OSX1222IAA6CZ is the F3 stepping. OSX1222IAA6CS identifies the earlier F2 revision of the same 3.0GHz 1222 SE processor model. BIOS support for the installed stepping must be verified before substitution.

⭐ Recommended Thermal Grease - Sold Separately

Fresh thermal compound should be applied whenever the processor heatsink is removed. This is especially important with the high-power 1222 SE because proper heat transfer is necessary to keep the processor within its intended operating temperature.

✅ Confirmed Compatibility

Compatibility depends on the motherboard revision, BIOS version, processor support list, voltage-regulator capacity, and cooling system. Socket AM2 alone does not guarantee support. Verify that the system is approved for the 3.0GHz Opteron 1222 SE and its 120W/125W thermal class before installation.

⚙️ Fit Notes

✓ This listing includes the processor only. A heatsink, cooling fan, thermal compound, and installation tools are not included unless specifically stated.
✓ This is a high-power SE processor. The system must have a voltage-regulator circuit and cooling assembly rated for the 120W/125W processor class.
✓ Update the system BIOS to the required revision before removing the currently working processor whenever possible.
