Intel® Desktop Board D865PERL Specification Update 5. Clarification of DDR Voltage Section 1.6.1, Memory Features, will change as follows: 1.6.1 MEMORY FEATURES The Desktop Board D865PERL has four DIMM sockets and supports the following memory features: • 2.6 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts • 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. Refer to Section 2.2.1 on page 51 for information on the total amount of addressable memory. • Minimum total system memory: 64 MB • Non-ECC DIMMs • Serial Presence Detect • DDR400, DDR333, and DDR266 SDRAM DIMMs 6. Clarification of Section 2.11.1, DC Loading Clarification to Section 2.11.1, DC Loading, will be added as follows: 2.11.1 DC LOADING Table 43 lists the DC loading characteristics of the board. This data is based on a DC analysis of all active components within the board that impact its power delivery subsystems. The analysis does not include PCI add-in cards. Minimum values assume a light load placed on the board that is similar to an environment with no applications running and no USB current draw. Maximum values assume a load placed on the board that is similar to a heavy gaming environment with a 500 mA current draw per USB port. These calculations are not based on specific processor values or memory configurations but are based on the minimum and maximum current draw possible from the board's power delivery subsystems to the processor, memory, and USB ports. Use the datasheets for add-in cards, such as PCI and AGP, to determine the overall system power requirements. The selection of a power supply at the system level is dependent on the system's usage model and not necessarily tied to a particular processor speed. 22
