That motherboard was made for PC2100 DDR266. A PC3200 DIMM *SHOULD* be backward compatible. Depending on the density of the PC3200 memory you might have problems. If you have not bought the memory yet I would go with the PC2100 for sure since the PC3200 will give you no speed gains at all and will be running at PC2100 speeds anyway.
If you already have the PC3200 memory then I would say just give it a shot. The worse case scenario is your machine will not boot up with the higher speed ram installed. Assuming you take all the normal hardware upgrade care and do not physically break anything you can test this memory with no harm to your motherboard.
1.6 System Memory
The Desktop Boards provide the following memory features:
• Two DIMM sockets supporting one of the following10:
2.5 V (only) 184-pin 200/266 MHz Double Data Rate (DDR) SDRAM DIMMs with goldplated
3.3 V (only) 168-pin 133 MHz Single Data Rate (SDR) SDRAM DIMMs with gold-plated
• Unbuffered non-ECC DIMMs only
• Maximum total system memory: 2 GB; minimum total system memory: 64 MB
• Serial Presence Detect (SPD) DIMMs only
• Suspend to RAM
According to your system you have : 512MB DDR333 PC2700 Non-ECC Memory (512MB x 1) (One stick of 512MB)
The motherboard manual says this: System Memory Two 184-pin DDR DIMM slots Supports PC1600/PC2100/PC2700 memory Supports 64Mb/128Mb/256Mb/512Mb technology up to 2GB (This means you can have a total of up to 2 Gigabytes of RAM)
If you upgrade your RAM, you will need to make sure that you get the correct type.
If you want to keep the RAM you have, you will only be able to have 1.5 GB of RAM because you only have two slots to work with. If you want to upgrade to the full 2 GB, you will need to buy 2, 1 GB sticks.
you can upgrade to a max of 2gb on that board. These are your 1gb options: 1GB PC2700 333MHz DDR Memory, 1GB PC2100 266MHz DDR Memory, and 1GB PC3200 400MHz Non-ECC Unbuffered 184-pin DDR DIMM Memory. Install a set of any of these and your off and running.
