It sounds like you're "flashing" on other addresses. If you didn't use any termination, try putting 100 ohm resistors in series with the mu'xed address, RAS, and CAS, with the series resistors located close to the drivers. Also avoid long lines, and avoid stubs (i.e. the lines should not have branches, or the branches should be as short as possible).
