System Overview
2.3.1 Intel Processor Support
The models covered in this guide can each support an Intel Celeron, Pentium, Core i3, Core i5, or
Core i7 processor. These processors are backward-compatible with software written for earlier
x86 microprocessors and include streaming SIMD extensions (SSE, SSE2, and SSE3) for
enhancing 3D graphics and speech processing performance. Intel processors with vPro
Technology include hardware-based tools that allow corporate IT organizations to remotely
manage and protect systems.
The system board includes a zero-insertion-force (ZIF) H2 socket (LGA1155) designed for
mounting an LGA1155-type processor package.
CAUTION: The CMT, MT, and SFF form factors can support a processor with a TPD rating of up to 95
watts. The USDT form factor can support a processor rated up to 65 watts. Exceeding these limits can
result in system damage and loss of data.
✎
These systems use processor sockets that support 2nd generation Intel Core i3, Core i5, and Core
i7 processors and are not compatible with earlier generations of those processors.
✎
The processor heatsink/fan assembly mounting differs between form factors. Always use the
same assembly or one of the same type when replacing the processor. Refer to the applicable
Maintenance & Service Guide for detailed removal and replacement procedures of the
heatsink/fan assembly and the processor.
