Mainboard MV42N

No. Since there is a voltage difference between DDR and SDR SDRAM, using DDR in conjunction with SDR SDRAM may cause permanent damage to both mainboard and memory used.

When you want to install SDRam memory, please follow pictures as below.

After installing the driver for ATI series AGP 4x VGA card on MV42N mainboard, why do I get a blank screen? Then no matter what I do, system powers up but still blank screen.

Please follow the following steps to avoid the problems :

• Disable AGP 4x mode or change to 2x mode in Bios
• Install O.S
• Install VIA 4-in-1 drivers (4.29V or later)
• Install ATI VGA driver
• Enter to O.S
• Restart the system and go back to Bios Setup to enable AGP 4x mode.
