Who need 82430 VX?
1. If you want to get the best performance.
(Because more buffers & Quick DRAM Timing is supported.)
2. If you need a USB ports for C&C application.
(Because 2 USB ports will be ready in the end of Q2/96".)
Why do you need GA-586VX 82430VX motherboard?
1. Because it is the best performance motherboard. (See next page) We have
compared GA-586VX with PC Magazine EDITOR choice-system.
2. Because GA-586VX has 2 banks Sync. DIMM Module, you may upgrade
your memory easily with flexibility.
Others don't, because they only have 1 bank Sync. DIMM Module.
3. Just plug a 256KB Pipeline cache module, and you can get cache size upto
512KB easily. No jumper setting needed.
Others don't, because they don't have an upgrade cache module. Or they
have to change jumper setting to 512KB.
4. No risk for Intel P55CT CPU upgrade because GA-586VX will auto detect
P55CT and support right operation voltage.
Others don't, because they need an EXTRA VRM module or jumper setting
for P55CT CPU upgrade.
5. DIP switch setting is supported. You don't have to worry any jumper shunter
missed.
Others don't, because they have jumpers on board.
