Motherboard Review - ABIT IT5V

Advantages & Disadvantages

The Advantages Of The ABIT IT5V
  • CPU SoftMenu, 'jumperless' design
  • 75 MHz bus speed ability
  • 'turbo frequency' for 66 MHz bus speed
  • supports SDRAM and has two DIMM banks rather than one
  • extremely overclocking friendly, due to SoftMenu
  • very well equipped
  • P55C support
  • Cyrix/IBM 6x86L and M2 support
  • coming with Bus Master Drivers on floppy disk
  • very good quality and high stability, more stable than Asus P/I-P55T2P4 rev. 3
  • high reliability
  • good web site, but difficult to access from the western hemisphere. Often ridiculously slow from here (UK)
  • definitely much better support than Asus
  • easy access to Flash BIOS upgrades
The Disadvantages Of The ABIT IT5V
  • no 83 MHz bus speed option, although it would be brilliant as it supports SDRAM.

Tips And Comments

Recommended BIOS Timing Settings for the Different Bus Speeds

These settings are only for EDO, they are meaningless if you use only SDRAM.

Auto Configuration Disabled
DRAM RAS# Precharge Time 3
DRAM R/W Leadoff Timing 6
Fast RAS# to CAS# Delay 2
DRAM Read Burst (EDO/FP) x222/x333
DRAM Write Burst timing x222
Fast MA to RAS# Delay CLK 1
Fasrt EDO Path Select Enabled
Refresh RAS# Assertion 4 Clks
ISA Clock PCICLCK/3 or 4,
depending on Bus Clck
SDRAM (CAS Lat/RAS to CAS) 2/2
This setting is the only SDRAM setting.
Peer Concurrency Enabled
Passive Release Enabled
Delayed Transaction Enabled (?)

You may have to disable 'Fast EDO Path Select' for 66 or 75 MHz bus speed in case your EDO RAM isn't really fast. Don't care about it in case you are using SDRAM.
