FAQs

Q: What’s the main benefit of the 5218R vs. the 5218?
A: The 5218R increases core count (20 vs. 16) and L3 cache, providing more VM density and throughput at a slightly lower base frequency.

Q: Will this work in any LGA3647 server?
A: It requires platform/BIOS support for the 5218R refresh; check your server’s CPU support matrix and update firmware as needed.

Q: Is a matching CPU required for dual-socket operation?
A: Yes. Use two identical CPUs (same model and stepping) for multi-socket configurations.

Q: Does it include a heatsink?
A: Heatsinks are typically server-specific and may be sold separately. Confirm your bill of materials for required thermal components.

Q: What memory configuration is recommended?
A: Populate all memory channels symmetrically with supported ECC DDR4 DIMMs to achieve optimal bandwidth and stability.
