Compatibility and service notes
- Use a board whose CPU support list includes the exact OPN/stepping and BIOS. AM3 boards use DDR3; an AM2+ board may support this AM3 CPU with DDR2 only when its vendor documents support.
- Phenom II X4 955 parts exist with differing stepping/OPN and thermal limits. The unlocked Black Edition branding does not guarantee motherboard/VRM support for overclocking.
- Verify the printed OPN rather than relying on “955” alone. Check AM2+/AM3 board BIOS, VRM capability, memory type, and cooler rating; preserve stock clocks and voltage in archival tests.
- Before installation, compare the exact CPU marking with the motherboard maker’s support list, board revision, BIOS minimum, package/socket, power requirements, and memory type. Do not force a package into a socket.
Service & archival record
Verify the printed OPN rather than relying on “955” alone. Check AM2+/AM3 board BIOS, VRM capability, memory type, and cooler rating; preserve stock clocks and voltage in archival tests.
For a collection record, photograph both sides, retain the full model/OPN and date/lot codes, describe package and contact condition, and record the tested motherboard revision, firmware, cooling, memory, and measured operating conditions. Separate measured observations from published limits.
