1, 2, or 3 Memory error. Reseat the memory or replace the DIMMs with known good
modules.

cards and re-start the system. If the error still occurs, contact your system
manufacturer. If the beep codes are not generated after the add-in cards
are removed, insert the cards one at a time, booting the system between
each card addition, until the beeps again occur to reveal the malfunctioning
card.

used, the server board may be faulty.
