4GB DDR3 SODIMM for HP ProBook 4540S and 4545S

This 4GB module uses 204-pin DDR3 SO-DIMM form factor running at 1333MHz PC3-10600. It is unbuffered non-ECC memory rated at CL7 7-7-7 timing and 1.5V operation. The stick carries major-brand chips and is validated for the listed HP ProBook models.

Suits owners upgrading compatible ProBook notebooks

The single 4GB rank fits systems that accept DDR3 SO-DIMM modules up to the platform limit. Buyers whose laptop requires ECC registered memory or a different pin count cannot use this module. Systems already at maximum supported capacity will not benefit from adding another stick.

Speed grade DDR3 1333 PC3-10600 determines fit

The module operates at 1333MHz with PC3-10600 bandwidth rating. If the target notebook specifies a different DDR3 speed grade or requires 1600MHz PC3-12800 modules this part may not match the required specification. Verify the exact speed grade before purchase.

Questions about this item

Does this 204-pin DDR3 SODIMM fit the memory slot on an HP ProBook 4540s?

Yes, the module is a 204-pin DDR3 SO-DIMM and the compatible systems list includes the HP ProBook 4540s and 4545s.

What is the correct orientation when inserting this 4GB SODIMM, and what mistake should I avoid?

Align the notch on the module with the key in the slot, press firmly at a 30-degree angle until the clips snap shut; forcing it the wrong way can damage the pins.

Will this 1.5V DDR3 module need any firmware update or replacement after a certain period?

No firmware update is required; the memory is a passive component with no moving parts and carries a limited lifetime warranty from the manufacturer.
