Segun la pagina de Intel:

System Memory Features
The board has two 240-pin DIMM sockets and supports the following memory features:

1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
2 GB maximum total system memory
Minimum total system memory: 128 MB
Non-ECC DIMMs
Serial Presence Detect
DDR2 533 or DDR2 400 SDRAM DIMMs

O sea que no soporta los 800 y esta andando a 533 los 2gb de ram no? ahi los podria emparejar tranquilo con los 512 que tmb van a 533.
O saco la de 512 al choto y dejo solo la de 2gb?
