Targeted DDR4 upgrade kit

This 16 GB kit contains two 8 GB DDR4 SODIMM modules rated at 2400 MHz with CL17 timing. It is built for HP ProBook 470 G3, 470 G4, 640 G2 and 645 G3 notebooks that accept 260-pin unbuffered non-ECC memory. The kit raises the system to its supported memory ceiling in a single step.

260-pin DDR4 SODIMM form factor

Each stick uses the 260-pin SO-DIMM layout required by the listed ProBook models. The modules run at 1.2 V and carry a 2Rx8 organisation with major-brand chips. Installing a different pin count or voltage would prevent the laptop from booting.

Steady throughput at rated speed

Under sustained workloads the memory maintains its 2400 MHz data rate and 17-17-17 timings without thermal throttling, because the modules have no heat spreader and rely on the notebook’s internal airflow. The unbuffered design keeps latency consistent during long compile, rendering or multitasking sessions.

Spurningar um þessa vöru

Will 2400 MHz DDR4 run at full speed in a ProBook 470 G3?

The ProBook 470 G3 supports DDR4 2400, so the kit operates at its rated 2400 MHz without downclocking.

Is this kit compatible with the 260-pin SODIMM slots in the listed HP models?

Yes, each module is a 260-pin DDR4 SO-DIMM, matching the slot type used in the ProBook 470 G3, 470 G4, 640 G2 and 645 G3.

Do the modules need a heat spreader to fit inside a ProBook 640 G2?

No, the sticks have no heat spreader, keeping them low-profile for the tight SODIMM bays in the 640 G2.
