FAQs

Q: Is this CPU dual-socket capable?
A: No. U-series processors are designed for single-socket (1S) platforms only.

Q: Will it work in my UCS server?
A: It targets LGA4189-based Cisco UCS M6 platforms. Verify with your server model and UCS HCL/firmware.

Q: Does it support PCIe Gen4 devices?
A: Yes, it provides PCIe 4.0 lanes on supported UCS platforms.

Q: Is a heatsink included?
A: Usually not. Use the UCS-specific heatsink/air shroud for your chassis.

Q: What memory configuration is recommended?
A: Populate all 8 channels with matching ECC RDIMMs/LRDIMMs to achieve maximum bandwidth at DDR4-3200 where supported.
