Single-channel memory architecture
2 x 240-pin DIMM sockets support unbuffered non-ECC 400/533 MHZ DDR2 memory modules
Maximum HP/Compaq approved memory is 2 GB

What memory modules do you have now? You can only have 2 sticks total, 2GB total (2x1GB) But yes, that memory will work. It will 'slow down' to match the FSB.
