The 2140 I have can take a maximum of 384 megs of RAM. There is 256 in it right now, running the stock OEM Preload of Windows 95 OSR 2 with the Unofficial Service Pack. However there are a couple of things I notice; the first is when the system starts and plays the startup sound, it plays find for the first few seconds and then stutters terribly. The other I notice is that for example a game like StarCraft 1.16, the video performance is terrible despite the onboard graphics (Trident 2 MB) supposedly having enough oomph. Now I do have a PCI TNT2 coming in the next few weeks.
