TE430VX Motherboard Technical Product Specification

1.4 Microprocessor

The motherboard is designed to operate with 3.3 volt Pentium Processors running at 75, 90, 100, 120, 133, 150, 166, and 200MHz. An onboard linear voltage regulator circuit provides the required 3.3 volts from the 5.0 volt tap of the power supply. An on-board jumper enables use of VRE specified processors.

The Pentium processor maintains full backward compatibility with 8086, 80286, i386™ and Intel486™ processors. It supports both read and write burst mode bus cycles and also includes separate 8 KB on-chip code and data caches that employ a write-back policy.

The Pentium processor is an advanced numeric coprocessor that significantly increases the speed of floating point operations, while maintaining backward compatibility with i486DX math coprocessor and complying to ANSI/IEEE standard 754-1985.

This motherboard does not support the keep-out zones around the socket 7 that allow use of a “piano wire” type heatsink clip. Intel recommends using only metal heatsink clips.

1.4.1Microprocessor Upgrade

The motherboard provides a 321-pin Socket 7 ZIF processor socket. Socket 7 supports upgrades to higher performance Pentium OverDrive processors.

1.5 Memory

1.5.1System Memory

The motherboard provides two 168-pin DIMM(Dual Inline Memory Module) sites for DRAM memory expansion. The sockets support 1 Meg x 64 (8 MB), 2 Meg x 64 (16 MB), and 4 Meg x 64 (32 MB) SDRAM DIMM modules and 1 Meg x 64 (8 MB), 2 Meg x 64 (16 MB), 4 Meg x 64 (32 MB) and 8 Meg x 64 (64 MB) EDO(Extended Data Out) DIMM modules. For systems configured with EDO or SDRAM DIMM modules, minimum memory size is 8MB for EDO systems. Maximum memory size is 128MB for EDO systems. Maximum memory size is 64MB for SDRAM systems.

The two DIMM sockets are arranged as Bank 0 and Bank 1. Each bank consists of one socket and a 64-bit wide data path. Bank 0 only, Bank 1 only, or both banks may be populated. EDO and SDRAM may be installed in the same system. The system BIOS automatically detects memory size and type so no jumper settings are required. Gold leaded DIMMs are required to be used when adding system memory.

1.5.1.1EDO DRAM

E D O (or Hyper Page) DRAM improves the DRAM read performance. EDO DRAM holds the memory data valid until the next CAS# falling edge unlike standard fast page mode DRAM, which tri-states the memory data when CAS# negates to precharge for the next cycle. With EDO, the CAS# precharge overlaps the data valid time allowing CAS# to negate earlier while still satisfying the memory data valid window time.
