X7DWE User's Manual 1-4 Special Features Recovery from AC Power Loss BIOS provides a setting for you to determine how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must hit the power switch to turn it back on) or for it to automatically return to a power- on state. See the Advanced BIOS Setup section to change this setting. The default setting is Last State.
Chapter 1: Introduction CPU Overheat LED and Control This feature is available when the user enables the CPU overheat warning function in the BIOS. This allows the user to define an overheat temperature. When the CPU temperature passes this threshold, both the overheat fan and the warning LED are triggered. System Resource Alert This feature is available when used with Supero Doctor III in the Windows OS environment or used with Supero Doctor II in Linux.
X7DWE User's Manual the system malfunctions and you want to turn off the power, just press and hold the power button for 4 seconds. This option can be set in the Power section of the BIOS Setup routine. External Modem Ring-On Wake-up events can be triggered by a device such as the external modem ringing when the system is in the SoftOff state. Note that external modem ring-on can only be used with an ATX 2.01 (or above) compliant power supply.
Chapter 1: Introduction filter to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid problems caused by power surges. 1-8 Super I/O The disk drive adapter functions of the Super I/O chip include a floppy disk drive controller that is compatible with industry standard 82077/765, a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA logic.
X7DWE User's Manual Notes 1-14
Chapter 2: Installation Chapter 2 Installation 2-1 Static-Sensitive Devices Electrostatic Discharge (ESD) can damage electronic components. To prevent damage to your system board, it is important to handle it very carefully. The following measures are generally sufficient to protect your equipment from ESD. Precautions • • • • • • • Use a grounded wrist strap designed to prevent static discharge. Touch a grounded metal object before removing the board from the antistatic bag.
X7DWE User's Manual 2-2 Processor and Heatsink Installation When handling the processor package, avoid placing direct pressure on ! the label area of the fan. Notes: 1. Always connect the power cord last and always remove it before adding, removing or changing any hardware components. Make sure that you install the processor into the CPU socket before you install the CPU heatsink. 2. Intel's boxed Xeon CPU package contains the CPU fan and heatsink assembly.
Chapter 2: Installation 4. Align CPU Pin1 (the CPU corner gold dot marked with a triangle) against the Socket Key socket corner marked with a triangle cutout. (Socket Notch) CPU Key (semicircle cutout) 5. Align the CPU key, the semi-circle cutout below a gold dot, against the socket key, which is the notch on the same side of the triangle cutout on the socket. 6. Once aligned, carefully lower the CPU straight down into the socket. (Do not drop the CPU on the socket.
X7DWE User's Manual Installation of the Heatsink CEK Heatsink Installation 1. Do not apply any thermal grease to CEK Passive Heatsink the heatsink or the CPU die because the required amount has already been applied. 2. Place the heatsink on top of the CPU so that the four mounting holes are Screw#1 Screw#2 aligned with those on the retention mechanism. 3. Screw in two diagonal screws (ie the #1 and the #2 screws) until just snug (-do not fully tighten the screws to avoid possible damage to the CPU.
Chapter 2: Installation 3. Once the CPU is loosened, remove the heatsink from the CPU socket. Screw#1 4. Clean the surface of the CPU and the heatsink to get rid of the old thermal grease. Screw#2 Reapply the proper amount of thermal grease on the surface before you re-install the CPU and the heatsink. Mounting the Motherboard in the Chassis All motherboards have standard mounting holes to fit different types of chassis.
X7DWE User's Manual 2-3 Memory Installation CAUTION Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Also note that the memory is interleaved to improve performance (See step 1). DIMM Installation 1. Insert the desired number of DIMMs into the memory slots, starting with DIMM #1A. The memory scheme is interleaved, so you must install (a) pair(s) of modules of the same type and same speed at a time, beginning with Bank 1, Bank 2 and so on.
Chapter 2: Installation Note 3: Due to memory allocation to system devices, memory remaining available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. (See the Memory Availability Table below.)
