DOCUMENTATION CHANGES

The Documentation Changes listed in this section apply to the

AN430TX Motherboard Technical Product

Specification (Order Number 282955). All Documentation Changes will be incorporated into a future version
of the appropriate AN430TX motherboard documentation.

1.

Revision of Section 1.6.1, Main Memory

This section will be replaced in its entirety as follows:

The motherboard has two 168-pin DIMM sockets. Memory can be installed in one or two sockets. Minimum
memory size is 8 MB. Maximum memory size is 128 MB for EDO memory and 256 MB SDRAM memory.
The BIOS automatically detects memory type, size, and speed so no jumper settings are required.

The motherboard supports the following:

168-pin 3.3 V DIMMs with gold-plated contacts

60 and 66 MHz bus speeds

60 ns 3.3 V EDO DRAM

Unrestricted CAS Latency 2 unbuffered 4-clock 3.3 V SDRAM

Caching for the first 64 MB of main memory

64-bit data path

Single- or double-sided DIMMs in the following sizes:

Memory type, size, and speed can vary between sockets, so EDO and SDRAM can be installed on the same
motherboard. 168-pin parity DIMMs can be installed but are not recommended for the following reasons:

The motherboard does not provide parity checking or ECC

Parity DIMMs cause excessive capacitive loading on memory data and address lines
