This board is designed to support processors with a maximum wattage of 65 W. The processors listed above are only supported when falling within the wattage requirements of the board. See the Intel web site listed below for the most up-to-date list of supported processors. For information about… Refer to: Supported processors CAUTION Use only the processors listed on the web site above. Use of unsupported processors can damage the board, the processor, and the power supply. Product Description ..INTEGRATOR’S NOTE Use only ATX12V-compliant power supplies. Refer to For information about Power supply connectors Section 2.2.2.4, page 46 1.5 System Memory The board has two DIMM sockets and supports the following memory features: • 1.5 V DDR3 SDRAM DIMMs with gold plated contacts, with the option to raise the voltage to support higher performance DDR3 SDRAM DIMMs • Dual channel interleaved mode support • Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported. • 4 GB maximum total system memory (with two 2 GB DIMMs). Refer to Section 2.1.1 on page 37 for information on the total amount of addressable memory. • Minimum total system memory: 512 MB • Non-ECC DIMMs • Serial Presence Detect • DDR3 800 MHz, DDR3 1066 MHz, and DDR3 1333 (overclocking required) MHz SDRAM DIMMs Note: DDR3-1333 memory operates at 1066 MHz by default until manually overclocked through the system BIOS. CAUTION Altering PC memory frequency, voltage and/or latency may: (i) reduce system stability and useful life of the system, memory and processor; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system data integrity. Intel has not tested, and does not warranty, the operation of the memory beyond ...
