What to do about frequent ECC errors on server memory?

Locate the faulty DIMM first: check IPMI or BIOS logs to see which module reports errors, then power off, remove it and swap it for testing. Common causes: physical DRAM damage, poor slot contact, or a failed memory controller on the board. ZhongLianDa offers free on-site testing with professional diagnostic tools, and stocks DIMMs of all major brands and models for immediate replacement.
