For the 4-series chipset based systems including X200, T400 and W500 series, you have to use 2R*8 4-GiB (SO)DIMMs (those with 16 chips, not 8). For frequency, the chipset supports DDR3-1066 (PC8500), but higher frequencies (PC10600 or PC12800) are also accepted. For voltage, the chipset supports 1.5 V, but most DDR3L (SO)DIMMs support both 1.35 V and 1.5 V voltages. So (theoretically) you can use the 2R*8 PC3L-12800 4-GiB SO-DIMMs in X200.
