Installing and Replacing Motherboard Components

How to Remove the Processor

To remove the processor, follow these instructions:

1.Observe the precautions in “Before You Begin” (see page 21).

2.Disconnect the processor fan cable.

3.Detach the fan heatsink clips.

4.Raise the socket handle completely.

5.Remove the processor.

How to Install Memory

You can install from 32 MB to 512 MB of memory in the DIMM sockets. The board has two DIMM sockets arranged as banks 0 and 1. As shown in Figure 11 on page 26, the DIMM socket closest to the processor is for bank 0. The motherboard supports the following memory features:

✏NOTE

On the CA810 motherboard, the minimum memory required is 64 MB for the Windows NT 4.0 operating system.

For optimal video performance, it is recommended that 64 MB of memory be installed.

∙168-pin 3.3 V DIMMs with gold-plated contacts

∙100 MHz 4-clock unbuffered SDRAM DIMMs

∙Non-ECC (64-bit) memory

∙A minimum of 32 MB (required); a maximum of 512 MB. For optimal video performance, use at least 64 MB of system memory.

∙Module sizes: 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, and 512 MB

∙DIMMs with Serial Presence Detect (SPD) or non-SPD data structure

CAUTION

Because the main system memory is also used as video memory, the CA810 motherboards require 100MHz SDRAM DIMMs even though the processor front side bus is 66 MHz. It is highly recommended that SPD DIMMs be used, since this allows the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted.
