4GB DDR3L 1600 SODIMM

This 4GB DDR3L 1600 SODIMM is built for HP ProBook 470 G0, 470 G1, 640 G1, 645 G1 and 645 G2 laptops. It runs at PC3L-12800 with CL11 latency and 1.35V operation. The module uses a 1Rx8 unbuffered, non-ECC design.

Who should buy and who should not

It suits owners of the listed ProBook models who need a single 4GB stick to fill an empty slot or replace a failed module. Buyers who want more than 4GB per slot, need ECC error correction, or require a different voltage should look at other options.

Deciding specification

The module is a 204-pin DDR3L SODIMM rated at 1600 MT/s with 1.35V and CL11 timing. Confirm your laptop accepts DDR3L SODIMMs at this voltage and pin count before ordering.

Questions about this item

Will the 1600 MHz speed actually run at 1600 MHz in my HP ProBook 470 G0?

The module is rated at DDR3L 1600 (PC3L 12800). Your ProBook 470 G0 memory controller determines the final operating frequency; it will run at the highest speed the platform supports up to 1600 MHz.

Does the 204-pin DDR3L SODIMM fit the memory slot in an HP ProBook 645 G2?

Yes. This is a 204-pin DDR3L SODIMM, which is the standard form factor for the listed ProBook models including the 645 G2.

What clearance does the module need since it has no heat spreader?

The module has no heat spreader, so it uses the standard low-profile SODIMM height and fits the tight slots in the ProBook 470 G0, 470 G1, 640 G1, 645 G1 and 645 G2 without clearance issues.
