My idePad z500 supports 16 GB Ram upgrade, according to Lenovo themselves, so...
i7-3632QM 2.20 4GBx2 (Current, can be upgraded to 8GBx2)
Actually, what okr-man posted was just corresponding the processor in the z580 which is what the Personal Systems Reference (PSREF) sheets
Say, the amount of compatible ram not only depends on the processor, but also the motherboard
