FAQs

Q: Is special power/thermal planning required?
A: Yes. High-core, high-TDP CPUs require adequate power and chassis cooling. Verify your UCS node’s power budget and thermal profile.

Q: What memory is recommended?
A: Qualified DDR5 RDIMMs per the node’s memory QVL and population rules for optimal performance.

Q: Does this CPU require a specific UCS firmware version?
A: Ensure the compute node runs a UCS firmware/BIOS release that explicitly supports the 9745.

Q: What workloads benefit most from 128 cores?
A: Highly parallelized virtualization, containers at scale, and data processing frameworks that scale with core count.
