Why does my Dell R640 show a memory incompatible error when using mixed DIMMs?

The issue may arise from differences in memory rank, firmware, or PCB revisions between the original and new DIMMs, even if the part numbers match.

If problems persist, you may need to return the new modules for ones that match the original revision. [community thread]
