What does Memtest86 give you? (www.memtest86.com) My inclination is to say a hardware problem. I might try with the 2 * 1Gb of RAM by itself, if you are just running a database, you should be fine. If you are worried you could tune down Oracle in your init.ora file. But isolate the RAM (assuming testing shows no problems).
