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).
