HP ProBook memory upgrade

This 4GB DDR3 SODIMM is built for HP ProBook 4525s, 4530s, 4535s, 4540s and 4545s notebooks. It targets owners of those models who need a straightforward capacity increase without changing voltage or form factor.

JEDEC-standard 204-pin unbuffered module

The stick runs at 1.5V with CL9 timing at 1333 MT/s and uses a 2Rx8 organisation. No heat spreader is fitted, so it slips into the standard laptop slot and works within the original thermal envelope.

Replaces a single factory DIMM

The jump is worth it when the system currently runs on less than 4GB total or when a second channel is unpopulated. Buyers who need more than 4GB per slot or who require ECC registered memory should look elsewhere.
