End of Interactive Support
Intel is announcing the end of interactive support for the Intel® AN430TX Motherboard. See the End of Interactive Support Announcement for details.
Important Notes System Memory Combinations 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 and 256 MB for SDRAM. 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 3.3V EDO DRAM
- 66 Mhz unrestricted CAS Latency 2 unbuffered 4-clock 3.3V SDRAM
- Caching for the first 64 MB of main memory
- 64-bit data path
- Single- or double-sided DIMMs in the following sizes:
| DIMM Size | Type | Configuration | Technology | | 8 MB | 60 ns EDS | 1M x 64 | 16 Mbit | | 16 MB | 60 ns EDO | 2M x 64 | 16 Mbit | | 32 MB | 60 ns EDO | 4M x 64 | 16 Mbit | | 64 MB | 60 ns EDO | 8M x 64 | 16 Mbit | | 8 MB | CAS Latency 2 SDRAM | 1M x 64 | 16 Mbit | | 16 MB | CAS Latency 2 SDRAM | 2M x 64 | 16 Mbit | | 32 MB | CAS Latency 2 SDRAM | 4M x 64 | 16 Mbit | | 64 MB | CAS Latency 2 SDRAM | 8M x 64 | 64 Mbit | | 128 MB | CAS Latency 2 SDRAM | 16M x 64 | 64 Mbit |
|
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 - Web Sites
The list below contains vendors that have tested their memory for Intel® AN430TX Motherboards, and that have their products listed on their own website. Please visit their sites to obtain information on their products.

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 precharge for the next memory cycle. With EDO DRAM, the CAS# precharge 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. CAUTION: Due to loading anomalies, using EDO DIMMs with a n x 4 DRAM base in the Intel AN430TX Motherboard is not recommended. For example, a DIMM that uses sixteen 16 Mbit x 4 devices should not 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. | Vendor | Test | Vendor Part Number | Comments | | 1H x 64 (8 MB) | Unbuffered EDO | Non-parity-60ns | None | | 2H x 64 (16 MB) | Unbuffered EDO | Non-parity - 60ns | None | | Micron Technology | Full | MT8LSDT264AG-662C1 | None | | Micron Technology | Full | MT8LD264AG-6 | None | | NEC | Full | MC452AB645F-A10 | None | | Unigen | Full | UG52W6628GSG-6 | None | | 4M x 64 (32 MB) | Unbuffered EDO | Non-parity-60ns | None | | Micron Technology | Full | MT16LSDT464AG-662C1 | None | | Unigen | Full | UG54W6646HSG-5 | None | | 8M x 64 (64 MB) | Unbuffered EDO | Non-parity-60ns | None | | Unigen | Full | UG58W6646HSG-5 | None | | Unigen | Full | UG58W6646HSG-5 | None |

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 16 Mbit x 4 devices should not be used. NOTE: The Intel AN430TX 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. | Vendor | Test | Vendor Part Number | Comments | | 1M x 64 (8 MB) | Unbuffered SDRAM | Non-parity-66Mhz | None | | 2M x 64 (16 MB) | Unbuffered SDRAM | Non-parity - 66MHz | None | | Hitachi | Full | HB526264DB | None | | Micron Technology | Full | MT8LSDT264AG-66CL2 | Rev B only | | NEC | Full | MC452AB644FA67 | None | | Texas Instruments | Full | TM2SN64EPU-12A | None | | 4M x 64 (32 MB) | Unbuffered SDRAM | Non-parity-66MHz | None | | Micron Technology | Full | MT16LSDT464AG-66CL2 | None | | NEC | Full | MC454AD644F-A10 | None | | Unigen | Full | UG54S6608GSG-G0 | None | | 8 x 64 (64 MB) | Unbuffered SDRAM | Non-parity-66MHz | None | | NEC | Full | MC458CB644F-A10 | None | | 16 x 64 (128 MB) | Unbuffered SDRAM | Non-parity-66MHz | None |

DIMM Vendors - SDRAM ECC DIMMs
Error checking and correcting (ECC) memory detects multiple-bit errors and corrects single-bit errors. When ECC memory is installed, the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the Setup program. The BIOS automatically detects if ECC memory is installed and provides the Setup option for selecting ECC mode. If any non-ECC memory is installed, the Setup option for ECC configuration does not appear and ECC operation is not available. The following table describes the effect of using Setup to put each memory type in each supported mode. Whenever ECC mode is selected in Setup, some performance loss occurs. Memory Error Detection Mode Established in Setup Program ECC Disabled ECC Enabled Non-ECC DIMM No error detection N/A ECC DIMM No error detection Single-bit error correction, multiple-bit error detection 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. | Vendor | Test | Vendor Part Number | Comments | | 2M x 64 (16 MB) | Unbuffered SDRAM | ECC-66MHz | None | | 4M x 72 (32 MB) | Unbuffered SDRAM | ECC-66MHz | None | | 8Mbit x 72 (64 MB) | Unbuffered SDRAM | ECC-66MHz | None | | Micron Technology | Full | MT9LSDTAG-662D3 | None | | 4M x 72 (82 MB) | Unbuffered SDRAM | ECC-66MHz | None | | 16Mbit x 72 (128 MB) | Unbuffered SDRAM | ECC-66MHz | None |
