The Intel® SC450NX Server Platform memory module has 16 dual in-line memory module (DIMM) sockets which support up to 4 GB of EDO/ECC system memory. These sockets are divided into four banks of four sockets labeled A through D on the memory module. These banks support 4:1 interleaving only. All DIMMs within a given bank should be identical. From bank to bank, the Intel® 82450NX PCI set supports different varieties of DIMM size, manufacturer and speed. The BIOS will automatically detect the memory type, size and speed. The SC450NX server platform supports the following memory features:
- 168-pin DIMMs with gold-plated contacts
- Buffered EDO/ECC DIMMs; 50ns or 60ns
- 32 MB: 16Mbit, 4Mx4 DRAM; 2K or 4K refresh
- 64 MB: 64Mbit, 8Mx8 DRAM; 4K refresh
- 128 MB: 64Mbit, 16Mx4 DRAM; 4K or 8K refresh
- 256 MB: 64Mbit, 16Mx4 DRAM; 4K or 8K refresh
- 3.3v memory only
- CAS-before-RAS refresh only
- Single or double-sided DIMMs
- Double-high DIMMs with maximum height of 2.1 inches
- TSOP package only, SOJ is not supported due to spacing
Intel requires strict guidelines to be met before a DIMM vendor is put onto this tested memory list, which includes a description of the testing levels.
