I am thinking of getting a Jetway JBC530 It says it supports Support DDR2 400/533MHz non-ECC, un-buffered memory Max. 2GB

Is the VS2GSDS800D2 suitable does it have the SPD information for 400/533? Would the VS2GSDS667D2 be a better choice (what are its SPD settings)? As they are the same price (within 40p) I would like to by the faster rated memory as it would give me more options to use it in something else at some point in the future, unless its not going to work.
