Acer V30 Motherboard

Jumper and Connector Layout

V30-1 Motherboard Diagram

System Overview

  • P54C Pentium Processor support for P75/P90/P100/P120/P133 (VR and VRE)
  • Peripheral Component Interconnect (PCI) Local Bus
  • Triton Chipset ==> 100MB/sec PCI -> DRAM Bandwidth
  • 5 PCI Masters Supported
  • Local Bus Enhanced IDE Bus Mastering Integrated in Triton chipset
  • Plug-n-Play BIOS
  • EPA (Standby/Suspend Modes)
  • Baby AT Form Factor for Mini-Tower Configurations
  • CPU Socket: Zero Insertion Force (ZIF) Socket 5
  • System Clock: 25/30/33 Mhz

MORE INFORMATION

  • CPU Upgrades:
    • Upgradeable to All Future Pentium Overdrive
    • Processors w/ZIF Socket 5
    • Connector (P54CT/P54CST)
  • PCI Local Bus: >100MB/sec Actual PCI to DRAM Data Rate
  • Cache: The V30 ships with 256k write-back second-level cache, and is not upgradable.
  • Video Cards:
    • STB Nitro - Field Upgradeable to 2MB of DRAM (256K x 16 DRAM), Based on Cirrus Logic 5434 Accelerator Chip
    • STB Horizon - Upgradeable to 2 mb with DRAM kit, Based on Cirrus Logic 5430 Accelerator Chip
  • Memory - 128MB Max 4M + (4 Slots, 72 pin SIMMs, 4/8/16/32MB SIMMs, Single/Double Sided) 60 or 70ns Access Time. With 4 32MB SIMMs, the last 8MB of the last SIMM is lost. EDO DRAM is supported (1-3% performance advantage).
