STEPS TO TAKE TO PREVENT STATIC DISCHARGE: 1. The best way to prevent static discharge is to buy an anti-static strap from your local electrical shop. While you are wearing the strap and it is earthed, static charge will be harmlessly bled to ground.

• Jumper settings CAUTION Do not move any jumpers with the power on. Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Otherwise, the board could be damaged. Intel 82945P Intel 82801G I/O Controller Hub (ICH7)
System Memory The boards have four DIMM sockets and support the following memory features: • 1.8 V DDR2 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. •...

Memory Configurations • The Intel 82945P MCH supports two types of memory organization: • Dual channel (Interleaved) mode. This mode offers the highest throughput for real world applications. Dual channel mode is enabled when the installed memory capacities of both DIMM channels are equal.
Page 12
Dual Channel (Interleaved) Mode Configurations Figure 7 shows a dual channel configuration using two DIMMs. In this example, the DIMM0 (blue) sockets of both channels are populated with identical DIMMs. Figure 7. Dual Channel (Interleaved) Mode Configuration with Two DIMMs Figure 8 shows a dual channel configuration using three DIMMs.
Page 13
Single Channel (Asymmetric) Mode Configurations NOTE Dual channel (Interleaved) mode configurations provide the highest memory throughput. Figure 10 shows a single channel configuration using one DIMM. In this example, only the DIMM0 (blue) socket of Channel A is populated. Channel B is not populated. Figure 10.

Installing & Removing DDR2 SDRAM In-line Memory Modules (DIMMs) Installing Memory You can install from 128MB to 4GB of memory in the motherboard DIMM sockets. The board has four 240-pin DDR2 SDRAM DIMM sockets. The motherboard supports the following memory features: •...
Removing Memory To remove a DIMM, follow these steps: 1. Observe the precautions in " Upgrading and ESD precautions”. 2. Turn off all peripheral devices connected to the computer. Turn off the computer. 3. Remove the computer cover. 4. Gently spread the retaining clips at each end of the socket. The DIMM pops out of the socket.
