FAQs

Q: How does the 5218N compare to the 5218?
A: Both have 16 cores, 2.3 GHz base, and 22 MB L3. Platform selection and licensing typically drive choice; consult your server’s CPU support list.

Q: Is this CPU drop-in compatible with LGA3647 boards?
A: Yes, if the motherboard/BIOS supports the 5218N specifically; always check the vendor’s CPU compatibility list.

Q: What memory configuration is recommended?
A: Populate all six memory channels per socket with matched ECC DDR4 DIMMs to maximize bandwidth and stability.

Q: Can I mix 5218N with other CPU models in the same server?
A: Use matched CPUs (same model/stepping) for multi-socket configurations to ensure stability and support.
