16GB DDR4 SO-DIMM kit for HP ProBook 640/650 G3-G4

This 16 GB kit contains two 8 GB DDR4 SO-DIMM modules rated at 2400 MHz with CL17 timing. It is built for HP ProBook 640 G3, 640 G4, 645 G4, 650 G3 and 650 G4 notebooks that accept 260-pin unbuffered non-ECC memory. The kit fills both sockets for a total of 16 GB.

Low-voltage operation at 1.2 V

Each module runs at 1.2 V without a heat spreader, keeping power draw modest inside the thin chassis of the supported ProBooks. Unbuffered non-ECC organisation avoids extra buffering latency and draws less current than registered alternatives. The major-brand chipset and 2Rx8 rank layout are validated for the listed models.

Steady throughput under sustained workloads

CL17 17-17-17 timings deliver consistent bandwidth during long compile, rendering or virtualisation sessions. The two-module kit populates both slots, enabling dual-channel operation for the full 32 GB maximum capacity of the platform. No thermal throttling occurs because the modules operate within standard DDR4 voltage limits.

商品問答

How do I install the 260-pin DDR4 SODIMM modules in my ProBook 640 G3, and what step is often missed?

Power off, unplug, and remove the battery if accessible. Open the memory door, insert each module at an angle until the gold contacts are hidden, then press down firmly until both side clips click. The step often missed is pressing evenly on both ends so the clips engage together.

What maintenance or replacement will the CM1024642400SO kit need over its lifetime?

No scheduled maintenance is required. The modules have no heat spreader and run at 1.2V, so dust buildup in the laptop vents is the only factor that can degrade stability. If a stick fails, the limited lifetime warranty from Computer Memory Solutions covers exchange.

What limit appears first when the 16GB dual-rank kit runs sustained workloads on a ProBook 650 G4?

The platform caps total memory at 32GB across two sockets, so this 16GB kit leaves room for another 16GB. The first sustained-use limit is the memory controller's maximum supported speed of 2400MHz; the modules already run at that ceiling, so they cannot scale higher under load.
