Fanuc alarm 914: DRAM PARITY : (BYTE 2)
system alarm · Fanuc 0i-D
What it means
Parity error detected on byte 2 of the CNC's working DRAM. Like the other 91x codes, the control stops immediately because continued execution would use corrupted data. The specific byte number identifies which DRAM bank on the processor board produced the bad parity.
Likely causes
- Failing DRAM bank for byte 2 on the main board
- Power supply transient or poor logic grounding
- Overheating memory devices
