GA-586HX

Who need 82430HX?

1. If you want to get the best performance.
(Because more buffers & Quick DRAM Timing is supported.)

2. If your DATABASE is very imporant.
(Because single bit error correction & Multi-bit error detection is supported.)

3. If you want to use memory more than 64MB.
(Because 512MB memory size cacheable is supported.)

4. If you need more flexibility to upgrade your memory.
(Because 4 banks DRAM is supported.)

5. 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-586HX 82430HX motherboard?

1. Because it is the best performance motherboard, see next page, we

compare GA-586HX with PC Magazine EDITOR choice-system.

2. Because user can easily make you memory cacheable size to 512MB.

Others can't, because they don't have an EXTRA TAG-RAM socket.

3. Because GA-586HX has 3 banks DRAM, you may upgrade your memory

easily & with flexibility.
Others don't, because they only have 2 banks 72-pin SIMM modules.

4. Just plug a 256KB Pipeline cache module, you can get cache size to 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.

5. No risk for Intel P55CT CPU upgrade because GA-586HX 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.

6. DIP switch setting is supported, you don't have to worry any jumper shunter

missed.
Others don't, because they have jumpers on board.
