Questions about this item

Is the 4 GB module sold individually or as a kit?

It is a single 4 GB DDR3 1333 SODIMM. Adding a second identical stick gives 8 GB in dual-channel mode.

Will the CL9 1333 MHz rating actually run at that speed in my ThinkPad T410?

The T410 memory controller supports 1333 MHz, so the module will operate at its rated CL9 1333 MHz without down-clocking.

Does the 204-pin DDR3 SODIMM fit the L420 and L520 slots?

Yes — the 204-pin DDR3 SODIMM form factor matches the slots in the L420 and L520.
