FAQs

Q: Is this a good choice for latency-sensitive workloads?
A: Yes. The higher base frequency benefits real-time and low-latency applications compared to higher-core, lower-frequency models.

Q: What memory should I pair with this CPU?
A: Use ECC RDIMM DDR5 qualified for your UCS server; for maximum bandwidth, populate all channels symmetrically.

Q: Does it support PCIe 5.0 devices?
A: Yes, platform-dependent PCIe 5.0 lanes are available via the server motherboard.

Q: Any special cooling requirements?
A: Follow the UCS server’s thermal guidelines; use the server-qualified heatsink and airflow configuration.
