The
K8N Neo4 Platinum is one nice motherboard.
Are you upgrading
to 2GB or
from 2GB?
What memory do you have on the motherboard now?
To use dual-channel DDR, the same type and density memory modules are necessary, or instability may occur.
For complete peace of mind, you would do well to match the memory that you have in your system now -- unless you intend to remove and replace your current RAM in its entirety.
If you are going to replace all of your existing RAM, MSI recommends the use of Kingston RAM. Have you considered Kingston HyperX DDR500 PC4000?
