2 x 1GB DDR2 667mhz samsung M470T2864Q23-CE6, PC2-5300s-555-12-A3 SO Dimms ?

i bought this ram a week or so ago on the basis of misguided advice only to find out that they are in no way compatible with my PC as they are laptop memory sticks but they have not been touched with human hands and are still in the anti static wrappers they came in they where brought from a reputable store that i have used many times before so i hope they are needed by someone as much as i thought i needed them
