Looking at the specifications sheet (PC3-12800 1600MHz DDR3) looks good to use with W530.

It's fine. The "S" is for SO-DIMM. All laptop memory is SO-DIMM

how do I know the machine is dual-core model or quad-core model? is that i7-????QM is quad-core and i7-????XM is dual-core model?
some memory says it is unbufferred. does that mean it is not as good as bufferred memory? all PC3-12800 1600MHz are unbufferred or just some of them are unbufferred.

You want/need unbuffered. Buffered is related to ECC which you don't have. QM is quad core. XM is quad core (extreme). M is dual core
