Three beeps indicates a memory error. You can try reseating the memory. Also, if you multiple sticks of memory, try removing all but one, then do the same using each one of the sticks.
Do all 24 of these boards have the same memory (amount and manufacturer)?

As mentioned before, 3 beeps indicates a memory error, and in order to address this please try the suggestions mention below;
- Reseat the memory.
- Make sure that the contacts on the memory and the socket are clean.
- Try removing one bank of memory modules at a time. (Some systems can require a memory module in Bank 0.)
- Try using memory modules from the same manufacturer with the same part number and speed.
- Check for a faulty memory module by trying the memory in a known good system.
