant software. AMD 2700, 1 gig of ram PC3200 single channel, 120 gig hard drive, ABIT NFS7-S2G motherboard, 400W power supply. In the next hour I will be placing back in my two previous sticks of PC3200 256 MB ram, and seeing if the problems go away. If I can't seem to solve this problem, then it looks like I'll have to switch to XP
