This is the motherboard i have

and this is the memory i want to use for it

http://www.ebay.co.uk/itm/DDR2-1GB-800MHz-NON-ECC-CL6-Memory-module-/130629995636?pt=UK_Computing_ComputerComponents_MemoryRAM_JN&hash=item1e6a278c74

now would this work? especialy since that memory is 800mhz and my mb only supports 400/533 mhz

Thank you

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.
