Important Notes

• About Testing Levels

The motherboard has two 168-pin DIMM sockets. Memory can be installed in one or two sockets. Minimum memory size is 8 MB. The maximum memory size is 256MB. 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
• 60ns 3.3V EDO DRAM
• 60ns unrestricted CAS Latency 2 unbuffered 4-clock 3.3V SDRAM
• Caching for the first 64 MB of main memory
• 64-bit data path

Memory type, size, and speed can vary between sockets, so EDO and SDRAM can be installed on the same motherboard. Parity (x 72) 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.

DIMM Vendors - EDO DIMMs
EDO DRAM improves memory read performance by holding the memory data valid until the next CAS# falling edge, unlike fast page mode DRAM, which tri-states the memory data when CAS# negates to pre-charge for the next memory cycle. With EDO DRAM, the CAS# pre-charge overlaps the data-valid time, which allows CAS# to negate earlier while still satisfying the memory data-valid window. EDO DIMMs should meet the Intel 60ns 64-bit 3.3v unbuffered EDO DIMM v1.2 specification.

The following tables list DIMMs that have been tested. DIMMs that are not listed should also function properly as long as their specifications are compatible with the devices listed below. In general, DIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.

DIMM Vendors - SDRAM DIMMs
Synchronous DRAM (SDRAM) is designed to improve main memory performance. Unlike fast page or EDO DRAM, SDRAM is synchronous with the memory clock. This simplifies the timing design and increases memory speed because all timing is dependent on the number of memory clock cycles. SDRAM DIMMs should meet the Intel 4-clock 66 MHz 64-bit unbuffered SDRAM DIMM v1.0 specification.

Caution: The board does not support SDRAM DIMMs with an n x 4 DRAM base due to loading anomalies. For example, a DIMM that uses sixteen 16Mbit x 4 devices should not be used.

Note: The Intel CN430TX Motherboard supports unbuffered, 4-clock 3.3V SDRAM DIMMs only. Buffered, 5V, or 2-clock SDRAM DIMMs cannot be used.

The following tables list DIMMs that have been tested. DIMMs that are not listed should also function properly as long as their specifications are compatible with the devices listed below. In general, DIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.
