Questions & Answers
Q
What is the HPE DL580 Gen10 Xeon-Gold 5122 (3.6GHz/4-core/105W) FIO Processor Kit?
A
The HPE DL580 Gen10 Xeon-Gold 5122 FIO Processor Kit is a field-installable option containing one Intel Xeon Gold 5122 CPU (3.6 GHz base, 4 cores/8 threads, 11 MB cache, 105 W TDP) validated for HPE ProLiant DL580 Gen10 servers.
Q
Which servers support the HPE DL580 Gen10 Xeon-Gold 5122 FIO Processor Kit?
A
This kit is compatible exclusively with HPE ProLiant DL580 Gen10 models that feature the FIO-capable processor sockets and have the minimum required BIOS revision installed.
Q
What are the performance specifications of the Intel Xeon Gold 5122 processor?
A
Intel Xeon Gold 5122 offers 4 cores, 8 threads, 3.6 GHz base frequency, up to 3.8 GHz Turbo Boost, 11 MB SmartCache and a 105 W thermal design power, delivering consistent enterprise performance.
Q
How do I install the HPE DL580 Gen10 FIO Processor Kit?
A
Power down the server, unplug power, open the chassis, remove the empty FIO socket blank, seat the Xeon Gold 5122 processor, secure its retention bracket, reapply thermal interface material, close the chassis, and update the BIOS.
Q
Does installing this kit require any firmware updates?
A
Yes. Before installation, ensure your system firmware (BIOS and iLO) is updated to the minimum versions specified in the HPE ProLiant DL580 Gen10 Maintenance and Service Guide.
Q
Can I mix the Xeon Gold 5122 with other processors in the same server?
A
No. HPE requires identical processors across all sockets in a DL580 Gen10; mixing Xeon Gold 5122 with different SKUs is not supported and may cause instability.

Q
How does the Xeon Gold 5122 compare to Xeon Platinum processors?
A
Compared to Platinum series, the Gold 5122 offers higher base frequency at fewer cores (4 cores vs. up to 28), delivering stronger single-thread performance but lower overall parallel throughput.
Q
Can I return the processor kit if it doesn’t meet my needs?
A
HPE’s return policy varies by reseller. Typically, sealed field-installed parts can be returned within 30 days of purchase if unopened and accompanied by a valid RMA.
