FAQs

Q: Is the 6434H compatible with my server?
A: It requires an LGA4677 platform with BIOS/firmware support for 4th Gen Xeon Scalable. Check your server’s CPU support matrix.

Q: Does this CPU include a heatsink or thermal kit?
A: Typically sold as the processor only. Use the server’s approved thermal solution and follow the vendor’s BOM.

Q: Can I mix this CPU with a different model in a dual-socket system?
A: Mixing is not recommended. Dual-socket systems should use identical model, stepping, and microcode-supported CPUs.

Q: What memory does it support?
A: DDR5 ECC RDIMM at up to 4800 MT/s, with 8 memory channels per CPU. Actual speed depends on DIMM population and BIOS.

Q: What workloads suit the H-suffix part?
A: Latency-sensitive and per-core performance workloads such as trading systems, analytics nodes, and application servers.
