TE430VX Motherboard Technical Product Specification
10
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.

1.4.1 Microprocessor 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

1.5.1 System 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.

1.5.1.1 EDO 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.
