Intel recommends system integrators use motherboards with the 370-pin socket for the boxed Intel® Celeron® processor. The motherboard must be validated specifically for the Intel Celeron processor. However, if you find it necessary to utilize a Slot-to-Socket Adapter (SSA) (see Figure 1 below), please be aware of the following critical considerations:

• The SSA must be recommended by the motherboard manufacturer for use with this specific processor and motherboard combination
• The SSA must run the processor within Intel's electrical, mechanical, and thermal specifications
• Intel does not validate SSAs for use with Intel branded boards or third-party motherboards

Severe mechanical and electrical damage may occur to the processor, motherboard, or both, if these recommendations are not carefully followed.

SSA AND MOTHERBOARD COMBINATIONS, WHICH CAUSE YOUR PROCESSOR TO OPERATE OUT OF SPECIFICATIONS, WILL VOID THE INTEL PROCESSOR LIMITED WARRANTY AND MAY DAMAGE THE PROCESSOR AND/OR MOTHERBOARD. CONTACT YOUR MOTHERBOARD MANUFACTURER TO ENSURE THEY HAVE TESTED AND VALIDATED COMPATIBILITY BETWEEN MOTHERBOARD, SSA, AND THE INTEL CELERON PROCESSOR IN THE PGA/FC-PGA/FC-PGA2 PACKAGE BEFORE USING ANY SSA/MOTHERBOARD CONFIGURATION.

Note: This information is for reference use by PC integrators only and is provided solely as a convenience.

Integration Precaution
Integrating the Intel Celeron processor into some SSAs may damage the processor and other system components. For specific information of any SSA with your motherboard and processor, please check with your motherboard vendor.

Be aware of processor thermal considerations and mechanical requirements when installing a SSA. Verify that the fan heatsink for the boxed Intel Celeron processor provides sufficient cooling within product specification. Also be sure to meet the mechanical mounting requirements recommended by the manufacturers of the SSA and the motherboard. Violating this recommendation will result in the SSA leaning to one side - which may result in poor electrical connections as well as interference with motherboard components.

Therefore, system integrators must verify the following before using an SSA with a boxed Intel Celeron processor:

1. The SSA is electrically connected and mechanically held secure in the 242-contact slot connector (consider a SSA with a retention mechanism interface) and
2. No motherboard components are adversely affected by installing the boxed processor on the SSA
3. The system BIOS must contain the latest BIOS update for the processor
4. The system must contain the latest BIOS for the motherboard
5. PC integrators should perform substantial testing in the following areas: EMC, environmental, mechanical, and compatibility with the intended applications
